# STOWORK — Master Plan

**Working name:** STOWORK (stow + work)
**Tagline:** *"Your whole office. In a carry-on. In under two minutes."*
**Document status:** Concept-stage master plan. Every market size, cost, and financial figure below is a **reasoned concept-stage estimate** built from stated assumptions — not a market-research citation, not a quote, and not an endorsement from any named company. Assumptions are labeled inline so a design engineer, a contract manufacturer, and an investor can each stress-test the reasoning rather than trust a number.

## 1. Executive summary

STOWORK is a **wheeled, airline-carry-on-legal case (55 × 35 × 23 cm) that unfolds into a full three-monitor workstation with broadcast-grade AV in under two minutes**, then folds back to cabin-legal dimensions. It is not a laptop and not a portable monitor. It is a **deployable office**: three thin-film OLED panels on a lift that rises them to seated eye level, a mechanical keyboard and haptic trackpad on a slide-out deck, and a telescoping boom carrying a cardioid mic and a 4K camera at eye level.

**The wedge.** The modern knowledge worker is fast and professional at their desk and slow and unprofessional on the road. The laptop solved portability twenty years ago and has not meaningfully solved *screen real estate, ergonomics, or presence* since. STOWORK attacks exactly the gap a second monitor, an external keyboard, a real mic, and a real camera would fill — but collapses all of it into one wheeled case that sets up in one continuous, mostly gas-strut-assisted motion sequence.

**Two SKUs.**
- **STOWORK Dock** — bring your own brain. One USB4/Thunderbolt cable from a laptop or phone drives all three displays, the AV, and power. Target weight (case only) **7.9 kg**, target MSRP **$1,899**.
- **STOWORK Core** — bring your own *Mac*. A standardized **compute bay** in the base hosts your own **Mac mini, Mac Studio, or mini-PC** on a **device-specific 3D-printed cradle** that drops into a fixed blind-mate power/data/thermal interface. Swap machines by swapping a printed cradle; upgrade forever by reprinting one. Target weight (case only) **8.2 kg**; add your machine (**+0.67 kg** Mac mini / **+2.7 kg** Mac Studio) for a loaded ~8.9–10.9 kg. Target MSRP **$2,199** (no bundled compute — you supply the machine you already own).

**The idea worth building** is the *combination*: a carry-on envelope + a tri-fold (triptych) three-monitor array that nests face-to-face when stowed + a rear multi-bar lift that both raises and re-orients the display to eye level + an integrated pro-AV boom + a bounded, sub-two-minute, few-motion deployment — *and*, on Core, a **standardized compute bay served by a family of interchangeable 3D-printed cradles** that adapt heterogeneous small-form-factor computers to one blind-mate power/data/thermal interface. No single element is unprecedented; the integrated system, packaged to airline-legal dimensions and deployable in ≤110 s, is what makes it original — and the printed-cradle compute bay is a second, independent piece of design originality.

**The ask.** A **$6.5M seed** round to carry the concept through EVT → DVT → PVT, initial tooling, certification (FCC/CE/UL, UN 38.3, airline battery compliance), brand and trademark protection, and a funded crowdfund pre-order launch — reaching a de-risked, production-ready device with committed demand.

## 2. Problem & market

### 2.1 The problem

Remote, hybrid, and travel work strips away everything that makes a professional fast:

- **Screen real estate.** A laptop is one cramped 13–16" panel. Desk workers routinely run two or three.
- **Input.** A mushy chiclet keyboard and a small trackpad versus a real mechanical board and a large haptic pad.
- **Presence.** A downward-tilted laptop webcam and a tinny built-in mic versus an eye-level 4K camera and a cardioid condenser — the difference between "calling from an airport" and "in the studio."
- **Ergonomics.** Screens below eye level wreck posture over a multi-hour session.
- **Setup friction.** Assembling even a partial road rig — stand, external monitor, keyboard, mic arm, cables — is a ten-minute cable-spaghetti ritual most people simply skip.

The status quo answers are partial: a single roll-up portable monitor adds *one* screen and nothing else; a laptop stand fixes height but not screens or AV; a "briefcase PC" of the 1990s was a computer, not an ergonomic multi-display office. Nobody has integrated all of it into one carry-on that deploys in a single motion sequence.

### 2.2 Market sizing (reasoned concept-stage estimates)

> **Method:** We size the population of people for whom a deployable premium road office is plausibly worth ~$2,000, then apply a device value and a refresh cycle. Blended device value assumed **$2,050** (mix of $1,899 Dock and $2,199 Core). Assumed **refresh cycle: 4 years**. Every number below is an estimate derived from the stated assumptions.

**TAM — Total Addressable Market.**
- Assume ~**100M** frequent business travelers among global knowledge workers (management consultants, traveling executives, enterprise sales, auditors, field/sales engineers) who travel ≥8 weeks/year.
- Assume ~**35M** premium digital nomads, remote creators, and location-independent professionals who work from non-office spaces most of the year.
- Addressable population ≈ **135M**.
- Installed-base TAM ≈ 135M × $2,050 ≈ **$277B**. Annualized over a 4-year refresh ≈ **~$69B/year**. *(Ceiling figure — assumes universal adoption of a category that does not yet exist. Treat as an outer bound, not a forecast.)*

**SAM — Serviceable Available Market.**
- Restrict to markets we can sell, ship, warranty, and support first: North America, Western Europe, developed APAC.
- Restrict to the segments with the clearest ROI story (consultants, traveling execs, remote creators, field engineers) and premium purchasing power.
- Assume ~**18M** people in that intersection.
- Annualized SAM ≈ 18M × $2,050 / 4 ≈ **~$9.2B/year**.

**SOM — Serviceable Obtainable Market (5-year).**
- A premium hardware startup captures a sliver, gated by production ramp, not demand. We model bottom-up from a unit ramp rather than a market-share percentage:
  - Year 1: ~600 units (crowdfund fulfillment).
  - Year 2: ~8,500 units.
  - Year 3: ~24,000 units.
  - Year 4: ~34,000 units.
  - Year 5: ~42,000 units.
  - Cumulative ≈ **~109,000 units** over 5 years.
- At blended $2,050 → **~$224M cumulative revenue**, exiting Year 5 at a **~$86M annual run-rate**. This is ~0.9% of annualized SAM — a plausible obtainable share for a category-defining premium device.

**Sensitivity.** Halving adoption still yields a >$43M Year-5 run-rate; the thesis does not require category dominance, only that a small, identifiable set of high-earning travelers value a deployable office at premium-accessory prices.

## 3. Product definition

### 3.1 Physical envelope

**Stowed (IATA carry-on legal).**
- External **55 cm (W) × 35 cm (D) × 23 cm (H)** — inside the common 56 × 36 × 23 cm cabin limit.
- Wheeled spinner case, telescoping pull handle, aluminum-frame clamshell.
- Target weight (case only): **Dock 7.9 kg**, **Core 8.2 kg** (Core adds the compute bay, blind-mate connector block, and one bundled cradle). Add the user's own machine: **+0.67 kg** (Mac mini) or **+2.7 kg** (Mac Studio) — a Studio-loaded Core is **~10.9 kg**. Heaviest concentrated mass (battery, and any docked machine) sits low over the wheels for a stable center of gravity. **Carry-on note:** a Studio-loaded Core at ~10.9 kg exceeds the strict **10 kg** cabin allowance some carriers enforce (much of Europe/APAC); it sits inside typical US-domestic allowances. A Mac-mini-loaded Core (~8.9 kg) clears most limits.

**Deployed.**
- Occupies ~**60 cm deep × 95 cm wide** of a standard desk once the triptych is fanned.
- Requires only a chair and a table. Runs **4–6 h** off internal battery (see §4.5) or AC passthrough.

### 3.2 The three-monitor problem and the triptych fold

A 14" 16:10 panel is ~**31 × 19.5 cm**. Three side-by-side ≈ **93 cm** — far wider than the 55 cm case. The solution is a **tri-fold triptych**:

- The **center panel is fixed** on the monitor bridge.
- Two **wing panels hinge on vertical axes** at the center panel's left and right edges.
- Stowed, the wings **fold flat, face-to-face, over the center panel**, nesting to a stack of ~**31 × 19.5 × 2.4 cm** (three ~1.2 mm OLED laminates plus hinges) that lies flat in the rear compartment of the base.
- Deployed, each wing swings out ~**35°** into a **curved, immersive 3-panel array ~93 cm wide**.

Panels are **thin-film OLED** (2026-plausible: ~**1.2 mm** glass-plastic laminate, matte anti-reflective coat). The spec uses a **uniform 14"** panel for a clean stowed nest; a **16" center** (35 × 22 cm) is offered as a premium option. Combined resolution target: **3 × 2560 × 1600**.

### 3.3 Input

- **Keyboard:** low-profile mechanical **TKL (tenkeyless, 36 cm)** in the front well of the base. TKL + trackpad inline = 36 + 16 = **52 cm**, fitting the **53 cm** interior width exactly. (A full-size keyboard is offered as a variant on a fold-out right wing that carries the trackpad.)
- **Trackpad:** **16 × 11 cm** glass haptic pad, right of the keyboard.
- The keyboard rides a **slide-out tray** advancing ~**6 cm** toward the user for wrist comfort.

### 3.4 Pro AV — the things you lose on the road

- **Microphone:** cardioid condenser capsule on a short **telescoping boom** rising from the top-center bridge of the monitor assembly, angling down toward the user's mouth.
- **Camera:** **4K webcam module** co-located on the bridge at eye level (center-top) — you look *into* it, not down at a laptop.
- **Headphones:** over-ear studio headphones in a molded EVA cradle in the lid, charging on pogo pins (housed, not kinematically deployed).
- **Speakers:** stereo drivers in the base front edge.

### 3.5 Lift / ergonomics

The triptych rides a **rear 4-bar lift linkage** (gas-strut assisted) that **raises it ~12 cm** and **rotates it from flat-stowed (screens up) to vertical**, placing the center of the screen near seated eye level when the case sits on a standard **74 cm** desk.

### 3.6 Power / compute and the two SKUs

- Base holds a **swappable battery pack**, low, over the wheels.
- **Dock SKU:** one **USB4/Thunderbolt** cable to a laptop or phone drives all three displays + AV + power.
- **Core SKU:** a **compute bay** in the base hosts the user's own **Mac mini, Mac Studio, or mini-PC** on a device-specific 3D-printed cradle — the case is a complete desktop that travels with the user's real machine. (This replaces the earlier "built-in ARM module" concept: bring-your-own compute is more powerful, upgradeable, never obsolete, and carries zero bundled-compute cost.)

### 3.7 The compute bay and the swappable 3D-printed cradle (Core's differentiator)

The base is packaged as a **left "engine-bay" third** (compute + battery) and a **right two-thirds workspace** (keyboard forward, monitor triptych + lift at the rear, centered on the seated user). The engine bay is the heart of Core:

- **Standardized compute bay.** A keyed **200 × 200 mm** opening, **100 mm** deep, in the base's left-rear quadrant. It is sized to swallow the tallest supported device — a **Mac Studio at 197 × 197 × 95 mm** — and everything shorter. The bay geometry never changes across machines; only the cradle does.
- **Fixed blind-mate connector block** at the rear wall of the bay: power-in, N× USB4/Thunderbolt, DisplayPort/HDMI to the internal three-display driver board, and a fan-sync line. The *case side is invariant* — the user's machine reaches it through the cradle's captive loom, so a new machine never means a new case.
- **Device-specific 3D-printed cradles (the swap mechanism).** A printed frame drops into the 200 × 200 bay, holds one machine in a pre-fit nested pocket, and routes that machine's ports via a short captive loom to the fixed connector block. **Swap machines = swap the printed cradle.**
  - **Mac mini cradle** — 197 × 197 pocket, 36 mm deep, on a printed riser so the mini's top sits flush with the bay lip; an airflow channel aligns the mini's perimeter intake and rear exhaust.
  - **Mac Studio cradle** — 197 × 197 pocket, ~95 mm deep; a minimal frame, since the Studio nearly fills the bay.
  - **Generic mini-PC cradle** — a **parametric STL**: print to any device's L × W × H and port map (Intel NUC, Framework Desktop, Beelink, etc.).
  - Cradles are **user-fabricable** from an open STL family, or shipped pre-printed. Future machines are a **reprint, not a new case** — the future-proofing story. (The print-layer look is intentional and part of the product identity.)

Reference device dims used throughout: **Mac mini 197 × 197 × 36 mm**, **Mac Studio 197 × 197 × 95 mm**.

### 3.8 Deployment walkthrough (≤110 s budget)

Deployment is a bounded set of mostly gas-strut/motor-assisted single motions, mapped to a normalized deploy parameter **t ∈ [0, 1]**.

| # | Action | Time | Model part(s) |
|---|--------|------|---------------|
| 1 | Lay case flat, unlatch, lid swings back | 0–12 s | `lid` |
| 2 | Raise monitor lift; bridge tilts flat → vertical | 12–40 s | `liftMast`, `monitorBridge` |
| 3 | Fan the two wing monitors open | 40–62 s | `wingLeft`, `wingRight` |
| 4 | Extend mic/camera boom | 62–78 s | `boom` |
| 5 | Slide keyboard tray out, flip trackpad, power on | 78–105 s | `keyboardTray`, `trackpad`, `powerLED` |

**Total: ≤110 s**, with a 5 s buffer against the two-minute promise.

**Named stages** (for UI ticks and hero buttons):

| t | id | Label | Caption |
|------|-----------|--------------------|---------|
| 0.00 | stowed | Stowed | 55×35×23 cm. Airline carry-on legal. |
| 0.15 | opened | Opened | Lay flat, unlatch, lid swings clear. |

## 4. Engineering & mechanism detail

### 4.1 Coordinate frame and load geometry

Right-handed frame, **1 unit = 1 cm**: +X right, +Y up, +Z toward the user. Origin at the center of the base footprint on the table (table at y = 0). The base shell is a box ~**53 (X) × 11 (Y) × 35 (Z) cm**. All rotations are eased over their t sub-range and clamped outside it.

### 4.2 Hinge & linkage design

**Wing hinges (triptych fold).** Each wing pivots on a **vertical (Y) axis** at the respective side edge of the center panel. Stowed, wings sit at ~**+170° / −170°** (folded face-to-face over center); deployed, at ~**+35° / −35°** from the center plane. Design as a **friction-detented barrel hinge** with a hard stop at the 35° deployed angle and a soft over-center detent at the folded position, so the array holds its fan geometry without a latch and closes flat without pinch. Panel edges carry compliant bumpers so the OLED laminates nest without glass-on-glass contact (stowed gap budget ≥ 0.4 mm per interface within the 2.4 cm stack).

**Lift (4-bar linkage).** A rear **four-bar linkage**, gas-strut assisted, simultaneously **translates the display assembly +12 cm in Y** and **rotates the bridge from −90° (flat, screens up) to 0° (upright, screens facing +Z)** over t ∈ [0.15, 0.45]. A four-bar (rather than a straight telescoping mast) is chosen because it couples lift and tilt into one continuous, self-guiding path and lets the gas strut do most of the work — the user guides, gravity and the strut lift. Two struts (one per side) balance the moment and prevent racking.

**Keyboard tray.** Linear rails; the tray advances **+6 cm in Z** over t ∈ [0.85, 1.0]. The trackpad flips ~8° to flat over t ∈ [0.88, 1.0].

**Boom.** A thin telescoping arm rises ~**10 cm** from bridge top-center over t ∈ [0.70, 0.85], then pivots the mic head down toward the user; the camera module sits fixed at eye level on the bridge.

**Compute-bay mechanical interface (Core).** The 200 × 200 × 100 mm bay carries three deterministic features so a printed cradle seats in one drop and blind-mates without the user aligning connectors by hand:
- **Alignment ribs.** Two keyed ribs on adjacent bay walls (one carrying the amber index key) constrain the cradle in X and Z as it descends, so the cradle can only seat in the correct orientation and arrives pre-aligned to the connector block.
- **Quarter-turn latch.** A single quarter-turn cam latch at the bay lip locks the seated cradle down and preloads it against the rear connector block, holding blind-mate engagement under travel vibration. One motion in, one motion out — no tools.
- **Blind-mate connector.** A floating, self-aligning connector block (power + N× USB4/TB + DP/HDMI + fan-sync) with a lead-in chamfer and ±1–2 mm float tolerates print-dimensional variation in the cradle loom; final seating is driven by the quarter-turn latch preload, not by the user pushing the machine home. Because the case-side block is fixed and invariant, only the cradle's short captive loom differs between machines.

### 4.3 Materials

| Region | Material | Rationale |
|--------|----------|-----------|
| Outer shell / frame | Anodized aluminum (matte, dark) over an internal aluminum frame | Stiffness-to-weight, premium feel, doubles as a heat spreader, protects contents as luggage |
| Lift links & hinges | Machined aluminum / steel pins at wear surfaces | Fatigue life at the load-bearing joints |
| Panels | Thin-film OLED, ~1.2 mm glass-plastic laminate, matte AR | Thin nest, low reflection for travel lighting |
| Bridge / boom | Aluminum extrusion + glass-filled nylon end caps | Light, rigid cantilever |
| Interior | Soft-black EVA molding, dust seals | Cradles, cushioning, light ingress resistance |
| Input | PC keycaps, machined-glass haptic trackpad | Durability, tactile quality |

### 4.4 Weight budget

**Dock SKU — target 7.9 kg (7,900 g).**

| # | Component | Mass (g) |
|---|-----------|---------:|
| 1 | Aluminum clamshell shell + internal frame + latches/hinges | 2,250 |
| 2 | Wheels + spinner assembly + telescoping handle | 780 |
| 3 | Triptych: 3× 14" OLED panels + bezels + driver PCBs | 780 |
| 4 | Monitor bridge cross-member + tri-fold wing hinges | 380 |
| 5 | 4-bar lift linkage + 2 gas struts + mast | 620 |
| 6 | Low-profile mechanical TKL keyboard | 500 |
| 7 | Keyboard slide tray + linear rails | 260 |
| 8 | Glass haptic trackpad | 190 |
| 9 | AV boom + mic capsule + 4K camera + flex cabling | 230 |
| 10 | Over-ear studio headphones | 290 |
| 11 | Stereo speaker drivers + sealed enclosures | 220 |
| 12 | Battery pack, 99 Wh Li-ion, swappable | 560 |
| 13 | Mainboard (USB4 host, DP-MST, PD controller, audio DSP) | 280 |
| 14 | Interior molding, EVA cradles, dust seals | 280 |
| 15 | Wiring harness, fasteners, thermal, misc | 280 |
| | **Total** | **7,900** |

**Core SKU (case only) — target 8.2 kg (8,200 g) = Dock + 300 g.**

Core removes the built-in ARM compute module entirely and adds only the compute-bay hardware. The user's own machine is **not** part of the case-only budget.

| # | Added component | Mass (g) |
|---|-----------------|---------:|
| A | Compute-bay structure (keyed walls, alignment ribs, quarter-turn latch) | 130 |
| B | Fixed blind-mate connector block (power + USB4/TB + DP/HDMI + fan-sync) | 80 |
| C | Internal loom / harness from connector block to driver board | 30 |
| D | One bundled 3D-printed cradle (Mac mini or Mac Studio) | 60 |
| | **Added subtotal** | **300** |
| | **Core total (case only)** | **8,200** |

**User-supplied machine (not in case-only budget):** **+670 g** (Mac mini, 197 × 197 × 36 mm) or **+2,700 g** (Mac Studio, 197 × 197 × 95 mm). Loaded Core = **~8.9 kg** (mini) or **~10.9 kg** (Studio). See §3.1 for carry-on weight-limit implications.

### 4.5 Battery & runtime math

**Cell strategy.** Each removable pack is **99 Wh** — deliberately **under the 100 Wh airline threshold** so a pack qualifies as carry-on-legal and can be swapped/spared. (Travelers should still confirm carrier policy; IATA permits installed device batteries and, with airline approval, up to two 100–160 Wh spares.)

**Dock load budget:**

| Load | Power |
|------|------:|
| 3× OLED panels @ ~4.5 W typical | 13.5 W |
| DP-MST hub + USB4 retimers | 3.5 W |
| Audio DSP + speakers (moderate) | 2.0 W |
| 4K camera + mic preamp | 2.0 W |
| Controller / misc | 1.5 W |
| **Case load (typical)** | **≈ 22.5 W** |

- **Dock runtime:** 99 Wh ÷ ~22.5 W ≈ **4.4 h**. At minimum brightness (~16 W) ≈ **6.2 h**; with brightness up plus modest host trickle (~24 W) ≈ **4.1 h**. This brackets the **4–6 h** spec.
- **Charging the host laptop.** If the Dock also fast-charges a host at +60 W over USB4, total ≈ 82 W → 99 Wh ÷ 82 W ≈ **1.2 h**. Therefore host charging is intended for **AC passthrough**, not battery; the internal pack is sized to run *the case's own displays and AV*, while the laptop runs on its own battery. This is stated plainly to avoid over-promising.

**Core:** one 99 Wh pack, same as Dock; the case supplies power to the docked machine through the blind-mate connector. Runtime therefore depends on the *user's* machine:
- **With a Mac mini** (idle ~4–7 W, typical desk work ~15–25 W): case ~22.5 W + machine ~20 W ≈ **~42.5 W** → 99 Wh ÷ 42.5 W ≈ **2.3 h** on battery. Light/idle mixed use pushes toward **3 h+**.
- **With a Mac Studio** (typical ~50–100 W, peak far higher): battery operation is impractical; Core with a Studio is intended to run on **AC passthrough**, using the battery only for brief untethered spans and transport.
- A **swappable spare 99 Wh pack** is offered as an accessory to extend untethered mini use; anything Studio-class assumes wall power. This is stated plainly to avoid over-promising a "run a desktop off a battery all day" claim the physics does not support.

### 4.6 Display driver & bandwidth reasoning

Target: **3 × 2560 × 1600 @ 60 Hz** over a single USB4/Thunderbolt cable (Dock).

- Per panel at 2560 × 1600 @ 60 Hz, 24 bpp, reduced blanking: pixel clock ≈ 268 MHz → **≈ 6.45 Gbps** of effective display data.
- Three panels ≈ **19.4 Gbps** effective.
- USB4/Thunderbolt tunnels DisplayPort. DP **HBR3** = 4 lanes × 8.1 Gbps × 0.8 (8b/10b) ≈ **25.9 Gbps** effective available for display tunneling.
- **19.4 Gbps < 25.9 Gbps → all three panels fit at 60 Hz with no compression**, driven by an internal **DP-MST hub** fed from the single host cable.
- **Headroom:** enabling **DSC (~3:1)** frees enough budget to run the triptych at **90–120 Hz** or to add the 16" center-panel resolution option, while leaving USB/data tunneling intact within the 40 Gbps USB4 envelope.

The Core SKU drives the same panels from the docked machine over the bay's blind-mate USB4/Thunderbolt + DP/HDMI lines. A Mac mini or Mac Studio provides its own Thunderbolt display controllers, so the same 19.4 Gbps triptych budget is served directly through the connector block — the fixed internal DP-MST hub fans a single tunneled stream to the three panels exactly as in the Dock path, independent of which machine is cradled.

### 4.7 Thermal

- **Dock (~22 W):** passively cooled. The anodized aluminum shell and internal frame act as the primary heat spreader; low-power OLED and controller heat is dissipated through the shell and unobtrusive rear vents. No fan required in normal operation.
- **Core (docked machine):** the machine keeps its **own cooling** — the bay's job is to not choke it. The **bay floor and rear louvers are aligned to the specific device's intake and exhaust** (set by the cradle geometry, which routes airflow to the right faces), and the **case rear panel has matching exhaust cutouts** directly behind the bay so hot air exits the case rather than recirculating. The Mac-mini cradle channels the mini's perimeter intake / rear exhaust; the Mac Studio cradle clears its front-intake / rear-exhaust path. The **fan-sync line** on the connector block lets the case optionally read the machine's thermal state to modulate any assist venting. Battery and bay are thermally isolated from the input deck and hand-contact surfaces. Because heat generation and cooling live inside the user's machine, Core adds **no compute cooling hardware** to the case — a key simplification versus the old built-in-ARM design.

### 4.8 Structural load paths & stability

- **Primary structure:** the aluminum-framed base shell. The rear compartment carries the lift mounts; loads from the cantilevered display feed through the four-bar pivots into the frame, not the outer skin.
- **Deployed moment:** the display sits ~12 cm up and forward of the rear pivots — a rear-biased cantilever. The **gas struts carry the static holding moment**; the four-bar geometry keeps the load line inside the base.
- **Anti-tip / CG:** the **battery low over the wheels** pulls the center of gravity down and forward, and the 35 cm base depth keeps the deployed CG inside the footprint. A small **fold-down rear stabilizer foot** extends during lift to widen the effective rear base and guarantee no rearward tip when the triptych is up. Deployed system remains stable against a normal desk bump.
- **Stowed as luggage:** closed, the shell is a rigid box rated to survive checked-bag-grade handling even though it is designed to fly in the cabin; internal EVA cradles isolate the panels and AV from shock.

### 4.9 Reliability, cycle life, durability

- **Wing hinges:** target **≥ 50,000 open/close cycles** (fold is low-stress, friction-detented). ~10 deploys/week for 5 years ≈ 2,600 cycles, so 50k is a >18× margin.
- **Lift four-bar & gas struts:** target **≥ 20,000 full lift cycles**; gas struts are a **serviceable, replaceable module** rated and swappable if force decays.
- **Keyboard:** standard mechanical switch rating (tens of millions of keystrokes) — not the limiting item.
- **Boom telescope & keyboard rails:** ≥ 20,000 cycles, self-cleaning wipers on the rails.
- **Ingress/durability:** not a sealed ingress-protection-rated device, but **dust- and splash-resistant** for travel (seals on the closed clamshell, gasketed vents). Panels behind matte AR laminate resist scuffing; corners take impact via the aluminum frame.
- **Compute bay (Core):** the quarter-turn latch and blind-mate connector target **≥ 5,000 insertion/latch cycles** — far above the swap frequency of a machine a user upgrades every few years. The printed cradle is a **consumable/accessory**, not a wear-limited structural part; a cracked or outgrown cradle is simply reprinted or reordered.
- **Serviceability:** battery packs, gas struts, keyboard, AV boom, and (Core) the compute-bay cradle are **field- or depot-replaceable modules** to protect warranty economics and extend product life. Because the docked computer is the user's own, its failure or upgrade is fully decoupled from the case.

## 5. Design & differentiation

> STOWORK's edge is not a single trick — it is the **combination**, executed to a hard specification. The argument below is why the integrated system is original, why it is difficult to copy well, and where the durable brand/quality moat sits. No element in isolation is unprecedented; the value is in making all of them work together inside an airline-carry-on envelope that deploys in under two minutes.

### 5.1 What STOWORK actually is (the design in one line)

*A wheeled carry-on-legal case (on the order of 56 × 36 × 23 cm) that reconfigures into a full workstation:* a **tri-fold triptych** of a fixed center display panel plus two wing panels hinged on vertical axes that fold face-to-face over the center for stow and fan outward into a curved multi-panel array; a **gas-strut-assisted multi-bar lift** that both raises the display and rotates it from face-up-stowed to user-facing-upright at seated eye level; an **AV boom** on the display bridge carrying a microphone and a camera; a stowable **keyboard + haptic trackpad deck**; and, on Core, a **standardized in-base compute bay served by a family of interchangeable 3D-printed cradles** that adapt heterogeneous third-party small-form-factor computers to one fixed blind-mate power/data/thermal interface — all reconfiguring between a closed carry-on state and a deployed multi-display state in ≤110 s.

### 5.2 The two original ideas

**A. The deployable-office system.** The design idea is that the product is a *deployable office*, not a better laptop — and that this can be packaged to cabin-legal dimensions and set up in one continuous, mostly strut-assisted motion sequence. That reframing is what forces every downstream engineering choice.

**B. The modular printed-cradle compute bay.** A separate and self-standing design idea: the hard part of "put any small desktop inside the office" is not the enclosure but the **adapter layer**. STOWORK solves it with a *fixed, invariant* in-case interface plus a *family of printable, user-fabricable cradles*, so the class of usable machines is extended by printing a cradle rather than by redesigning the case. This is what makes Core forward-compatible with computers that do not yet exist. It stands on its own even if the display system were removed.

### 5.3 Why it is hard to copy — the engineering constraints do the work

Each ingredient exists somewhere, but integrating them under the **airline-carry-on constraint** forces non-trivial, coupled trade-offs that a casual clone will get wrong:

- The triptych **must** nest face-to-face to fit the 55 cm case — three ~1.2 mm OLED laminates into a ~2.4 cm stack with compliant bumpers and no glass-on-glass contact.
- The lift **must** both raise (~12 cm) *and* re-orient (~90°) to reach eye level from a flat-stowed panel, which is why a coupled four-bar linkage beats a straight telescoping mast.
- The AV **must** ride the display bridge to land the camera at eye level and pivot the mic to the mouth.
- The whole reconfiguration **must** complete in ≤110 s in few, mostly strut-assisted motions to be usable, and **must** fold back to cabin-legal dimensions.

The specific arrangement that satisfies *all* of these at once — nested triptych + coupled lift + bridge-mounted eye-level AV + bounded deploy, inside a carry-on — is the design achievement. Anyone starting from "a portable monitor plus a dock" does not arrive here; the constraints only resolve if you set out to build a deployable office from the first sketch.

The compute bay is separately hard to copy well: a purpose-built single-device enclosure is easy, but a *standardized bay + fixed blind-mate interface + interchangeable printed-cradle family* is a different abstraction. The float-tolerant blind-mate connector (±1–2 mm), the one-drop alignment-rib-plus-quarter-turn-latch retention, the airflow registration per device, and a *parametric* cradle model that a user can reprint for a machine that does not exist yet — that whole system is the differentiator, and it is a deliberate design decision, not an accident of packaging.

### 5.4 Against the alternatives

| Alternative | What it does | What STOWORK does that it does not |
|-------------|--------------|-------------------------------------|
| Laptop | Portable compute, one cramped screen | Three eye-level panels, real input, broadcast AV, ergonomic lift — a full office, not one panel |
| Portable / roll-up external monitor | Adds a single screen | A curved multi-panel array, lift-to-eye-level, integrated input + AV; a self-contained deployable office |
| Laptop dock / docking station | One cable driving desk peripherals you already own | Brings the displays, ergonomics, and AV *with you* in the case; on Core, hosts a whole desktop in a receptacle rather than tethering an external one by cable |
| 1990s "briefcase PC" / luggable | A computer packaged in a case | Fold-out multi-display, eye-level AV, sub-2-minute few-motion deploy, and cabin-legal fold-back — an ergonomic office, not a boxed computer with one fixed screen |
| eGPU / mini-PC / NUC enclosure | Houses one specific computer | A standardized bay + printed-cradle family adapting *heterogeneous* machines to one fixed interface, inside a deployable multi-display workstation |
| 3D-printed device mount / VESA bracket | Passive holder for one device | A keyed in-case bay with a blind-mate power/data/thermal interface, as part of the workstation — not a passive bracket |

### 5.5 The durable moat: brand, quality, and ecosystem

Design originality gets STOWORK to market; it is **execution quality and ecosystem** that keep it there.

- **Tolerance-critical mechanisms.** The nested triptych, the coupled lift, and the blind-mate bay are all *fit-and-finish* problems. Hitting ≤110 s deployment, a rattle-free stow, and reliable one-drop blind-mate under travel vibration takes real mechanical iteration (two-plus hinge/linkage cycles through EVT/DVT/PVT). A fast follower can copy the concept sketch far more easily than the feel.
- **The cradle ecosystem as a flywheel.** An open, published STL cradle family plus pre-validated cradles for popular machines makes STOWORK the *default* case an owner keeps across three computer upgrades — each upgrade is a **$15–35 reprint**, not a new purchase. Community-contributed cradles for long-tail machines deepen the moat the same way an accessory ecosystem does, and seed forward-compatibility for hardware that ships later.
- **Brand and category ownership.** Being first to define and demonstrate the "deployable office in a carry-on" category — the two-minute live deploy is its own advertisement — earns the association that a later clone has to fight for. Premium industrial design, the intentional printed-cradle aesthetic, and a coherent quality story compound into a brand that a spec-sheet copy cannot cheaply match.

### 5.6 Concept assets to produce

To make the design case tangible for manufacturing and investment review, the concept should be captured as:

1. Isometric of the closed carry-on (stowed silhouette, wheels, handle).
2. Exploded view: base, lid, lift, triptych, boom, input deck.
3. Section through the triptych fold (stowed nest) with the ~2.4 cm stack callout.
4. Four-bar lift kinematics across t = 0.15 → 0.45 (raise + rotate).
5. Wing-hinge deployment, top view, showing the ~35° fan and curved array.
6. AV boom extension and mic pivot / camera eye-level geometry.
7. Deployment sequence storyboard mapped to the ≤110 s stages.
8. Power/signal architecture: Dock (single cable + DP-MST) vs. Core (docked machine → blind-mate interface → DP-MST).
9. **Compute bay & cradle (the differentiator):** section through the 200 × 200 × 100 mm bay showing alignment ribs, quarter-turn latch, and the fixed blind-mate connector block; an exploded view of a device seated in its printed cradle dropping into the bay; and a comparison plate of the Mac-mini (36 mm), Mac-Studio (95 mm), and parametric mini-PC cradles seating in the *same* bay, with the airflow/exhaust registration called out.

### 5.7 Brand & naming

- Secure the **STOWORK** name and clear the mark in target regions early — the category-defining name is part of the moat.
- Treat firmware, the deploy-sequence tuning, and the panel-driver calibration as closely-held know-how, refined through prototyping, that is not obvious from the outside of the product.

## 6. Manufacturing & DFM

### 6.1 Indicative BOM (Dock, ~25k units/yr)

> Rough cost bands at mid-volume; final costs depend on panel sourcing and tooling amortization. Estimates, not quotes.

| Line item | Est. cost (USD) |
|-----------|----------------:|
| 3× 14" thin-film OLED panels + drivers (~$70 ea) | 210 |
| Aluminum enclosure (extrusion/CNC + anodize) + frame | 95 |
| Mainboard (USB4/TB retimer, DP-MST, PD, DSP, PCB) | 72 |
| Battery pack, 99 Wh (cells + BMS + housing) | 58 |
| 4-bar lift linkage + gas struts + mast | 42 |
| AV: 4K camera + cardioid mic + boom mechanism | 38 |
| Tri-fold hinges + monitor bridge (cycle-rated) | 34 |
| Over-ear headphones | 34 |
| Low-profile mechanical keyboard | 32 |
| Wheels + spinner + telescoping handle | 28 |
| Glass haptic trackpad | 26 |
| Molding, EVA, dust seals, fasteners | 22 |
| Wiring, connectors, flex | 18 |
| Stereo speakers + amp | 16 |
| Packaging | 14 |
| **Dock BOM total** | **≈ 739** |

**Core adds (and drops the ARM module entirely):** compute-bay structure (bay walls, alignment ribs, quarter-turn latch) **~$22**, fixed blind-mate connector block (power + USB4/TB + DP/HDMI + fan-sync, floating connector + routing PCB) **~$26**, internal loom/harness **~$9**, one bundled 3D-printed cradle **~$3** → **+~$60** → **Core BOM ≈ $799**.

> **Cradles are near-free.** A printed cradle is a **low-cost printed part** — filament + machine time on the order of **~$1–3 marginal COGS** each, versus the >$100 an integrated compute module used to add. Beyond the one bundled unit, the cradle family is a **standalone accessory / ecosystem revenue line**: extra cradles for a second machine, upgrade cradles when the user buys a newer Mac, and an open published STL set for community/enthusiast printing (which also seeds forward-compatibility with machines that do not yet exist). This turns "your computer got faster" from an obsolescence event into a **$15–35 accessory reorder**.

### 6.2 Loaded COGS, MSRP & margin

| | Dock | Core |
|---|-----:|-----:|
| BOM | $739 | $799 |
| Assembly + test | $45 | $48 |
| Freight + duty | $60 | $62 |
| Warranty + scrap reserve | $35 | $36 |
| **Loaded COGS** | **≈ $879** | **≈ $945** |
| **Target MSRP** | **$1,899** | **$2,199** |
| **Gross margin** | **~54%** | **~57%** |

Margins are healthy-but-honest for premium D2C hardware and leave room for channel/retail discounts on a portion of volume. **Core's economics improved versus the old built-in-compute plan:** dropping the ARM module (and its cooling, second battery, and I/O board) cut ~$264 of bundled cost down to ~$60 of bay/connector hardware, so Core can price at **$2,199** — only $300 over Dock, with the user's *own* Mac supplying the compute — and still hold a ~57% margin. Cradle accessory sales carry near-100% gross margin on top.

### 6.3 Suppliers by category

- **Displays:** thin-film OLED module houses (Tier-1 panel makers with laminated-OLED lines).
- **Mechanisms:** precision hinge and gas-strut specialists (furniture/automotive-grade fatigue expertise); CNC/extrusion aluminum houses.
- **PCBA / electronics:** contract EMS for the mainboard, USB4/DP silicon vendors, PD/BMS suppliers.
- **Battery:** UN 38.3-certified pack assemblers.
- **AV:** camera-module ODMs, MEMS/condenser mic vendors, audio DSP.
- **Compute bay (Core):** blind-mate / floating-connector vendors (rack-mount and hot-swap-drive suppliers), latch/hardware specialists, and a **fleet-3D-printing** partner (SLS/MJF or high-quality FDM) for bundled cradles and accessory reorders — with the same STL set published for user self-printing.
- **Case hardware:** premium luggage OEMs (wheels, handles, shells).
- **Final assembly:** a single contract manufacturer with mechatronics + battery + display integration capability (China / Vietnam / Mexico options for tariff hedging).

### 6.4 Assembly steps (high level)

1. Fabricate + anodize shell and frame; install wheels, handle, latches.
2. Sub-assemble the triptych (panels + wing hinges + bridge), functional-test each panel.
3. Sub-assemble the four-bar lift + gas struts; verify lift force curve and travel.
4. Sub-assemble the AV boom; verify extension + mic/camera.
5. Populate + test the mainboard; integrate battery pack (safety test).
5a. **(Core only)** Install the compute-bay structure, fixed blind-mate connector block, and internal loom; verify blind-mate continuity and float, quarter-turn latch preload, and a cradle-seat/unseat check. Bundle one printed cradle (matched to the customer's declared machine, or ship the parametric STL).
6. Integrate lift + triptych + AV into the base; route harness.
7. Install input deck (keyboard tray, trackpad), headphones cradle, speakers.
8. Full-system deploy test (stowed → ready), display/AV/power functional test, ≤110 s deploy-time check.
9. Cosmetic QC, pack-out.

### 6.5 Tooling / NRE

Estimated **~$3.8M** total: injection molds (interior moldings, trims), CNC + anodize fixtures, custom OLED panel and hinge tooling/NRE, PCBA stencils and test jigs, certification (FCC/CE/UL, UN 38.3 battery, airline compliance), and EVT/DVT/PVT build costs.

### 6.6 Quality plan

Incoming inspection on panels/cells; 100% functional deploy + power + AV test at end of line; sampled cycle-life audit on hinges and lift; battery safety per UN 38.3; ORT (ongoing reliability testing) on deploy cycles; field-failure feedback loop into revisions.

### 6.7 Prototyping path

- **Looks-like:** appearance model — form, size, weight feel, stowed silhouette. Validates the carry-on envelope and industrial design.
- **Works-like:** functional rig proving the triptych fold, four-bar lift kinematics, and ≤110 s deploy — likely two hinge/linkage iterations.
- **EVT:** first integrated electronics + displays + AV + battery; validate bandwidth, thermal, runtime.
- **DVT:** design validation on production-intent tooling; reliability and certification testing.
- **PVT:** production validation on the line; yield, cycle time, cosmetic QC — then ramp.

## 7. Go-to-market

### 7.1 Segments

| Segment | Why they buy | SKU lean |
|---------|--------------|----------|
| Management consultants / traveling execs | Bill by the hour, present constantly, live on the road | Dock (already carry a powerful laptop) |
| Remote creators / streamers | Need eye-level 4K + real mic + multi-screen anywhere | Core (bring a Mac Studio) or Dock |
| Field & sales engineers | Demos, multi-window work in the field | Core (bring a Mac mini / mini-PC) |
| Digital nomads | Full office in any rental / café / hotel | Dock or Core |
| Mac-first professionals | Already own a Mac mini / Mac Studio and want it to travel | Core (dock the machine they already own) |
| Enterprise "road warrior" fleets | Standardize a professional remote setup | Dock (fleet + MDM) |

### 7.2 Pricing & positioning

- **Dock $1,899** — "your laptop's whole office in a carry-on." Positioned *above* portable-monitor + accessory stacks, *as* the category-defining deployable office.
- **Core $2,199** — "**bring your own Mac.** The workstation that travels with your real machine." Only **$300** over Dock because there is **no bundled compute** — the customer supplies the Mac mini / Mac Studio / mini-PC they already own, dropped into a printed cradle. The hook: *swap machines by swapping a printed cradle, and upgrade later by reprinting one* — the office never goes obsolete when the computer does. Positioned against a desktop-Mac-plus-monitors setup that can't leave the desk, and against the old "buy a whole new integrated computer" model this design replaces.
- Positioning line vs. status quo: a portable monitor adds *a screen*; a laptop stand adds *height*; STOWORK adds *the office* — screens, ergonomics, input, and presence — in one motion; and **Core lets your own desktop Mac come with it, then follow you through every future upgrade for the price of a reprinted cradle.**

### 7.3 Channel

1. **Crowdfund pre-order launch** — proves demand, funds the first run, builds the founding community.
2. **D2C web** — primary margin channel, controls the brand story and the two-minute demo video.
3. **Premium retail & travel-retail** (airport concept stores, design retailers) — the product demos itself; a live deploy is the ad.
4. **Enterprise / fleet** — MDM-friendly Dock bundles for consultancies and field organizations.
5. **Cradle accessory store / ecosystem** — a small, high-margin D2C line: extra and upgrade cradles for Core owners, plus a published open STL library for self-printing that seeds forward-compatibility and community goodwill.

---

## 8. Financials & the ask

> Concept-stage estimates. Directional shape, not a forecast.

### 8.1 The raise

**$6.5M seed** to reach a de-risked, production-ready device with committed demand (funded crowdfund pre-orders), positioning a Series A to fund volume production.

### 8.2 Use of funds

| Category | Amount |
|----------|-------:|
| Engineering team (mech, EE, firmware, ID) — 18 mo | $2.6M |
| Prototyping (EVT/DVT/PVT builds + iterations) | $0.9M |
| Tooling & NRE (soft tooling + long-lead OLED/hinge) | $1.4M |
| Certification & brand (FCC/CE/UL, UN 38.3, airline, trademark) | $0.6M |
| GTM / crowdfund campaign + brand | $0.5M |
| G&A, ops, contingency | $0.5M |
| **Total** | **$6.5M** |

### 8.3 Milestones tied to funding

1. Works-like prototype: triptych + lift + ≤110 s deploy proven.
2. Industrial design locked; STOWORK trademark cleared in target regions.
3. EVT: bandwidth, thermal, runtime validated.
4. Crowdfund launch with a funded pre-order book.
5. DVT on production-intent tooling; certifications underway.

### 8.4 Rough P&L shape (5-year, illustrative)

| Year | Units | Revenue | Gross margin | Net (approx.) |
|------|------:|--------:|-------------:|--------------:|
| 1 | ~600 (crowdfund) | ~$1.2M | — (dev year) | ~ −$5.0M |
| 2 | ~8,500 | ~$17.4M | ~50% | ~ −$2.5M |
| 3 | ~24,000 | ~$49.2M | ~55% | ~ +$2.0M |
| 4 | ~34,000 | ~$69.7M | ~56% | ~ +$8M |
| 5 | ~42,000 | ~$86.1M | ~57% | ~ +$13M |

Revenue uses the bottom-up SOM ramp (§2.2) at blended ~$2,050 (plus a thin, high-margin cradle-accessory tail on the Core installed base). The business is burn-heavy in Year 1 (development), crosses toward operating breakeven around Year 3 as volume amortizes tooling and fixed cost, and generates cash on a premium-margin hardware line thereafter. A Series A (est. $15–25M) between Years 2–3 would fund the volume ramp and working capital.

## 9. Risks & mitigations

| Risk | Type | Mitigation |
|------|------|-----------|
| Triptych fold / lift reliability under travel abuse | Technical | Over-margined cycle-life targets (50k hinge / 20k lift), serviceable strut modules, ORT, shock-isolated cradles |
| Thin-film OLED cost & supply | Supply | Dual-source panels; uniform 14" panel to maximize volume leverage; DSC headroom lets a cheaper panel spec still hit refresh targets |
| Weight creep past 7.9 kg (Dock) / 8.2 kg (Core, case only) | Technical | Weight budget owned line-by-line (§4.4); aluminum-frame targets; battery sized to 99 Wh not larger |
| Studio-loaded Core (~10.9 kg) exceeds strict 10 kg cabin limits | Market/regulatory | Publish per-carrier guidance; steer strict-limit travelers to a Mac-mini-loaded Core (~8.9 kg); position the Mac Studio as a checked-transport / at-destination desktop |
| Cradle fit/quality across many third-party machines | Technical | Ship pre-validated cradles for popular Macs; parametric STL + a fit-tolerance guide for the long tail; blind-mate float absorbs print variation |
| Airline battery / carry-on compliance | Market/regulatory | Each pack < 100 Wh; certify UN 38.3; document carry-on legality; publish carrier-policy guidance |
| Runtime under-delivers vs. "4–6 h" | Technical | Honest split: internal pack runs the case's displays+AV (~4.5 h), host charges on AC — no over-promise |
| Price resistance at $1,899 / $2,199 | Market | Segment on ROI (billable travelers), lead with the two-minute deploy demo, enterprise fleet bundles; Core's BYO-compute story keeps it only $300 over Dock |
| Fast-follower clones of the concept | Competitive | Execution-quality moat (tolerance-critical mechanisms), the open printed-cradle ecosystem, first-mover brand + category ownership, closely-held firmware/deploy tuning |
| Contract-manufacturer execution (mechatronics + battery + display) | Supply | Select a CM with all three competencies; staged EVT/DVT/PVT; second-source key mechanisms; tariff-hedged geography |
| Category education (a new product class) | Market | The product demos itself; crowdfund + travel-retail live deploys; content around the "deployable office" idea |
