Manufacturing feasibility assessment
5. Verdict
Limit it to clinician-fitted, low-torque gait assistance with fail-safe release and one indication; pursue ISO 13485/14971 and regional clearance, starting with a 50-user pilot.

7. Bill of materials
| Item | 100 | 1,000 | 10,000 |
|---|---|---|---|
| 7.1 Waist-mounted actuator modules and gearboxes | $700–1,000 | $420–650 | $270–420 |
| 7.2 Battery pack, BMS, charger, and power harness | $260–380 | $170–260 | $115–180 |
| 7.3 Sensors, control PCB, safety electronics, and firmware loading | $250–390 | $150–245 | $95–160 |
| 7.4 Bowden cables, anchors, quick-release hardware, and covers | $170–280 | $105–175 | $70–115 |
| 7.5 Technical textile harness, pads, closures, and washable liners | $230–360 | $145–235 | $90–150 |
| 7.6 Assembly, calibration, end-of-line test, and packaging | $260–420 | $155–260 | $100–170 |
| 7.7 Estimated landed manufacturing BOM | $1,870–2,830 | $1,145–1,825 | $740–1,195 |
At 10,000 units, tooling adds about $45–110 per unit, or roughly 0.5–3.7% of the $3,000–10,000 retail range. The 10k BOM remains below 40% of the $3,000 entry retail, but only near the upper end of the BOM range.
8. Gates to clear
8.1 [DFM]
A universal soft exoskeleton for frail users produces inconsistent fit, cable routing, pressure points, and assistance geometry.
Path: Restrict Gen 1 to a single body region and assistance task, use 3–5 validated size bands, then run wear trials with a medical-textile OEM and contract manufacturer.
8.2 [Certification]
Global therapeutic, fall-prevention, or rehabilitation claims substantially increase evidence, safety, and regulatory scope.
Path: Launch by region: EU CE marking under MDR with ISO 13485, ISO 14971, IEC 62366-1 and IEC 60601-1/-1-2 assessment; pursue US FDA pathway separately after predicate and intended-use review.
8.3 [Tooling]
The $3,000 retail floor cannot support low-volume production, broad global certification, and clinician service if BOM stays near the 100-unit estimate.
Path: Begin with clinic or distributor deployment at $6,000–10,000 retail, use contract manufacturing at 500–1,000 units, and fund dedicated tooling only after demand supports 10,000-unit annual volume.
9. Prototype sequence
- 9.1Freeze a single indication, body region, user weight range, and clinic-supervised use model.This converts an overly broad global device concept into testable safety, fit, and regulatory requirements.
- 9.2Build 15–30 adjustable alpha units using off-the-shelf motors, batteries, sensors, and sewn textile harnesses.Early units should expose comfort, donning, cable-routing, and caregiver workflow failures before custom tooling.
- 9.3Run supervised fit, mobility, pressure, and fault-response studies with geriatric users and clinicians.Evidence is needed to set assistance limits, size bands, quick-release requirements, and realistic intended-use claims.
- 9.4Complete design verification with production-intent electronics, battery protection, washable liners, and end-of-line calibration.This establishes the design-history and risk-management evidence needed before formal regulatory testing.
- 9.5Pilot 100–300 units through an ISO 13485-capable medical-device contract manufacturer and regional regulatory sequence.The pilot validates yield, service burden, landed cost, and certification readiness before committing production tooling.
