Manufacturing feasibility assessment
5. Verdict
Replace collision-free guarantee with advisory alerts and add redundant radar/ultrasonic sensing; commodity hardware can meet BOM targets, so start with a 50-unit pilot and garage trials.

7. Bill of materials
| Item | 100 | 1,000 | 10,000 |
|---|---|---|---|
| 7.1 Class 1 IR ToF camera module with illuminator | $38–52 | $26–36 | $19–28 |
| 7.2 Application processor, memory, and power-management PCB | $22–30 | $15–21 | $11–16 |
| 7.3 Optical window, lens bezel, and calibration features | $8–12 | $5–8 | $3.50–6 |
| 7.4 Molded ceiling enclosure, mount, and fasteners | $14–20 | $8–12 | $5–8 |
| 7.5 Speaker, LEDs, buttons, and wiring | $5–8 | $3.50–5.50 | $2.50–4 |
| 7.6 Listed external AC/DC adapter and low-voltage cable | $11–16 | $8–11 | $6–9 |
| 7.7 Final assembly, optical calibration, test, and packaging | $16–23 | $10–15 | $7–11 |
| 7.8 Total ex-factory BOM and conversion | $114–161 | $75.50–108.50 | $54–82 |
At 10,000 units, tooling adds about $9.50–18.50 per unit, or 3.8–7.4% of the $250 entry retail. The $54–82 10k BOM is 22–33% of entry retail, leaving room for channel, warranty, certification, and margin.
8. Gates to clear
8.1 [DFM]
A single fixed camera position will not reliably cover different ceiling heights, vehicle sizes, garage depths, and reflective or dark obstacles.
Path: Define a 2.5–6 m installation envelope; use an adjustable mount; run guided vehicle/garage calibration; validate optical coverage with a contract manufacturer using calibrated end-of-line fixtures.
8.2 [Certification]
Global sale cannot use one universal approval. IR emission, mains power, EMC, materials, and any optional radio require regional compliance.
Path: Launch wired regional SKUs: CE EMC/LVD/RoHS and IEC 62471 or IEC 60825-1 Class 1 assessment for EU; FCC Part 15 plus UL/ETL-listed adapter for US; add UKCA, RCM, and other local marks by launch country. Treat Wi-Fi/Bluetooth as a later RED/FCC/ISED radio variant.
8.3 [Tooling]
Optical alignment and calibration fixtures are material upfront costs; low-volume production would push cost above the intended retail structure.
Path: Build 100-unit EVT/DVT units in machined housings, freeze the sensor and mount geometry, then release injection tooling only after installation trials support a 10,000-unit forecast or committed channel order.
9. Prototype sequence
- 9.1Build a bench prototype using an off-the-shelf Class 1 ToF camera, compute board, speaker, and adjustable ceiling rig.Confirms sensing range, glare behavior, obstacle detection, and alarm timing before custom electronics.
- 9.2Collect parking data across representative garages, vehicle sizes, ceiling heights, lighting conditions, and common stored objects.Defines the supported installation envelope and exposes false alarm or missed-object conditions.
- 9.3Develop guided setup for vehicle envelope, parking endpoint, obstacle map, sensor aiming, and lens-obstruction fault checks.This is the required product change that makes variable home-garage installation manufacturable and supportable.
- 9.4Run a 20–40 home pilot with assistance-only labeling and documented edge-case reporting.Validates user behavior, alert usability, mount stability, dust effects, and calibration retention.
- 9.5Complete DVT with production-intent optics, enclosure, listed adapter, calibration fixtures, and regional pre-compliance testing.Reduces certification and yield risk before committing $95,000–185,000 to production tooling.
