System architecture
How the electronics are organized
An MCU and antenna region coordinate motor drivers and, where the product SKU includes light sources, calibrated constant-current zones; temperature, current, and contact or shielding inputs gate the session.
Engineering risks to close
What must be resolved before release
- Protect a large open-ring board and its interconnects from bending and drop stress.
- Control motor noise, hair-entanglement risk, and real-wear wireless attenuation.
- If light output is fitted, maintain zone uniformity, dose limits, and contact interlocks.
Validation plan
Evidence expected before production
- Run mechanical stall, hair-interaction, vibration, cleaning, sweat, and enclosure-flex tests.
- Measure radio performance with the device worn and the motor active.
- For light-enabled SKUs, calibrate each zone and verify optical output, temperature, timing, and interlock faults.
Decision-ready evidence packet
What a comparable RFQ should define
This checklist turns the technical story into reviewable inputs and release records. It describes what buyers and manufacturers should agree—not a claim that every listed record applies to every build.
Design baseline
Released schematic or block diagram, interface table, power states, critical constraints, and revision owner.
Manufacturing release
Gerber or ODB++, stack-up, centroid data, assembly drawings, approved DFM dispositions, and panel assumptions.
Material control
Released BOM revision, manufacturer part numbers, AVL or alternate rules, no-substitute lines, MSL handling, and exception approvals.
Validation record
Test method, acceptance criteria, sample or serial identity, measured result fields, and disposition. Example scope: Run mechanical stall, hair-interaction, vibration, cleaning, sweat, and enclosure-flex tests.
Production release
First-article status plus the agreed SPI, AOI, X-ray, ICT, FCT, programming, rework, OQA, labeling, and packing records.
Project-specific fields, retention periods, sampling rules, measured limits, and customer approvals are confirmed during RFQ and protected under the applicable confidentiality agreement.
Development and production controls
Manufacturing scope represented here
- Wearable motor-control integration.
- Optional zoned constant-current outputs.
- Wireless session and safety-state management.
