Wireless Air-Compression Recovery Boots Control System
A representative cordless recovery-boot architecture for multi-chamber pressure sequencing, local display, battery operation, bilateral wireless coordination, and independent fail-safe release.
Project context
A representative engineering program
A representative cordless recovery-boot architecture for multi-chamber pressure sequencing, local display, battery operation, bilateral wireless coordination, and independent fail-safe release.
System architecture
How the electronics are organized
The pictured HMI board manages LCD, keys, and wireless communication; a separate local power board is expected to drive the pump and valves from calibrated pressure feedback, with each boot enforcing its own absolute limits.
Engineering risks to close
What must be resolved before release
- Maintain calibrated multi-chamber pressure despite sensor drift, leakage, and battery sag.
- Coordinate two boots without making real-time safety depend on the radio link.
- Release pressure after valve sticking, blocked exhaust, firmware failure, or depleted battery.
Validation plan
Evidence expected before production
- Calibrate pressure zero and span, then record every chamber's rise, hold, leak, and release behavior.
- Inject sensor drift, valve sticking, blocked tubing, wireless loss, low battery, and power interruption.
- Run pump thermal, valve-cycle, tube-flex, weak-signal, and left-right pressure-consistency endurance.
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: Calibrate pressure zero and span, then record every chamber's rise, hold, leak, and release behavior.
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
