In regulated medical device engineering, a seemingly routine component substitution can silently trigger months of bench testing, clinical amendments, and multimillion-dollar regulatory supplements. PMX OS Decision Simulator empowers cross-functional teams to stress-test decisions across 7 critical dimensions before formal Engineering Change Order (ECO) execution.
Execute the PMX OS graph traversal engine to trace how replacing temperature sensor S-18 with digital transducer S-22 propagates across hardware, firmware, risk controls, and regulatory filings.
Evaluating Baseline Sensor S-18 (MicroSens analog thermistor) versus Proposed Sensor S-22 (OmniSem digital I2C transducer) across the 7 dimensions of medical device lifecycle feasibility.
| Dimension | Baseline: Sensor S-18 (MicroSens Analog) | Proposed: Sensor S-22 (OmniSem Digital) | Impact |
|---|---|---|---|
| 1. Cost Profile | Unit BOM: $14.20. High assembly overhead due to external analog signal conditioning circuit and precision op-amp. | Unit BOM: $11.85. Saves $2.35/unit. One-time non-recurring engineering (NRE) test re-verification cost of $185,000. | +Net ROI |
| 2. Timeline & Supply | Lead time extended to 34 weeks due to sole-source raw material delays at Supplier Y. Critical inventory depletion risk in Q4 2026. | Lead time: 6 weeks from Supplier Alpha (OmniSem, dual-fab sourcing). 16-week re-verification & submission cycle. | Saves 28w |
| 3. ISO 14971 Risk Profile | Prone to analog temperature resistance drift (RSK-0051) and thermal burn injury (RSK-0044) if lot sintering deviates (+3.2%). | Integrated digital ADC eliminates analog drift. Introduces I2C digital bus timeout hazard (RSK-0092), mitigated via RTOS watchdog. | Net Safe |
| 4. Regulatory Filing | Cleared under FDA 510(k) K240982 and EU MDR Technical Documentation Rev 3. Fully authorized commercial predicate. | Determined as FDA Special 510(k) (30-day review) under K97-1 flowchart. EU MDR Annex II Section 4.2 Technical File supplement. | Supp Req |
| 5. Verification Burden | All historical verification protocols executed and locked. Baseline evidence EV-0183-A verified in 2024. | Invalidates 5 protocols: V-0183 (36h thermal stress), V-0201 (EMC radiated immunity for I2C clock), V-0204 (drop test), V-0215 (aging). | 5 Protocols |
| 6. Clinical Validation | Validated in 240-patient clinical investigation CS-088 for skin integrity and temperature measurement accuracy. | Zero human trials required. Sensor housing polycarbonate remains identical; clinical team files bench equivalence addendum. | Zero Trials |
| 7. Cybersecurity Surface | Zero digital addressable registers. Immunity to digital bus command injection; vulnerable only to ADC line noise. | Exposes I2C digital registers over internal serial bus. Requires cryptographic frame signing under SEC-CTRL-19. | SEC Control |
