Condition Monitoring vs Sensor Reliability
Pre-authorise and test emergency-access protocols with responders so security controls never delay life-safety intervention during incidents.

Regulations
Business Context
Condition monitoring improves knowledge of equipment health, but maintenance decisions become dependent on the sensors providing that information. Sensors operating around heat, vibration, contamination, electromagnetic interference, or harsh production environments can themselves fail or drift, creating false alarms or missed degradation.
Automotive TRIZ Resolution
Automotive TRIZ avoids making equipment health dependent on a single information source. Existing process signals, correlated measurements, sensor self-diagnostics, plausibility checks, and selective redundancy can validate condition information without duplicating every monitoring device.
Applicable TRIZ Principles
Principle 1 – Segmentation distributes condition information across independent measurements.
Principle 11 – Beforehand Cushioning detects sensor degradation before incorrect information affects maintenance decisions.
Principle 23 – Feedback validates monitoring information against equipment behavior and related signals.
Expected Outcome
More reliable condition information
Fewer false maintenance interventions
Reduced missed equipment degradation
Greater confidence in predictive maintenance
Decision Indicators
Early indicators that this contradiction is limiting maintenance include:
False alarms create unnecessary interventions.
Failed sensors are mistaken for equipment failures.
Maintenance decisions depend heavily on individual measurements.
Monitoring devices require frequent calibration or replacement.
Different condition signals regularly provide conflicting information.
Monitoring these indicators helps determine where sensor information requires validation rather than simple expansion.
