Equipment Protection vs Fault Detection
Use consequence-based criticality assessment to direct redundancy investment only where failure impact on life-safety or operations is highest.

Regulations
Business Context
Protective covers, sealed housings, isolation systems, and enclosed components shield automotive production equipment from contamination and damage. These protections can also conceal leaks, wear, overheating, loose connections, or developing mechanical problems from routine observation.
Automotive TRIZ Resolution
Automotive TRIZ transfers condition information across the protective boundary instead of weakening the protection. External indicators, temperature sensing, vibration monitoring, inspection windows, diagnostic ports, and internal self-monitoring can reveal degradation while equipment remains protected.
Applicable TRIZ Principles
Principle 24 – Intermediary transfers condition information through the protective boundary.
Principle 23 – Feedback provides evidence of internal equipment condition.
Principle 28 – Mechanics Substitution replaces direct physical inspection with suitable sensing technologies.
Expected Outcome
Maintained equipment protection
Earlier fault detection
Reduced unnecessary disassembly
Faster maintenance diagnosis
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Failures remain hidden until protective structures are removed.
Routine inspection requires opening sealed equipment.
Leaks or overheating are discovered only after secondary damage occurs.
Protective covers significantly increase diagnostic time.
Maintenance teams remove protection primarily to check equipment condition.
Monitoring these indicators helps identify where condition information can be made accessible without exposing protected components.
