Business Context
Predictive maintenance can identify developing failures before they interrupt automotive production, but improving prediction accuracy often requires additional sensors, data infrastructure, analytics, integration, and specialist support. Instrumenting every asset extensively can make predictive maintenance economically inefficient.
Automotive TRIZ Resolution
Automotive TRIZ concentrates monitoring resources according to failure criticality and diagnostic value. Existing controller data, electrical signals, process measurements, portable sensors, and shared monitoring infrastructure can provide useful condition information before dedicated instrumentation is added.
Applicable TRIZ Principles
Principle 3 – Local Quality applies advanced monitoring where failure consequences justify it.
Principle 6 – Universality reuses existing equipment and process data for condition monitoring.
Principle 23 – Feedback converts selected condition information into predictive maintenance decisions.
Expected Outcome
Improved failure prediction
Controlled monitoring investment
Better use of existing equipment data
Higher predictive maintenance value
Decision Indicators
Early indicators that this contradiction is limiting maintenance strategy include:
Predictive programs require extensive new instrumentation.
Low-criticality assets receive the same monitoring as production-critical equipment.
Existing machine data remains unused for maintenance decisions.
Monitoring costs exceed avoided failure losses for some asset classes.
Additional sensors generate data without improving maintenance action.
Monitoring these indicators helps identify where predictive resources should be concentrated according to operational value.
