Regulations
Business Context
Automotive tooling must achieve accurate positioning and repeatable process conditions to maintain dimensional and assembly quality. Precise setup often requires alignment, measurement, adjustment, and verification, which can extend changeover time in model-mix production.
Automotive TRIZ Resolution
Automotive TRIZ transfers precision from repeated manual adjustment into the tooling interface. Kinematic locating features, standardized connections, preset tooling, automatic calibration, identification systems, and error-proofed mounting can establish correct positioning as part of the changeover itself.
Applicable TRIZ Principles
Principle 10 – Prior Action presets tooling before installation.
Principle 13 – The Other Way Round makes the interface establish alignment instead of requiring alignment after installation.
Principle 23 – Feedback automatically confirms correct tooling position and configuration.
Expected Outcome
Faster equipment changeovers
Maintained tooling precision
Reduced setup variability
Lower dependence on manual adjustment
Decision Indicators
Early indicators that this contradiction is limiting production include:
Precision verification dominates changeover duration.
Tool installation requires repeated manual adjustment.
Setup quality varies significantly between technicians.
Faster changeovers increase dimensional defects.
Production flexibility is restricted by tooling setup requirements.
Monitoring these indicators helps identify where precision can be designed into the interface rather than recreated during every changeover.
