Business Context
High-precision automotive processes require accurate positioning, force, temperature, alignment, dimensional control, or tool behavior. As equipment tolerances become tighter, relatively small amounts of wear, contamination, drift, or misalignment can affect process capability and increase maintenance sensitivity.
Automotive TRIZ Resolution
Automotive TRIZ prevents precision from depending entirely on maintaining every mechanical element within extremely narrow tolerances. Automatic calibration, closed-loop compensation, reference measurements, modular precision elements, and environmental control can preserve output accuracy despite acceptable equipment variation.
Applicable TRIZ Principles
Principle 3 – Local Quality concentrates precision requirements in the elements that directly determine process output.
Principle 23 – Feedback detects and compensates for developing process deviation.
Principle 35 – Parameter Changes adjusts operating parameters to maintain required accuracy as equipment condition changes.
Expected Outcome
Maintained process precision
Lower maintenance sensitivity
Longer stable operating periods
Reduced adjustment requirements
Decision Indicators
Early indicators that this contradiction is limiting equipment performance include:
Minor wear causes immediate quality deterioration.
Equipment requires frequent manual calibration.
Precision depends on maintaining large assemblies within extremely tight tolerances.
Process capability declines well before functional equipment failure.
Maintenance effort increases sharply as quality tolerances tighten.
Monitoring these indicators helps determine where precision can be maintained through measurement and compensation rather than mechanical perfection alone.
