Regulations
Business Context
Reducing sheet metal, coatings, adhesives, sealants, lubricants, and other production materials lowers cost, waste, and environmental impact. Excessive reduction, however, can narrow process margins and increase defects when material quantity approaches the minimum required for reliable performance.
Automotive TRIZ Resolution
Automotive TRIZ replaces uniform material margins with controlled application according to actual functional demand. Precision dispensing, variable thickness, localized reinforcement, process measurement, and closed-loop adjustment can reduce average material consumption while ensuring that critical locations continue to receive the required quantity.
Applicable TRIZ Principles
Principle 3 – Local Quality varies material quantity according to local functional requirements.
Principle 15 – Dynamics adjusts material application to actual process conditions.
Principle 23 – Feedback measures application performance and corrects deviations before defects occur.
Expected Outcome
Lower material consumption
Maintained product quality
Reduced production waste
Improved process capability
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Material reduction immediately increases defects.
Uniform application quantities are based on worst-case requirements.
Large process margins compensate for poor measurement capability.
Material usage varies significantly without corresponding product requirements.
Waste-reduction programs repeatedly encounter quality resistance.
Monitoring these indicators helps determine where precision control can replace excessive material margins.
