Business Context
Reducing scrap, excess material, purge volumes, process fluids, packaging, and other production waste improves cost and environmental performance. However, some processes use excess material or conservative operating margins to maintain stability. Aggressive waste reduction can therefore expose process variability and increase defects or interruptions.
Automotive TRIZ Resolution
Rather than removing protective margins uniformly, Automotive TRIZ identifies why the excess resource is required. Better process control, localized material application, closed-loop adjustment, improved measurement, and condition-based dosing can reduce waste while preserving the process conditions necessary for stable production.
Applicable TRIZ Principles
Principle 3 – Local Quality applies materials or resources only where and in the quantity required.
Principle 15 – Dynamics adjusts process inputs according to actual operating conditions.
Principle 23 – Feedback controls resource use through real-time process information.
Expected Outcome
Reduced production waste
Maintained process stability
Lower material consumption
Improved process control
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Scrap increases when material allowances are reduced.
Processes depend on excessive input quantities for stability.
Waste-reduction initiatives increase production variability.
Fixed dosing remains unchanged despite changing process conditions.
Large safety margins compensate for limited process information.
Monitoring these indicators helps determine whether better control can replace excessive material or process margins.
