Business Context
Increasing machine speed can raise automotive production throughput without adding equipment. Higher speeds, however, increase acceleration forces, friction, vibration, impact loading, heat generation, and mechanical cycling, potentially accelerating wear and reducing reliability.
Automotive TRIZ Resolution
Automotive TRIZ focuses on reducing damaging interactions rather than restricting productive motion uniformly. Optimized motion profiles, low-friction interfaces, improved balancing, localized damping, and high-speed operation only during productive portions of the cycle can increase output without proportionally increasing mechanical stress.
Applicable TRIZ Principles
Principle 15 – Dynamics varies equipment speed according to the requirements of each cycle phase.
Principle 19 – Periodic Action applies maximum speed only where it contributes useful throughput.
Principle 35 – Parameter Changes modifies motion, friction, or operating characteristics to reduce wear.
Expected Outcome
Higher production throughput
Reduced mechanical wear
Longer component life
Improved equipment reliability
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Small speed increases cause significant maintenance growth.
Failures concentrate in high-acceleration portions of machine cycles.
Equipment operates at maximum speed during nonproductive motion.
Vibration increases sharply with production rate.
Throughput targets repeatedly conflict with component-life expectations.
Monitoring these indicators helps identify where machine motion can be optimized rather than globally slowed.
