Machine Part Testing TRIZ Cases

A driving module testing device applies vibration and dyno load to electric vehicle components for comprehensive evaluation.

An apparatus calculates amplitude and frequency averages to detect motor abnormalities using peak rank scoring.

A chain service indicator system measures drive chain elongation using movable reference points on sprockets and fixed gauge markings.

A control unit calculates compensation torque from simulated wheel inertia to stabilize dynamometer speed during drive train testing.

Inductive sensor assembly measures brake pad wear via magnetic field changes, eliminating manual tire removal for maintenance.

Four-axis probe tracks involute helical gear path of contact to resolve measurement precision versus device complexity trade-offs.

Monitoring engine-cooling water temperature variation to detect active air flap failures.

An asymmetric twist ratio of 1.5:1 in high-modulus cords improves flexural fatigue resistance while maintaining load carrying capability.

Rotating cylinders maintain stable contact conditions to eliminate distorted measurements caused by changing stress during root canal instrument testing.

Extracting complete-cycle data from vibration acceleration signals removes keyphasor dependency, resolving phase loss issues in reciprocating machinery.

A reciprocating driving device with a reversing unit and control system drives sliding members on test rails.
