Noise/Vibration Control TRIZ Cases

Coaxial adaptor links motor shaft to output gear, eliminating intermediate gears to reduce noise and extend motor lifespan.

A brake tie bar connects the pad to the piston while allowing independent rotation.

A brake caliper assembly integrates a mounting rib and vibration-proof member to secure the styling cover.

An arc-shaped brake pad aligns lateral sides with radial lines to optimize pressure distribution across the friction surface.

A brake piston cap pivots relative to the body to accommodate uneven wear.

A metallic shim with a sinusoidal cross-section eliminates squeal without viscoelastic layers that degrade under heat.

Slidably contacting hooks on a laminated shim reduce frictional resistance between the pressing member side shim and backing plate, suppressing brake noise.

A brake pad hold down device uses spring projections to exert retaining force on the pad and biasing force against the caliper.

Nested housing modules with damping components isolate vibration and noise from gear collisions.

Segmented elastic loops and holding portions stabilize lug pieces within guide grooves, suppressing rattling noise during vibration.

An elastic pad spring stabilizes brake pad attitudes to prevent squeal while protecting torque surfaces from rust without adding assembly complexity.

Segmented springs isolate bearing limbs from curved sliding limbs, eliminating geometric inconsistencies that cause noise during braking.

Spring reaction bars apply outward force to suppress pad kick and vibration, reducing wear on commercial vehicle disc brake components.
