Noise/Vibration Control TRIZ Cases
- Rail Brake Disc Coupling With Thermal Isolation and Torsional Damping
An intermediate sheet limits brake heat into the wheel while compliant disc coupling cuts torsional vibration and wheel damage in rail running gear.
- Brake Disc Rigidity Layout for Squeal and Vibration Reduction
Alternating rigid and compliant brake disc regions with prime-spaced connectors suppress circumferential waves, cutting squeal and improving cooling.
- Brake Pad Counterweight Locking to Prevent Rotation Under Vibration
A grooved support plate locks brake pad counterweight protrusions against rotation, cutting noise, easing assembly, and lowering production cost.
- Anti-Squeal Shim Structure for Direct Brake Pad Force Sensing
A compressible elastomer shim turns brake pad load into resistance changes, enabling direct, simple pressure sensing in brake systems.
- Laser-Textured Brake Carrier Disc for Stable Pad Bonding
Laser-made surface depressions strengthen friction lining adhesion at high speed while damping means help reduce brake noise and emissions.
- Brake Disc Elastic Coupling to Reduce Rattling and Axial Clearance
Elastic elements preload the braking band against the bell to cut rattling, limit axial and circumferential impacts, and keep the disc compact.
- Disc Brake Pad Clip Insertion Structure for Light-Braking Stability
A radially outward pad clip stabilizes disc brake pad posture during light braking, reducing noise while preserving pad area.
- Additive-Manufactured Torque Bar for Stiffness and Vibration Damping
Additive manufacturing enables torque bars with varied cross-sections, voids, and webs to improve stiffness, damping, and dynamic stability.
- Fishing Reel Brake Layout for Backlash Control and Low Pad Wear
A fixed and movable magnetic brake layout adjusts spool braking by speed to limit backlash, pad wear, noise, and casting loss.
- Aircraft Brake Disc Interfaces for Low-Friction Vibration Attenuation
Low-friction bracket interfaces in aircraft wheel brakes suppress braking vibration below 20 g without adding weight or slowing control response.
- Brake Disc Bell and Band Preload to Eliminate Rattle
Elastic elements preload the braking band and bell to minimize axial and circumferential clearances, cutting brake disc rattle and impacts.
- Composite Brake Friction Assembly for Lower Weight and Reliability
Co-moulded phenolic resin and reinforcing fibers cut brake calliper weight while preserving braking reliability, strength, and heat resistance.
- Aircraft Brake Centering Ring With Alternating Bearing Zones
Alternating bearing zones and flexible ligaments let an aircraft brake centering ring absorb vibration, install easily, and avoid permanent deformation.
- Brake Disc Braking Band Recess Layout for Squeal Reduction
Radial outer-edge recesses in the braking band suppress high-frequency brake squeal by changing damping, stiffness, and pressure distribution.
- Hybrid Torque Bar Structure for Wear and Material Waste
Combining machined and additive-built torque bar sections cuts material waste while improving wear resistance and structural integrity.
- Heavy Vehicle Brake Temperature Monitoring for Hot Runner Detection
Brake pad temperature comparison detects early hot runner brake lockup in heavy vehicles and triggers CAN-bus alarms before overheating damage.
- Friction-Damped Inserts for Resonance-Prone Structural Components
A non-flat perforated insert adds friction damping to highly stressed components, cutting resonance noise while preserving bonding strength.
