Springs TRIZ Cases
- Gas Spring Brake Throttling for Controlled Furniture Post Motion
A throttle inside the gas pressure spring limits furniture post adjustment speed to prevent sudden lifting or dropping when unlocked.
- Drum Balancer Control for Washing Machine Spin Imbalance
Movable ring balancers counter uneven laundry loads and adapt as rinsing changes the imbalance, cutting spin-cycle vibration and noise.
- Shock Absorber Bracket Assembly for Transverse Load Stability
A two-piece bracket with nested support arms reinforces the shock absorber shaft to resist transverse loads and prevent rupture.
- Fluid Damper Valve Support Structure to Prevent Floating Wear
A receiving part and segmented valve support restrain valve-body floating, reduce wear, and keep stable closing attitude in a fluid damper.
- Washer Tub Suspension Layout for Larger Drum Capacity
A decoupled tub and drum support layout buffers vibration, enabling a larger drum within the same washer cabinet size.
- Gas Spring Trigger Housing for Low-Force Release Control
A dual-orientation housing and internal lever-cable linkage cut gas spring trigger force while improving release control and installation flexibility.
- Integrated Friction-Viscous Damper for Speed-Dependent Braking
A coupled friction and viscous damper delivers speed-dependent braking with low empty friction in a compact structure for movable components.
- Washing Machine Suspension With Dual Friction Vibration Attenuation
Dual friction units adapt damping across normal and excessive tub vibration while supporting self-lubrication to reduce wear and noise.
- Expansion Valve Contact Surface for Low-Opening Vibration Suppression
A shaped actuating-bar contact surface increases spring deformation near valve closing to suppress vibration and abnormal noise.
- Washer Outer Tub Shock Absorber for Compact Vibration Damping
A rod-guided elastic and friction damper absorbs normal and excessive tub vibration, reducing washer height while preventing tub collision.
- Tilt-Head Mixer Damper Mechanism for Smooth Closure
A swing-body piston damper slows the mixer head only during final closing, reducing jarring impact and rebound without limiting opening motion.
- Furniture Hinge Damper With Variable Flow Path Pressure Control
A pressure-adjusted flow path lets one furniture hinge damper keep door opening and closing speed stable across different door sizes and weights.
- Pneumatic Wash Tub Damping With Self-Regulating Valve Control
A sealed pneumatic cylinder with one-way valves varies damping by vibration amplitude, stabilizing washing machine tubs without external feedback.
- Expandable-Lining Friction Damper for Washing Machine Oscillations
An expandable body in the friction lining helps a washing machine damper absorb unbalance oscillations while improving heat dissipation and lowering stress.
- Vehicle Seat Gas Spring Thread Mounting for Play-Free Adjustment
Different thread parameters and elastic deformation create a play-free gas spring mount that reduces seat adjustment noise and vibration.
- Spiral Damping Shaft With Variable Oil Clearance for Toilet Covers
A spiral shaft and guide bush vary oil clearance during rotation, giving toilet covers fast start and soft-close damping with simpler structure.
- Furniture Damper Freewheel Locking for Immediate Damping
A freewheel locking damper removes complex valves, enables immediate damping on actuation, and lowers tolerance and manufacturing demands.
- Corrugated Composite Suspension Spring for NVH and Mass Production
A hollow corrugated preform with 3D braiding and pultrusion raises spring constant, improves NVH, and supports lower-cost mass production.
- Furniture Damper Using Particle-Filled Shear-Thinning Medium
Packed solid particles in a viscous liquid cut damper leakage while maintaining stable furniture fitting damping across temperature changes.
- Telescopic Damper Sensor Module for Easy Washer Assembly
A slip-on coil sensor module for telescopic washer dampers cuts mounting complexity, assembly time, and replacement effort.
- Laundry Drum Suspension Assembly for Directional Vibration Isolation
A directionally stiff suspension isolates drum vibration from the tub, enabling a larger washer drum without increasing cabinet size.
- Rolled Tubular Friction Damper for Stable, Low-Noise Washers
A rolled sheet-metal piston rod replaces semi-cylinders and a coupling ring to cut washer damper cost, noise, and heat buildup.
- MR Fluid Damper Sealing Structure for Stable Washer Vibration Control
Sealing members and resin-fixed yokes keep MR fluid from leaking despite assembly variation, preserving stable washer damping force.
