Wound Springs TRIZ Cases
- Protected Spring-Assist Trailer Ramp Hinge for Damage Resistance
Built-in coil springs nested inside the trailer ramp hinge and bumper protect pivot parts from damage while keeping ramp movement smooth.
- Variable-Turn Wave Spring Alignment for Stable Load Distribution
Aligned active and non-active turns improve wave spring load distribution while reducing torsional loads and friction during component preloading.
- Twin-Spring Coupling Assembly for Low-Friction Alignment
Rollers and pin-guided coupling keep twin springs aligned while cutting sliding friction and avoiding guide locking.
- End-Coil Spring Geometry to Suppress Lateral Force
Bent end-coil regions keep the active coil count stable during compression, cutting lateral force, friction, and wear.
- Variable-Damping Shock Absorber With External Oil Discharge
Oil is routed through shaft passages and regulating bolts to prevent heat buildup in the damping chamber and keep shock absorption stable.
- Suspension Strut Spring Ring Assembly to Prevent Twisting
An integral spring-support ring with rib-and-groove elastic fitting stops ring twisting and keeps the strut retained after spring breakage.
- Spiral Spring Coupling for Wider Shaft Rotation and Strength
A conformal spring inner end tightens onto a noncircular shaft to expand rotation, strengthen coupling, and free hollow-shaft space.
- Aligned Variable-Turn Wave Springs for Stable Component Preload
Aligned active and non-active wave spring turns stabilize preload, reduce torsional vibration, and improve load distribution in components.
