Liquid Based Dampers TRIZ Cases

See how a coupling-activated additional braking device enhances viscous damping force at high s

A speed-activated auxiliary brake boosts damping force at higher motion speeds while keeping low-speed friction and seal-related drag low.

A sub-cylinder hydraulic lock raises compression-side pressure near stroke end to suppress bottoming and rough-road impact without stiffer springs.

A follow-and-stop engagement mechanism adds braking on seat-back return, preventing hard seat cushion collisions while easing lift load.

Integrated external fluid pathways and valves in a single shock body cut assembly cost, fit tight spaces, and improve damping and heat dissipation.

Integrated raised fins on a monolithic shock absorber cylinder improve hydraulic fluid heat transfer while reducing welded parts and assembly complexity.

One-way passages in the upper cap feed fluid from the reserve to rebound reservoir, reducing pressure imbalance, hysteresis, and negative rebound pressure.

Fluid-filled shock absorbers replace bulky helmet padding to cut weight, improve impact attenuation, and reduce pressure points.

Fluid-filled tanks tuned to tower natural frequencies move out of phase to cut cross-wind vibration and reduce metal fatigue.

Cross-connected shock absorbers redirect fluid between paired chambers to limit landing opposing force while preserving roll damping against ground resonance.

Fluid in tuned tower tanks moves out of phase at natural frequencies, damping cross-wind vibration and reducing metal fatigue.

Two-stage telescopic auxiliary actuator positions the bogie beam for stowing, resolving hydraulic complexity trade-offs via multi-function integration.

A positioning pin constrains the rack gear to prevent separation from the damper gear, resolving reliability issues under high force.

A height-adjustable spring arrangement uses a guide piston rod to adjust preload while maintaining constant negative spring deflection.
