Resilient Suspensions TRIZ Cases

A continuous dropped axle tube carries wheel-drive generators outside the force path, boosting load capacity while cutting joints, weight, and volume.

A four-DOF active suspension with genetic H∞ tuning suppresses 0.1-0.5 Hz vertical and pitch vibrations to reduce motion sickness.

By shifting the vehicle body about the yaw axis during acceleration, the ECU raises tire-road force and improves traction.

Sensors and an actuator move a damper mass between fluid springs to counter road-induced suspension motion and improve ride comfort.

A press-fit steel eccentric mount protects a light-metal control arm from wear during camber and toe adjustment while maintaining stable force transfer.

A two-piece clevis and adapter mount enables quick spring changes with common tools while preserving the damper shaft joint.

By shifting the suspended mass during launch, the active suspension raises tire-road force and improves adhesion without relying on engine torque.

Pitch angle estimated from driving force, speed, and acceleration reveals front-rear axle load distribution without suspension sensors.

Sensors and active suspension actuators pre-position wheels and adjust ride height to soften pothole impacts and reduce suspension damage.

Multiple vehicle signals guide when to block pressurized air to the suspension air bag, cutting unnecessary air use and fuel consumption.

A pivoting rocking arm keeps motive and caster wheels in ground contact on uneven terrain, improving vehicle or robot stability without sensors.

Recessed bearings or wear pads support the leg tube top end to reduce wear, prevent tipping, and keep track-ground contact accurate.

Predictive suspension control adjusts front-rear ride height before gradient changes to improve visibility and reduce head toss.

Controlled rear axle steering and axle load redistribution cut trailer turning radius and swept path while maintaining traction in tight maneuvers.

A motorized suspension linkage changes cargo box height and angle to speed loading while lowering the trailer for transport and clearance.

By switching damping control in stable turning, this case improves circular turning behavior while maintaining roll suppression and wheel grip.

Using jerk-based hold conditions, this case keeps a vehicle air spring in high stiffness during dynamic motion to cut wear and avoid repeated switching.

Wheel-position sensing adjusts suspension damping to absorb obstacles on rough terrain while avoiding harsh ride quality on smooth roads.

Real-time comparison of cross-axle ride height sensor outputs speeds fault diagnosis, reduces unnecessary replacements, and supports suspension performance.

An optical structure reshapes luminance by viewing angle to cut driver-facing glare while preserving useful light output.

Combining air spring pressure, suspension height, and track width change improves vehicle load accuracy and avoids air spring damage.

Surface detection and independent wheel adjustment help a work vehicle maintain stability and braking on rough or sloped terrain.

A damper routed through the wheel guiding element preserves installation space while enabling longer damper length and a higher transmission ratio.

A reinforced side member raises upper arm mounting rigidity, limiting collision deformation while enabling lower hood height without drive shaft interference.
