Axle Suspensions TRIZ Cases
- Shock Absorber Spring Seat Slider for Tool-Free Height Adjustment
A snap-fit slider locks spring seat rotation on the outer tube, enabling precise tool-free vehicle height adjustment without unintended shifts.
- Vehicle Suspension Tune Switching for Terrain Adaptation
Predefined suspension tunes selected by a manual switch let the controller match terrain conditions without complex continuous damper adjustment.
- Manual Suspension Tune Switching for Changing Terrain Conditions
A manual switch and active valve system let riders change suspension tunes on the fly to match terrain without compromising damper performance.
- Rotationally Molded Bicycle Wheel Structure to Reduce Warping
A one-piece hollow thermoplastic wheel uses rotational moulding and variable wall thickness to improve strength, dimensional accuracy, and recyclability.
- Rear Suspension Damping Control From Front Wheel Obstacle Force
Front wheel obstacle force is converted with bank angle and acceleration to control rear suspension damping without a rear stroke sensor.
- Bicycle Suspension Control Using Ride-State Events
Sensors trigger timed suspension-setting events to match ride state, improving bicycle suspension response while reducing battery drain.
- Manual Suspension Tune Selection for Stable Terrain Damping
An active valve system and manual switch let riders change predefined suspension tunes by terrain while preserving stable damper operation.
- Variable Shock Absorber Control for Faster Self-Pumping Ride Height
During self-pumping ride height increase, damping is weakened only in the spring-pushing phase to preserve comfort and steering stability.
- Articulated Swingarm Suspension for Constant Anti-Squat
A four-link swingarm suspension keeps anti-squat nearly constant through travel, reducing chain interference and preserving grip and damping.
- Self-Pumping Spring Preload Assembly for Dynamic Ride Height
A valve-controlled self-pumping preload assembly adjusts suspension ride height and damping under changing vehicle loads without external pumps.
- Active Suspension Damping for Gravel Road Roughness Detection
Frequency-based terrain detection distinguishes gravel from true rough roads, preventing false damping changes and preserving ride comfort.
- Bicycle Suspension Control Using Ride-State Events to Cut Power Use
Sensors and a control unit divide riding into timed events, adapting bicycle suspension automatically while reducing battery drain.
