Skate-Boards TRIZ Cases

An asymmetric wheel layout with a motorized front swivel wheel and passive rear wheel improves board stability while preserving tight turns and drifting.

A circulating belt over multiple rollers helps sports gear travel on grass or stony ground with steadier motion and fewer falls.

Dual powered skates use calibration, remote control, and posture sensing to keep motor speeds synchronized while improving turning and braking.

An internal pivot and elastic strip let the rear wheel absorb multidirectional impacts, improving roller ski stability and snow-like feel.

An external linkage frame frees housing space in retractable shoe wheels, lowering sole height and integrating the power supply for better stability.

Inclined pivot hubs replace complex spring steering, giving a weight-shift skateboard smoother control and better handling on rough surfaces.

A foot dolly with caster-supported pegs and a mid pivot adds seated riding, stabilizes feet, and reduces fatigue on motorized skateboards.

A motor-driven skate paired with a non-powered skate improves support, speed, and comfort while reducing manual propulsion effort.

A spring-loaded pin locks into wheel spoke holes to immobilize roller skates when a secure stop is needed.

Rotating compression triangles and shock absorbers let a wheeled ski absorb impacts and clear obstacles on rough snowless terrain.

Mechanical stops lock the calf support at a set forward angle, reducing balance effort, fatigue, and discomfort during braking or acceleration.
