Movement Coordination Devices TRIZ Cases

Rotatable support members accommodate various bicycle frame geometries, eliminating the need for multiple dedicated devices.

A sliding carriage exercise system uses guide rails and a resistance assembly to engage multiple muscle groups during movement.

Angled crank axes generate skewed foot motion planes to resolve the trade-off between simple parallel machine structures and limited, unbalanced leg engagement.

A lateral elliptical trainer uses a cable actuator to move carriages along guide rails for adjustable foot platform motion.

A rollback control mechanism applies friction to the treadmill belt upper portion to resist forward movement.

An AI exercise sequence generator creates personalized workout programs by communicating with smart gym equipment to determine machine availability.

Linear actuators adjust incline and lateral tilt angles to simulate varied terrain without overwhelming device complexity.

Nested tubular elements protect internal components from environmental pollution while magnetic connections allow adjustable obstacle height.
