Movement Coordination Devices TRIZ Cases

An elongated aperture in the rigid support allows lateral speed bag movement while maintaining rebound rigidity to conserve kinetic energy.

A video playback system synchronizes terrain data with exercise equipment resistance and speed for immersive training.

An intermediary shield prevents contact with a spinning exercise bike wheel, resolving safety hazards while maintaining operational accessibility.

Lateral swing tracks allow users to apply force for variable trajectories, resolving fixed path limitations.

A dual-wheel exercising device enables smooth transitions between circular pedaling and elliptical footrest motion through synchronized mechanical linkages.

A crank system drives guide links and foot support links to create a generally elliptical motion path for exercise equipment.

Reciprocally linked footplates resolve health issues from static postures by enabling continuous horizontal and vertical movement.

A motorized paddling simulator adjusts cable tension via a controller to mimic water resistance during propulsion and recovery phases.

Gymnastic machine slats incorporate localized edge reliefs to alert users of their proximity to the frame, preventing accidental falls during exercise.

Replacing manual weight stacks with an electric linear motor eliminates bulky equipment and enables precise resistance adjustments through electronic control.

Segmenting the rotating mechanism into two independent units resolves the contradiction between structural simplicity and versatile range of motion.

Control circuitry adjusts treadmill belt velocity based on detected user body and leg swing speeds to mimic natural walking motion.

An elastic member drives a movable member to adjust belt tension dynamically, preventing slipping while reducing belt degradation.

Segmented running belt pieces with elastic elements provide a bouncing effect while complementary surfaces prevent gaps between units.
