Resilient Force Resistors TRIZ Cases

Concentric resilient rings strengthen fingers, thumbs, and hands while addressing limited rehabilitation effectiveness in conventional devices.

A foot training device uses a central fulcrum and four elastic projections to strengthen foot muscles through bending resistance.

Pivoting arms connected by tension members deliver bidirectional resistance, eliminating grip changes during adduction and abduction exercises.

Adjustable elastic chest wrap activates accessory muscles through controlled compression.

A torsion spring reel mechanism provides linear resistance for Pilates carriage motion.

A physical training apparatus applies adjustable resistance vectors to multiple body segments via elastic tethers and tracking mechanisms.

A respiratory rehabilitation apparatus adjusts exhalation and inhalation pressure through rotatable housings and elastic members.

Adjustable elastic force grooves on arm bodies allow selective spring coupling positions, enabling multi-step resistance customization without complex redesign.

Variable tension devices adjust surface compliance and orientation to resolve the trade-off between structural stability and movement intensity variation.

Compact circular base with radial connectors and elastic straps enables full-body rotational workouts without bulky mechanical systems.

A head harness supports a pivotable plate biased toward a collapsed position to engage the back of the user's head during resistance exercises.

Magnetic interlocking units enable seamless weight changes without stopping, resolving the trade-off between adaptability and operational complexity.

A movable spring anchor bar integrates an elongated stop member to enable single-hand adjustment of the carriage position.

Layered polyurethane foam densities in a therapeutic exercise pillow maintain neutral spine alignment, reducing lumbar tension for users with spinal stenosis.

Sliding sleds on a telescopic frame provide adjustable resistance to target neck, chest, and arm muscles simultaneously during push-up exercises.

A resistance band system connects leg wraps to a strap via connectors to provide adjustable elastic force during motion.

Rotating the support member eliminates metal collision noise while maintaining reliable connection for adjustable exercise positions.

Sliding enclosures on a platform base provide 360-degree resistance, enabling seated exercise without leaving the workspace.

A friction wheel mechanism drives an endless belt to match user running speed, eliminating safety risks from motor-driven treadmill overspeed.

Segmented partitions and flexible shells deliver controlled resistance for muscle development without swaddling limitations.

Porous protective pads vent trapped air to eliminate pad slap and restore bounce height in ground-level trampolines.

Pivotable boom structures rotate to incline the horizontal exercise plane, resolving the trade-off between fixed simplicity and adjustable muscle engagement.

A portable exercise device uses a pneumatic piston to generate adjustable resistance through variable air pressure.

A compressible wrap expands handle diameter to increase muscular resistance during sports equipment use.
