Muscle Exercising Devices TRIZ Cases

A PMSM-based exercise system raises requestable torque during outward motion to deliver higher concentric resistance with continuous tension control.

A shared weight stack and rotating pad structure combine hip abduction, adduction, and cable exercises in one compact training setup.

Adjustable tension elements in a compressive glove oppose finger closure, enabling wearable grip training while easing swelling and discomfort.

Dynamic motor torque and a state space inertia model let digital exercise equipment emulate flywheel workouts without manual tension changes.

A movable trolley, single-dial control, and concealed motor make wall-mounted resistance training more compact and easier to use.

Portable cable resistance is combined with sensor-based movement tracking to support variable exercise loads and therapy feedback.

Series-linked weights and electromechanical resistance preserve realistic haptics while enabling seamless load changes and custom tension curves.

A resistance-band retrofit adds peak variable resistance at phase transition, improving eccentric control on weight stack machines.

A pedal extension moves the foot closer to the seat and secures heel contact, helping TKA patients increase knee ROM without therapist assistance.

Multiple rotating shafts let one cable puller change pulley direction and exercise posture, enabling varied training angles on a single machine.

Elastic support loops paired with a restrictive panel prevent band sagging and arm slippage while improving lifting stability and shoulder relief.

Combining a weight stack with motorized resistance preserves haptic feedback while enabling on-the-fly load adjustment during exercise.
