Walking Aids TRIZ Cases

Depressions in the elastic molded cushioning body accommodate anterior knee protuberances, distributing pressure uniformly across the lower leg.

A knee joint uses a series elastic actuator and crank mechanism to convert linear motion into rotational movement.

A tethered ankle-foot prosthesis emulator provides programmable torque to simulate prosthetic devices.

Spring-loaded ball locking in telescopic tubes enables quick height changes while an abutment mechanism memorizes the last position.

A removable bag assembly attaches to rollator shafts via lumen insertion and flange retention.

Pivoting strap actuators raise restraints between legs to prevent falls, eliminating complex harnesses that require caregiver assistance.

Controlled treadmill displacements train balance while a safety harness prevents fall injuries during aggressive perturbation exercises.

A control system processes strut deflection angles to determine user motion intentions and generate platform movement signals.

A mobility aid uses a reversed tricycle frame to support patient weight through buttocks and elbows while maintaining natural gait patterns.

A prosthetic joint actuator adjusts movement resistance using signals from a detection device monitoring muscle co-contractions.

Pressure-sensitive walker grips detect hand force and trigger vibration alerts to guide users toward upright posture.

Pivoting the footrest clears caregiver space, resolving adaptability complexity trade-offs.

Sliding side struts in support tubes distribute weight forces, resolving high stress on front frame connections while ensuring space-saving foldability.

Adjustable crossbars and a laterally movable seat accommodate varying user sizes without fixed width constraints.

A walker adjusts front-to-rear wheel distance using a gear set, reducing turning radius in auxiliary mode while increasing stability in driving mode.

Segmented frame modules couple reversibly to adjust lateral stance, resolving tipping risks under lateral loads while maintaining portability.

A trunk exoskeleton uses torque generators to provide resisting force only when the wearer bends forward beyond a set angle.

Radial arm mechanism guides circular movement to improve muscle strength while maintaining safety.

A movable walker support uses a cam slot and threaded rod to adjust leg inclination angles.

A three-wheeled mobility device uses a pivotable front fork linked to a forearm support bar for steering.

A collapsible walker uses a hinge mechanism to collapse into storage.

REGENmax protocol reverses genitalia atrophy by using acoustic shockwaves to stimulate angiogenesis and restore erection sustainability.
