Crutches TRIZ Cases

Continuous adjustment of grip, arm support, and ground contact improves load distribution, comfort, and stability while reducing fatigue and fall risk.

A vacuum base and pump let a forearm crutch stand upright on the floor, reducing tipping risk and user intervention on varied surfaces.

A contoured grip and variable-support forearm cuff shift load away from the hands and wrists to reduce fatigue during prolonged crutch use.

Segmented buffer sections with varied thickness let a hands-free crutch foot mimic natural foot motion and reduce walking discomfort.

A tactile joystick and self-leveling drive let this walking cane follow user movement without lifting, improving stability and mobility.

Independent spring tension in each crutch leg improves shock absorption, traction, and stability on uneven or inclined ground.

A handgrip-actuated slide and engaging element enables fast, stable walking aid length adjustment without bulky bolts or hydraulic parts.

A handle-operated internal slider locks and releases the adjusting tube to simplify crutch height adjustment while reducing weight and jamming risk.

A frame with coupler members and matched fasteners mounts bottles to crutches or walkers, improving hands-free access without upsetting balance.

An internal spring and sliding lower leg cushion crutch impacts while cutting noise, pinching risk, and cost.

Weight-bearing shifts from the armpit to a saddle and leg restraints, enabling hands-free mobility while reducing underarm discomfort.

Telescopic locks, adjustable hinges, and straps stabilize an injured leg while reducing clinic visits for walking-aid adjustments.

A spring-assisted folding mechanism lets support legs adjust to user height while reducing storage space.

An arm rest cradle distributes body weight through the elbow and upper arm, reducing hand and wrist stress.

Segmented retaining clips enable quick grip replacement without disassembly, resolving the trade-off between adjustment ease and structural reliability.

An oval composite leg-arm anchors the handle and cuff for continuous adjustment, eliminating complex springs to resolve weight and corrosion trade-offs.

Molded fibrous layers absorb polymer and cure to prevent delamination from cutting fibers.

Load and motion sensors verify step duration and movement thresholds to improve rehabilitation compliance tracking.

Elastic fastening members press horizontally into a groove to secure crutches, reducing user strength and resisting vertical impacts.

A sensory substitution device uses a shape-change mechanism to provide kinaesthetic output based on spatial sensor data.

A cone-shaped glider accessory anchors filamentous decorations via twist lock projections to stabilize walker movement.

A multi-function crutch uses insulating material over metal poles to prevent temperature extremes while supporting packages via a detachable netting system.

A walking cane features a motorized armrest and sliding deployable legs for stable user support.

A walking assistance device uses a tiltable front axle to keep wheels grounded during movement.

Coupling two walking aids creates a compact tripod structure that eliminates large footprints and prevents accidental tipping during storage.

A removable limb-support assembly mounts to assistive devices via a mounting aperture and brace, enabling lower limb elevation during continuous mobility.

Swivelable support legs deploy from the upper shaft region to resolve contradictions between stability and design complexity in walking aids.

A swing walker system uses suspension collars to offload weight-bearing limbs during normal gait.

Coil springs inside pipe adapters absorb shock at the underarm rest, resolving comfort versus complexity trade-offs.

Composite material construction enables a crutch to return stored energy for user propulsion while reducing wrist strain.

Segmented sole layers and dynamic latching resolve the contradiction between attachment reliability and ease of detachment.

Flexible shaft fingers with protrusions snap into leg apertures, eliminating debris-trapping openings while composite materials resolve wear resistance.

Magnetic coupling stabilizes crutches against falls, eliminating the need to bend down or find specific support locations.

Frusto-conical adjustment pins reduce vertical play and noise while ratchet locking maintains structural stability across different user heights.

Segmented display panels attach to walkers via grommets, resolving the trade-off between aesthetic customization and device weight.
