Walking Sticks TRIZ Cases

A three-part pole buffer uses a hard intermediate piece and locking sole to stop twisting, enable tool-free replacement, and reduce material waste.

A magnetic cane caddy mounted near the wheelchair armrest improves cane access and secure retention without wheelchair modification.

A screw motor, nut support, and connecting rods automate sunshade rib opening and closing while keeping the structure simple and stable.

Light and wind sensing automate umbrella opening and angle rotation, improving outdoor shade convenience, stability, and safety.

A flexible U-shaped hook lets canes, crutches, or tools attach one-handed to varied surfaces while staying securely positioned.

A deformable quadrilateral linkage replaces the triangular umbrella arm structure to cut adjustment resistance and lock the canopy angle smoothly.

A layered bulletproof umbrella canopy uses energy-absorbing materials and viewing openings to provide portable cover from bullets and shrapnel.

Balanced auxiliary rods and a sliding seat linkage stabilize the expanded cane seat while preserving foldable portability.

A rotatable handle with a switching rod and spring-locked slots lets one walking aid switch between crutch and trekking pole use.

A gas spring inside the hollow umbrella pole stores closing force and lifts the lower hub to reduce manual effort when opening large umbrellas.

A quadrilateral linkage and slider replace ropes and springs, making umbrella opening and folding easier, safer, and more stable.

Split cantilever arms and a locking sliding sleeve cut umbrella packaging volume while enabling practical canopy angle adjustment.

A movable second handle snaps into fixed positions or nests within the first grip, improving height adaptability without complex deployment.

Split cantilever arms and a sliding lock mechanism cut umbrella packaging size while allowing convenient canopy angle adjustment.

An integrated central and upper pivot ring closes exposed gaps in a foldable parasol, blocking dirt and rainwater while reducing wind wobble.

A modular crutch handle integrates vibration and heating while keeping battery and motor parts easy to assemble, remove, and replace.

Camera-based path analysis in smart glasses replaces slow cane tapping with audio and vibration guidance for safer mobility.

A single-piece elastic locking element lets a pole wrist strap attach and detach securely with one hand, even when gloves reduce dexterity.

Contoured thumb channels and a palm cradle let a Nordic walking pole grip stay strapless while reducing wrist and thumb strain.

A pull sleeve and elastic fastener control segmented umbrella rod retraction to avoid rib contact with the hand and keep the closed length compact.

Layered sound-absorbing fabrics and an air gap cut noise in flexible sun or rain covers without the weight of rigid acoustic panels.

Linear arm retraction inside the umbrella body cuts opening space and preserves smooth operation in confined installations.

A nested telescopic second handle adds adjustable two-user grip for different heights while keeping deployment, locking, and storage compact.
