Walking Aids TRIZ Cases
- Foldable Knee Scooter Hinge and Latch Mechanism
Segmentation and dynamics principles resolve the contradiction between portability and structural stability in knee scooters.
- Brace Joint Mechanism with Replaceable Insertion-Fitting Member
Replaceable insertion-fitting members adjust rotation limits, preventing damage to regulation parts during rehabilitation.
- Convertible Walker Fall Seat Rotation Mechanism
Rotating fall seats catch users during configuration changes, resolving conversion complexity and stability issues in mobility devices.
- Skating Machine Crank Lock Prevention
A resilient tension means prevents double crank locking at extreme positions by maintaining alignment and providing counteracting force.
- Upright Walker Extension Cross-Member Attachment
Removable cross-member attaches to walker braces, supporting lateral and vertical members that distribute weight to maintain upright posture.
- Adjustable Stair and Ramp System for Variable Incline Simulation
A drive system displaces tread surfaces vertically to form stairs with adjustable rise heights.
- Walking Aid Synchronous Braking and Height Adjustment
A walking aid with a telescopic seat and linked brake handle for height adjustment and synchronous wheel braking.
- Automatic Walker Brake System Using Hand-Position Sensor
An automatic braking mechanism on a walker detects standing or sitting grips via sensors to prevent unintended rolling while preserving mobility during walking.
- Sliding Joint Elastic Module for Motion Assistance
A supporting module uses a sliding joint and elastic module to provide adjustable support for motion assistance.
- Physical Therapy Roller Table for Slip and Trip Simulation
A physical therapy roller table transitions between powered and free motion modes to simulate slips and trips.
