Artificial Legs TRIZ Cases
- Prosthetic Foot Radial Blade Deflection for Stability
Radial blade deflection in a prosthetic foot provides stability while accommodating diverse user activities through segmented structural design.
- Non-snag Prosthetic Foot With Rotational Wear Member
A prosthetic foot uses a rotatable symmetric wear member to maintain even surface contact and traction during ambulation.
- Prosthetic Foot Insert with Dual-Modulus Forefoot
Dual-modulus materials resolve ankle moment issues during uphill walking by allowing the forefoot to deform easily while maintaining heel stability.
- Overmould Attachments for Prosthetic Foot Adaptability
Segmented base plates with replaceable overmoulds resolve trade-offs between customization and manufacturing cost while seal covers protect against debris.
- Electric Vacuum Pump for Prosthetic Socket Evacuation
An electrically activated pump system evacuates the interior of a prosthetic socket to secure the device on the residual limb.
- Adjustable Energy Release Mechanism for Passive Prostheses
A locking mechanism controls cable tension to time energy release from a passive carbon fiber foot.
- Hybrid Artificial Limb Knee Joint with Passive Hydraulic and Active Motor Control
A hybrid artificial limb knee joint combines passive hydraulic cylinders with active driving motors to deliver precise torque.
- Hydraulic Orthotic Joint for Dynamic Alignment
A hydraulic unit adjusts the basic setting of an orthotic joint to maintain optimal alignment.
- Multi-Strutted Prosthetic Shank with Carbon Fiber Gaps
Segmented carbon fiber struts prevent interlaminate shear stresses, resolving the strength-weight trade-off in prosthetic limbs.
- Breathable Residual-Limb Socket with Air-Permeable Liner and Venting Adapter
Air-permeable pouch liner enables evaporative cooling while adapter drainage holes remove accumulated moisture to prevent skin breakdown.
- Transtibial Socket with Patellar Tendon Clearance
A prosthetic socket design featuring a lowered edge and gap to enhance anterior tibial condyle support.
- Prosthetic Knee Hydraulic Joint with Rotary Hub and Vanes
A prosthetic knee joint uses a rotary hub and vanes to actuate fluid flow through a hydraulic system for controlled impedance.
- Effective Shape Controller for Lower Limb Prosthetics
A control system adjusts joint torque using effective shape constraints derived from center of pressure data.
