Artificial Legs TRIZ Cases
- AI Prosthesis Tuning for User-Preferred Ankle Stiffness
Biomechanical sensor data trains AI to predict preferred prosthesis ankle stiffness, cutting lengthy manual tuning for each user.
- Clamping Disc Freewheel Locking for Power-Loss Grip Holding
Asymmetrical clamping discs and jamming rollers hold gripping force after power loss while allowing free rotation and simpler manufacture.
- Magnetic Prosthetic Joint Actuator for Secure Heel Height Locking
Permanent magnets lock heel height settings in a prosthetic or orthotic joint actuator, preventing drift while allowing precise adjustment.
- Magnetic Prosthetic Joint Locking for Adjustable Heel Height
Opposing magnets lock or release a prosthetic actuator, enabling precise heel height adjustment without sacrificing joint stability.
- Prosthetic Socket Lock With Radial Elements to Prevent Slack
Circumferential locking elements secure a prosthetic liner insert with easy release, reducing slack, noise, and incorrect locking.
- Magnetic Locking Actuator for Adjustable Prosthetic Joint Alignment
Opposed magnets lock or release an actuator so prosthetic and orthotic joints can adjust heel height and length with stable positioning.
- Jamming Roller Lock With Passive One-Way Locking Force
Uses jamming rollers and asymmetric disc recesses to lock against external force without continuous power while allowing free rotation in one direction.
