Joints TRIZ Cases
- Blind Fastener Installation with Passive Compliance Alignment
Passive compliance aligns blind fasteners for quick, precise swaging without high-precision sensors, reducing system weight and cost.
- Modular Robot Waist Skeleton for Three-DOF Flexibility
Segmented swing, bend, and rotate actuators give a robot waist human-like three-DOF motion without relying on a rigid integral structure.
- Rehab Robot Arm Gravity Balancing with Switchable Pulley Locking
Spring-wire rope balancing with lockable guide pulleys offsets arm torque and supports left-right rehab mode switching in a compact robot arm.
- Robot-Arm Screw Coupling for Vibration-Robust Force Sensing
Indirect force sensing uses spring displacement between robot and screwdriver to keep wall screwing reliable under vibration and impact.
- Magnetic Joint Position Sensing With Co-Prime Pole Rings
Co-prime inner and outer magnetic rings enable compact, accurate revolute joint sensing while limiting ring-to-ring interference.
- Positive Pivot Positioning for Drift-Free Dental Unit Arms
Spring-loaded friction plates hold dental unit arms against drift, while a pneumatic release lets users reposition the pivot shaft easily.
- Swiveling Receptacle Mounting for Multi-Angle Tool Positioning
A profiled receptacle mount enables multiple angular tool positions without complex multi-part swivel assemblies, simplifying setup and use.
- Movable Link Structure With Sliding Spherical Tips for Compact Head Motion
Spherical-tipped links slide on a connecting part to deliver multi-direction head motion without long beam members, enabling a smaller movable structure.
