Hubs TRIZ Cases

A hub apparatus integrates a charging stand to transfer power via electromagnetic induction between coupled coils.

Integrating a sensor ring adjacent to the brake disc on the hub resolves space constraints while maintaining measurement precision and reducing noise.

One-piece tubular axle spindle with friction-welded transition zone reduces weight and stress concentrations in heavy-duty vehicles.

Axial freewheel mechanism in bicycle hubs uses roller bearings and spring preload to maintain axial positioning stability under high loads.

A spoked wheel system nests axles inside hubs to reduce stack height and eliminate bulky cases.

A detachable cap aligns with wheel openings to conceal unused holes, enabling versatile wheel installation across different hub assemblies.

A secure locking hub system uses a splined fastener and axial locking ring to immobilize vehicle wheels without axle modification.

A hub bearing design integrates air ports into the outer ring to support active tire inflation systems without modifying the rotating assembly.

A bicycle freewheel hub uses a planar detent coupling surface to transmit torque between the driver and hub sleeve.

A stator angle correction device adjusts encoder signals to maintain measurement accuracy during wheel steering.

Segmented thrust washers and retainers position bearing rollers around a planet shaft, reducing axial length and manufacturing costs.

Hollow shaft member supports left and right driving disks for individual rotation, resolving assembly complexity and positioning accuracy issues.
