Hubs TRIZ Cases

An actuator moves the rotor relative to the connection assembly, resolving the trade-off between vehicle adaptability and structural complexity.

A pulser ring rib extends toward a hub receiving portion to suppress plastic deformation and maintain shape under external forces.

Integrated ducts in the axle stub eliminate external hoses, reducing weight and installation space while maintaining structural strength.

A spacer presses inner races against a movement restricting section to prevent slippage in motorized bicycle hubs.

Segmented hub body supports removable sprocket and brake rotor structures via torque-transmitting profiles, resolving attachment complexity.

An asymmetric two-stage stiffness axle-shaft system creates out-of-phase torsional responses between shafts to cancel wheel hop resonances during acceleration.

One-sided axial bearing holding eliminates sleeves in a star ratchet hub, reducing weight while maintaining force transmission reliability.

Segmented cassette design transmits tangential forces via grooved surfaces to a durable support structure, reducing sprocket weight and manufacturing costs.

Inductive sensors measure rotational position in bicycle hubs, eliminating heavy torque tubes and manual calibration for accurate power measurement.

Axis-pivoted spokes fold rim sectors longitudinally, reducing radial dimensions and weight while improving impact resistance.

An operating lever moves axially to a rotary position near the clamping component, preventing inadvertent clamping force changes while maintaining stability.

A wheel hub intermediate chamber stores hydraulic oil to increase system capacity without adding external tanks.

Radial relative movement between tapered rollers and a retainer allows incorporation into an outer ring rib, resolving assembly interference.

Axial spoke guides in the hub flange secure spokes while reducing radial expansion and weight.
