Hubs TRIZ Cases

A multi-hub wheel assembly uses a high-strength intermediate hub nested within an outer wheel to enhance structural support.

Rotating sleeve adjusts camber and toe via locking pin to reduce tire wear from axle flexing.

A wheelchair wheel disk uses radial ribs to transfer loads between the rim and hub, creating a lightweight structural component.

Segmented intermediate elements prevent corrosion and ease removal by clamping between the hub device and brake disc grooves.

Dynamic magnetic force modulation reduces ratchet tooth contact and friction noise during reverse pedaling.

Tapered grommets and cylindrical bearings resolve steering precision trade-offs by constraining axle movement to reduce wavering.

Shifting cage contact points to the polar region reduces sliding friction and heat dissipation in bearing units.

Ultrasonic transducers detect sound wave reflections through a pinion gear to measure preload force, replacing labor-intensive rolling torque calculations.

A deformable damper assembly compresses against bicycle wheel spokes to apply axial damping forces.

Rotating sleeve with locking pin adjusts camber, toe, and thrust to counteract axle flex under load.

A bicycle skewer rod lock assembly uses a security nut sub-assembly with peripheral keyways and a rotatable sleeve to secure the wheel.

Galvanized coating on hub bearing collar prevents oxidation without slowing production speed.

Replacing compression springs with magnetic biasing reduces friction and noise in the freewheel state by eliminating progressive force increases.

An angled pinion axis in a portal spindle assembly maintains wheel camber without altering track width during suspension travel.

A multi-translative roll assembly uses independent gear-driven rolls on a rotatable carrier frame to move objects in multiple directions.

A variable compliance metallic wheel integrates a hub-mounted potentiometer to measure torque directly within the drive train.
