Wheel Based Transmission TRIZ Cases

Integrated holding portion and bearing support the torsion bar intermediate section, preventing bending deformation and uneven gear wear.

A stationary housing friction ring transmission reduces axial length, resolving bulky design constraints in compact electric bicycle drive units.

A second independent motor powers reverse movement to eliminate manual pushing effort during parking maneuvers.

A motorcycle synchronous transmission uses epicyclic gear mechanisms to replace variable ratio belts.

A hub device reduces passive rotational force speed to enable continuous regenerative operation without exceeding motor limits or requiring cut-off devices.

Segmenting the motor and battery resolves the contradiction between simplified fitting operations and compatibility with traditional mechanical gears.

A drive unit transmission selects torque delivery gears to shift ratios while maintaining constant motor rotation direction.

Segmented fairing members adapt to handlebar heights while reducing wind resistance and propelling effort.

A star gear torquer reduces energy loss from gear friction by segmenting the planetary mechanism into independent sets with shared lubrication.

Nesting the canister inside a seat cavity shields it from dust contamination while preserving fuel tank volume.

A motorcycle frame crossmember overlaps pivot plate joints to enhance structural rigidity without adding weight.

A bicycle suspension system integrates stroke and damper adjustment units for dynamic ride tuning.

Integrating a torque sensor inside the hub reduces lead wire length, resolving complex routing issues while maintaining structural integrity.

A compact bicycle drive unit integrates a motor and crank axle coaxially to combine pedaling and motor forces efficiently.

Radial gear selectors shift planetary gears inside the hub, reducing user force and minimizing added width.
