Electric Propulsion Mounting TRIZ Cases

A suspension system using independently controllable stators to generate thrust forces for active steering and traction management.

A cooling system unit positioned externally to an electric energy storage device absorbs collision kinetic energy.

A vehicle body structure positions a battery cover on a seat rail bridge to protect the battery.

Oil cools bearings and magnets then transfers heat to coolant channels, eliminating separate oil coolers.

Sequential core and coil oil passages boost heat transfer coefficients to resolve uneven cooling in high-power-density electric vehicle motors.

Lateral cooling elements with external ribs dissipate heat from electric motorcycle components via direct air contact.

A controllable speed differential uses planetary gears to distribute torque between output shafts.

Electric axle drive manages differential torque between output shafts using a clutch connected to the sun gear, preventing wheel spin during traction.

Nested housings secured by a common attachment reduce packaging footprint and structural complexity in tiered battery arrays.

A battery heating device merges engine and battery circuits via a three-way valve to mix liquids for thermal transfer.

Pivoting the compression spring with the frame eliminates complex levers, ensuring stable pressing force while simplifying the auxiliary roller structure.

A pivot lever battery lock secures energy storage blocks in industrial trucks using mechanical rotation.

Crossed-axis gearing in a screwing tool resolves the contradiction between compact size and high torque for efficient battery swapping.

An inverted flap system mounts the actuating lever and flap on an inner side surface, eliminating exterior protrusions that cause entanglement or damage.

Merging multiple cooling plates into one unit eliminates complex hose connections and trapped air, improving system reliability.
