Electric Propulsion Mounting TRIZ Cases

Rotating reducer gear and motor shaft create pump-free lubricant flow to cool the motor, cutting transmission weight and complexity.

A second motor on the transmission output maintains tractive power during gear shifts, improving EV driving comfort and range.

A sacrificial side-impact zone lets the battery pack shift laterally via the cross member, absorbing crash energy and reducing module damage.

A radially inner coolant inlet guides flow to the hottest stator end-winding regions, improving cooling and available machine power.

A shared fastener joins the gear case and power conversion case to the motor case, cutting package size while preserving strength, sealing, and vibration resistance.

By merging the battery pack with the EV chassis, this case cuts mass, improves space use, and adds torsional and bending rigidity.

An external shift controller moves the axle coupling to neutral when vehicle controls fail, enabling towing and maintenance without disassembly.

A raised, rear-tilted center frame boosts vehicle-body distortion stiffness without adding tunnel bulk or reducing occupant space comfort.

Routing cables, lines, or rods through hollow battery stretchers saves vehicle space, protects connections, and preserves passenger room.

A front absorbing structure isolates battery pack crash loads from the frame, protecting the pack while enabling a lighter vehicle body.

A controller switches coolant flow patterns by inverter output to prevent overheating while avoiding unnecessary energy use in EV cooling.

A fixed inner lid lets the wall plate swell outward to open a larger vent gap, securing gas discharge flow when battery case pressure rises.

A nested three-planetary layout generates two near-equal output torques above input torque while keeping the drivetrain compact and efficient.

A draw-out plate under the seat shields EV inverters from rain and dust while enabling maintenance without removing the seat.

Axle-mounted motors replace angle-limited driveline joints, letting lift axles raise fully yet add traction when lowered on heavy trucks.

A spline-based adapter links an electric motor to a spider cage, enabling lower-cost gas-to-electric vehicle conversion without major drivetrain changes.

A dual-material side and fixation structure improves battery module fit, insulation, and clamping strength under vehicle loads.

Replaceable guide blocks use friction and guiding surfaces to align and secure removable forklift batteries while reducing insertion wear.

A recessed counterweight layout shields the excavator emergency stop switch from debris and obstacles while keeping ground access for shutdown.

Three coaxial axial-flux machines split wheel torque and add differential boost power, raising speed range without oversizing motor diameter.

Box-like side and end brackets let oversized truck battery packs mount beyond side rails while improving torsional rigidity and side-impact protection.

Intersecting reinforcement in overlapping battery cases boosts vibration resistance while preserving cell packing efficiency and compact size.

A lower interference zone between the power generation and drive units disperses frontal collision loads and helps protect brake pedals.

A three-way valve links large and small fuel inlets so one vehicle can accept different nozzle sizes, speed fueling, and prevent overflow.

By shifting bumper reinforcement away from the decorative member, the front bumper gains more retraction space to absorb pedestrian impact.

A semi-staggered winding layout and complex weld twisting cut coil types, concentrate welds on one side, and reduce stator losses.

A multi-chamber reinforcement inside a hollow battery housing support absorbs crash energy while increasing stiffness without added weight.

Separating battery housing from underbody stiffening simplifies production, improves load paths, and reduces accident damage risk.

A perforated reinforcing element strengthens the battery housing, improves crash load distribution, and limits added weight and space.

Fluid-fed pins and thermally conductive insulating resin improve stator end-winding heat removal while preserving electrical isolation.

Detection features on the shift collar let one sensor track axial position and rotational speed, improving axle shift reliability.
