Electric Motor Starters TRIZ Cases

When vehicle speed sensing fails, auto-stop is blocked to avoid unintended engine shutdown and preserve reliable stop-state control.

Physically separated starter solenoids and a non-incendive circuit contain cranking spark risk for safe engine starting in hazardous areas.

A non-detachable terminal cover blocks bridging and short-circuit access in vehicle starter solenoid switches while preserving external control.

A three-mode stand-by control shuts down the engine when possible, cutting idling energy use while preserving cab comfort and quick restart.

Load connection detection enables a portable jump starter to output starting current only when properly connected, improving ignition safety.

Monitors doors, belts, gear, brakes, and slope to keep an ISG-equipped vehicle stopped and prevent unintended movement during exit.

A key-operated switch combines engine starting and speed selection to cut parts, wiring complexity, and failure points in outdoor power equipment.

A load access detecting circuit enables portable vehicle starting current only after proper connection, improving ignition safety and depleted-battery starting.

Relay-switched 12V and 16V battery cell configurations deliver extra jump-start power for deeply discharged batteries without wasting energy.

After long storage, a relay controller switches starter supply between two batteries using voltage and charge state to avoid start failures.

A 3-phase BLDC ISG balances back-EMF against battery voltage to raise torque at speed, cut short-circuit current, and enable sensor-less operation.

A second ring gear acts as a sensor wheel to detect rotor position accurately while avoiding extra parts, added space, and starter engagement issues.

An ISG controller uses auxiliary power after Key OFF to stop the crankshaft at a non-compression angle, cutting restart torque demand.

Combining engine start and speed selection in one key-operated assembly reduces wiring, components, and failure points in outdoor power equipment.

Measured operating points replace complex generator modeling, enabling precise excitation control under load changes with simpler commissioning.

Sensor checks for seatbelts, doors, and passenger authentication let an autonomous vehicle start only when boarding safety conditions are met.

When preconditioning could drain fuel or charge too far, the vehicle sends corrective actions to the mobile app to preserve driving range.

A brake-lever signal starts the electric motor only at safe lever positions, simplifying repeated chainsaw engine restarts.

Coordinated drones use robotic arms and conductive end effectors to deliver jump-start power when no alternate vehicle or source is available.

A drill-driven cylinder engages a flywheel cup to start pull-start motors, then disengages at higher speed for free motor operation.

Motor current stall detection guides forward and reverse crank rotation to place the piston for reliable single-cylinder engine restart.

Oil pressure monitoring gates engine cranking and stops start-up when lubrication is insufficient, helping prevent dry-running damage.

A normally closed relay shorts circuit ends of a resistor to supply full battery voltage directly to an electric motor.

Series wiring synchronizes dual starter motors to eliminate noise from asynchronous engagement and ensure reliable engine starting.

Microcontroller prevents premature ignition status updates during starter motor engagement by monitoring battery state of charge to avoid power-down resets.

Minimal risk maneuver mode maintains system deactivation until engine restart, preventing accidents when control handover fails.
