Propulsion Power Plants TRIZ Cases

Wireless lanyard detects operator absence to activate GPS and engine controls, resolving manual response delays during man overboard events.

A ship maneuvering system uses an output control device to differentiate propulsion power source outputs for directional steering.

A pump circulates coolant through a flow path featuring an upper air vent to remove trapped gas from the motor control device.

A floating valve seal in the exhaust passageway moves upward to block water ingress into a rotary engine jet boat propulsion system.

A linkage system couples a first drive to a second support, moving the outboard motor body vertically while rotating it relative to the boat.

Segmenting the shift finger from the rod reduces gearbox access hole size, increasing casting strength and preventing oil leakage.

An angled drive shaft and thrust redirection plate redirect reverse thrust to reduce drag and prevent obstruction fouling in shallow water.

Dual oxygen sensors monitor exhaust gas concentration upstream and downstream of a catalyst member in a water jet propulsion system.

Kit prevents clutch burnout by adding a gear box assembly that reduces drive shaft speed and load.

A vertically adjustable electric jack plate system powered by a rechargeable battery and controlled via a wireless remote.

Segmented exhaust outlets in the propeller hub prevent blade ventilation, maintaining thrust efficiency.

Positioning arm and cam support shafts horizontally while orienting the valve shaft vertically reduces horizontal space occupation in outboard engine units.

A sterndrive fixation system redirects propulsion force to the structural base using separate brackets.

A boat drive coolant line contacts an electric motor and a battery to cool both components using a single thermal circuit.
