Power Plants Being Motor-Driven TRIZ Cases

Shared fluid circuits link motor cooling, lubrication, and clutch actuation to cut installation space while maintaining operation across modes.

Using speed-change signals from existing sensors, this case shows trim control that cuts turning diameter without adding a steering angle sensor.

A compliant frame isolates the integral oil cooler from the crankcase to absorb thermal expansion mismatch, reducing stress and leak risk.

Direct stator-fed raw water and a hull heat exchanger keep a marine jet engine cool without pump failures, reducing overheating and corrosion.

A movable intermediate member and paired springs absorb acceleration and deceleration torque fluctuations in vessel propulsion gear trains.

Starter-generator motor controls engine RPM via torque application to prevent hydrolock during high-speed reverse gear shifts.

Sealed enclosure houses high-pressure pumps and filters to manage alternative fuel supply, reducing retrofit costs and vessel space requirements.

Dual elastomeric dampeners in the transom bracket isolate stern drive vibrations, reducing noise and wear while maintaining structural support.

A watercraft control system uses load sensor data and decision logic to detect propulsion malfunctions.

Bevel gears reverse the drive shaft to rotate the front propeller, eliminating hollow outer shaft alignment and lubrication issues.

Lateral offset positioning moves the lower unit away from the helm platform, resolving interference during storage while maintaining maintenance access.

Integrating an elastic stopper with the crankcase cover reduces component count and assembly steps while mitigating hull shock during rapid vertical motion.

A jet propulsion bucket moves between retracted and receiving positions to manage water thrust.

Dynamic control strategy varies engine speed and propeller pitch independently to resolve fixed relationship inefficiencies at lower speeds.
