Power Plants Using Propulsion Unit Combinations TRIZ Cases
- Battery Equivalent Fuel Consumption for Hybrid Power Distribution
Dynamic equivalent fuel consumption lets hybrid systems allocate battery and generator power more efficiently under irregular loads.
- Outboard Motor Planetary Gear Layout for Steering Torque Balance
A planetary gear counter-torque layout reduces the power needed to hold an outboard motor steering angle while keeping the lower case compact.
- Outboard Motor Layout for Passive Cooling and Lower Drag
Positioning the electric motor above the anti-cavitation plate uses natural water flow for cooling while keeping the lower case smaller and lower-drag.
- Reduction-Reversing Gear Cooling Control for Low-Noise Operation
Variable refrigerant pump control matches generator motor load and oil temperature to cut gear-unit noise and power use while maintaining cooling.
- Small Watercraft Auto-Navigation With Adaptive Control Patterns
Adaptive control patterns switch propulsion and steering by heading error and distance, helping small watercraft reach destinations faster with less energy.
- Planetary Hybrid Marine Propulsion for Mode-Switching Efficiency
A planetary gear and motor-generator let marine propulsion switch between engine and electric drive while improving fuel use and battery charging.
- Hybrid Marine Propulsion with Planetary Gear Mode Switching
A planetary gear and motor-generator let marine propulsion switch between mechanical and electric drive to improve fuel use and onboard power management.
- Auxiliary Electric Thruster Control for Low-Speed Marine Propulsion
Below troll thrust, an electric auxiliary thruster maintains stable vessel speed while cutting noise and CO2 from engine state switching.
