Propulsion Power Plants TRIZ Cases
- Outboard Motor Shift Control for Mechanical Remote Compatibility
Direct wire-position detection lets a shift-by-wire outboard motor work with mechanical remote controls without a hull-side conversion unit.
- Marine Vessel Speed Control Using Averaged Hull Motion
Using moving averages of hull vertical motion, this case smooths vessel speed changes in waves to reduce repeated acceleration and improve ride comfort.
- Marine Propulsion Wave Control for Head and Following Seas
Wave-direction sensing adjusts speed only in head seas to reduce hull attitude change and improve ride comfort without destabilizing following seas.
- Trolling Motor Steering Gear Assembly for Precise Thrust Direction
A multi-stage planetary gear assembly and reversible DC motor improve trolling motor shaft rotation control and thrust direction precision.
- Outboard Motor Trim Sensor Fault Detection for Actuator Restriction
Periodic comparison of current and stored trim angles detects small sensor offsets and restricts actuator motion to prevent improper trim control.
- Autonomous Hydrofoil Control With Sensor-Driven Lift Adjustment
Real-time sensors and adjustable foil members control lift and propulsion to cut drag, improve ride height, and remove manual error.
- Marine Drive Gearcase Nose Caps for Cooling Water Pressure
Interchangeable nose caps let marine drive gearcases adjust cooling water flow and maintain pressure when high mounting reduces intake.
- Marine Motor Cover Structure for Noise Damping and Gloss Finish
A layered DLFT, NVH foam, and ASA cover improves marine motor noise and vibration damping while preserving structural rigidity and a glossy finish.
