Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boat designs with remote control units for electric propulsion suffer from unreliable signal transmission due to multiple connection points in cables, leading to increased risks of incorrect connections and breakages.
Innovation Solution
Direct connections between the remote control unit ECU and the propulsion unit ECU via DBW CAN cables, eliminating intermediate connectors and enhancing signal stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple connection points are provided along the cable between remote control unit and propulsion unit, then the cable is more flexible and easier to route, but signal exchange stability deteriorates and reliability is reduced
Solution Approach 1:
The patent removes intermediate connectors from the cable path between remote control unit and propulsion unit. By extracting these connection points, the system eliminates signal loss and connection instability while maintaining cable flexibility through proper routing paths along the hull.
Solution Approach 2:
The patent merges the cable connection into a direct single-point connection between remote control unit and propulsion unit, eliminating multiple intermediate connectors. This consolidation improves signal stability while the cable is routed along the hull to maintain physical flexibility.
2Ease of operation
If multiple connection points are provided along the cable, then the cable can be routed more flexibly, but the risk of incorrect connections and breakages increases
Solution Approach 1:
The patent extracts intermediate connectors from the cable path, reducing the number of potential failure points. This eliminates risks associated with connector misalignment, loose connections, and contact deterioration while maintaining cable routing flexibility through hull-mounted pathways.
3Reliability
If direct connection is made between remote control unit and propulsion unit, then reliability of signal transmission is improved, but cable routing becomes more complex
Solution Approach 1:
The patent introduces the hull structure as an intermediary pathway for cable routing. The cable is routed along the hull's surface or interior, using the hull as a guide structure. This mediator approach simplifies routing complexity while maintaining direct electrical connection for reliable signal transmission.
4Ease of manufacture
If multiple connectors are used along the cable, then installation flexibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent removes intermediate connectors that would require precise alignment. By extracting these connection points and implementing a direct connection with hull-routed cable, the system reduces manufacturing precision requirements while maintaining installation flexibility through the hull's structural pathways.

AI summary
A boat can be provided with an electrically controlled outboard motor, or other type of propulsion unit, for producing thrust according to an operation of a remote control unit provided in a hull of the boat. The remote control ECU which can output a remote control operation signal can be provided in the remote control unit. An engine ECU which can receive the remote control operation signal and control the outboard motor, can be provided in the outboard motor. The remote control unit and the outboard motor can have respective connectors directly connected to each other via a DBW CAN cable.
