Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boat propulsion apparatuses face challenges in easy maintenance and management, especially when engines are replaced or new functions are added, and there is a risk of mischievous operation or theft.
Innovation Solution
The implementation of an engine control device with dual ID storage and network connectivity for authentication, allowing secure remote control and maintenance, eliminating the need for manual ID setting and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual ID setting is implemented for authentication, then security against theft and mischievous operation is improved, but ease of operation deteriorates due to complex ID input and setting procedures
Solution Approach 1:
The system automatically performs ID authentication by having the engine control device autonomously acquire and store the ID from the remote control device when connected via network. This eliminates the need for manual ID input and setting, while maintaining secure authentication through automatic comparison of stored IDs with transmitted IDs.
2Adaptability or versatility
If engine replacement or new function addition is allowed, then adaptability is improved, but maintenance and management complexity increases
Solution Approach 1:
The system pre-stores authentication IDs in the engine control device before engine replacement or function addition occurs. When the engine is replaced or new functions are added, the system automatically performs authentication using the pre-stored ID, eliminating the need for complex reconfiguration or manual ID re-entry, thus simplifying maintenance and management while maintaining adaptability.
3Ease of operation
If automatic ID acquisition is implemented, then ease of operation is improved, but security may deteriorate if authentication is not properly verified
Solution Approach 1:
The system implements a feedback mechanism where the engine control device automatically transmits the acquired ID to a predetermined device for verification. Based on the verification result, the system provides feedback to either enable or disable remote control device operation. This ensures that automatic ID acquisition maintains security through proper authentication verification while preserving ease of operation.

AI summary
In a boat propulsion apparatus including an engine control device for controlling operation of an engine, the engine control device includes a first ID storage and a second ID storage, a first ID is stored in the first ID storage beforehand, and the engine control device is communicably connected to a controller of a remote control device over a network. A signal containing a second ID is received from the controller when the engine control device and the controller are connected to the network for the first time and is stored in the second ID storage. Thus, maintenance and management of the engine are easy, and also it is possible to prevent a mischievous operation or theft of the boat propulsion apparatus.
