Keyless Controller Identification Number Assignment for Outboard Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification number setting systems for outboard motors require complex control of engine control modules (ECMs), making it difficult to set identification numbers for multiple motors attached to a ship without intricate control processes.
Innovation Solution
A keyless controller performs an authentication process and sets identification numbers in engine control modules during initial registration, eliminating the need for complex ECM control and allowing identification number setting based on motor arrangement and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ECM of each outboard motor sets identification numbers between the corresponding outboard motor and other outboard motors, then the identification number setting function can be realized, but the control of ECMs becomes complicated
Solution Approach 1:
The patent introduces a dedicated identification number setting device as an intermediary component that centralizes the identification number setting function. This device communicates with multiple ECMs to assign identification numbers, thereby eliminating the need for each ECM to independently perform complex setting operations. The intermediary device manages the identification number allocation process, simplifying ECM control while maintaining reliable identification number setting functionality.
2Ease of operation
If identification numbers are set in individual outboard motors, then appropriate control of individual engines can be achieved, but complex control processes are required for multiple motors
Solution Approach 1:
The identification number setting device serves as a mediator that handles the complex control processes for assigning identification numbers to multiple outboard motors. By centralizing this function, individual ECMs can focus on controlling their respective engines using simple identification numbers, improving ease of operation while the intermediary manages the complexity of coordinating multiple motors.
3Reliability
If the ECM performs authentication and identification number setting, then security and identification are ensured, but the control program becomes complex
Solution Approach 1:
The patent introduces a dedicated identification number setting device as an intermediary that centralizes authentication and identification number setting functions. This device handles the complex control programs for authentication and ID assignment, while ECMs perform simpler authentication based on assigned identification numbers. This separation maintains security and reliable authentication while reducing the complexity of control programs in individual ECMs.
