Outboard Motor Display Device with Dual Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for vehicles, such as those described in Patent Document 1, are limited in usability and functionality as they are only designed for vehicle-mounted use and lack versatility for service and inspection purposes.
Innovation Solution
A display device for outboard motors that includes a storage unit for unique information, offering both a gauge mode for displaying operating states and a service tool mode for displaying unique information, with the ability to switch between modes, allowing for enhanced usability and functionality, including remote diagnostic capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is designed only for vehicle-mounted use, then the device structure can be simplified, but the usability and functionality are limited
Solution Approach 1:
The display device is designed to perform multiple functions: it serves as a gauge display when mounted to the vehicle and as a service tool when detached for repair operations. The device includes a processor that can execute different modes (gauge mode and service tool mode) depending on how it is connected, allowing one physical device to fulfill multiple roles without requiring separate specialized devices for each function.
2Adaptability or versatility
If the display device includes both gauge mode and service tool mode, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The display device dynamically switches between different operational modes (gauge mode and service tool mode) based on connection status and user input. The processor can change its behavior and display output according to the current operating context, allowing the same hardware to adapt its functionality rather than requiring separate dedicated systems for each mode.
3Adaptability or versatility
If the display device stores unique information locally, then the service tool functionality is improved, but the storage requirements increase
Solution Approach 1:
The display device pre-stores unique identification information and diagnostic data locally in its memory before service operations are needed. This preliminary storage of essential information allows the device to function independently as a service tool without requiring immediate external data sources, enabling rapid diagnostic operations while minimizing the need for large external storage systems.

AI summary
A display device for an outboard motor includes a storage device storing unique information of the outboard motor. The display device for the outboard motor has a gauge mode and a service tool mode as display modes. By mounting the display device for the outboard motor to a specific boat, both an operating state of the outboard motor and the unique information of the outboard motor are displayable in the gauge mode. Only the unique information of the outboard motor is displayable in the service tool mode. The display modes are configured to be switched between the gauge mode and the service tool mode.
