Vehicle Data Setting System Auxiliary Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle data setting systems require complex and costly rewiring and attachment of new boards when changing vehicle specifications, such as from a typical van to a specially-equipped vehicle like an ambulance, due to the need for additional signal wiring.
Innovation Solution
A vehicle data setting system with standard and auxiliary connection terminals, an input unit for receiving output setting instructions, and a controller to control data output to both types of terminals, allowing easy modification of output signals without requiring new wiring or board attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new boards and wiring are added to change vehicle specifications, then the vehicle can support specially-equipped functions, but the work complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a connector that can serve multiple functions: it works as a standard connector for regular vehicles and as an auxiliary connector for specially-equipped vehicles through software configuration. The same physical connector structure supports both standard and auxiliary output terminals, eliminating the need for different hardware configurations and reducing wiring complexity while maintaining specification adaptability.
2Adaptability or versatility
If new boards are attached to add circuit parts, then the output terminals can be changed, but the labor and cost increase
Solution Approach 1:
The patent uses copying by creating a virtual representation of additional output terminals through software rather than physical duplication. The control unit simulates auxiliary output terminals in software, allowing the system to behave as if additional physical terminals exist without actually attaching new hardware boards. This dramatically reduces manufacturing complexity while maintaining terminal configurability.
3Adaptability or versatility
If rewiring work is performed to add signal wiring, then the vehicle can support additional functions, but the labor and time increase
Solution Approach 1:
The patent applies dynamics by making the connector configuration changeable through software rather than being fixed by physical wiring. The system can dynamically reconfigure which terminals function as standard outputs and which function as auxiliary outputs based on software settings, allowing rapid adaptation to different vehicle specifications without time-consuming rewiring work.
4Stability of the object's composition
If the chassis is designed with predetermined connectors, then the vehicle structure is stable, but adding signal wiring requires complex modifications
Solution Approach 1:
The patent resolves the contradiction by adding a software configuration dimension to the physical connector structure. While the physical chassis and connector remain stable and predetermined, the functional configuration of the connectors can be changed through software parameters. This creates a separation between the stable physical structure and the flexible logical configuration, allowing both structure stability and wiring flexibility to coexist.

AI summary
A vehicle data setting system is provided with auxiliary connection terminals as standard equipment in addition to connection terminals normally used. When an output setting instruction is inputted to the vehicle data setting system from a failure diagnosis tool, output data to be outputted from the connection terminals are changed to desired data by control of a CPU.
