Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity and number of circuit assemblies and wire harnesses in vehicles, particularly in electric and hybrid vehicles, lead to reduced workability and space efficiency during assembly, as conventional connector systems require more steps and space for connection.
Innovation Solution
A wire harness connecting structure that integrates two electrical wire-side connection terminals from separate wires into a shared connector housing, allowing a single harness end connector to connect to both circuit assemblies, reducing the number of parts and improving space efficiency, while also canceling out magnetic fields and noise through opposing current directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connectors are used for each circuit assembly, then reliable electrical connection is achieved, but the number of parts and connection steps increases
Solution Approach 1:
The patent combines two separate connectors into a single integrated connector that simultaneously connects to both circuit assemblies. The connector housing contains two connection terminals that can engage with both circuit assemblies in one connection action, reducing the number of parts and assembly steps while maintaining reliable electrical connections.
Solution Approach 2:
The single connector is designed with multi-functional capability to connect to multiple circuit assemblies simultaneously. The connector housing and connection terminals are configured to establish electrical connections with both first and second circuit assemblies through a unified structure, eliminating the need for separate dedicated connectors.
2Area of stationary object
If circuit assemblies are arranged densely to save space, then space efficiency improves, but the number of connection steps and required space for connectors increases
Solution Approach 1:
By merging two separate connectors into one integrated connector, the patent reduces the total space required for connector placement and simplifies the connection process. This allows circuit assemblies to be arranged more densely without proportionally increasing the space needed for connection components.
3Reliability
If multiple wire harnesses with separate connectors are used, then electrical connectivity is ensured, but workability and assembly efficiency degrade
Solution Approach 1:
The patent merges multiple connection operations into a single assembly step by using one integrated connector to connect to both circuit assemblies simultaneously. This reduces the number of assembly steps and improves workability while ensuring reliable electrical connectivity through the multi-terminal connector design.
4Reliability
If separate connectors are used for each wire end, then proper electrical connection is achieved, but the number of parts increases
Solution Approach 1:
The patent combines two separate connectors into one integrated connector housing that contains two connection terminals. This single connector replaces what would traditionally require two separate connectors, reducing the quantity of parts while maintaining proper electrical connections to both circuit assemblies.
