Wire Harness Assembly With Pull-Out Connector Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harness assemblies have low versatility due to the fixed arrangement of connectors with respect to specific target members, requiring separate assemblies for different mating connectors positions.
Innovation Solution
A wire harness assembly with a pull-out portion that allows the electric wire to be pulled out from the assembly member, enabling the connector's position to be adjusted, thereby accommodating varying mating connector positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector arrangement position is fixed according to a specific target member, then the assembly is reliable for that specific target member, but the versatility is reduced when assembling to different target members
Solution Approach 1:
The assembly member is designed with a pull-out portion that enables dynamic adjustment of the connector's position. The electric wire can be pulled out through the pull-out portion to reposition the connector from a first position to a second position, allowing the same assembly to adapt to different target members while maintaining reliable connector fitting
Solution Approach 2:
The connector position parameter can be changed by pulling out the electric wire through the pull-out portion. This allows the connector to be positioned at different locations relative to the assembly member, enabling the same wire harness assembly to be used with different target members that have mating connectors at different positions
2Reliability
If separate wire harness assemblies are created for each target member, then the connector fits reliably, but the device complexity and manufacturing cost increase
Solution Approach 1:
A single wire harness assembly design serves multiple functions by accommodating different target members. The pull-out portion mechanism allows the same assembly to be configured for different mating connector positions, eliminating the need to manufacture separate assemblies for each target member and reducing device complexity

AI summary
A wire harness assembly includes: a wire harness including an electric wire and a connector electrically connected to an end of the electric wire; and an assembly member in which the wire harness is arranged. The connector is arranged to be exposed to an outside of the assembly member. The assembly member has a pull-out portion configured to pull out the electric wire arranged inside the assembly member to the outside of the assembly member to change an arrangement position of the connector.
