Wire Harness Protector Layout for Flexible Connector Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness routing structures do not adequately facilitate the fitting of connectors to mating connectors, particularly when the relative positions of components vary, leading to reduced workability in assembly processes.
Innovation Solution
A routing structure for a wire harness that includes a protector accommodating a first and second exposed portion of the wire harness, allowing these portions to be extended side by side and enabling the distance between them to be adjusted, thereby facilitating flexible routing and improved fitting workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wire harness is protected by a rigid protector with fixed routing, then the wire harness is protected from damage, but the workability of fitting the connector to the mating connector deteriorates when component positions vary
Solution Approach 1:
The patent applies the dynamics principle by making the protector movable rather than fixed. The protector can shift its position along the wire harness to accommodate variations in component positions during assembly, allowing the first and second exposed portions to be positioned at appropriate locations while maintaining wire harness protection throughout the fitting process
2Stability of the object's composition
If the routing path of the wire harness is fixed, then the structure is simple and stable, but the adaptability to different component positions deteriorates
Solution Approach 1:
The routing structure transitions from a fixed to a dynamic configuration. The protector's ability to move along the wire harness enables the routing path to adapt to different component positions while maintaining overall structural stability through the controlled movement mechanism
3Manufacturing precision
If the distance between the first exposed portion and the second exposed portion is fixed, then the manufacturing precision is maintained, but the ease of operation deteriorates when component positions vary
Solution Approach 1:
The distance between the first and second exposed portions becomes a dynamic parameter rather than a fixed value. The protector's movement capability allows this distance to be adjusted during assembly to match the actual positions of the bus bar and connector, while the protector itself maintains precise positioning through its movement mechanism

AI summary
A routing structure of a wire harness includes a wire harness including a detection wire connecting a bus bar and a connector; and a protector; in which the wire harness includes a protecting portion protected by the protector, a first exposed portion, and a second exposed portion, the first exposed portion projects out from the protector toward the bus bar, the second exposed portion projects out from the protector toward the connector, and the protector is configured to accommodate the protecting portion so as to extend the first exposed portion and the second exposed portion side by side, and to change a distance between the first exposed portion and the second exposed portion.
