Wire Harness Path Restrictor Attachment for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harnesses face challenges in maintaining the positional accuracy of path restricting members, which can lead to misalignment and reduced durability due to vibrations and external factors during vehicle travel.
Innovation Solution
The wire harness design incorporates a path restricting member with a first main body and a first insertion port, along with an attaching member featuring a cover and engaging portions, which securely attach to the exterior member, preventing rotation and displacement, thereby enhancing positional accuracy and assembly workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a path restricting member is attached to an exterior member without additional securing mechanisms, then the device complexity is reduced, but the positional accuracy and stability of the path restricting member deteriorates due to vibrations and external factors during vehicle travel
Solution Approach 1:
The attaching member is divided into distinct functional segments: a body portion that interfaces with the path restricting member and an engaging portion that interfaces with the exterior member. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity of the attachment mechanism.
Solution Approach 2:
The engaging portion is inserted into a corresponding recess or slot in the exterior member, creating a nested structure where the attaching member fits within the exterior member's profile. This nesting approach secures the path restricting member without requiring external fasteners or complex mounting hardware.
2Manufacturing precision
If the path restricting member is securely attached to prevent displacement, then the positional accuracy is improved, but the ease of manufacture and assembly may deteriorate due to additional securing mechanisms
Solution Approach 1:
The engaging portion is pre-formed as an integral part of the attaching member, ready for insertion into the exterior member during assembly. This preliminary preparation eliminates the need for additional fastening steps or complex assembly operations, maintaining ease of manufacture while ensuring secure attachment.
Solution Approach 2:
The engaging portion and its corresponding recess in the exterior member are designed to self-align and self-secure during assembly. The geometry of the engaging portion automatically guides it into the correct position within the recess, eliminating the need for precise manual alignment or additional securing operations.
3Ease of operation
If the path restricting member is made detachable for assembly purposes, then the ease of operation is improved, but the reliability and durability deteriorate due to potential detachment during vehicle travel
Solution Approach 1:
The engaging portion is designed with an asymmetric geometry that allows easy insertion in one direction but prevents removal in the opposite direction. This asymmetric design provides simple assembly while ensuring reliable, vibration-resistant attachment during vehicle operation, as the engaging portion cannot back out or detach under normal operating conditions.
