Wire Harness Fixing Structure With Guide Groove Cable Tie Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cable tie fixing structure for electric wires in automobiles is inefficient due to tilting and positional variations of the cable tie, which hampers the collective fixing of multiple wires.
Innovation Solution
A harness component with a guide groove system that accommodates the band-shaped portion of the cable tie, allowing it to be easily attached and fixed, featuring a first wall portion, a second wall portion, and a bottom portion that supports the second wall portion away from the first wall portion, ensuring the cable tie is securely positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable tie is locked to the cable tie holding portion only by inserting the band-shaped portion into the band insertion hole, then the fixing structure is simple, but the cable tie may tilt or the position of the head portion may vary during the fixing task
Solution Approach 1:
A guide groove is introduced as an intermediary element between the cable tie and the holding portion. The guide groove receives and guides the band-shaped portion of the cable tie, ensuring proper positioning and preventing tilting during the fixing task. This mediator structure maintains simplicity while improving position accuracy.
Solution Approach 2:
The guide groove structure allows the cable tie to self-position and self-align during insertion. The geometric constraints of the guide groove automatically guide the band-shaped portion into the correct position without requiring additional positioning mechanisms or complex alignment procedures.
2Device complexity
If the cable tie is locked only by inserting the band-shaped portion into the band insertion hole, then the fixing mechanism is simple, but the efficiency of collectively fixing multiple electric wires is reduced
Solution Approach 1:
The guide groove acts as a mediator that facilitates the efficient fixing of multiple wires. By providing a guided path for the cable tie, it enables faster and more reliable collective fixing of multiple electric wires, improving productivity without significantly increasing mechanism complexity.
3Device complexity
If no guide structure is provided, then the harness component structure is simple, but the cable tie may tilt or vary in position during the fixing task
Solution Approach 1:
The guide groove serves as a stabilizing intermediary structure that prevents cable tie tilting and position variation. It provides geometric constraints that maintain cable tie stability during the fixing task while adding minimal structural complexity to the harness component.
