Wire Harness Protector With Segmented Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harness protectors face inefficiencies in attaching and removing protectors from electric wires due to the need for winding tapes and complex detachment procedures, which hinder work efficiency and complicate the process.
Innovation Solution
A wire harness protector design featuring a main body with a three-dimensional shape and multiple covers that allow relative displacement, eliminating the need for tapes and simplifying attachment and removal by covering end and middle portions, with lock projections to secure corrugated tubes and prevent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tapes are wound around the protector body to fix electric wires, then the electric wires are securely fixed to the protector body, but the work efficiency of attaching and removing the protector decreases
Solution Approach 1:
The cover is divided into multiple detachable clips that can be independently attached and detached from the protector body. This segmentation allows the cover to be quickly installed and removed without winding tapes, thereby improving work efficiency while maintaining secure fixation of the electric wires through the clip structures.
Solution Approach 2:
The fixing function is extracted from the tape-winding process and integrated into the clip structure itself. The clips are designed with inherent fixing capabilities through their engagement with the protector body, eliminating the need for separate tapes and simplifying the attachment process.
2Reliability
If tapes are wound around the protector body to fix electric wires, then the electric wires are securely fixed, but the process of removing the protector becomes difficult and time-consuming
Solution Approach 1:
The cover is segmented into multiple detachable clips that can be independently removed from the protector body. This segmentation enables the cover to be quickly taken off by simply detaching the clips without having to unwind tapes, thereby improving ease of removal while maintaining secure fixation during use.
Solution Approach 2:
The clips are designed with dynamic attachment and detachment capabilities, allowing them to be easily engaged and disengaged from the protector body. This dynamic design enables quick removal of the cover by simply releasing the clips, eliminating the time-consuming process of unwinding tapes.
3Shape
If the protector body has a three-dimensional shape, then it can effectively protect and route wire harnesses, but the electric wires tend to separate from the protector body
Solution Approach 1:
The clips are designed with local quality variations to match the three-dimensional shape of the protector body. Different portions of the clips have different engagement structures that adapt to the specific geometry of the protector body at various locations, ensuring secure wire attachment throughout the complex three-dimensional structure.
Solution Approach 2:
Instead of trying to force the electric wires to conform to the three-dimensional shape of the protector body, the clips are designed to adapt to the existing shape. The clips engage with the protector body's three-dimensional features and provide the necessary constraint forces to prevent wire separation, reversing the approach from wire-to-protector fitting to protector-to-wire securing.

AI summary
A wire harness protector includes: a main body defining a passage; and a plurality of covers. The main body defines the passage by a groove recessed in an attaching direction to allow the wire harness (WH) to be attached to the main body. The plurality of the covers includes a first cover covering an opening of the groove near one end, a second cover covering the opening near the other end, and a third cover connected to one of the first cover and the second cover while allowing its relative displacement to the one of the first cover and the second cover and covering the opening near the middle portion.
