Wire Harness Protector Cover Protrusion for Tape Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness routing methods require lifting the harness to prevent protruding pieces from being wound with protective tape, leading to potential wire deviation or bundle collapse during tape application.
Innovation Solution
A wire harness protector with a protruding piece positioned on the cover side, allowing tape winding without lifting the harness, and a binding band is used to secure the tape and harness to the protruding piece, ensuring close contact between the cover and harness for impact protection and easy water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protruding piece is provided on the protector base and the protective tape is wound around the wire harness, then the wire harness can be protected from side slip and hitting, but the protruding piece may be wound together with the tape requiring the wire harness to be lifted
Solution Approach 1:
The protruding piece is extracted from the protector base and relocated to the cover. This separation allows the protective tape to be wound around the wire harness without encountering the protruding piece, eliminating the need to lift the wire harness during tape winding while maintaining the protection function when the cover is assembled
Solution Approach 2:
The protective tape is wound around the wire harness before the cover with the protruding piece is assembled. This preliminary action allows the tape to be applied smoothly without obstruction, and the protruding piece subsequently provides protection without interfering with the already-applied tape
2Ease of manufacture
If the wire harness is lifted to prevent the protruding piece from being wound with the tape, then the tape winding can be completed, but the position of electric wires may be deviated or the electric wire bundle may be collapsed
Solution Approach 1:
By extracting the protruding piece from the protector base and placing it on the cover, the obstruction to tape winding is removed. The wire harness can remain in its original position during tape winding, preventing wire position deviation and bundle collapse while still allowing complete tape application
3Reliability
If the cover is put on the protector base, then the wire harness is protected from impact, but water may accumulate around the wire harness
Solution Approach 1:
The wire harness is positioned to extend in the longitudinal direction of the protector base, creating a floating state that utilizes the longitudinal dimension for water discharge. This orientation allows water to drain along the length of the protector base while the cover provides impact protection from above

AI summary
A wire harness routing method is provided. A wire harness is routed on a protector base. A protective tape is wound around an outer periphery of the wire harness at a position outside an end portion of the protector base in a longitudinal direction. A cover is put on the protector base under the above state. The wire harness is fixed to, by winding a binding band at a position where the tape is wound, a wire harness-fixed protruding piece protruding outward in the longitudinal direction from an end portion of the cover in the longitudinal direction.
