Wire Harness Tape Wrapping With Gaps for Higher Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness protective solutions require operations to switch out binding adhesive tape, which is undesirable for high protective capability applications.
Innovation Solution
A wire harness with a tape-wrapping protective portion formed by wrapping adhesive tape to create gaps around the wire, increasing the outer diameter and preventing the edge from reaching the wire, thus providing high protective capabilities while minimizing the need to switch out binding adhesive tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective member different from adhesive tape is attached to provide high protective capabilities, then protection capability is improved, but operation complexity increases due to switching out binding adhesive tape
Solution Approach 1:
The patent combines the protective member and binding adhesive tape into a single integrated structure. The binding adhesive tape is attached directly to the protective member, eliminating the need for separate attachment operations and switching procedures, thus resolving the contradiction between high protective capability and operational simplicity
Solution Approach 2:
The binding adhesive tape serves dual functions: it binds the protective member to the wire harness and simultaneously provides protective coverage. This multi-functionality eliminates the need for separate protective members and reduces operational complexity while maintaining high protective capabilities
2Reliability
If adhesive tape is wrapped tightly to prevent exposure, then protection is improved, but adhesive tape may adhere to the wire causing damage
Solution Approach 1:
The protective member acts as an intermediary barrier between the adhesive tape and the wire. The adhesive tape is attached to the protective member rather than directly to the wire, preventing adhesive damage to the wire while maintaining tight wrapping for optimal protection
Solution Approach 2:
The protective member provides a flexible protective shell that allows the adhesive tape to wrap tightly around the wire harness without the adhesive contacting the wire. This thin film structure maintains protection capability while eliminating the harmful adhesive-wire contact
