Cable Tape Member Segmentation for Clean Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable and wire harness technologies face difficulties in efficiently removing the sheath and tape member during end processing, as the blade often fails to cut through the tape member, leading to poor workability and potential fuzzing of fibers.
Innovation Solution
A cable with a tape member composed of entangled fibers featuring intentionally formed holes or slits, which improves tearability and flexibility, allowing for easier removal of the tape member and sheath during end processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the blade does not reach the tape member during end processing, then the sheath can be removed, but the tape member becomes difficult to remove
Solution Approach 1:
The tape member is segmented by forming holes or slits through it, dividing the continuous tape into sections that can be easily separated. This segmentation allows the tape member to be readily removed from the cable assembly without requiring the blade to cut through the entire length, solving the problem of difficult removal when the blade doesn't reach the tape member.
Solution Approach 2:
The holes or slits are formed in the tape member during manufacturing as a preliminary action, creating pre-weakened points that facilitate subsequent removal. This preliminary structuring of the tape member with holes/slits enables easy tearing and removal during end processing, eliminating the need for precise blade depth control.
2Ease of manufacture
If the blade cuts through the tape member, then the tape member can be removed, but fiber fuzzing occurs
Solution Approach 1:
By forming holes or slits in the tape member, the continuous fiber structure is divided into discrete sections. During removal, the tape tears cleanly along these pre-formed openings rather than being cut through, preventing fiber fuzzing while still enabling easy removal of the tape member from the cable assembly.
Solution Approach 2:
The potential harm of cutting through the tape member, which causes fiber fuzzing, is converted into a benefit by pre-forming holes or slits. These openings provide controlled separation points that guide the tearing process, transforming what would be a damaging cut into a clean, fuzz-free separation that maintains manufacturing precision.
3Stability of the object's composition
If the tape member is made of dense nonwoven fabric, then the cable structure is stable, but the tape member is difficult to remove
Solution Approach 1:
Holes or slits are formed in the dense nonwoven fabric tape member, creating segmentation that maintains the overall structural stability of the cable during use while providing easy separation points for removal. The dense fabric maintains stability, and the holes provide removal facilitation without compromising either property.
Solution Approach 2:
The tape member has non-uniform local quality: dense nonwoven fabric in most areas for structural stability, and localized holes or slits for easy removal. This local differentiation allows the tape to simultaneously provide cable stability during service and facilitate easy removal during end processing by tearing at the hole locations.
