Loop-Structured Adhesive Tape for Easier Cable Harness Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes are difficult to handle and require frequent changes during wrapping operations, especially in confined spaces, limiting their efficiency in applications like automotive cable harness wrapping.
Innovation Solution
The adhesive tape features a textile carrier with knitting or sewing threads forming adjacent connecting loops that allow easy unwinding by passing through each other, enabling efficient winding and unwinding without overlapping, thus reducing the need for frequent changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive tape is wound onto a roll in conventional manner, then it can be stored and transported efficiently, but it becomes difficult to handle and requires frequent changes during wrapping operations
Solution Approach 1:
The patent applies the dynamics principle by creating a tape structure where the loop chains can dynamically expand and contract. The loops are formed such that they can be easily pulled apart during unwinding, allowing the tape to be pulled off the roll in long continuous sections rather than requiring frequent roll changes. This dynamic structure enables the tape to adapt to handling requirements during wrapping operations.
Solution Approach 2:
The patent segments the tape structure into multiple loop chains running parallel to each other. Each loop chain consists of numerous adjacent loops that can be independently manipulated. This segmentation allows the tape to be easily grasped and pulled from the roll by catching on the loop structure, facilitating smooth unwinding and reducing handling difficulty during wrapping operations.
2Ease of operation
If adhesive tape uses conventional backing material structure, then it provides adequate adhesive support, but it creates friction between layers making unwinding difficult
Solution Approach 1:
The patent uses a nonwoven fabric backing that functions as a flexible structure with inherent loop formations. This flexible structure allows the tape layers to slide past each other during unwinding without excessive friction, while still maintaining adequate adhesive support. The loop structure of the nonwoven fabric provides a balance between layer flexibility for easy unwinding and structural integrity for adhesive support.
3Stability of the object's composition
If adhesive tape is made from nonwoven fabric with seams, then it provides structural integrity, but the surface structure creates friction that impedes smooth unwinding
Solution Approach 1:
The patent changes the structural parameters of the nonwoven fabric by forming loop chains with specific geometries. The loops are configured with openings facing one direction and bases facing the opposite direction, creating a directional structure that reduces friction during unwinding. This parameter change maintains the structural integrity of the nonwoven fabric while significantly improving unwinding smoothness by allowing layers to slide more easily over each other.
