Ribbon Cable Wrapping Structure for Stable Double-Sided Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ribbon cables have an unstable fixing structure, with cables easily falling off and becoming loose due to exposed hot melt adhesive on one side, which is prone to environmental failure.
Innovation Solution
A ribbon cable design featuring multiple cable groups arranged side by side with a wrapping film wound at an inclined angle, providing a double-sided fixing structure with hot melt adhesive on both sides, reducing exposure to the environment and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a covering film with hot melt adhesive is provided on one side of the cable groups, then the cable fixing structure is simple, but the fixing stability is poor and cables easily fall off
Solution Approach 1:
The patent transitions from a single-sided adhesive structure to a double-sided adhesive structure by wrapping the covering film around both sides of the cable groups. This dimensional change from one side to two sides provides balanced fixing force and prevents cable loosening, resolving the contradiction between structural simplicity and fixing stability.
Solution Approach 2:
The patent introduces asymmetric wrapping where the covering film is wrapped at different positions on opposite sides of the cable groups, creating an asymmetric double-sided fixing structure. This asymmetric design provides more reliable cable positioning and prevents loosening while maintaining manufacturing simplicity.
2Ease of manufacture
If the hot melt adhesive on the covering film is exposed to air, then the manufacturing process is simple, but the adhesive is easily affected by external environment and prone to failure
Solution Approach 1:
The patent uses the covering film as a flexible shell that wraps around the cable groups, creating a closed or semi-closed structure that protects the hot melt adhesive from direct exposure to air. This thin film encapsulation shields the adhesive from environmental factors while maintaining the simplicity of the manufacturing process.
Solution Approach 2:
By transitioning to a double-sided wrapping structure, the patent creates a more enclosed environment for the adhesive on both sides, reducing its exposure to air and external environment. This dimensional change improves adhesive reliability without significantly complicating the manufacturing process.
3Device complexity
If the covering film is only attached to one side of the cable groups, then the structure is simple, but the cable fixing is unstable and prone to loosening
Solution Approach 1:
The patent applies the covering film to both sides of the cable groups through wrapping, transitioning from a single-sided to a double-sided fixing structure. This dimensional change provides balanced fixing force from both sides, significantly improving cable fixing stability while maintaining reasonable structural complexity.
Solution Approach 2:
The double-sided wrapping structure creates counterbalancing fixing forces on opposite sides of the cable groups. The adhesive on one side compensates for any potential loosening on the other side, providing stable cable positioning and preventing loosening through this counterweight effect.

AI summary
A ribbon cable includes a plurality of cable groups arranged side by side in a width direction of the ribbon cable and a wrapping film continuously wound on an outer side of the cable groups in a multi-turn wrapping manner at an inclined angle with respect to the width direction. There is a gap between every adjacent pair of cable groups.
