Serpentine Cable Retention Grip for Secure Pulling Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems lack efficient and flexible solutions for temporarily attaching gripping devices to cables, particularly for varying diameters and materials, to withstand pulling forces during installation or conduit passage.
Innovation Solution
A flexible cable retention grip with a serpentine shape and v-shaped teeth, secured by cable ties, which can be easily wrapped around cables and provides increased contact surface area and holding force, accommodating cables of different diameters and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a solid strip of material is used for the retention grip, then the structural strength is maintained, but the flexibility and adaptability to different cable diameters are reduced
Solution Approach 1:
The retention grip is divided into multiple segments separated by slots, allowing the structure to flex and adapt to different cable diameters while maintaining overall structural integrity. The slots enable the grip to conform to various cable sizes without compromising its strength.
Solution Approach 2:
The retention grip is designed as a flexible strip with slots that allow it to bend and adapt to different cable diameters. This flexible structure can be wrapped around cables of varying sizes while maintaining sufficient structural strength to hold the cable securely.
2Force
If the grip surface has a simple flat design, then the manufacturing complexity is reduced, but the contact surface area and holding force are insufficient
Solution Approach 1:
The grip surface features localized V-shaped teeth that concentrate holding force at specific contact points. This local quality enhancement provides increased friction and holding force without requiring the entire surface to be complex, thus maintaining manufacturing feasibility while improving performance.
3Adaptability or versatility
If the slots extend completely through the width of the main body, then the flexibility is maximized, but the structural integrity and resistance to pulling forces are reduced
Solution Approach 1:
The slots extend partially through the width of the main body rather than completely through. This partial penetration provides sufficient flexibility to adapt to different cable diameters while maintaining enough structural integrity to resist pulling forces during cable installation.
4Reliability
If a complex securing mechanism is used to attach the retention grip to the cable, then the holding security is improved, but the ease of installation and removal is reduced
Solution Approach 1:
The retention grip is designed to be self-securing through friction and the gripping action of the V-shaped teeth on the cable jacket. This eliminates the need for complex fastening mechanisms, allowing for easy installation by simply wrapping the grip around the cable and securing it with a tie, while maintaining reliable holding security.
