Support structure for supporting a cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support structures for cables lack effective retention mechanisms, leading to inadvertent movement and wear, particularly in partially bent configurations, which can result in fatigue and reduced longevity.
Innovation Solution
A support structure with a body portion extending circumferentially about an axis, featuring retention structures that project from the walls to securely hold the cable in place, providing a snug fit and reducing movement, while allowing for flexibility and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support structure is designed to hold a cable, then the cable is supported, but the cable can still move inadvertently causing wear and fatigue
Solution Approach 1:
The support structure is divided into multiple walls (first wall, second wall, third wall) that collectively form the opening to receive the cable. This segmentation allows each wall to contribute to cable retention while maintaining structural integrity.
Solution Approach 2:
A retention structure acts as an intermediary element between the support structure body and the cable. This retention structure projects into the opening to directly engage with and hold the cable, preventing inadvertent movement while allowing the main body to maintain its structural form.
2Reliability
If a retention mechanism is added to the support structure, then cable retention is improved, but the device complexity increases
Solution Approach 1:
The retention structure is merged with the support structure body, forming an integrated assembly. The retention structure is coupled to the first wall and extends parallel to the third wall, combining the support and retention functions into a single unified structure rather than separate components.
Solution Approach 2:
The support structure body serves multiple functions: it provides the opening to receive the cable, supports the retention structure, and the retention structure itself provides both structural support and cable retention. This multi-functionality reduces the need for additional separate components.
3Duration of action of stationary object
If the support structure is designed to meet bend radius requirements, then cable longevity is improved, but handling and installation become more difficult
Solution Approach 1:
The support structure body extends circumferentially about an axis, creating a curved or circular geometry that naturally accommodates cable bends. This curved configuration helps the cable meet bend radius requirements, preventing sharp folds that would cause fatigue, while the open structure allows easy cable insertion and handling.

AI summary
A support structure (100, 400) is provided for supporting a loop of a dead-end termination (102). The support structure includes a body portion extending circumferentially about an axis. The body portion includes a first wall, a second wall extending substantially parallel to the first wall, and a third wall coupled between the first wall and the second wall. The first wall, the second wall, and the third wall define an opening extending along a circumferential length of the body portion. The body portion receives the termination within the opening. The support structure comprises a first retention structure (230, 520) coupled to the first wall and a second retention structure (232 or 234, 522) coupled to the second wall. The retention structure retain the termination within the opening.
