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

VSEngineering 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

Engineering Contradiction:
Improvecable retentionVSAvoidcable wear and fatigue
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a retention mechanism is added to the support structure, then cable retention is improved, but the device complexity increases

Engineering Contradiction:
Improvecable retentionVSAvoidsupport structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvecable longevityVSAvoidhandling and installation
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

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.

Inventive Principle:
Principle #14Spheroidality (Curvature)

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.
