Multi-Cable Hanger Structure for Spaced Solar Racking Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable hangers are inadequate for managing the increased number of cables in utility-scale solar plants, particularly in solar panel racking systems, as they fail to provide effective cable management and support.
Innovation Solution
A hanger device with multiple cable supports featuring parallel and lateral shape retention sidewalls, radiused wire engagement surfaces, and J-shaped hooks that engage the carrier cable for secure three-point suspension, allowing for horizontal and spaced arrangement of cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable hangers are used, then installation is simple, but cable management effectiveness is insufficient for utility-scale solar plants
Solution Approach 1:
The hanger body is divided into multiple cable support features (first cable support feature, second cable support feature, etc.), each capable of independently holding cables. This segmentation allows the hanger to manage multiple cables effectively while maintaining a relatively simple overall structure.
Solution Approach 2:
The hanger is designed with multiple cable support features that can accommodate various cable types and configurations. The opposing hooks can engage with carrier cables in different orientations, and the cable support features can hold cables in horizontal, vertical, or angled arrangements, providing universal cable management capability.
2Stability of the object's composition
If multiple cables are suspended closely together, then space is utilized efficiently, but cable stability and organization deteriorate
Solution Approach 1:
Each cable support feature is designed with specific local characteristics - the lateral shape retention sidewalls create localized confinement zones for individual cables, while the opposing hooks provide localized engagement points on the carrier cable. This local quality control ensures each cable is stabilized independently, preventing cable entanglement and improving overall cable organization.

AI summary
A hanger device comprises a plurality of cable supports, each comprising a parallel sidewall and a lateral shape retention sidewall where the parallel sidewalls and the lateral shape retention sidewall are separated by a wire engagement surface for holding one or more of the plurality of cables, where each of the lateral shape retention sidewalls includes a hook that comprises first and second hook sidewalls and a radiused surface that separates the first and second hook sidewalls, where each of the hooks opens in an exterior opposing direction; and a hanger surface that separates the parallel sidewalls, where the hanger device is hung on the hanger carrier by placing the hanger surface on the hanger carrier and the lateral shape retention sidewalls are pressed inwardly towards the parallel sidewalls and about the engagement surfaces so both hooks opposingly engage the cable.
