Gangible Cable Support Box Mounting Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable supports for high data transmission cables lack balanced weight distribution, stiffness to resist bending moments, and an efficient cable retaining mechanism, and require additional brackets for ganging multiple supports.
Innovation Solution
A one-piece cable support with a box-shaped mounting assembly, stiffeners, and a cable retaining arrangement that allows even weight distribution and direct ganging without additional brackets, constructed from metal with punched apertures and bent design for increased stiffness and secure cable retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If J-shaped hooks are used to support cable bundles, then cable anchoring is achieved, but the bending moment causes material fatigue and breakage near the anchoring point
Solution Approach 1:
The support device is divided into a mounting assembly portion (for anchoring) and a cable tray portion (for cable support), separated by a wall portion. This segmentation moves the cable support function away from the anchoring point, eliminating the bending moment that causes fatigue in traditional J-hooks.
Solution Approach 2:
The wall portion acts as an intermediary element connecting the mounting assembly to the cable tray. It transfers the load from the cable tray through the wall to the mounting assembly, distributing stress and preventing concentration at the anchoring point.
2Ease of operation
If traditional cable supports are used, then individual cable support is achieved, but additional brackets are required for ganging multiple supports
Solution Approach 1:
The mounting assembly portion and cable tray portion are merged into a single integrated support device. The mounting assembly includes built-in features (receiving tabs, fastening arrangements) that enable direct ganging of multiple supports without requiring separate brackets, reducing the total number of parts.
Solution Approach 2:
The mounting assembly serves multiple functions: it provides structural anchoring, enables ganging of multiple supports through integrated receiving tabs and fastening arrangements, and supports the cable tray portion. This multi-functionality eliminates the need for separate bracket components.
3Reliability
If cable bundles are suspended from anchoring points, then cable support is achieved, but uneven weight distribution creates excessive stress
Solution Approach 1:
By separating the anchoring function (mounting assembly) from the cable support function (cable tray portion), the device achieves even weight distribution. The cable tray portion provides a broad base that distributes cable weight evenly across multiple support points before transferring the load to the mounting assembly.
4Ease of manufacture
If simple cable support structures are used, then ease of installation is achieved, but insufficient stiffness allows bending under cable weight
Solution Approach 1:
The support device is constructed from metal material that provides both ease of manufacture (through forming and punching operations) and sufficient stiffness (through the integrated box-shaped structure with stiffening features). The metal construction allows the device to be formed into a rigid box shape that resists bending while maintaining manufacturing simplicity.

AI summary
A one-piece cable support having a box-shaped mounting assembly. The box-shaped mounting assembly extends over a cable tray portion of the cable support and includes several optional mounting apertures. Once secured to a building structure through the box-shaped assembly, the weight of a suspended bundle of cables is distributed evenly below the box-shaped assembly, thereby permitting the load to be balanced evenly below the assembly and reducing the bending moment and therefore the stress on the wall portion connecting the cable tray and mounting assembly portions of the support. A bracket assembly is provided on the bottom of the cable support to allow easy ganging of multiple cable supports without the need for specialized brackets. Stiffeners are included on the cable support to improve the withstanding of bending forces. A cable retaining arrangement secures cable bundles within the support.
