Cable Tray Bracket Assembly for Modular Routing Without Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Overhead cable routing systems require cutting of sidewalls to create tee, cross, or right-angle pathways, making installation time-consuming, costly, and creating sharp edges.
Innovation Solution
A cable routing system formed from a tray with transverse and longitudinal wires, featuring removable sidewalls, corner radius devices, and joining brackets to facilitate easier installation and cable management without cutting, along with drop-down devices and wall mount brackets for enhanced flexibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If integral sidewalls are used in cable basket or cable duct, then structural strength is improved, but installation time and cost increase due to required cutting operations
Solution Approach 1:
The cable tray system is divided into modular sections with standardized configurations. Pre-formed sections include integrated pathways for tees, crosses, and right angles, eliminating the need for on-site cutting and assembly of custom shapes.
Solution Approach 2:
Cable trays are pre-assembled with required pathways and configurations during manufacturing before delivery to the installation site. This preliminary formation of complex geometries eliminates time-consuming field cutting operations.
2Adaptability or versatility
If cutting operations are performed on sidewalls to create pathways, then cable routing flexibility is improved, but creation of sharp edges and safety hazards occurs
Solution Approach 1:
The cable tray system uses modular pre-formed sections with integrated pathways for tees, crosses, and right angles. These standardized segments provide cable routing flexibility without requiring cutting operations that create sharp edges.
Solution Approach 2:
The system employs disposable or replaceable pathway inserts and accessories that can be installed to create routing configurations. These components are designed to be installed without cutting the main tray structure, avoiding permanent modifications and sharp edges.
3Adaptability or versatility
If custom pathways are created through cutting, then specific routing requirements are met, but installation cost increases
Solution Approach 1:
The cable tray system is divided into modular sections with standardized configurations. Pre-formed sections include integrated pathways for tees, crosses, and right angles, eliminating the need for on-site cutting and assembly of custom shapes.
Solution Approach 2:
Standardized cable tray sections are designed to accommodate multiple routing configurations through integrated features and accessories. A single universal section type can serve various routing needs, reducing the variety of custom components required.

AI summary
The present invention is directed to a cable routing system with a bracket that joins adjacent cable trays. The bracket includes a main body with upper members, a bottom member and sides. The upper members have a space therebetween to retain transverse wires of adjacent cable trays. The sides include generally C-shaped arms extending from the sides of the main body and along the back of the main body. When the bracket is secured to the adjacent cable trays a longitudinal wire of each cable tray is positioned between the upper members and the sides of the main body.
