Ladder Rack Cable Cleat Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems for 3-phase power cables in industrial settings face challenges such as cable mixing during installation, interference with cable pulling due to pre-installed cleats, and the need for various attachment methods for different ladder rungs, which complicates the securement and support of heavy cables, especially during short-circuit events.
Innovation Solution
A ladder rack with integrated V-shaped receptacles and a clamping frame that allows for direct cable installation in a trefoil arrangement, eliminating the need for separate cable cleats by securing cables through pivotally attached clamping frames with adjustable fasteners, accommodating various cable diameters and facilitating efficient cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cable cleats are installed on ladder rungs, then cables can be secured in place, but the cable cleats interfere with cable pulling during installation
Solution Approach 1:
The cable management assembly incorporates pre-formed V-shaped receptacles into the ladder rack structure before cable installation. These receptacles are positioned and configured in advance to guide and receive cables as they are pulled through the ladder rack, eliminating the need for separate cable cleats that would interfere with the pulling process.
Solution Approach 2:
The invention combines the cable support function previously performed by separate cable cleats directly into the ladder rack structure. The V-shaped receptacles are integrated as part of the ladder rack assembly, merging the rack support function with the cable securing function into a single unified structure.
2Adaptability or versatility
If multiple attachment methods are used for different ladder rungs, then various ladder configurations can be accommodated, but the device complexity increases
Solution Approach 1:
The cable management assembly is designed with universal attachment capability that can accommodate different ladder rung configurations. The V-shaped receptacles are structured to work with various ladder rack designs through a single standardized attachment method, eliminating the need for multiple specialized attachment mechanisms for different rung types.
Solution Approach 2:
The cable management assembly is divided into modular V-shaped receptacle units that can be independently attached to different ladder rungs. Each receptacle is a separate component that can be universally mounted on various rung configurations, providing adaptability through modular segmentation rather than complex integrated attachment systems.
3Ease of manufacture
If cable cleats are pre-installed on the ladder rack, then cable management is ready in advance, but the cleats must be moved out of the way during cable installation
Solution Approach 1:
The V-shaped receptacles are pre-formed and integrated into the ladder rack structure during manufacturing, ready to receive cables immediately upon installation. The receptacles are positioned and configured in advance with the correct orientation and spacing to guide cables as they are pulled through, eliminating the need for post-installation adjustment or relocation.
4Reliability
If separate cable cleats are used to secure trefoil cable arrangements, then cables can be held together, but the number of components and installation steps increases
Solution Approach 1:
The invention merges the function of multiple separate cable cleats needed to secure a trefoil cable arrangement into a single integrated V-shaped receptacle. Each receptacle is designed to simultaneously receive and hold multiple cables in the correct trefoil configuration, reducing the total number of components from multiple cleats to a single unified structure.
Solution Approach 2:
The V-shaped receptacle is designed as a multi-functional component that simultaneously performs multiple functions: supporting individual cables, maintaining the trefoil arrangement, and providing structural attachment to the ladder rack. This universal design replaces what would otherwise require multiple specialized components.
