Integral-Roller Cable Cleat for Low-Friction HV Cable Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high voltage cable cleats require additional equipment like rollers and machinery for cable installation, which complicates and prolongs the installation process due to friction and weight, and do not facilitate cable movement during installation.
Innovation Solution
A high voltage cable cleat with an integral roller and rotatable clamps that supports cable installation by allowing the roller to freely rotate, accommodating various cable configurations and sag, and is easy to install on surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external rollers and heavy machinery are used to pull cables through cleats, then cable installation is enabled, but device complexity and installation time increase
Solution Approach 1:
The roller is integrated directly into the cable cleat structure, merging two previously separate functions (cable support and cable pulling assistance) into a single unified component. This eliminates the need for external rollers and reduces the complexity of installation equipment while maintaining cable installation capability
Solution Approach 2:
The cable cleat is designed to perform multiple functions: it provides structural support for the cable and simultaneously acts as a roller to facilitate cable pulling through the tunnel. This multi-functionality reduces the number of separate components needed and simplifies the overall installation system
2Strength
If traditional two-piece cleats are used, then cable support is provided, but cable movement is hindered by friction and additional equipment is required
Solution Approach 1:
The roller function is merged into the cleat structure itself, allowing the same component that provides structural support to also facilitate cable movement by reducing friction during the pulling operation
3Ease of operation
If top cleats are removed and replaced during installation, then cable positioning is achieved, but installation time increases
Solution Approach 1:
The roller is pre-integrated into the cleat structure during manufacturing, so that when the cleat is installed, the roller is already in place and functional. This eliminates the need for separate roller installation and top cleat replacement steps, reducing overall installation time while maintaining cable positioning capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient cable installation by reducing the need for external rollers and machinery, minimizing friction, and accommodating cable sag, thus simplifying the installation process.
Implementation Method 1
Massive weight and therefore friction between the cleats and cable make the latter portion of the installation arduous
Implementation Method 2
accommodating cable sag

AI summary
A high voltage cable cleat supports cables on a surface. The high voltage cable cleat includes a roller with a main body, a first end, and a second end. A roller axle is positioned within the roller. The roller axle extends beyond the first end and the second end of the roller. A roller mount receives the roller axle and supports the roller thereon. Lower clamps are rotatably mounted onto the roller axle. Upper clamps are secured to the lower clamps over the cables positioned thereon to form the high voltage cable cleat.
