High-Voltage Cable Cleat With Integral Roller for Faster 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 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, reducing the need for external rollers and machinery, and accommodating various cable configurations.
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 possible, 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 unit. This eliminates the need for external rollers and reduces the complexity of installation equipment required.
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 during installation.
2Ease of operation
If traditional two-piece cleats are used, then cable support is provided, but cable movement during installation is not facilitated
Solution Approach 1:
The roller function is merged with the cleat structure, allowing the same component to both support the cable and facilitate its movement during installation, thereby improving productivity without compromising cable support.
3Ease of operation
If top cleats are removed and replaced during cable installation, then cable can be positioned, but installation time increases
Solution Approach 1:
The upper clamps are designed to be movable during installation, allowing the cleat to dynamically adapt to the cable installation process. After installation, the clamps secure the cable firmly, providing both ease of operation during positioning and time efficiency.
4Productivity
If heavy machinery is used to pull cables, then cable installation is achieved, but friction and weight make the process arduous
Solution Approach 1:
The roller integration converts the harmful friction force into a beneficial rolling motion. By allowing the cable to roll through the cleat rather than slide, the friction is significantly reduced, making the installation process less arduous and more productive.
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 easier and faster cable installation by integrating a roller and clamps, reducing installation time and cost, and enabling use in submerged environments.
Implementation Method 1
Massive weight and therefore friction between the cleats and cable make the latter portion of the installation arduous
Implementation Method 2
Lower clamps are rotatably mounted on the roller axle mounted to the roller mount and extending beyond the roller

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.
