Pivoting Cable Cleat Assembly for Short Circuit Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable cleat designs fail to effectively secure cables during short circuit events, allowing them to separate due to high electromagnetic forces, which can lead to damage and safety hazards.
Innovation Solution
A cable cleat assembly with a base and pivotally mounted side bodies, featuring pegs and slots that allow the side bodies to rotate from an open to a closed position around the cables, securing them to a ladder rack using a fastener, and incorporating a design that eliminates the need for separate hinges and reduces production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable cleat designs are used, then the structure is simple and easy to manufacture, but the cables cannot be effectively secured during short circuit events and may separate due to high electromagnetic forces
Solution Approach 1:
The cable cleat assembly is divided into multiple functional segments: a base body for mounting, side bodies for cable containment, and a compression member for securing. This segmentation allows each component to perform its specific function effectively while maintaining overall structural integrity during short circuit events.
Solution Approach 2:
The side bodies are designed to be movable relative to the base body, allowing the assembly to dynamically adapt to cable installation requirements. The side bodies can be positioned to accommodate cables and then secured in place, providing both ease of installation and reliable securing during operation.
2Strength
If rigid cable retention structures are used, then cables are secured during short circuit events, but the device requires more complex components such as separate hinges and mounting mechanisms
Solution Approach 1:
The mounting functions are merged into the base body itself, which includes integrated mounting surfaces and attachment features. This eliminates the need for separate mounting brackets or hinges, reducing the number of parts while maintaining the strength required to resist electromagnetic forces during short circuits.
Solution Approach 2:
The base body serves multiple functions: it provides structural support, acts as the mounting platform for the ladder rack, and houses the mechanism for securing the side bodies. This multi-functionality reduces the overall component count and simplifies manufacturing while maintaining the required strength.
3Ease of manufacture
If traditional mounting methods are used, then the cleat structure is simple, but separate mounting components increase production costs and galvanic corrosion risks
Solution Approach 1:
The mounting features are combined directly into the base body structure, eliminating the need for separate mounting brackets or attachment components. This reduces the number of parts that need to be manufactured and assembled, lowering production costs while reducing the risk of galvanic corrosion between dissimilar metals.
Solution Approach 2:
The base body is designed as a multi-functional component that simultaneously provides structural support, mounting attachment, and housing for the securing mechanism. This universality reduces the total component count, simplifying manufacturing and assembly while maintaining reliable cable securing effectiveness.

AI summary
A cable cleat assembly secures a bundle of cables to a ladder rack. The cable cleat assembly includes a base and two side bodies. Each side body is pivotally mounted to one of the ends of the base. Each side body has a first end, a middle section, and a second end. The first end of each side body includes a mounting member. The mounting member has a peg extending from each side of the mounting member and a circumferential rib. The pegs are mounted in the base with the circumferential rib positioned between alignment ribs extending from the base to enable the side bodies to pivot from an open position to a closed position.
