Interlocking Cable Cleat Structure for Short-Circuit Cable Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable cleat technologies fail to effectively manage and secure 3-phase power cables during short-circuit events, where electromagnetic forces can cause cables to repel and lead to damage.
Innovation Solution
The development of interlocking cable cleats with identical halves that include strengthening ribs, studded gripping surfaces, and semi-circular keys for secure clamping, along with optional drain holes to prevent water accumulation, allowing for secure cable management across various diameters and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable cleats are used to secure cables, then cables can be held in place during normal operation, but they fail to prevent cable displacement during short-circuit events with high electromagnetic forces
Solution Approach 1:
The cable cleat is divided into two separate halves that can be assembled around the cable. This segmentation allows the cleat to apply clamping force more effectively while maintaining cable security during short-circuit events, as the two halves work together to secure the cable firmly in place.
Solution Approach 2:
One half of the cable cleat includes a strengthening rib that extends along the outer surface, creating an asymmetric structure. This asymmetric design with the strengthening rib increases the cleat's resistance to electromagnetic forces during short-circuit events while maintaining effective cable clamping.
2Strength
If cable cleats are designed with strengthening ribs and interlocking mechanisms, then resistance to electromagnetic forces improves, but device complexity increases
Solution Approach 1:
The cable cleat is divided into two separate halves that can be assembled around the cable. This segmentation allows the cleat to apply clamping force more effectively while maintaining cable security during short-circuit events, as the two halves work together to secure the cable firmly in place.
Solution Approach 2:
One half of the cable cleat includes a strengthening rib that extends along the outer surface, creating an asymmetric structure. This asymmetric design with the strengthening rib increases the cleat's resistance to electromagnetic forces during short-circuit events while maintaining effective cable clamping.
3Adaptability or versatility
If cable cleats are designed for secure clamping of various cable diameters, then adaptability improves, but manufacturing precision requirements increase
Solution Approach 1:
The cable cleat is divided into two separate halves that can be assembled around the cable. This segmentation allows the cleat to apply clamping force more effectively while maintaining cable security during short-circuit events, as the two halves work together to secure the cable firmly in place.
Solution Approach 2:
The cable cleat design with two halves and interlocking mechanisms provides universal applicability across different cable diameters. The cleat can securely clamp various cable sizes while maintaining consistent performance, making it a multi-functional solution for different cable management needs.

AI summary
An interlocking cable cleat secures cables to a ladder rack. The interlocking cable cleat is formed from a first cable cleat half and a second cable cleat half. Each cable cleat half includes an outer surface, an inner surface, and at least one mounting hole extending from the outer surface to the inner surface. Semi-circular keys extend from the inner surface of each cable cleat half around the mounting holes in the cable cleat halves defining slots in the remainder of each mounting hole. Each slot receives one of the semi-circular keys from an opposing inverted cable cleat half to interlock the first cable cleat half to the second cable cleat half.
