Cable Tray Coupler Clip Preventing Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for coupling components of support systems for cabling or piping, such as ladder-type and cable tray systems, are inefficient and lack effective solutions for secure and stable assembly, particularly in facilitating the connection of short longitudinal sections.
Innovation Solution
A method and device utilizing a coupler and clip made of galvanized or stainless steel, where the coupler is slid into the side rail with overlapping holes, and a clip is used to secure the assembly with a bolt and spring washer, preventing rotation and leverage between the coupler and side rail, enhancing stability and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional coupling methods using bolts and nuts through multiple holes are used, then connection strength is achieved, but assembly complexity and time increase
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated clip component. The clip incorporates both the fastening element and the rotation prevention mechanism (via the flat portion engaging with the recess) into one piece, eliminating the need for separate bolts, nuts, and alignment features while maintaining connection strength.
Solution Approach 2:
The invention extracts and eliminates unnecessary components from the conventional coupling system. By removing redundant fastening elements and simplifying the coupling mechanism to use only the essential components (coupler and clip), the assembly process becomes less complex while preserving the required connection strength.
2Manufacturing precision
If multiple holes and alignment features are provided for coupling, then assembly precision is improved, but manufacturing complexity increases
Solution Approach 1:
The clip features an asymmetric design with a flat portion on one side that engages with a corresponding recess in the coupler. This asymmetric geometry provides inherent alignment and rotation prevention without requiring multiple symmetric holes or complex alignment features, thereby maintaining assembly precision while reducing manufacturing complexity.
3Reliability
If heavy-duty coupling components are used, then connection reliability is improved, but weight of the support system increases
Solution Approach 1:
The invention changes the material parameters and geometric parameters of the coupling components. The clip is designed with optimized dimensions and material properties that provide sufficient connection reliability for the intended load conditions while minimizing weight. The flat portion's engagement with the recess provides rotation prevention with minimal additional material.

AI summary
A technique comprising: assembling two components of a cable support system to form an assembly, and using a fastener to fasten together at a first location of said assembly said two components and a proximal portion of a third element also having a distal portion that at a second location of said assembly fits through a hole defined by the coincidence of holes or portions thereof defined in said two components, and thereby serves to at least restrict rotation of the two components relative to each other about said fastener at said first location.
