Strut Channel Clip Fitting for Quick Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching multiple strut channel pieces together, such as welding, are time-consuming and costly, and do not allow for easy disassembly or modification during installation.
Innovation Solution
A clip fitting with angled clip arms and a central portion featuring dimples and pockets for tool engagement, allowing for secure side-by-side connection and easy adjustment of strut pieces using a screwdriver, enabling quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to attach multiple strut pieces together, then the connection strength is improved, but the installation time and cost increase significantly
Solution Approach 1:
The connection system is segmented into separate components: a fitting device with clip arms and a strut piece with an external fitting groove. This allows the connection to be made through mechanical engagement rather than welding, enabling quick assembly and disassembly while maintaining connection strength.
Solution Approach 2:
The fitting device acts as an intermediary component between two strut pieces. It features clip arms that extend into the external fitting groove of the strut, providing a strong mechanical connection without requiring welding. The intermediary fitting enables both strength and ease of installation.
2Strength
If welding is used to attach strut pieces, then the connection is strong, but the ability to disassemble and modify during installation is lost
Solution Approach 1:
The connection system transitions from a static welded joint to a dynamic, reversible mechanical connection. The fitting device can be easily attached and detached from the strut pieces, allowing the structure to be modified, adjusted, or reconfigured during installation or future maintenance while maintaining connection strength through the clip arm engagement with the external fitting groove.
3Strength
If conventional welding methods are used, then the attachment is permanent and strong, but the cost and complexity of the installation process increase
Solution Approach 1:
The fitting device is designed to be self-installing through a simple snap-fit or clip mechanism. The clip arms automatically engage with the external fitting groove when the fitting is placed on the strut, eliminating the need for complex welding equipment, skilled welders, or multi-step installation procedures. The connection achieves both strength and installation simplicity through this self-service design.

AI summary
In one aspect, a fitting for connecting first and second pieces of strut to one another, wherein each piece of strut includes an elongate strut body having opposite longitudinal ends, a length extending between the opposite longitudinal ends, and a fitting side defining an external fitting groove extending lengthwise of the body, includes a first clip arm configured to extend into the external fitting groove of the first piece of strut. A second clip arm is configured to extend into the external fitting groove of the second piece of strut. A central portion is connected to and extends between the first and second clip arms. The central portion includes a first dimple configured to receive a tool and a second dimple configured to receive a tool.
