Solar Panel Grounding Clip for Fast Frame-to-Strut Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional solar panel mounting and grounding methods are time-consuming, complex, and costly to install, especially on windy sites, and often require extraneous fasteners, which can compromise electrical continuity and reliability.
Innovation Solution
A single-piece metallic grounding clip with barbs and flexible wings that snap-fit onto a solar panel frame and a strut, providing both frame grounding and attachment without threaded fasteners, allowing for pre-assembly and reducing labor costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional threaded fasteners and multi-piece brackets are used for mounting solar panel frames, then frame retention is provided, but installation time and complexity increase significantly
Solution Approach 1:
The patent combines multiple functions (grounding, attachment, and electrical continuity) into a single integrated grounding clip component, eliminating the need for separate threaded fasteners, brackets, and grounding lugs. This merging of functions directly reduces installation time and complexity while maintaining frame retention strength.
Solution Approach 2:
The grounding clip serves multiple functions simultaneously: it provides mechanical attachment to the solar panel frame, establishes electrical grounding continuity, and secures the frame to the mounting structure. This multi-functionality eliminates the need for multiple separate components and reduces the number of installation steps.
2Reliability
If conventional grounding lugs with set screws are used, then electrical grounding is provided, but installation complexity and time increase
Solution Approach 1:
The grounding function is merged with the structural attachment function in a single clip component. The grounding clip directly contacts the solar panel frame to establish electrical continuity while simultaneously providing mechanical attachment, eliminating the need for separate grounding lugs and set screws.
Solution Approach 2:
The grounding clip is designed to be self-installing through a simple linear insertion motion that simultaneously achieves both mechanical attachment and electrical grounding. The barbs and flexible wings self-adjust to secure the frame while maintaining continuous electrical contact, requiring no additional fasteners or adjustment steps.
3Strength
If multiple loose parts such as threaded fasteners and nuts are used, then secure attachment is achieved, but assembly cost and labor expense increase
Solution Approach 1:
Multiple separate components (fasteners, nuts, brackets, grounding lugs) are merged into a single integrated grounding clip that provides all necessary functions. This eliminates the need to handle, organize, and install multiple loose parts, directly improving assembly speed while maintaining attachment security through the clip's barb and flexible wing design.
4Strength
If traditional multi-component mounting systems are used, then frame retention is provided, but manufacturing and installation costs increase
Solution Approach 1:
The patent consolidates multiple separate manufactured components into a single grounding clip that can be produced more efficiently. This single-component design reduces manufacturing complexity, material waste, and assembly operations, leading to lower overall costs while maintaining the required frame retention strength.
