Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation, storage, and transportation of photovoltaic (PV) modules are cumbersome due to the need for numerous parts and labor-intensive processes, and there is a risk of panel damage during these operations.
Innovation Solution
The use of corner connection members with through-holes in PV module frames allows for simplified assembly, stacking, and array configurations through the use of inserts and connecting rods, facilitating mechanical and electrical connections while enhancing structural integrity and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional corner connectors are used to attach frame members, then the frame structure is formed, but the installation process requires many additional parts and substantial labor
Solution Approach 1:
The corner member integrates multiple functions into a single component: it serves as both the corner connector and includes an integrated through-hole for direct attachment to the support structure. This eliminates the need for separate connectors and additional fastening parts, reducing the total number of components and simplifying the installation process.
Solution Approach 2:
The corner member is designed with multi-functionality: it connects frame members at corners, provides structural support, and includes a through-hole for direct mounting to support structures. This universal design reduces the need for specialized parts and simplifies the overall assembly process.
2Ease of operation
If traditional installation methods are used, then PV modules can be installed, but additional wiring is required for electrical connections and grounding
Solution Approach 1:
The corner member with integrated through-hole serves multiple purposes: structural connection of frame members and direct mounting to support structures. This multi-functional design reduces the need for separate wiring and grounding components, as the same structural element can accommodate both mechanical and electrical connection needs.
3Reliability
If framed PV modules are assembled with traditional methods, then the modules are functional, but they are difficult to safely store and transport
Solution Approach 1:
The corner member combines the frame connection function with an integrated attachment feature (through-hole) that enables direct securing to support structures. This integration provides more secure mounting and protection during storage and transport, while the standardized design facilitates easier handling and assembly.

AI summary
Corner connection members for a photovoltaic module frame include thru-passages for receiving insert components that perform and facilitate a variety of functions, such as attaching the photovoltaic module to a roof, providing a ground connection for the solar cells, to facilitate the mechanical and electrical connection of photovoltaic modules which are arranged side-by-side, to facilitate securing photovoltaic modules in a stack, and providing mechanical and electrical connections to adjacent photovoltaic modules in an array. Insert components may also include electronic devices, such as microinverters and energy storage devices, which are connected to the photovoltaic modules when the insert component is installed in the corner member.
