PV Module Framing and Coupling for Support-Free Array Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photovoltaic (PV) module mounting systems require separate structural support members that span between multiple PV modules, leading to increased costs and installation time, and lack efficient cable management solutions.
Innovation Solution
A PV module framing and coupling system that allows for the attachment of PV modules to a roof or mounting surface without separate structural support members, featuring a slidable parallel coupling system for improved structural load distribution, a rotating portion for alignment, and a wire clip for cable management, enabling secure interlocking and grounding of modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate structural support members are used to span between multiple PV modules, then structural support is provided, but costs and installation time increase
Solution Approach 1:
The patent combines the framing function and structural support function into a single integrated frame structure. The frame members directly provide both the enclosure for PV laminate protection and the structural support for mounting, eliminating the need for separate support members and reducing installation complexity and time
Solution Approach 2:
The frame structure is designed to perform multiple functions simultaneously: it encloses and protects the PV laminate edges, provides structural support for mounting to roofs or surfaces, and enables interconnection between multiple modules. This multi-functionality eliminates the need for additional dedicated support components
2Strength
If separate structural support members are used to span between multiple PV modules, then structural support is provided, but material costs increase
Solution Approach 1:
The patent merges the framing structure and structural support elements into a single integrated component system. The same frame members that enclose the PV laminate also serve as the structural support, eliminating the need for additional support members and reducing total material quantity and cost
Solution Approach 2:
The frame is designed as a multi-functional component that simultaneously provides edge protection, structural support, and module interconnection capabilities. This universality reduces the total number of components needed and lowers material costs while maintaining structural integrity
3Ease of operation
If PV modules are interconnected without separate support members, then installation is simplified, but structural load distribution must be improved
Solution Approach 1:
The frame is divided into multiple frame members that can be independently connected to adjacent modules. This segmentation allows for simplified modular installation while the collective arrangement of these segmented members provides distributed structural load support across the entire array
Solution Approach 2:
The frame members are designed with universal connection features that enable both simplified interconnection and structural load bearing. The same connection mechanisms used for easy assembly also provide the structural integrity needed for load distribution

AI summary
A PV module framing and coupling system which enables the attachment of PV modules to a roof or other mounting surface without requiring the use of separate structural support members which attach directly to and span between multiple PV modules in a formed PV array and a cable management system that holds, directs, organizes, and otherwise manages cables, wires, cord, and similar components of and relating to a PV array.
