Solution Overview
Problem
Existing support systems for photovoltaic (PV) modules are complex and difficult to assemble and adjust, requiring the removal and readjustment of surrounding modules when replacing a single module in an array.
Innovation Solution
A PV module support system featuring a frame with elongate slots and a joining rail with spaced walls, allowing for easy sliding and secure fastening of modules, enabling positional adjustment and replacement without disturbing the entire array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clamps, brackets, fasteners and rails are used to secure PV modules, then the modules can be properly secured to withstand environmental effects, but the system becomes complex and difficult to assemble and adjust
Solution Approach 1:
The patent combines multiple support functions into a single integrated rail structure that spans across multiple PV modules. The rail integrates positioning, support, and securing functions that were previously distributed across separate clamps, brackets, and fasteners. This merging reduces the number of components and simplifies the overall support system while maintaining reliability.
Solution Approach 2:
The rail structure serves multiple functions simultaneously: it provides structural support, enables positional adjustment through slots, secures modules through fasteners, and allows for easy replacement. This multi-functionality eliminates the need for separate specialized components for each function, reducing system complexity while maintaining security.
2Reliability
If traditional support systems are used, then PV modules can be secured to structures, but replacing a single module requires removal and readjustment of surrounding modules
Solution Approach 1:
The rail structure is divided into discrete sections with standardized slots and fastening points that allow individual modules to be accessed and replaced independently. Each module can be secured and released from the rail without affecting the structural integrity or positioning of adjacent modules, enabling easy repair and maintenance.
Solution Approach 2:
The system incorporates movable fasteners and adjustable slots that allow for dynamic securing and releasing of individual modules. The fasteners can be quickly engaged and disengaged, and the slots allow for positional adjustment, making the system adaptable for easy module replacement while maintaining secure installation during operation.
3Manufacturing precision
If multiple clamps and fasteners are used to secure PV modules, then the modules can be properly positioned, but alignment and assembly become difficult
Solution Approach 1:
The rail structure incorporates pre-positioned slots and alignment features that guide module placement during assembly. The slots are precisely positioned to ensure correct alignment, and the rail itself is pre-assembled with fastening points, eliminating the need for complex field alignment of multiple separate components and simplifying the assembly process.
