PV Module Corner Clamp for Below-Purlin Carport Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of efficient and simple systems for assembling solar photovoltaic module arrays onto carport purlins, as installers typically work from below the modules, requiring a method to securely fasten modules from this vantage point while allowing for easy installation and potential mid-module removal.
Innovation Solution
A clamping assembly that secures the corners of four photovoltaic modules to a beam or purlin, featuring a rotating connector with arms that lock into side grooves and a fastener to adjust the gap for secure attachment, allowing for installation and operation from below the array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If installers work from below the modules to assemble carport arrays, then safety is improved (no roof work), but assembly complexity increases (need special clamping systems)
Solution Approach 1:
The clamping assembly is designed to be operated from below the photovoltaic modules, inverting the traditional assembly approach where installers work from above. The rotating connectors and fasteners are positioned to allow installation personnel to secure modules to purlins while standing on the ground, eliminating the need for roof work and improving safety.
2Productivity
If a clamping assembly secures four modules simultaneously, then productivity is improved, but device complexity increases
Solution Approach 1:
The clamping assembly combines multiple functions into a single device: it secures four photovoltaic modules simultaneously to a purlin while providing both rotating connectors for module attachment and fasteners for purlin securing. This merging of functions allows one assembly unit to complete what would otherwise require multiple separate operations, significantly improving productivity.
3Reliability
If rotating connectors lock into side grooves, then reliability is improved (secure locking), but ease of operation decreases (requires rotation and alignment)
Solution Approach 1:
Instead of requiring installers to reach above the modules to secure connectors, the rotating connectors are designed to be operated from below. The rotation and locking action is performed while the installer stands on the ground, making the operation more accessible despite the mechanical complexity of rotation and alignment.
4Adaptability or versatility
If the fastener adjusts the gap size, then adaptability is improved (works with different beam shapes), but device complexity increases
Solution Approach 1:
The fastener mechanism allows adjustment of the gap size between clamping assembly components, enabling the same assembly design to accommodate different purlin and beam shapes and sizes. By making the gap dimension variable rather than fixed, the system gains adaptability to various structural configurations without requiring multiple specialized tools.

AI summary
A clamping system for securing the corners of four photovoltaic modules to a carport purlin, the clamping system having upper and lower body portions with a size adjustable gap to receive the purlin therein, and a pair of rotating connectors at opposite ends of the clamp assembly, each rotating connector having arms extending from opposite sides, the arms being rotated to lock into side grooves in the photovoltaic modules.
