Solar Module Clamping Profile for Uniform Force Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices for solar modules do not effectively redirect tensile and pressure forces into carrier structures uniformly and are costly, complicating assembly and ensuring proper spacing.
Innovation Solution
A clamping device constructed in one piece with non-resilient, bending-resistant side wall portions that securely redirect forces into carrier structures, allowing for adjustable spacing and simplified assembly, using materials like metal with extruded profiles for cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resilient members are used to receive solar modules, then the clamping device can adapt to different carrier structures, but the force redirection is not uniform and the structure becomes more complex
Solution Approach 1:
The patent combines the resilient receiving member and the rigid force-redistributing profile into a single integrated receiving region. This merging eliminates the interface between separate components, ensuring uniform force redirection while maintaining adaptability to different carrier structures through the resilient nature of the integrated receiving region.
2Ease of manufacture
If multiple separate components are used to form the clamping device, then manufacturing flexibility is improved, but production costs increase and assembly becomes more complex
Solution Approach 1:
The patent merges multiple functional components (receiving member, clamping wings, support elements) into a single monolithic receiving region formed from one extruded profile. This reduces the number of parts, simplifies assembly, and lowers production costs while maintaining manufacturing flexibility through profile design variations.
3Strength
If rigid profiles are used to ensure bending resistance, then structural strength is improved, but the ability to accommodate spacing variations is reduced
Solution Approach 1:
The patent applies different structural qualities to different parts of the receiving region: the outer shell provides rigid bending resistance through its profile geometry, while the inner receiving surface maintains resilience to accommodate spacing variations and absorb thermal expansion. This local differentiation of mechanical properties resolves the contradiction between rigidity and adaptability.
