Longitudinal profile and module clamp for a mounting system for solar modules, and a mounting system of such a type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for solar modules are either expensive to produce or lack the necessary strength to withstand high loads, and they require additional fastening elements for secure attachment.
Innovation Solution
A longitudinal profile with a stop area for attachment to a transverse profile and a head area for securing solar module frames, featuring gripping projections and a fastening system that allows for secure fastening without additional screws, along with a connecting profile for screw-free connections between longitudinal profiles, and a module clamp with a clamp-shaped body and screw for tensile force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting systems use additional fastening elements for secure attachment, then the strength and reliability of the connection is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent combines the longitudinal profile and transverse profile into a single integrated component with an L-shaped cross-section. The flange portion attaches to the transverse profile while the web portion provides the mounting surface for solar modules, eliminating the need for separate fastening elements and reducing overall system complexity while maintaining connection strength
Solution Approach 2:
The integrated profile serves multiple functions simultaneously: it provides structural support, creates rigid connections between longitudinal and transverse elements, and offers mounting surfaces for solar modules. This multi-functionality reduces the number of separate components needed in the mounting system
2Ease of manufacture
If traditional mounting systems use multiple separate components for attachment, then the ease of manufacture is improved, but the overall strength and stability of the structure deteriorates
Solution Approach 1:
By merging the longitudinal and transverse profiles into a single L-shaped component, the patent creates inherent rigidity through the integrated geometry. The perpendicular flange and web portions form a rigid structure that resists deformation better than separate components could achieve, while still being manufacturable as a single piece
3Reliability
If additional fastening elements are used to secure solar modules, then the reliability of the mounting system is improved, but the production cost increases
Solution Approach 1:
The patent extracts the fastening function from separate fastening elements and integrates it directly into the profile structure itself. The integrated design provides built-in attachment capability through its geometry, eliminating the need for additional fasteners and reducing production costs while maintaining secure attachment of solar modules
