Modular assembly system for mounting modules on a lightweight hall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for energy modules are not suitable for lightweight halls with metal or wooden frameworks and membrane roofs, as they require penetrating the membrane, which is undesirable.
Innovation Solution
A module assembly system that uses fastening elements and holding means attached to the outside of the membrane to connect module carriers, such as photovoltaic or thermal solar modules, without penetrating the membrane, utilizing various fixation methods like pockets, tabs, cords, and fixation points, and integrating fall protection and cable routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If commercially available mounting systems are used for membrane roofs, then modules can be mounted, but the membrane must be penetrated with fixing elements which causes damage and reduces reliability
Solution Approach 1:
The patent introduces intermediate holding means (clamps, clips, or adhesive-mounted fixtures) that attach to the membrane without penetration, serving as mediators between the mounting system and the membrane. These holding means provide attachment points for module carriers while preserving membrane integrity.
Solution Approach 2:
The mounting system is divided into separate functional components: holding means that attach to the membrane, module carriers that hold the modules, and connection elements that join them. This segmentation allows each component to be optimized for its specific function without compromising the membrane.
2Reliability
If traditional penetrating fixing elements are used, then secure module attachment is achieved, but assembly complexity and on-site effort increase
Solution Approach 1:
The holding means are pre-assembled and pre-positioned on the membrane before module installation. This preliminary action simplifies the final assembly process, as module carriers can be directly attached to the pre-positioned holding means without complex on-site fabrication or membrane penetration work.
Solution Approach 2:
The holding means are designed to be self-attaching to the membrane using methods such as clamping, clipping, or adhesive bonding without requiring penetration or complex fastening procedures. This self-service capability reduces assembly complexity while maintaining secure attachment.
3Object-affected harmful factors
If membrane penetration is avoided, then membrane integrity is preserved, but mounting system reliability may be compromised
Solution Approach 1:
The holding means are designed to work with the flexible membrane surface, using clamping or adhesive mechanisms that conform to the membrane's thin film structure. This allows secure attachment without penetration, maintaining membrane integrity while ensuring mounting reliability through distributed attachment forces.
Solution Approach 2:
The holding means distribute attachment forces over larger areas and use multiple attachment points, changing the stress parameters from concentrated penetration forces to distributed clamping or adhesive forces. This parameter change maintains mounting reliability while preserving membrane integrity.
