Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If photovoltaic modules are installed by puncturing metal panel building surfaces, then secure attachment is achieved, but leakage and corrosion issues occur
Solution Approach 1:
The patent introduces mounting clips as intermediary components that attach to the building surface without puncturing it. The clips engage with the metal panels through clamping mechanisms, providing secure attachment while maintaining the integrity of the building surface and preventing leakage and corrosion pathways.
Solution Approach 2:
The mounting system is divided into separate components: mounting clips, module brackets, and attachment mechanisms. This segmentation allows the clips to be positioned at specific locations on the building surface without requiring punctures, while still providing secure attachment for the photovoltaic modules.
2Strength
If expensive metal panel building surfaces are used, then structural integrity and aesthetics are improved, but installation costs increase
Solution Approach 1:
The mounting clips are designed to self-adjust and self-lock onto the metal panel surfaces through elastic deformation and geometric interlocking. This self-service mechanism eliminates the need for complex fastening procedures and expensive specialized installation equipment, reducing labor costs while maintaining secure attachment on expensive metal panel surfaces.
3Strength
If mounting clips are designed for secure engagement, then module retention is improved, but installation complexity increases
Solution Approach 1:
The mounting clips incorporate elastic deformation capabilities that allow them to dynamically adjust during installation. The clips can be easily inserted and then automatically lock into place through spring-loaded or elastomeric mechanisms, providing secure engagement without requiring complex multi-step installation procedures or specialized tools.

AI summary
A module bracket includes first and second mounting clips (202, 204) that are spaced from each other along the pitch of a roofing surface. An inlet (212) to the first mounting clip (202) faces or projects in the general direction that the second mounting clip (204) is spaced from the first mounting clip (202). An inlet (212) to the second mounting clip (204) faces or projects in the general direction that the first mounting clip (202) is spaced from the second mounting clip (204). A second module flange (134) of a first photovoltaic module (120) is slid into the first mounting clip (202) of the module bracket. A first module flange (128) of a second photovoltaic module (120) is slid into the second mounting clip (204) of this same module bracket.
