Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting structures with rails and frames are used to integrate photovoltaic panels into roof structures, then the photovoltaic panels can be securely installed, but skilled labor is required and substantial labor and maintenance expenses are incurred
Solution Approach 1:
The patent merges the mounting structure with the roofing sheet by integrating the bracket directly into the roof structure. The bracket is formed as part of the roofing sheet assembly, eliminating the need for separate rails and frames. This integration allows standard labor to perform installation without requiring specialized skilled workers, while maintaining secure panel attachment.
Solution Approach 2:
The roofing sheet structure serves multiple functions: it provides weather protection, structural support, and integrated photovoltaic mounting capability. The bracket is designed to work with standard roofing sheets, making the system universally applicable without requiring specialized installation expertise for each component.
2Ease of manufacture
If brackets and frames are installed on rooftops to support photovoltaic panels, then the panels can be mounted, but significant manpower, time, and cost are required for installation and upkeep
Solution Approach 1:
The bracket is pre-formed as an integrated part of the roofing sheet during manufacturing, rather than being installed separately on the rooftop. This preliminary action transfers the bracket fabrication from the installation phase to the manufacturing phase, reducing on-site installation time and eliminating the need for separate bracket installation steps.
Solution Approach 2:
The patent combines the bracket fabrication process with the roofing sheet manufacturing process. By integrating these operations, the system eliminates separate bracket installation steps on the rooftop, significantly reducing installation time and maintenance requirements while maintaining panel mounting capability.
3Adaptability or versatility
If solar photovoltaic panels are installed on rooftops using brackets and frames, then power generation can be incorporated into buildings, but substantial labor and maintenance expenses are incurred
Solution Approach 1:
The patent merges the photovoltaic mounting system with the building envelope by integrating the bracket into the roofing sheet. This integration maintains building adaptability while eliminating the need for separate maintenance of mounting structures, as the bracket becomes part of the permanent roof assembly requiring no independent upkeep.

AI summary
A photovoltaic system includes a sheet, a bracket, and a photovoltaic panel. The sheet has a base board and two side walls. The two side walls are opposite to each other and connected to the base board. The base board and the two side walls form an accommodating space. The bracket is in the accommodating space. The bracket includes a main portion, a first side portion, and a second side portion. The first side portion extends from a first side of the main portion along one of the two side walls and is coupled to the one of the two side walls. The second side portion extends from a second side of the main portion. The first side is adjacent to the second side. The photovoltaic panel is in the accommodating space and over the main portion of the bracket.
