Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive is used to attach thin-film solar battery module to metal roof panel, then installation is simplified, but module detachment occurs due to thermal expansion coefficient difference
Solution Approach 1:
The patent replaces the chemical bonding method (adhesive) with a mechanical fastening system consisting of coupling protrusions that engage with corresponding recesses in the roof panel. This mechanical connection provides reliable attachment that is not affected by thermal expansion differences between materials, while maintaining installation simplicity through the integrated coupling structure.
Solution Approach 2:
The panel structure is divided into distinct functional components: the roof panel body, coupling protrusions for mechanical attachment, and concave sections for thermal management. This segmentation allows each component to perform its specific function optimally - mechanical fastening for attachment stability and concave sections for heat dissipation - while working together as an integrated system.
2Reliability
If solar battery module is tightly fixed to roof panel, then attachment stability is improved, but heat dissipation efficiency decreases
Solution Approach 1:
The patent applies different structural characteristics to different regions of the panel: the coupling protrusions provide rigid mechanical fastening for stable attachment, while the concave sections create localized air spaces for heat dissipation. This local differentiation allows the panel to simultaneously achieve both attachment stability and thermal management efficiency by optimizing each region for its specific function.
Solution Approach 2:
The concave sections act as intermediary thermal management features between the solar battery module and the roof panel. These recessed areas create air gaps that facilitate heat dissipation from the module without compromising the mechanical attachment provided by the coupling protrusions, thus mediating between the conflicting requirements of stable fixation and effective cooling.
3Ease of manufacture
If conventional installation method is used, then material cost is reduced, but power generation efficiency decreases due to poor heat dissipation
Solution Approach 1:
The panel structure integrates multiple functions into a single system: mechanical attachment through coupling protrusions and thermal management through concave sections. This multi-functional design achieves both reliable module fixation and effective heat dissipation without requiring separate components, thereby maintaining cost-effectiveness while improving power generation efficiency through better thermal management.
