Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If structural reinforcements or additional structures are used to support photovoltaic panels on existing roofs, then the panels can be securely installed, but the installation cost increases and the complexity of the system increases
Solution Approach 1:
The patent introduces an intermediary polymeric base that sits between the existing roof tiles and the photovoltaic panels. This base provides a stable mounting surface without requiring structural modifications to the roof, thereby securing the panels while avoiding complex additional structures.
Solution Approach 2:
The polymeric base is designed to replicate the shape and characteristics of the existing roof tiles, creating a complementary fitting that distributes the load across multiple tiles. This copying approach allows secure panel installation by mimicking the roof's existing geometry rather than imposing a complex structural framework.
2Adaptability or versatility
If photovoltaic tiles with built-in panels are used, then the panels can be integrated into the roof, but the existing roof must be removed which increases installation cost
Solution Approach 1:
The system is segmented into separate functional components: the existing roof structure remains intact, the polymeric base is installed independently on the roof surface, and the photovoltaic panels are mounted on the base. This segmentation allows integration of PV panels without removing or replacing the existing roof tiles.
Solution Approach 2:
Instead of integrating panels directly into the roof tiles (as in traditional PV tiles), the invention inverts the approach by placing a polymeric base on top of the existing tiles and mounting the panels on the base. This reversal eliminates the need to remove the existing roof while achieving integration.
3Ease of operation
If photovoltaic panels are installed on the low ridges of tiles, then installation is simplified, but the angle of incidence for solar rays is suboptimal reducing energy generation efficiency
Solution Approach 1:
The polymeric base is designed with adaptive geometry that allows it to conform to the high ridges of the tiles. This dynamic shaping enables the panels to be positioned at the optimal angle for solar capture while maintaining simple installation through the flexible polymeric mounting surface.
Solution Approach 2:
The invention changes the mounting position parameter from the low ridges to the high ridges of the tiles. This parameter change optimizes the angle of incidence for solar rays, improving energy generation efficiency while the polymeric base maintains installation simplicity through its adaptable mounting mechanism.
4Strength
If the support structure uses materials with high heat absorption, then structural strength is maintained, but heat transmission to the photovoltaic panel increases reducing efficiency
Solution Approach 1:
The patent employs composite polymeric materials that incorporate heat-reflective additives and thermal barriers. These composite materials provide the necessary structural strength to support the photovoltaic panels while simultaneously reflecting solar radiation and reducing heat transmission to the panels, thereby maintaining energy generation efficiency.
