Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a two-stage structure with three panels is used, then the solar panel unit can be assembled with a simpler structure, but the wind load received by the panels cannot be sufficiently reduced
Solution Approach 1:
The solar panel unit is divided into four separate panels arranged in a specific spatial configuration. Each panel is positioned at a predetermined distance from the others, creating gaps that allow wind to pass through. This segmentation of the continuous surface into discrete elements reduces the overall wind load while maintaining structural simplicity.
Solution Approach 2:
The panels are arranged not only in the horizontal plane but also in the vertical dimension, creating a three-dimensional configuration. The second and third panels are disposed at positions behind the first panel in a direction orthogonal to the front surface, adding depth to the structure. This multi-dimensional arrangement allows wind to flow through the gaps between panels, effectively reducing wind load while maintaining a relatively simple assembly.
2Object-affected harmful factors
If panels are disposed with gaps between them, then the wind load can be reduced, but the photovoltaic element area is decreased
Solution Approach 1:
Instead of reducing the horizontal area of individual panels, the invention utilizes the vertical and depth dimensions to create gaps between panels. The second and third panels are positioned behind the first panel at predetermined distances, creating three-dimensional spacing that allows wind flow without sacrificing the front surface area of the panels for photovoltaic elements.
Solution Approach 2:
The fourth panel is disposed at a position symmetrical with the first panel with respect to a plane on which the second and third panels are present, but the fourth panel is not provided with photovoltaic elements. This asymmetric functional arrangement allows the fourth panel to serve as a windbreak or flow director without requiring active photovoltaic conversion, optimizing both wind load reduction and energy generation areas.
3Object-affected harmful factors
If a fourth panel without photovoltaic elements is added, then the wind load distribution is improved, but the device complexity increases
Solution Approach 1:
The fourth panel is extracted from the photovoltaic element configuration, meaning it does not contain photovoltaic elements like the first three panels. This extracted panel serves a specialized function in wind load management and airflow optimization, allowing the photovoltaic elements to be concentrated on the panels where they are most effective while the fourth panel handles aerodynamic functions.
Solution Approach 2:
The fourth panel, although without photovoltaic elements, contributes to the overall functionality of the solar panel unit by improving wind load distribution and potentially directing airflow to enhance the performance of the photovoltaic panels. This multi-functional element adds value to the system beyond simple power generation, optimizing both structural and aerodynamic performance.
