Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the solar device area is increased to collect more energy, then the energy collection area is improved, but the shading problem becomes more severe and reduces the effective power generation area
Solution Approach 1:
The patent introduces a spacing dimension between the light-transmitting panel and photoelectric converting module, transforming the problem from a two-dimensional area optimization to a three-dimensional spatial arrangement. By creating a vertical separation distance, the system allows light to reach the solar device without being blocked by the panel, effectively adding a new dimension to resolve the shading contradiction.
Solution Approach 2:
The spacing between the panel and solar device acts as an intermediary space that mediates the light transmission path. This intermediate region allows light to travel from the display region through the spacing to the power generation region without obstruction, effectively decoupling the shading problem from the area expansion goal.
2Device complexity
If the light-transmitting panel is placed close to the solar device, then the device structure is compact, but thermal interference and shading reduce power generation efficiency
Solution Approach 1:
The patent resolves the conflict between compactness and efficiency by utilizing the vertical spacing dimension. Rather than reducing horizontal area, the system maintains a controlled vertical distance that simultaneously achieves thermal management, shading prevention, and structural integration, effectively using the third dimension to balance opposing requirements.
Solution Approach 2:
The patent optimizes the spacing parameter between the panel and solar device to achieve optimal performance. By carefully controlling this distance parameter, the system balances thermal interference reduction, shading prevention, and structural compactness, demonstrating parameter optimization to resolve the contradiction between closeness and efficiency.
3Adaptability or versatility
If the incident angle of ambient light changes, then the optical path changes, but the effective energy penetration to the solar device is reduced
Solution Approach 1:
The vertical spacing creates an extended optical path in the third dimension, allowing light to reach the solar device from various incident angles without being blocked by the panel. This dimensional approach enables the system to accommodate changing light conditions while maintaining energy transmission efficiency.
