Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-sided light-receiving method is used, then the device structure is simple, but the adaptability to different directions and installation methods is limited
Solution Approach 1:
The device is segmented into front-side and back-side light-receiving surfaces, each with independent light-concentrating grooves. This segmentation allows the device to receive light from multiple directions independently, significantly improving adaptability to different installation orientations and directions without requiring complex tracking mechanisms.
Solution Approach 2:
The invention transitions from single-sided (one-dimensional light reception) to double-sided (two-dimensional light reception) by adding light-receiving capability in the opposite direction. This dimensional change enables the device to capture sunlight regardless of its orientation, greatly enhancing installation flexibility and directional adaptability.
2Duration of action of moving object
If a single-sided light-receiving method is used, then the device structure is simple, but the power generation time is limited
Solution Approach 1:
The photovoltaic panel is divided into front and back sides, each equipped with independent light-concentrating grooves. This segmentation allows both sides to generate power simultaneously under different lighting conditions, effectively doubling the potential power generation time without requiring complex sun-tracking systems.
Solution Approach 2:
By enabling light reception from both front and back sides, the device maintains continuous power generation capability throughout the day. The front side captures morning and afternoon sunlight, while the back side captures afternoon and evening sunlight, ensuring uninterrupted useful action and maximizing energy harvest.
3Area of stationary object
If the opening lateral dimension is larger than the bottom dimension, then the light collection area is increased, but the light concentration ratio may be reduced
Solution Approach 1:
The light-concentrating grooves utilize curved or angled reflecting surfaces that guide light from the wider opening toward the narrower bottom where the photovoltaic panel is located. This curved geometry allows the grooves to capture light over a large opening area while effectively concentrating it onto the smaller panel surface, resolving the trade-off between collection area and concentration ratio.
Solution Approach 2:
The grooves extend in the depth dimension, creating a three-dimensional light-guiding structure. This vertical dimension allows light to be collected over a large horizontal opening area and then concentrated through the depth of the grooves onto the photovoltaic panel, effectively decoupling the collection area from the concentration ratio.

AI summary
A double-sided light-concentrating solar apparatus and system. The apparatus comprises a front-side concentrating groove (110), a back-side concentrating groove (110'), and a photovoltaic panel (120) provided at the bottom of each concentrating groove. Each concentrating groove comprises two groove walls (111, 112; 111', 112') extending along the bottom; opposite surfaces of the two groove walls are reflecting surfaces; the open side of each of the two groove walls forms an opening of the concentrating groove; the opening direction of the front-side concentrating groove (110) is opposite to the opening direction of the back-side concentrating groove (110'). According to the double-sided concentrating solar device, sunlight (LL) can be concentrated and received from two different directions, thereby enhancing direction adaptability and expanding device mounting methods.
