Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional solar cell module structure is used, then the manufacturing process is simple, but moisture penetrates inside the module reducing durability and lifespan
Solution Approach 1:
The support member is divided into multiple parts: an upper support part, a lower support part, and a connection part. Each part has specific functions - the upper support part supports the upper edge, the lower support part supports the lower edge with extended moisture sealing, and the connection part connects them. This segmentation allows targeted moisture prevention at critical areas without requiring complete structural redesign.
Solution Approach 2:
The lower support part is designed to extend farther toward the middle portion of the solar cell module than the upper support part. This preliminary extension creates an advanced moisture barrier position before moisture can penetrate deep into the module. The sealant applied to the extended portion proactively prevents moisture ingress at the most vulnerable point.
2Reliability
If the support member extends farther toward the center to prevent moisture, then moisture resistance improves, but shadow effects increase reducing light incidence
Solution Approach 1:
The support member has non-uniform extension: the lower support part extends farther toward the center than the upper support part. This local differentiation optimizes moisture sealing at the lower edge where penetration is most severe, while minimizing shadow effects on the upper portion where light incidence is more critical. The connection part bridges these different extension lengths smoothly.
Solution Approach 2:
The support member employs asymmetric design where the lower support part has greater extension toward the module center compared to the upper support part. This asymmetry is strategically applied to match the asymmetric moisture penetration risk - typically higher at the lower edge due to gravity-driven water flow and condensation patterns - while maintaining optimal light exposure for the upper solar cells.
3Reliability
If sealants are applied to prevent moisture penetration, then durability improves, but manufacturing complexity increases
Solution Approach 1:
The support member integrates multiple functions into a single component: structural support (upper and lower support parts), moisture sealing (extended lower part with sealant application), and electrical isolation. By combining these functions into one integrated part rather than separate components, the design reduces the number of assembly steps and materials needed while achieving comprehensive moisture protection.
Solution Approach 2:
The connection part serves as an intermediary element that joins the upper and lower support parts. It provides a built-in interface for sealant application, acting as a mediator between the structural support function and the moisture sealing function. This intermediary design simplifies manufacturing by providing a predetermined sealing surface rather than requiring separate sealing operations between multiple components.

AI summary
A solar cell panel is discussed. The solar cell panel includes a solar cell module, a support member attached to an edge of the solar cell module to support the solar cell module by elasticity of the support member, and a frame including a female type coupling unit including an upper coupling unit, a lower coupling unit, and a connection coupling unit connecting the upper coupling unit to the lower coupling unit. The support member includes an upper part, a lower part, and a connection part connecting the upper part to the lower part. An end of the lower part protrudes further than an end of the upper part toward a middle of the solar cell module. The frame supports the solar cell module by coupling the support member to the female type coupling unit.
