Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sheet solar cells are combined into a module in a fixed state, then structural stability is improved, but adaptability and replaceability deteriorate
Solution Approach 1:
The solar cell module is divided into individual solar cell units that can be separately attached and detached. Each solar cell can be independently connected to the wiring member through connectors, allowing selective replacement and reconfiguration while maintaining overall module stability.
Solution Approach 2:
The module structure transitions from a fixed rigid assembly to a dynamic reconfigurable system. Connectors enable the solar cells to be attached and detached as needed, providing adaptability in configuration while the wiring member maintains structural stability when cells are connected.
2Strength
If solar cells are attached by hooking onto wiring perpendicular to surface direction, then connection strength is improved, but ease of operation and reliability deteriorate due to bending stress
Solution Approach 1:
Instead of attaching solar cells perpendicular to the surface direction (hooking onto wiring), the connectors are designed to attach parallel to the surface direction. This inversion of the attachment direction eliminates bending stress during attachment and detachment operations while maintaining secure connection.
3Ease of repair
If solar cells are made detachable for replacement, then ease of repair is improved, but reliability deteriorates due to potential damage during attachment and detachment
Solution Approach 1:
By inverting the attachment direction to be parallel rather than perpendicular to the surface, the connector design eliminates bending stress that causes damage during attachment and detachment. This allows frequent replacement operations without compromising the reliability and integrity of the solar cells.
