Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a solar cell is embedded in a hole or hollow formed on a window, then power generation capability is improved, but window functions such as heat resistance and mechanical resistance are degraded
Solution Approach 1:
The invention divides the solar cell system into a separate module that can be mounted on the window surface without embedding it in the window structure. The solar cell is placed in a frame member that is attached to the window, maintaining window integrity while enabling power generation.
Solution Approach 2:
A frame member acts as an intermediary between the solar cell and the window. This frame member holds the solar cell and connects it to the window through support members, preventing direct embedding while maintaining both power generation and window function.
2Adaptability or versatility
If a solar cell is embedded inside window glass, then integration is improved, but replacement cost increases when lifespans mismatch
Solution Approach 1:
The solar cell is separated from the window glass into an independent module. The frame member containing the solar cell can be detached and replaced independently from the window, allowing selective replacement based on component lifespan without replacing the entire window assembly.
Solution Approach 2:
The mounting system allows for dynamic replacement of the solar cell module. The frame member can be easily attached and detached from the window, enabling flexible maintenance and replacement operations without permanent integration.
3Ease of operation
If a member with embedded solar cell is mounted independently of a window, then ease of mounting is improved, but connection work requires expert knowledge
Solution Approach 1:
The frame member is designed with universal mounting features that can be attached to various window types using standard support members. The terminal structure provides universal electrical connection points that simplify wiring and reduce the need for specialized installation knowledge.
Solution Approach 2:
The mounting system is designed to be self-explanatory and easy to assemble. The support members and frame member incorporate features that guide proper installation, reducing the need for expert knowledge while maintaining secure mounting and proper electrical connections.
