Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multilayer glass window solutions for solar power generation in windows expose the collection wires, making them visible indoors and compromising the aesthetic and safety of the indoor space.
Innovation Solution
A solar cell module is integrated into the window with a translucent substrate configuration and an extraction wire that is routed between the vertical wall and the window, hidden by a cover member, ensuring minimal visibility and enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the solar cell module is installed in the window to enable solar power generation, then solar power generation capability is improved, but the extraction wire becomes exposed and visible from the indoor side, deteriorating the appearance
Solution Approach 1:
The patent introduces a ceiling structure with a vertical wall part as an intermediary element to hide the extraction wire. The wire is routed between the vertical wall part and the window, using the ceiling structure as a mediator to conceal the wire from indoor views while maintaining electrical connectivity for solar power generation.
Solution Approach 2:
The patent utilizes the vertical dimension by routing the extraction wire upward between the window and the ceiling's vertical wall part. This dimensional approach allows the wire to be positioned in a three-dimensional space that is not visible from the horizontal indoor perspective, effectively hiding it while maintaining functionality.
2Reliability
If the extraction wire is exposed for solar cell module operation, then electrical connectivity is ensured, but the wire is visible from indoor side creating aesthetic and safety issues
Solution Approach 1:
The ceiling's vertical wall part serves as an intermediary structure that provides a concealed pathway for the extraction wire. This mediator allows the wire to maintain its electrical function while being hidden from indoor views, eliminating both aesthetic deterioration and safety concerns associated with exposed wiring.
Solution Approach 2:
The extraction wire is nested within the spatial relationship between the window and the ceiling's vertical wall part. This nesting approach places the wire within an existing structural cavity, concealing it while maintaining its electrical connectivity function.

Function Achieved in This Case
The solution effectively hides the extraction wire, improving the indoor appearance and safety while maintaining heat insulation and enabling efficient solar power generation.
Implementation Method 1
there is an increasing demand for solar power generation using an outer wall and a window
Implementation Method 2
both heat insulation of a window and solar power generation can be simultaneously realized by providing a gap inside an existing window glass
