Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate junction boxes and interconnections are used for solar cell modules, then electrical connection is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the junction box and interconnection functions into the panel structure itself. The attachment parts serve dual purposes: mechanical connection between panels and electrical connection through integrated positive and negative electrodes. This eliminates separate junction boxes and complex wiring systems while maintaining reliable electrical connectivity.
Solution Approach 2:
The attachment parts are designed with multi-functionality, serving both as mechanical fastening elements and as electrical conductors. The first and second attachment parts with integrated electrodes perform both structural support and electrical connection functions, reducing the need for separate specialized components.
2Reliability
If separate junction boxes are installed on roof panels, then solar energy collection is enabled, but installation difficulty increases due to complex wiring
Solution Approach 1:
The patent combines mechanical attachment and electrical connection functions into a single integrated structure. The attachment parts with embedded electrodes eliminate the need for separate wiring operations during installation, allowing workers to simply connect panels together without handling complex electrical connections.
Solution Approach 2:
The panel structure performs self-connection through its design. When panels are mechanically attached using the first and second attachment parts, the electrical connections are automatically established through the integrated electrodes, eliminating the need for separate electrical wiring operations.
3Power
If conventional solar cell modules are installed on building exteriors, then power generation is achieved, but manufacturing cost increases due to multiple components
Solution Approach 1:
The patent merges multiple components (junction box, interconnections, attachment hardware) into a single integrated panel structure. This reduction in component count directly lowers manufacturing costs while maintaining the power generation capability through the integrated solar cell modules.
Solution Approach 2:
The attachment parts are designed to perform multiple functions simultaneously: mechanical fastening, structural support, and electrical conduction. This multi-functionality reduces the total number of components needed, thereby reducing manufacturing costs while maintaining full power generation capability.
