Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual connection and irradiation testing is used for solar panels, then testing can be performed, but the process is time-consuming and costly
Solution Approach 1:
The cable contact area is pre-positioned and fixed to the junction box before testing, with precise spatial coordinates defined. This preliminary positioning eliminates the need for manual connection during testing, enabling automated robots to efficiently perform irradiation tests without time-consuming manual intervention
Solution Approach 2:
The patent introduces a testing device that serves as an intermediary between the solar panel and the testing process. This device automatically establishes electrical contact with the pre-positioned cable contact area, replacing manual connection operations and enabling efficient automated testing
2Extent of automation
If manual connection is used for cable attachment, then connection can be made, but the process requires manual handling and is inefficient
Solution Approach 1:
The cable contact area is designed to be self-positioning and self-fixing on the junction box. The contact area is permanently attached at predefined coordinates, eliminating the need for manual connection operations during testing. This self-service design enables complete automation of the testing process
Solution Approach 2:
The cable and its contact area are pre-assembled and fixed to the junction box before the testing process begins. This preliminary action defines the exact spatial position of the contact area, allowing automated testing devices to easily locate and establish electrical contact without manual intervention
