Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional chemical or thermal decomposition methods are used to remove the base layer and solar cell unit, then the removal process can be performed, but the process becomes complex and difficult to automate across 17,000+ solar panel specifications
Solution Approach 1:
The patent segments the recycling process into distinct stages: scanning the product label to identify solar panel specifications, determining appropriate removal parameters based on the identified specifications, and executing the removal process with customized parameters. This segmentation allows the system to handle diverse solar panel types through a standardized framework, improving automation while managing complexity.
Solution Approach 2:
The patent implements dynamic parameter adjustment where the removal parameters (such as cutting depth, speed, and path) are automatically determined based on the specific solar panel model identified through label scanning. This dynamic adaptation enables the same equipment to efficiently process over 17,000 different specifications without requiring manual reconfiguration for each type.
2Productivity
If physical removal by milling or grinding is used, then the base layer and solar cell unit can be removed, but the cover layer may be damaged
Solution Approach 1:
The patent performs preliminary scanning and identification of the solar panel's product label before the removal process. This preliminary action determines the specific removal parameters needed for that particular panel type, allowing the system to pre-calculate the precise cutting depth and path that will remove the base layer and solar cell unit while stopping exactly at the cover layer boundary, thus preventing damage while maintaining high productivity.
Solution Approach 2:
The patent changes the removal parameters (depth, speed, tool path) based on the identified solar panel specifications. By adjusting these parameters dynamically, the system optimizes the removal process for each panel type to maximize efficiency while precisely controlling the cutting depth to protect the cover layer integrity.
3Adaptability or versatility
If manual recycling methods are used for diverse solar panel specifications, then each panel can be processed individually, but the recycling process becomes time-consuming and inefficient
Solution Approach 1:
The patent implements a self-service system where the solar panel's own product label provides the identification information needed to determine the correct removal parameters. The scanning device automatically reads the label, the system autonomously determines the appropriate processing parameters based on the identified specifications, and executes the removal without human intervention. This self-service approach enables the system to adapt to any of the 17,000+ solar panel specifications while maintaining high-speed automated processing.
