Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
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 due to diverse solar panel specifications
Solution Approach 1:
The patent replaces chemical and thermal decomposition methods with a mechanical cutting system. A cutting device with a cutting blade physically cuts through the base layer and solar cell unit to separate them from the cover layer, eliminating the need for complex chemical or thermal processes while maintaining effectiveness across diverse solar panel specifications
Solution Approach 2:
The cutting device is designed as a universal solution that can handle multiple solar panel specifications through programmable cutting paths and adjustable parameters. The system stores cutting parameters for different solar panel types and automatically selects appropriate parameters, making the same mechanical device effective across various panel designs without requiring multiple specialized systems
2Productivity
If physical removal by milling or grinding is used, then the base layer and solar cell unit can be removed, but the process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces time-consuming milling and grinding operations with a direct cutting method. The cutting blade efficiently slices through the base layer and solar cell unit in a single pass, dramatically reducing removal time compared to gradual material removal by milling or grinding, thereby significantly improving recycling productivity
Solution Approach 2:
The system performs preliminary identification and measurement of the solar panel dimensions and structure before the cutting operation. By capturing images and measuring the panel in advance, the system pre-determines the optimal cutting path and parameters, enabling the cutting device to execute the removal operation quickly and efficiently without delays during the actual cutting process
3Reliability
If automated removal is implemented without adaptive parameters, then the process can be standardized, but the cover layer may be damaged due to inability to adapt to different solar panel specifications
Solution Approach 1:
The system incorporates feedback through image capture and measurement devices that scan the solar panel before cutting. The captured data about panel dimensions, structure, and positioning is fed back to the control unit, which adjusts the cutting parameters and path accordingly. This feedback loop ensures the cutting device adapts to each specific panel while maintaining consistent protection of the cover layer
Solution Approach 2:
The cutting device is designed with dynamic capabilities, including adjustable cutting depth, variable cutting speed, and programmable cutting paths. These dynamic parameters allow the system to adapt to different solar panel specifications while maintaining reliable cover layer protection. The cutting blade can dynamically adjust its position and depth based on real-time measurements, ensuring precise separation without damaging the cover layer regardless of panel type
