Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixed-type solar cell panels are used, then installation simplicity is maintained, but power generation efficiency decreases due to contamination accumulation
Solution Approach 1:
The solar cell panel cleaning apparatus enables the solar cell panels to clean themselves by providing a self-mobile cleaning system that autonomously detects contamination and performs cleaning operations without requiring external intervention or manual cleaning, thus resolving the contradiction between maintaining installation simplicity and ensuring power generation efficiency
Solution Approach 2:
The contamination detection unit continuously monitors the solar cell panels before significant contamination occurs, enabling early detection and timely cleaning operations to prevent power generation efficiency degradation, thereby addressing the contradiction between reliability maintenance and contamination prevention
2Productivity
If conventional cleaning apparatuses are used, then device simplicity is maintained, but cleaning effectiveness and real-time large area coverage are insufficient
Solution Approach 1:
The cleaning apparatus is divided into functional modules including a contamination detection unit, a cleaning unit with fluid spray and brush components, and a self-mobile unit with driving mechanisms. Each module performs a specific function, enabling comprehensive large-area coverage while maintaining reasonable device complexity through modular design
Solution Approach 2:
The self-mobile cleaning apparatus integrates multiple functions into a single system: contamination detection, fluid spraying, brush cleaning, and autonomous movement. This multi-functional design enables real-time large area coverage and improved productivity without requiring multiple separate devices, thus resolving the contradiction between cleaning effectiveness and device complexity
3Loss of time
If manual cleaning methods are used, then device complexity is minimized, but real-time cleaning capability and large area efficiency are lost
Solution Approach 1:
The contamination detection unit provides real-time feedback on the contamination status of solar cell panels to the control unit, which automatically activates the cleaning mechanisms when contamination is detected, enabling real-time cleaning response and eliminating the time loss associated with manual inspection and cleaning scheduling
Solution Approach 2:
The system performs automatic contamination detection and cleaning operations without human intervention, with the self-mobile unit autonomously navigating to contaminated areas and executing cleaning tasks, thereby achieving real-time cleaning capability and resolving the contradiction between automation extent and time loss
