Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual water spraying is used to clean photovoltaic panels, then cleaning can be performed with simple equipment, but cleaning efficiency is low and uniformity cannot be ensured
Solution Approach 1:
The cleaning device is equipped with an automatic control system that enables self-service cleaning operations. The system automatically controls the water spray, brush roller, and suction fan without requiring manual operation, thereby significantly improving cleaning efficiency while maintaining manageable equipment complexity through automated workflows.
Solution Approach 2:
The cleaning device integrates multiple functions into a single unit: water spraying for wet cleaning, brush roller for mechanical scrubbing, and suction fan for water removal. This multi-functional design improves overall cleaning efficiency by addressing different cleaning needs simultaneously while consolidating equipment rather than requiring separate devices for each function.
2Manufacturing precision
If manual cleaning operation is used, then equipment cost is low, but cleaning uniformity cannot be ensured and some areas cannot be thoroughly cleaned
Solution Approach 1:
The device incorporates a control system that monitors and coordinates the operation of various components (water pump, brush roller motor, suction fan). This feedback mechanism ensures synchronized operation and consistent cleaning performance across different panel areas, achieving uniform cleaning quality while managing equipment complexity through centralized control.
Solution Approach 2:
The brush roller is designed to rotate dynamically during cleaning operations, adapting to the panel surface. The water spray system and suction fan also operate dynamically rather than statically, allowing the equipment to adjust to different cleaning conditions and maintain uniform cleaning quality across varying areas of the photovoltaic panels.
3Adaptability or versatility
If manual cleaning is used, then working setup is simple, but all-weather cleaning cannot be achieved due to weather and working time limitations
Solution Approach 1:
The automatic control system enables the device to operate independently without manual intervention during cleaning cycles. This self-service capability allows the equipment to function during conditions when manual operation would be impractical or impossible, such as adverse weather conditions or outside typical working hours, thereby achieving all-weather cleaning capability.
4Manufacturing precision
If cleaning liquid is sprayed onto the brush roller, then cleaning effect is enhanced, but residual liquid may remain on the panel surface
Solution Approach 1:
The suction fan acts as an intermediary component between the cleaning process and the panel surface. It actively removes excess cleaning liquid and debris from the panel after the brush roller applies the cleaning solution, preventing residual liquid from remaining on the surface while maintaining thorough cleaning effectiveness.
