Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cleaning methods are used, then the cleaning process is simple, but the cleaning efficiency and safety are insufficient
Solution Approach 1:
The patent combines multiple cleaning functions (brushing, vacuum suction, ionized air treatment) into a single integrated cleaning assembly that moves across the photovoltaic panel surface. The housing contains all components (drive motor, vacuum pump, air pump, ionizing electrode, brush) in one unit, allowing simultaneous execution of multiple cleaning operations to improve overall cleaning efficiency while maintaining manageable device complexity.
Solution Approach 2:
The cleaning assembly is designed as a multi-functional device that performs brushing, vacuum suction, and ionized air treatment all in one unit. This universal design allows the same assembly to handle various types of debris (dust, dirt, bird droppings) through different mechanisms, improving cleaning efficiency across diverse contamination scenarios without requiring multiple separate devices.
2Object-generated harmful factors
If only mechanical brushing is used, then the device structure is simple, but debris removal effectiveness is limited
Solution Approach 1:
The patent merges mechanical brushing with vacuum suction in a single cleaning assembly. The brush mechanically loosens and breaks up debris while the vacuum pump simultaneously sucks away the loosened particles through the suction head. This combination of mechanical and pneumatic actions significantly improves debris removal effectiveness compared to brushing alone, while the integrated design keeps the overall structure manageable.
Solution Approach 2:
The vacuum pump and air pump components utilize pneumatic principles to enhance debris removal. The vacuum pump creates negative pressure to suction loose debris away from the panel surface, while the air pump generates ionized air that helps dislodge and remove stubborn contaminants. These pneumatic mechanisms work in conjunction with the mechanical brush to achieve superior cleaning performance.
3Reliability
If conventional cleaning is used, then energy consumption is low, but cleaning thoroughness and panel safety are compromised
Solution Approach 1:
The ionizing electrode acts as an intermediary that treats the air before it contacts the panel surface. By ionizing the air, the system creates a controlled environment that enhances cleaning effectiveness while protecting the panel. The ionized air helps neutralize static charges and prevents damage from direct mechanical contact, improving panel safety despite the additional energy required for ionization.
Solution Approach 2:
The system performs preliminary ionization of air before the cleaning process completes. The ionizing electrode treats the air in advance, creating a protective atmosphere that enhances the effectiveness of subsequent mechanical and pneumatic cleaning actions. This preliminary treatment helps prevent damage to the panel surface while improving overall cleaning thoroughness.
