Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-voltage power supplies are used to apply electrostatic attraction force, then foreign matter can be effectively collected, but device complexity and cost increase
Solution Approach 1:
The patent replaces the high-voltage electrical system with a mechanical triboelectric charging system. The charging member mechanically contacts the capturing member to generate static electricity through friction, eliminating the need for complex high-voltage power supplies while achieving effective foreign matter collection
Solution Approach 2:
The charging member generates its own charging electricity through triboelectric effect during the cleaning process. The system uses the relative motion between the charging member and capturing member to self-generate the electrostatic force needed for collection, without requiring external high-voltage power sources
2Reliability
If high-voltage power supplies are used, then electrostatic attraction can be achieved, but operational cost increases
Solution Approach 1:
The patent substitutes electrical energy consumption with mechanical energy. The triboelectric charging process converts mechanical friction between rotating members into electrostatic energy, eliminating continuous high-voltage power supply requirements and reducing operational energy costs
Solution Approach 2:
The system generates its own charging energy during operation through the relative motion of the charging member and capturing member. This self-generating approach eliminates the need for continuous external power supply, significantly reducing operational energy consumption

AI summary
A capturing rotation member captures an object on a surface by static electricity. A charging rotation member rotates while contacting with the capturing rotation member and triboelectrically charges a surface of the capturing rotation member. A collecting rotation member rotates while contacting with the capturing rotation member and collects the object adhering to the surface of the capturing rotation member. The capturing rotation member and the charging rotation member rotate in the same direction. The capturing rotation member and the collecting rotation member rotate in opposite directions.
