Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dust-filtering bag or filter is used to separate dry matter from the suction airflow, then dry vacuuming is effective, but fine particles of dry dust are not effectively separated and suction power is rapidly lost due to dust accumulation
Solution Approach 1:
The invention changes the physical state of the separation medium from dry (filter/bag) to liquid (water). By introducing water into the suction airflow, the system achieves superior separation of fine dry dust particles through liquid attraction, preventing the suction power loss that occurs with traditional dry filters due to dust accumulation
Solution Approach 2:
Water acts as an intermediary substance between the suction airflow and the separator. The liquid delivery device introduces water into the airflow, which then mediates the separation process by attracting fine dust particles, enabling effective separation without the clogging problems of traditional dry filters
2Adaptability or versatility
If the cleaner is adapted for wet mode with a liquid tank and delivery system, then wet cleaning and surface cleaning are enabled, but the cleaner requires user adaptation and configuration changes
Solution Approach 1:
The cleaner is designed with universal functionality to handle both wet and dry materials effectively. The liquid delivery device and cyclonic separator work together to create a system that can process spilled liquids, fine dry dust, and wetted surfaces without requiring fundamental configuration changes or user adaptation
Solution Approach 2:
The system automatically manages the liquid delivery and separation processes. The liquid delivery device selectively introduces water into the suction airflow based on operational needs, and the cyclonic separator automatically separates the liquid-matter mixture, reducing the need for user intervention and configuration changes
