Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional aqueous cleaning methods are used, then cleaning performance is achieved, but water consumption is high
Solution Approach 1:
The invention changes the cleaning medium from liquid (water) to solid particles, fundamentally altering the physical state parameter. Solid particles are used instead of aqueous solutions, enabling effective cleaning with minimal or no water, thus resolving the contradiction between water consumption and cleaning performance
Solution Approach 2:
The invention replaces the chemical/aqueous cleaning mechanism with a mechanical cleaning mechanism using solid particles. The particles physically interact with the substrate surface through abrasion and impact, substituting the conventional water-based chemical cleaning process
2Ease of operation
If conventional cleaning apparatus with multiple moving components are used, then cleaning function is provided, but device complexity increases
Solution Approach 1:
The invention extracts and eliminates unnecessary moving components from the cleaning apparatus. By using a stationary drum with integrated flow paths, complex mechanisms such as external pumps, valves, and moving parts are removed, simplifying the overall device structure while maintaining cleaning functionality
Solution Approach 2:
The invention merges multiple functions into a single integrated drum structure. The drum combines storage, dispensing, and collection functions with built-in flow paths, eliminating the need for separate external components and reducing overall device complexity
3Productivity
If unidirectional collecting flow path is used, then solid particle collection is achieved, but collection efficiency is reduced and substrate tangling increases
Solution Approach 1:
The invention introduces asymmetry through bidirectional flow paths that adapt to rotation direction. The flow paths are designed to work effectively in both clockwise and counter-clockwise rotations, creating symmetric functionality from asymmetric path designs, which improves collection efficiency while preventing substrate tangling
Solution Approach 2:
The invention makes the collection system dynamic by designing flow paths that automatically adapt to the direction of drum rotation. The bidirectional flow paths enable the system to function optimally regardless of rotation direction, enhancing collection efficiency and reducing substrate tangling through dynamic adaptation
