Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If rotating roller brushes are used to clean railway vehicles, then cleaning function is provided, but water and detergent consumption is significant
Solution Approach 1:
The washing system divides the cleaning function into discrete magnetic applicators that are dispersed throughout the washing fluid, replacing the single large roller brush with multiple small magnetic cleaning elements that can be distributed across the entire vehicle surface
Solution Approach 2:
The system replaces the mechanical rotation of roller brushes with a magnetic field-based propulsion system. Magnetic applicators are moved along the vehicle body by a magnetic field generator, eliminating the need for mechanical rotating components and reducing water consumption associated with traditional brush systems
2Loss of substance
If rotating roller brushes are used to clean railway vehicles, then cleaning function is provided, but detergent product consumption is significant
Solution Approach 1:
The magnetic applicators are designed to be recovered and reused after washing. The recovery system separates magnetic applicators from the washing fluid using magnetic fields, allowing the same applicators to be reused multiple times, thereby reducing detergent consumption and waste generation
Solution Approach 2:
The system changes the physical state of the washing fluid to a foamed structure, which increases the concentration of detergent in the foam bubbles while reducing overall fluid volume. This foam-based washing approach reduces detergent consumption compared to traditional liquid detergent systems
3Loss of substance
If magnetic applicators are used with magnetic field generator, then water and detergent consumption is reduced, but device complexity increases
Solution Approach 1:
The magnetic field generator serves multiple functions: it propels magnetic applicators along the vehicle body, recovers applicators by attracting them back to the system, and controls the movement patterns of applicators. This multi-functionality reduces the need for separate mechanical components, actually simplifying the overall system despite the introduction of magnetic fields
4Productivity
If magnetic applicators are used to clean vehicle body, then cleaning efficiency is enhanced, but applicator retrieval and separation requires additional systems
Solution Approach 1:
The recovery system uses magnetic fields instead of mechanical filtration or separation mechanisms. The magnetic field generator attracts magnetic applicators back to the system, providing a simple and efficient retrieval method that does not require complex mechanical separation equipment
