Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnetic bar has magnetism to adsorb magnetic impurities, then the filtering function is improved, but the cleaning operation requires power-off which reduces working efficiency
Solution Approach 1:
The magnetic bar is divided into multiple magnetic rollers, each with independent magnetic regions and non-magnetic regions. This segmentation allows different parts of the system to perform different functions simultaneously - some regions adsorb impurities while other regions enable cleaning without power-off
Solution Approach 2:
The magnetic rollers have local quality differentiation with specific magnetic regions and non-magnetic regions. The non-magnetic regions are positioned where scrapers contact the rollers, allowing scrapers to remove adsorbed impurities without interference from magnetic forces in those local areas
2Reliability
If the magnetic bar adsorbs magnetic impurities continuously, then the purification function is improved, but the accumulated impurities require periodic cleaning which interrupts operation
Solution Approach 1:
The system enables continuous operation by allowing impurity removal to occur simultaneously with the filtering process. The scrapers continuously remove adsorbed impurities from the non-magnetic regions of the rotating magnetic rollers, eliminating the need for periodic power-off cleaning interruptions
Solution Approach 2:
The magnetic rollers perform self-cleaning through the scraper mechanism. As the rollers rotate, the scrapers automatically remove accumulated impurities from the non-magnetic regions, allowing the system to maintain its filtering capability without external intervention or power interruption

AI summary
A fully automatic magnetic filter includes an apparatus barrel, magnetic rollers, scrapers, and a motor. The number of the magnetic rollers is four and corresponds to the number of the scrapers. The magnetic rollers are located in the apparatus barrel, and each includes an outer layer and an inner core. The outer layer is sleeved onto the inner core. The inner core has a magnetic region and a non-magnetic region. The outer layers of the magnetic rollers are driven and connected through a gear. The outer layer of one of the magnetic rollers is connected with the motor and driven by the motor. Each scraper corresponds to the outer layer of a corresponding one of the magnetic rollers. When the iron filings adsorbed on the outer layer are rotated to the non-magnetic region, the iron filings can be scraped off by the scrapers.
