Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional machinery equipment circulates crude liquid with suspended impurities for oil sludge removal, then oil sludge can be moved and treated, but the delivery pipes and pumps are damaged or malfunction due to long-term circulation
Solution Approach 1:
The system divides the oil sludge treatment process into multiple stages: initial circulation with laundry detergent carrier to loosen sludge, then separation into clarified liquid and crude liquid, followed by selective circulation of clarified liquid through the oil tank. This segmentation allows the system to handle impurities at different stages, protecting equipment from continuous exposure to suspended impurities while maintaining oil sludge removal capability.
Solution Approach 2:
The patent introduces clarified liquid as an intermediary substance that circulates through the oil tank to loosen and suspend oil sludge, replacing the need to circulate crude liquid with suspended impurities through the delivery pipes and pumps. The clarified liquid serves as a clean carrier that achieves the same function of moving oil sludge without causing equipment damage.
2Productivity
If conventional equipment uses crude liquid as carrier to move oil sludge, then oil sludge can be transported, but unclean quality adversely affects work period and quality control
Solution Approach 1:
The patent uses clarified liquid as an intermediary carrier substance that is free from suspended impurities. This clarified liquid circulates through the oil tank to loosen and transport oil sludge, providing the same transport function as crude liquid but without the quality control issues. The clarified liquid acts as a clean medium that maintains work period and quality control standards.
3Ease of operation
If conventional machinery equipment circulates crude liquid containing suspended impurities, then oil sludge can be moved into crude oil tank, but components are damaged due to long-term circulation
Solution Approach 1:
The patent introduces clarified liquid as a clean intermediary carrier that performs the function of transferring and loosening oil sludge without containing suspended impurities. This clarified liquid circulates through the oil tank and delivery pipes, achieving easy operation for oil sludge transfer while avoiding the harmful effects of suspended impurities on equipment components.
Solution Approach 2:
The system separates and discards the clarified liquid from the crude liquid containing suspended impurities. The clarified liquid is recovered and reused as the carrier for oil sludge transfer, while the crude liquid with impurities is separated and not circulated through the delivery pipes and pumps, thereby preventing equipment damage from suspended impurities.
