Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filtering member with small pores (50-100 μm) is used to filter microorganisms, then microorganisms can be filtered, but clogging occurs periodically requiring maintenance stops
Solution Approach 1:
The patent replaces the conventional mechanical filtering system with a blade-driven micro-pulverization system. Instead of using a filtering member with small pores that clogs, the invention uses rotating blades to mechanically pulverize and destroy microorganisms through high-speed rotation (800-1200 rpm), applying mechanical shock and cutting forces that effectively eliminate microorganisms without creating clogging-prone pore structures.
Solution Approach 2:
The patent changes the fundamental operating parameter from filtration (passive pore-based separation) to mechanical pulverization (active high-speed rotation). The blade rotating body rotates at 800-1200 rpm, creating intense mechanical shear forces and shock waves that destroy microorganisms. This parameter change from static filtration to dynamic pulverization eliminates the clogging issue inherent in pore-based filtering.
2Manufacturing precision
If the filtering member pores are made smaller to filter ultra microorganisms, then filtering precision improves, but the device size must become greatly large to handle 500-3000 tons of ballast water per hour
Solution Approach 1:
The patent replaces the space-intensive pore-based filtration system with a compact blade pulverization system. The rotating blades cut and pulverize microorganisms through mechanical action, achieving effective removal without requiring the large surface area needed for high-flow-rate filtration. This mechanical approach is inherently more space-efficient while maintaining the ability to handle 500-3000 tons of ballast water per hour.
Solution Approach 2:
The patent introduces dynamic high-speed rotation (800-1200 rpm) to create intense local mechanical forces that effectively destroy microorganisms. This dynamic pulverization process is much more space-efficient than static filtration, as the high-speed rotating blades generate sufficient shear and shock forces to kill ultra microorganisms without requiring large filtering surfaces.
3Reliability
If conventional filtering members are used, then microorganisms can be filtered, but ultra microorganisms with sizes less than 50 μm cannot be filtered
Solution Approach 1:
The patent replaces pore-based filtration with blade-driven mechanical pulverization. The high-speed rotating blades (800-1200 rpm) apply intense mechanical shear forces and shock waves that destroy ultra microorganisms regardless of their size. This mechanical destruction approach is superior to pore filtration for ultra microorganisms, as the blade action directly impacts and fragments them before they can pass through any theoretical filter pore.
Solution Approach 2:
The patent changes the removal mechanism from passive pore separation to active mechanical destruction. By rotating blades at 800-1200 rpm, the system creates sufficient mechanical force to shatter and eliminate ultra microorganisms with sizes less than 50 μm. This parameter change from filtration to pulverization enables effective removal of the smallest microorganisms that would be impossible to filter through conventional pore-based systems.
4Reliability
If high-concentration chemicals are used to kill ultra microorganisms, then disinfection effectiveness improves, but additional neutralizing devices are required to remove residual chemicals
Solution Approach 1:
The patent replaces chemical disinfection with mechanical pulverization. The high-speed rotating blades physically destroy ultra microorganisms through mechanical shock and cutting forces, eliminating the need for high-concentration chemicals. This mechanical approach achieves complete microorganism removal without introducing chemical residues that would require neutralizing equipment.
Solution Approach 2:
The patent converts the harmful effect of mechanical blade rotation into a beneficial destruction mechanism. The high-speed rotation (800-1200 rpm) that could potentially cause damage is instead harnessed to create intense mechanical shock and shear forces that selectively destroy microorganisms. This approach eliminates chemical disinfection needs while achieving complete microorganism removal, thereby removing the need for neutralizing equipment.
