Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional filtration systems are used without chemical rinsing capability, then the system structure remains simple, but membrane cleaning efficiency and performance maintenance are insufficient
Solution Approach 1:
The system is divided into separate functional modules: a cleaning branch with dosing feeders for chemical injection, a circulation pump for fluid movement, and the main filtration module. This segmentation allows the chemical rinsing function to be added independently without redesigning the entire system, maintaining simplicity while improving membrane cleaning capability and performance reliability
Solution Approach 2:
The circulation pump and cleaning branch are designed to serve multiple functions: they can circulate cleaning chemicals through the membrane, distribute chemicals via dosing feeders, and integrate with the existing filtration system's inlet and outlet pipes. This multi-functionality improves membrane maintenance capability without proportionally increasing system complexity
2Productivity
If chemical rinsing operation is implemented, then membrane cleaning efficiency improves, but system complexity and operational procedures increase
Solution Approach 1:
The system includes pre-installed dosing feeders in the cleaning branch that are ready for chemical injection, and a circulation pump that can be activated to distribute cleaning chemicals. These components are prepared in advance, allowing rapid initiation of chemical rinsing operations without complex setup procedures, thus improving cleaning efficiency while keeping operational complexity manageable
Solution Approach 2:
The circulation pump automatically circulates cleaning chemicals through the membrane and back through the dosing feeders, creating a self-sustaining chemical rinsing cycle. Once initiated, the system maintains its own cleaning operation without requiring continuous manual intervention, improving productivity while minimizing operational complexity
