Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sieve is used to sieve microparticles, then microparticle size uniformity is improved, but manufacturing precision of the sieve micropores cannot be controlled
Solution Approach 1:
The invention divides the sieve structure into multiple plate units, each with through holes of precise sizes. By segmenting the filtration function across multiple plates with controlled through holes rather than relying on a single woven sieve, the system achieves precise control over microparticle size separation while maintaining size uniformity.
Solution Approach 2:
The invention changes the structural parameters of the filtration system by using plate units with specifically designed through hole diameters. The plate units have controlled geometric parameters (through hole size, spacing) that enable precise micropore size control, unlike conventional woven sieves where micropore sizes cannot be precisely controlled.
2Reliability
If a sieve is used for microparticle filtration, then filtration accuracy is improved, but the micropores become blocked after a period of time
Solution Approach 1:
The invention introduces a tangential flow mechanism that creates dynamic fluid motion across the plate units. The flow direction is tangent to the plate surfaces, creating continuous movement that prevents particles from settling and blocking the through holes. This dynamic flow pattern maintains filtration accuracy over extended periods while preserving filtration efficiency.
Solution Approach 2:
The tangential flow filtration system maintains continuous useful action by keeping the fluid in constant motion across the filtration surfaces. This continuous dynamic flow prevents particle accumulation and blockage, ensuring that the filtration system operates efficiently and reliably over extended periods without degradation in performance.
3Ease of manufacture
If a conventional sieve structure is used, then assembly is simple, but disassembly and maintenance are difficult
Solution Approach 1:
The invention segments the filtration system into multiple independent plate units that can be easily assembled and disassembled. Each plate unit is a separate module that can be individually removed, inspected, and maintained. This modular segmentation simplifies both assembly during manufacturing and disassembly for maintenance compared to conventional integrated sieve structures.
Solution Approach 2:
The plate units are designed as universal modules that can be easily assembled in series to form the filtration system. The same modular plate unit design serves multiple functions: filtration, easy assembly, and simplified maintenance. This universal modular approach makes the system equally easy to manufacture and maintain.
