Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional parallel flow paths are used in separators, then the structure is simple and easy to manufacture, but the fluid flow distribution is poor and pressure drop is high
Solution Approach 1:
The patent applies curvature by designing streamlined walls with non-parallel configurations instead of conventional straight parallel walls. The curved/streamlined shape of the walls optimizes fluid flow patterns, reduces turbulence, and lowers pressure drop while maintaining manufacturing feasibility through standard forming processes.
Solution Approach 2:
The patent introduces asymmetry by using non-parallel streamlined walls where at least two walls have different orientations or positions. This asymmetric configuration creates optimized flow distribution patterns that improve fluid efficiency and reduce pressure drop compared to symmetric parallel wall structures.
2Productivity
If non-parallel streamlined walls are used to optimize fluid flow, then fluid flow efficiency improves, but the device complexity increases
Solution Approach 1:
The streamlined curved walls provide optimized fluid flow paths that improve efficiency while the curvature can be achieved through standard manufacturing processes, limiting the increase in device complexity to only the geometric configuration rather than structural complexity.
Solution Approach 2:
The non-parallel streamlined walls create locally optimized flow conditions in specific regions of the separator. Each wall segment is designed with specific curvature and positioning to address local flow requirements, improving overall fluid efficiency without requiring complete redesign of the entire separator structure.
