Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the volume fraction of highly supersaturated regions is increased to promote particle precipitation, then particle production efficiency is improved, but particle quality deteriorates due to roughness and growth ring-like structures
Solution Approach 1:
The invention divides the single discharge port into multiple discharge ports, segmenting the raw material liquid flow into multiple streams. This segmentation reduces the volume fraction of highly supersaturated regions near each discharge port while maintaining overall precipitation efficiency, thereby preventing particle roughness and growth ring structures.
Solution Approach 2:
The invention introduces a baffle to create localized flow patterns that control the distribution of supersaturated regions. The baffle modifies the local flow field to reduce the volume fraction of highly supersaturated regions in specific areas, ensuring uniform particle precipitation and improving particle quality without sacrificing overall productivity.
2Device complexity
If conventional single discharge port design is used, then device complexity is reduced, but particle quality becomes inconsistent and production efficiency decreases
Solution Approach 1:
The invention segments the discharge port into multiple discharge ports arranged in a specific pattern. This segmentation improves particle characteristic consistency by reducing the volume fraction of highly supersaturated regions, while the modular design maintains reasonable device complexity.
Solution Approach 2:
The baffle acts as an intermediary element that mediates the flow between the multiple discharge ports and the reaction zone. It controls the flow field to ensure uniform distribution of supersaturated regions, thereby improving particle quality consistency without significantly increasing device complexity.
3Manufacturing precision
If high agitation speed is used to reduce supersaturated region volume, then particle quality is improved, but energy consumption increases
Solution Approach 1:
The invention changes the geometric parameters of the discharge ports (number, position, discharge amount) to control the volume fraction of highly supersaturated regions. This parameter optimization achieves particle quality improvement without requiring excessive agitation energy, as the structural design itself contributes to flow control.
Solution Approach 2:
The multiple discharge port configuration and baffle design create self-regulating flow patterns that naturally reduce the volume fraction of highly supersaturated regions. The system utilizes the inherent flow dynamics generated by the discharge ports themselves, reducing the need for high-energy agitation while maintaining particle quality.
