Solution Overview
Problem
Conventional methods for manufacturing particles, such as polymer and inorganic particles, face challenges in producing uniformly sized, high-purity particles due to batch processes that result in non-uniform size distribution, low purity, and unsuitable apparatus designs for continuous production.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If batch process is used for particle manufacturing, then flexibility in processing different materials is maintained, but particle size uniformity and purity deteriorate
Solution Approach 1:
The manufacturing process is segmented into multiple sequential reactors (first reactor for nucleation, second reactor for crystallization). This segmentation allows each reactor to perform a specific function, ensuring uniform particle size while maintaining the ability to process different materials by adjusting parameters in each stage.
Solution Approach 2:
The invention transitions from batch process to continuous process by connecting multiple reactors in sequence with continuous material feed. This continuous action ensures consistent particle formation and improves both uniformity and purity without sacrificing processing flexibility.
2Device complexity
If batch reactor is used, then process simplicity is maintained, but productivity and particle purity deteriorate
Solution Approach 1:
The process is divided into sequential reaction stages in different reactors, allowing continuous operation while maintaining manageable complexity through modular design. Each reactor performs a specific function, simplifying the overall process control.
Solution Approach 2:
The first reactor performs preliminary nucleation before the second reactor completes crystallization. This preliminary action in a dedicated stage improves overall productivity and particle purity while maintaining process simplicity through clear functional separation.
3Device complexity
If single reactor is used, then device complexity is reduced, but particle dispersion uniformity and purity deteriorate
Solution Approach 1:
The reaction process is segmented into nucleation (first reactor) and crystallization (second reactor) stages. This segmentation achieves uniform particle dispersion and high purity by controlling each stage separately, while the modular design keeps device complexity manageable.
Solution Approach 2:
The first reactor acts as an intermediary stage that prepares uniformly nucleated particles before they enter the second reactor for final crystallization. This intermediary step is crucial for achieving uniform dispersion and high purity without excessive device complexity.
4Device complexity
If conventional particle formation method is used, then process simplicity is maintained, but particle surface uniformity and purity deteriorate
Solution Approach 1:
The particle formation process is segmented into nucleation and crystallization stages in separate reactors. This segmentation enables uniform particle surfaces by controlling crystal growth in the second reactor after uniform nucleation in the first reactor, maintaining reasonable process structure.
Solution Approach 2:
Uniform nucleation is achieved as a preliminary action in the first reactor before particles enter the second reactor for controlled crystallization. This preliminary uniformity is essential for achieving smooth particle surfaces and high purity without overly complex processing.
