Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional ultrafiltration membrane method is used, then purification process is simplified, but impurity elimination is insufficient and resin overload occurs reducing reuse cycle
Solution Approach 1:
The purification process is divided into multiple sequential stages: ultrafiltration membrane filtration first removes large molecules, followed by activated carbon adsorption for intermediate impurities, and finally non-polar highly porous resin for trace impurities. This segmented approach achieves comprehensive purification while preventing resin overload by distributing the purification load across different media.
Solution Approach 2:
Different purification media are selected for different purification needs at different stages. The ultrafiltration membrane handles bulk removal, activated carbon handles colored impurities, and the non-polar resin handles trace impurities. Each medium is optimized for its specific function, achieving high overall purification efficiency.
2Manufacturing precision
If heating reaction solution to 95-100 C with active carbon is applied, then purification capacity is increased, but unstable indole rings form and decomposed discolored substances increase
Solution Approach 1:
The ultrafiltration membrane and activated carbon treatments are performed before the final resin purification step, removing bulk and colored impurities in advance. This preliminary action reduces the impurity load on subsequent steps, allowing milder processing conditions that prevent decomposition and discoloration.
Solution Approach 2:
The multi-stage purification process operates continuously with each stage preparing the solution for the next. The gradual removal of impurities through sequential stages maintains solution stability throughout the process, avoiding sudden changes that could cause decomposition.
3Ease of operation
If conventional batch purification method is used, then process control is simple, but production rate is low and recovery rate is reduced
Solution Approach 1:
The purification system is designed as a continuous flow process where solutions move sequentially through ultrafiltration, activated carbon, and resin columns without batch interruptions. This continuous operation maintains constant production rate while the automated flow control system keeps operation simple and manageable.
Solution Approach 2:
The same multi-stage purification system can handle different types of organic materials and tryptophan solutions with consistent high efficiency. The system's universal design allows it to maintain simple operation across various applications while achieving high productivity through continuous processing.
4Manufacturing precision
If ultrahigh purification of 99.9% or greater is achieved, then organic material quality for OLED is improved, but process complexity increases
Solution Approach 1:
The complex purification requirement is broken into three manageable sequential stages, each handling a specific range of impurities. This segmentation achieves the difficult 99.9%+ purity target while keeping each individual stage relatively simple and well-understood.
Solution Approach 2:
The system uses a composite purification approach combining three different types of purification media (membrane, activated carbon, resin) with complementary mechanisms. This composite strategy achieves ultrahigh purity by leveraging the strengths of each material type while distributing the overall system complexity across multiple components.
