Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batch synthesis and traditional discovery processes are used, then products can be prepared and tested, but the process is time-consuming and inefficient
Solution Approach 1:
The patent implements continuous flow synthesis that operates without interruption, allowing reactions to proceed continuously through the system. This eliminates the batch-wise stop-and-go nature of traditional methods, maintaining continuous productive action from reactant introduction through product formation and analysis, thereby dramatically improving discovery efficiency and reducing time loss.
Solution Approach 2:
The patent merges multiple functions into an integrated flow system where synthesis, separation, purification, and analysis occur in a unified continuous process. By combining these previously separate batch operations into a single integrated flow platform, the system eliminates transfer times and intermediate processing steps, resolving the contradiction between productivity and time consumption.
2Adaptability or versatility
If genetic algorithms are used to optimize existing products, then product improvement can be achieved, but exploration of diverse structural and compositional variations is limited
Solution Approach 1:
The patent employs dynamic control of flow parameters including variable flow rates, adjustable reaction times, and real-time parameter optimization. This dynamic capability allows the system to adaptively explore diverse product spaces by continuously adjusting conditions, enabling versatile structural and compositional variation exploration while managing system complexity through automated control.
Solution Approach 2:
The patent systematically varies multiple parameters including flow rates, temperatures, pressures, and reagent concentrations to explore diverse product space. By implementing controlled parameter changes across multiple dimensions simultaneously, the system achieves high adaptability in generating structural and compositional variations while the automated flow platform manages the complexity of coordinating these parameter changes.
3Measurement precision
If multiple products are prepared individually and tested, then useful products can be identified, but the process requires preparation of many products with individual analysis
Solution Approach 1:
The patent implements continuous online analysis where products are characterized immediately as they are formed in the flow system. This continuous measurement approach maintains high precision by analyzing products under consistent conditions without batch interruptions, while simultaneously achieving high throughput by eliminating the sequential prepare-analyze-repeat cycle of traditional methods.
Solution Approach 2:
The patent incorporates real-time feedback from online analytical measurements to control and optimize product formation. The continuous analytical data feeds back to adjust flow parameters and reaction conditions, maintaining measurement precision through adaptive control while improving productivity by directing synthesis toward desired products and eliminating unnecessary preparative steps.
