Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If continuous flow modules are arranged in a fixed linear sequence, then the device structure is simple, but the device cannot perform convergent or divergent syntheses and lacks versatility
Solution Approach 1:
The device divides the synthesis process into independent continuous flow modules, each capable of performing a specific reaction step. These modules can be individually selected and arranged in different sequences (linear, convergent, or divergent) depending on the synthetic requirements, enabling flexibility without increasing overall device complexity.
Solution Approach 2:
The valve assembly serves as a universal interface that can connect any continuous flow module to any other module or to the reagent supply system. This multi-functional connection system allows the same device structure to support multiple synthesis modes (linear, convergent, divergent) and different reaction sequences, greatly enhancing adaptability.
2Reliability
If separate reactor modules are used for each reaction step, then each reaction can be optimized independently, but the number of modules is limited and the system becomes complex
Solution Approach 1:
The device employs dynamic valve control to change the flow path and module arrangement during operation. The same physical modules can be reconfigured into different sequences (linear, convergent, or divergent) by changing valve positions, allowing independent optimization of reaction conditions while avoiding the need for a large number of fixed modules.
Solution Approach 2:
The system changes operational parameters (flow paths, module sequences, connection topologies) rather than physically reconfiguring the device structure. By controlling valve positions and flow rates, the same hardware can perform multiple synthesis modes, reducing the number of physical modules needed while maintaining reaction optimization capability.
3Adaptability or versatility
If the device is designed for a specific reaction type, then the device structure is simplified, but the device cannot perform other reaction sequences
Solution Approach 1:
The valve assembly and module interface are designed with universal compatibility, allowing any continuous flow module to be connected to any other module or to the reagent supply. This universal design enables the device to perform various reaction types (linear, convergent, divergent syntheses) without physical reconfiguration, maintaining ease of operation while maximizing adaptability.
