Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a computer serves as a processing unit and user interface for controlling the chromatography system and presenting data, then data presentation capability is improved, but user interaction capability and system state determination remain limited
Solution Approach 1:
The system divides information presentation into separate functional modules: a process picture module displaying visual representation of system components and their states, a chromatogram module displaying separation data, and a fraction collection module displaying collection status. This segmentation allows users to access specific information types without overwhelming the interface, improving both information completeness and ease of operation.
Solution Approach 2:
The process picture provides real-time visual feedback about system component states (pump running status, valve positions, detector status, fraction collector status). Users can immediately see the current state of the chromatography system and make decisions based on this feedback, enhancing both information availability and operational ease.
2Loss of information
If the system presents basic chromatogram data and process pictures, then data visualization is improved, but comprehensive system state determination and control capability deteriorate
Solution Approach 1:
The process picture serves multiple functions simultaneously: it displays system component locations, shows real-time operational status of each component, provides control interfaces for user interactions, and presents fraction collection information. This multi-functionality allows a single visualization to provide comprehensive system state determination and control capability.
Solution Approach 2:
The system adds a spatial dimension to data presentation by displaying the physical layout of chromatography components in the process picture. This spatial representation complements the temporal chromatogram data, providing a two-dimensional information space that enhances both visualization comprehensiveness and control versatility.
3Device complexity
If fraction collection is performed without real-time parameter monitoring, then system simplicity is maintained, but user decision-making capability and control efficiency deteriorate
Solution Approach 1:
The fraction collector operates with a degree of autonomy by automatically collecting fractions based on pre-programmed parameters and real-time detector signals. The system monitors its own operation status and provides this information to the user through the process picture, reducing the need for constant user intervention while maintaining high decision-making efficiency.
Solution Approach 2:
The system replaces manual monitoring and decision-making with automated electronic sensing and control. Detectors continuously monitor the chromatographic effluent, and the control system automatically determines when to switch fraction collection based on detected peaks, substituting mechanical/manual operations with electronic automation to improve productivity without excessive complexity.
