Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-angle light scattering measurement is implemented for real-time molecular weight measurement, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: a flow cell for sample introduction, a read head with multiple detectors for light scattering measurement, and a skid attachment for integration. This segmentation allows each component to be optimized independently while maintaining overall system functionality for real-time molecular weight measurement.
Solution Approach 2:
The read head is designed to perform multiple functions: it measures light scattering at multiple angles simultaneously and can accommodate different flow cell configurations. This multi-functionality reduces the need for separate measurement systems, thereby managing device complexity while maintaining comprehensive measurement capability.
2Productivity
If real-time measurement is implemented for downstream process control, then productivity is improved, but measurement precision requirements increase
Solution Approach 1:
The flow cell design enables continuous sample flow through the measurement zone, allowing uninterrupted real-time molecular weight measurement. The continuous flow maintains consistent measurement conditions while providing ongoing data for downstream process control, thus maintaining both productivity and precision.
Solution Approach 2:
The system provides real-time molecular weight measurement data that can be fed back to control downstream processing parameters. This feedback mechanism ensures that measurement precision is maintained by allowing immediate detection and correction of process variations, thereby supporting both continuous operation and high measurement accuracy.
