Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If batch processing is used for automatic pre-processing, then automation is achieved, but selective concentration on individual samples cannot be performed
Solution Approach 1:
The batch processing system is segmented into individual sample handling units, where each sample can be independently directed to either the evaporative concentration unit or bypass it. This segmentation allows selective concentration while maintaining overall automation through centralized control.
2Measurement precision
If evaporative concentration is performed on all samples, then high-sensitivity detection is enabled, but unnecessary processing time is added to samples that do not require concentration
Solution Approach 1:
The system dynamically adjusts the processing path for each sample based on real-time control decisions. Samples requiring high-sensitivity detection are dynamically routed through the evaporative concentration unit, while others bypass it, optimizing processing time while maintaining detection sensitivity when needed.
3Adaptability or versatility
If a mechanism for selective concentration is added, then individual sample control is enabled, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it manages the overall automated pre-processing workflow, determines which samples require concentration based on analysis requirements, and directs samples to appropriate processing paths. This multi-functionality reduces the need for separate dedicated components for each control function.

AI summary
The automatic analysis device includes an evaporative concentration unit configured to perform a concentration process of evaporating an extract solution obtained by extracting a component to be analyzed in a sample to concentrate the component to be analyzed; an analysis unit configured to analyze the component to be analyzed of the sample; and a control unit configured to control operations of the analysis unit and the evaporative concentration unit. The control unit determines whether to perform an evaporative concentration process on a component to be analyzed in the sample, and controls the evaporative concentration unit to concentrate a component to be analyzed in a sample which is determined to be subjected to an evaporative concentration process. The sample to be subjected to the evaporative concentration process is stored, and the control unit selects whether to perform the evaporative concentration on each sample or not based on stored content.
