Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate samples are prepared for different detection results, then detailed information about the sample can be acquired, but the work becomes complicated
Solution Approach 1:
The single sample chamber is designed to perform multiple detection functions by adjusting the fluidal state of the sample. The same physical sample can be analyzed in different fluidal states (strong, weak, intermediate) to obtain various detection results, eliminating the need for multiple separate sample preparations while maintaining comprehensive analytical capability
Solution Approach 2:
The system dynamically adjusts the fluidal state of the sample using an adjustment unit that can change flow rate, circulation, or agitation. This dynamic control allows the sample to transition between different fluidal states during measurement, enabling multiple detection modes without requiring separate static sample preparations
2Productivity
If the sample is held stationary on the reflection surface, then the apparatus structure is simple, but detailed information about different sample states cannot be acquired
Solution Approach 1:
The adjustment unit introduces dynamic fluidal state control into the sample holding system. By adjusting flow rate, circulation, or agitation, the sample can transition between stationary and flowing states, enabling comprehensive information acquisition about different sample states while maintaining a relatively simple apparatus structure
Solution Approach 2:
The system changes the fluidal state parameter of the sample to obtain different detection results. By controlling parameters such as flow rate, circulation speed, or agitation intensity, the apparatus can acquire information about the sample in various states without significantly complicating the overall structure

AI summary
An ATR apparatus includes a prism having a reflection surface, a holding unit holding a sample including a suspension on the reflection surface, and an adjustment unit adjusting a fluidal state of the sample held on the reflection surface. The adjustment unit adjusts the fluidal state of the sample to a first fluidal state in order to acquire a first detection result relating to the sample in the first fluidal state and adjusts the fluidal state of the sample to a second fluidal state in order to acquire a second detection result relating to the sample in the second fluidal state.
