Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single biochemical item detection disc is used, then the detection function is simple and easy to operate, but it cannot meet the detection needs of multiple biochemical freeze-dried reagents with different dilution ratios
Solution Approach 1:
The detection disc is divided into multiple independent detection units (first detection unit and second detection unit), each capable of performing biochemical detection with different dilution ratios. Each unit includes separate dosing tanks, mixing tanks, and detection holes, allowing simultaneous multi-index detection while maintaining operational simplicity through modular design
Solution Approach 2:
The detection disc is designed to perform multiple biochemical detection functions simultaneously by integrating multiple detection units that can handle different dilution ratios (1:1, 1:2, 1:4, etc.). This multi-functional design enables a single disc to meet the detection needs of various biochemical freeze-dried reagents without requiring separate instruments
2Reliability
If separate blood cell tests and biochemical tests are performed on different instruments, then each test can be optimized, but the operation becomes complicated and requires two blood samples
Solution Approach 1:
The detection disc merges blood cell detection and biochemical detection functions into a single integrated platform. By combining multiple detection units with different dilution ratios on one disc, the system enables simultaneous performance of both blood cell tests and biochemical tests using a single blood sample, thereby simplifying operation while maintaining test accuracy
3Measurement precision
If different kinds of freeze-dried reagents require samples with different dilution ratios, then optimal detection effect is achieved, but a single sample cannot meet all detection needs
Solution Approach 1:
The detection disc incorporates dynamic dilution capabilities through multiple dosing tanks and mixing tanks that can be configured to provide different dilution ratios (1:1, 1:2, 1:4, etc.) for the same blood sample. This dynamic adjustment allows the system to adapt to the specific dilution requirements of different biochemical freeze-dried reagents while maintaining optimal detection precision for each
