Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional single magnetic separation unit is used, then device complexity is low, but test throughput is low
Solution Approach 1:
The magnetic separation function is divided into multiple independent magnetic separation units (first magnetic separation unit and second magnetic separation unit), each capable of performing magnetic separation cleaning independently. This segmentation allows parallel processing of multiple reaction cups, thereby increasing test throughput while maintaining manageable device complexity through modular design
Solution Approach 2:
Multiple magnetic separation units are combined within a single apparatus, sharing common components such as the reaction cup transfer mechanism and control system. This merging approach enables parallel magnetic separation operations to increase throughput while avoiding the full complexity of completely separate systems
2Speed
If traditional linear reaction plate is used, then manufacturing is simple, but test speed is low
Solution Approach 1:
The reaction plate is designed with a circular structure instead of a traditional linear arrangement. This circular configuration allows for more efficient rotational movement and better utilization of space, enabling faster transfer of reaction cups between different processing stations (sample addition, reagent addition, magnetic separation, measurement) thereby increasing test speed while remaining manufacturable
3Productivity
If single magnetic separation unit processes all cycles, then device complexity is low, but test throughput is limited
Solution Approach 1:
The magnetic separation function is divided into multiple independent magnetic separation units (first magnetic separation unit and second magnetic separation unit), each capable of performing magnetic separation cleaning independently. This segmentation allows parallel processing of multiple reaction cups, thereby increasing test throughput while maintaining manageable device complexity through modular design
Solution Approach 2:
The multiple magnetic separation units operate in parallel to continuously process multiple reaction cups simultaneously. While one unit is processing a reaction cup, another unit can simultaneously process a different reaction cup, ensuring continuous productive action without idle time and maximizing throughput

AI summary
An automatic analysis apparatus and an operating method for the automatic analysis apparatus. At least two magnetic separation units are introduced, each magnetic separation unit operating independently and being used for performing magnetic separation cleaning on a reaction solution in a reaction cup. Each magnetic separation unit may be used for any magnetic separation cleaning step in a one-step test project or a multi-step test project, thereby significantly increasing the test speed and the test throughput of the automatic analysis apparatus.
