Engineering Contradiction Analysis
1Reliability
If fixed time allocation for each step is used to guarantee measurement sensitivity, then measurement reliability is improved, but measurement time is extended unnecessarily
Solution Approach 1:
The patent applies dynamics by transitioning from fixed, uniform time allocation for each test step to dynamic time adjustment based on actual reaction progress. The system monitors electromagnetic wave signals in real-time and automatically adjusts the duration of each step according to the detected reaction state, allowing the measurement process to adapt its timing to the specific kinetics of each test substance while maintaining sufficient sensitivity.
Solution Approach 2:
The patent implements feedback by continuously detecting electromagnetic wave signals during the test process and using this information to control the timing of subsequent steps. The system measures the state of the reaction mixture at each step, compares it against expected progression patterns, and adjusts the timing of wash steps, incubation periods, and signal detection accordingly, creating a closed-loop control system that optimizes both speed and sensitivity.
2Stability of the object's composition
If uniform time setting for all test items is applied, then measurement consistency is maintained, but test efficiency is reduced due to unnecessary extended duration
Solution Approach 1:
The patent applies parameter changes by dynamically modifying the time parameter for each test step based on the detected reaction progress. Instead of using a single uniform time setting for all test items, the system adjusts timing parameters in real-time according to the specific kinetic characteristics of each antigen-antibody reaction, allowing faster reactions to proceed more quickly while ensuring sufficient time for slower reactions, thereby maintaining consistency across different test items while improving overall efficiency.
3Device complexity
If fixed step timing is used to simplify control, then device complexity is reduced, but measurement optimization is lost
Solution Approach 1:
The patent replaces the mechanical/time-based control system with an electromagnetic field-based detection and control system. Instead of relying on pre-programmed fixed timing sequences, the system uses electromagnetic wave detection to monitor reaction progress and automatically adjusts timing based on real-time measurements. This substitution of mechanical timing control with electromagnetic sensing and feedback control enables optimization without significantly increasing operational complexity.
