Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the polarity of electrodes is fixed in a general sensor, then the device structure is simple, but the detection accuracy is limited and cannot sense in various directions
Solution Approach 1:
The patent applies the dynamics principle by making the electrode polarity changeable rather than fixed. The processor dynamically switches the polarity of electrodes between positive and negative states based on detection needs, enabling the sensor to detect signals from various directions and improving measurement precision without requiring multiple fixed polarity sensors
Solution Approach 2:
The patent applies parameter changes by varying the polarity parameter of the electrodes. By changing the electrical polarity parameter between positive and negative states, the sensor can adapt to different detection scenarios and sense materials positioned at different locations, thereby improving detection accuracy while maintaining a single sensor structure
2Reliability
If the polarity of electrodes is not adaptively set, then the device operation is simple, but malfunction or failure may occur
Solution Approach 1:
The patent applies feedback by implementing a control system where the processor monitors detection results and adjusts electrode polarity accordingly. This feedback mechanism ensures that the electrodes operate in optimal polarity states for different detection scenarios, preventing malfunction while maintaining automated operation that does not increase user burden
3Measurement precision
If the polarity of electrodes is adaptively set based on selected modes, then detection accuracy is improved, but the control system becomes more complex
Solution Approach 1:
The patent applies universality by designing a single electrode system that performs multiple detection functions through polarity switching. The same electrodes can detect materials from various directions and positions by changing polarity states, eliminating the need for multiple dedicated sensors for different detection scenarios and keeping the overall system compact
