Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional detectors are used to analyze non-conductive samples, then the analysis can be performed, but the measurement accuracy is insufficient
Solution Approach 1:
The patent applies parameter changes by varying the electromagnetic field strength to ionize different components of the sample at different thresholds. This allows the detector to distinguish between various substances based on their characteristic ionization energies, thereby improving measurement precision for composition determination while maintaining reliable detection through systematic parameter variation.
Solution Approach 2:
The patent replaces traditional mechanical or optical detection methods with electromagnetic field-based ionization and conductivity measurement. By using electromagnetic fields to ionize components and measure resulting conductivity changes, the system achieves higher accuracy in composition analysis of non-conductive samples compared to conventional mechanical or optical detectors.
2Productivity
If measurement speed is increased, then productivity improves, but measurement precision may deteriorate
Solution Approach 1:
The patent implements continuous measurement by continuously increasing the electromagnetic field strength and continuously monitoring conductivity changes. This continuous action allows the system to rapidly identify ionization thresholds and determine composition without interruption, achieving both high productivity through rapid measurement and high precision through continuous data collection and analysis.
3Volume of moving object
If the detector structure is made compact, then device size is reduced, but robustness may deteriorate
Solution Approach 1:
The patent merges the electromagnetic field generation components and detection components into a single compact measuring cell structure. The first and second poles are positioned close together to create the necessary electromagnetic field within a small volume, while the detection electronics are integrated into the same compact structure, achieving miniaturization without sacrificing robustness through careful integration of all necessary components.
