Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional detection methods are used, then direct contact with materials can be established, but detection accuracy deteriorates due to interference and environmental noise
Solution Approach 1:
The patent introduces an intermediary detection mechanism that does not require direct contact between the detector and the material. Instead, it uses electromagnetic field interactions and resonance frequency analysis as intermediaries to indirectly detect material properties, thereby avoiding direct contact while maintaining detection accuracy and reducing susceptibility to environmental noise and interference
2Productivity
If traditional detection methods are used, then materials can be detected, but detection time increases making the process time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-calibrating resonance frequency parameters and detection thresholds before actual material detection. The system stores reference data for various materials and their characteristic resonance frequencies, allowing rapid comparison during detection without requiring time-consuming real-time analysis, thus significantly reducing detection time while maintaining accuracy
3Quantity of substance
If traditional detection methods are used, then materials can be identified, but ability to detect small quantities deteriorates
Solution Approach 1:
The patent utilizes resonance frequency analysis, which is based on the principle of mechanical vibration and oscillation. By transmitting electromagnetic signals at specific frequencies and analyzing the resonance response of the material, the system can detect even trace amounts of substances through their characteristic vibrational responses, significantly enhancing detection sensitivity for small quantities compared to traditional detection methods
4Measurement precision
If traditional detection methods are used, then materials can be detected, but identification accuracy deteriorates leading to ambiguous results
Solution Approach 1:
The patent employs parameter changes by analyzing multiple resonance frequency parameters simultaneously rather than relying on a single detection signal. The system varies detection parameters such as frequency, amplitude, and phase characteristics to create a multi-dimensional signature for each material, making identification more accurate and reducing ambiguity by providing richer informational content for differentiation between similar materials
