Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional marking compounds are used for detecting origin of hydrocarbon compositions, then the marking can be detected by laboratory analysis, but the analysis requires sophisticated equipment and cannot be performed quickly on site
Solution Approach 1:
The patent replaces conventional laboratory analytical methods with EPR (Electron Paramagnetic Resonance) spectroscopy, which is a physical detection method based on magnetic resonance. This substitution enables detection without complex chemical analysis equipment, allowing portable devices to be used on-site while maintaining detection precision through the specific magnetic resonance signal of the radical compound marker.
Solution Approach 2:
The invention changes the detection parameter from general chemical analysis to specific magnetic resonance signal detection. By using a radical compound marker with unpaired electrons, the system exploits the unique EPR signal characteristics (g-factor, hyperfine coupling) to identify the marker, enabling selective and sensitive detection with simplified equipment compared to broad-spectrum laboratory analysis.
2Loss of information
If conventional marking compounds are used for tracing manufacturing processes, then the origin can be determined by laboratory analysis, but the process cannot be traced quickly and the quality control is time-consuming
Solution Approach 1:
The radical compound marker is incorporated into the hydrocarbon composition during the manufacturing process itself, serving as a pre-installed traceable identifier. This preliminary action embeds the tracking information directly in the product, eliminating the need for subsequent complex analysis to determine origin or batch information, thus enabling rapid quality control and traceability verification.
Solution Approach 2:
The patent replaces time-consuming laboratory chromatography or spectroscopy methods with rapid EPR detection. The EPR technique provides quick identification of the radical compound marker, enabling fast traceability verification and quality control decisions to be made on-site without lengthy analytical procedures.
3Measurement precision
If marking compounds requiring laboratory analysis are used, then accurate detection is possible, but portable on-site detection cannot be achieved
Solution Approach 1:
The invention substitutes complex laboratory analytical systems with a portable EPR spectrometer system. The EPR detection method, based on magnetic resonance of unpaired electrons in the radical compound, can be implemented in a compact, portable device that maintains laboratory-level detection accuracy while enabling field operations. The specific magnetic resonance signal provides unambiguous identification of the marker.
Solution Approach 2:
The radical compound marker serves multiple functions: it provides a detectable signal for origin identification, enables batch tracing, and works with portable EPR devices for on-site detection. This multi-functional marker system replaces the need for multiple different analytical methods and equipment, unifying detection capabilities across laboratory and field settings.
