Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current calibration systems are used, then the mass spectrometer can operate, but it cannot simultaneously recognize and quantify isotopic analogs, leading to inaccurate and delayed results
Solution Approach 1:
The patent changes the calibration approach by introducing isotopic analogs with known quantities into the sample matrix. This parameter change allows the system to simultaneously recognize and quantify multiple isotopic forms, resolving the contradiction between measurement precision and adaptability to different analyte forms.
Solution Approach 2:
Isotopic analogs serve as intermediaries between the mass spectrometer and the target analyte. These analogs have known quantities and similar mass-to-charge ratios, enabling the system to accurately quantify the analyte while maintaining the ability to handle various isotopic forms simultaneously.
2Productivity
If data analysis is performed using current methods, then results can be obtained, but the process is time consuming and inefficient
Solution Approach 1:
The patent performs preliminary action by spiking the sample matrix with isotopic analogs of known quantities before analysis. This pre-preparation enables real-time quantification during the mass spectrometric run, eliminating time-consuming post-processing calculations and providing actionable data immediately.
3Reliability
If conventional calibration systems are used, then the mass spectrometer can process samples, but instrumental variability leads to inefficient and inaccurate data
Solution Approach 1:
The calibration system performs self-service by using isotopic analogs with known quantities that are processed through the same mass spectrometer and analysis pipeline as the target analyte. This self-calibration approach automatically compensates for instrumental variability without requiring complex external calibration procedures, improving reliability while maintaining simplicity.
