Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual configuration is used to optimize analysis of multiple analytes, then analysis quality can be improved, but time consumption and error probability increase significantly
Solution Approach 1:
The system enables self-service automation where the mass spectrometer automatically configures its own operation parameters based on database information about the analytes to be analyzed. The controller retrieves analyte information from the database and automatically determines optimal duty cycles and command signals without requiring manual user configuration, thus eliminating time-consuming manual setup while maintaining optimal analysis quality
Solution Approach 2:
The system performs preliminary action by pre-storing comprehensive analyte information and optimal analysis parameters in a database before actual analysis. When analysis is needed, the controller simply retrieves pre-prepared duty cycle and command signal configurations from the database based on the analyte identifier, eliminating the need for time-consuming real-time manual configuration while ensuring optimal analysis conditions are applied
2Productivity
If manual configuration commands are provided for optimal MRM analysis, then analysis efficiency can be improved, but operation complexity and error probability increase
Solution Approach 1:
The mass spectrometer system performs self-service by automatically determining and configuring optimal MRM duty cycles and command signals based on analyte information retrieved from the database. The controller handles the entire configuration process autonomously without requiring users to provide complex manual commands, thus maintaining high analysis efficiency while dramatically simplifying user operation to merely inputting the analyte identifier
Solution Approach 2:
The database serves as an intermediary between the user and the mass spectrometer configuration. Instead of requiring users to directly provide complex configuration commands, they simply input an analyte identifier, and the database automatically translates this into the appropriate duty cycle and command signal configurations, thereby simplifying operation while maintaining analysis efficiency
3Adaptability or versatility
If the mass spectrometer is configured for varying m/z ratios over time, then detection capability is improved, but system complexity increases
Solution Approach 1:
The system implements dynamic configuration where the mass spectrometer's operating parameters (duty cycles and command signals) are automatically adjusted in real-time based on the specific analyte being analyzed and its expected elution time. The controller dynamically retrieves and applies appropriate configurations from the database, enabling the system to adapt to varying m/z ratios and analysis requirements without requiring complex manual reconfiguration for each analyte
Solution Approach 2:
The database serves as a universal repository containing pre-configured optimal parameters for multiple different analytes with varying m/z ratios. The system can handle diverse detection requirements through a single unified configuration approach where the controller retrieves appropriate parameters from the database based on the analyte identifier, eliminating the need for separate complex configuration procedures for each different analyte type
