Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional mass spectrometry technologies are used, then device complexity is reduced, but measurement precision and mass storage capability deteriorate
Solution Approach 1:
The patent combines a quadrupole ion trap with an electrostatic ion bottle to create a hybrid mass spectrometer system. The ion trap provides ion confinement and selection capabilities, while the ion bottle provides high-mass storage and time-of-flight analysis capabilities. This merging of two different ion manipulation technologies enables both high mass measurement precision and extended mass storage capability that neither device could achieve alone.
Solution Approach 2:
The mass spectrometer is divided into distinct functional modules: an ion source, a quadrupole ion trap for ion confinement and selection, an electrostatic ion bottle for high-mass storage, and detection systems. Each module performs a specific function, allowing the system to achieve high measurement precision through specialized components while managing overall device complexity through modular architecture.
2Quantity of substance
If high mass storage capability is implemented, then measurement precision improves, but device complexity increases
Solution Approach 1:
The electrostatic ion bottle serves as an intermediary component between the ion source and the detector. It provides a controlled environment for storing and manipulating high-mass ions before analysis, enabling extended mass storage capability while simplifying the overall system architecture by providing a dedicated storage zone that mediates between ion generation and detection processes.
3Measurement precision
If ultrahigh resolution mass measurements are performed, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system employs dynamic voltage control of the electrostatic mirrors in the ion bottle, allowing the electric field configuration to be adjusted in real-time. This dynamic control enables the system to optimize ion storage and analysis conditions for different mass ranges and resolution requirements, achieving ultrahigh mass resolving power while managing device complexity through software-controlled parameter adjustment rather than hardware reconfiguration.
