Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed electric field region is used in the ion analysis device, then the device structure is simple, but the device can only analyze a limited range of ion concentrations
Solution Approach 1:
The patent applies the dynamics principle by making the electric field generation region adjustable rather than fixed. The deflection electrode's active region can be dynamically changed in the width direction, allowing the device to adapt to different ion concentration ranges by adjusting which portions of the electrode generate the electric field, thus resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent implements parameter changes by varying the width of the electric field generation region in the width direction. By changing this geometric parameter of the deflection electrode's active area, the device can optimize its performance for different ion concentration levels, enabling analysis across a wider range without fundamentally redesigning the system.
2Quantity of substance
If the electric field region width is increased to capture more ions, then more ions can be detected, but the measurement precision decreases for high concentration samples
Solution Approach 1:
The patent uses dynamics to allow the electric field region width to be adjusted based on the ion concentration being measured. For high concentration samples, the width is reduced to improve precision; for low concentration samples, the width is increased to capture more ions. This dynamic adjustment resolves the contradiction between detecting sufficient ion quantity and maintaining measurement precision.
Solution Approach 2:
The patent changes the width parameter of the electric field generation region to optimize the balance between ion detection quantity and measurement precision. By adjusting this parameter according to sample concentration, the system achieves both sufficient ion capture and accurate measurement across different concentration levels.
3Measurement precision
If the electric field region width is decreased to improve measurement precision, then precision increases for high concentration samples, but fewer ions are captured reducing detection efficiency
Solution Approach 1:
The patent applies dynamics by making the electric field region width adjustable rather than fixed. The system can dynamically optimize the width parameter to achieve both high measurement precision and adequate ion detection efficiency by matching the electric field region to the appropriate ion concentration level being measured.
Solution Approach 2:
The patent utilizes parameter changes by varying the width of the electric field generation region. This parameter adjustment allows the system to optimize the trade-off between measurement precision and detection efficiency, ensuring sufficient ions are captured while maintaining accurate measurements across different concentration ranges.
