Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If commercially available colloidal particles are used for instrument calibration, then measurement accuracy can be maintained, but sample preparation procedures are required due to high concentration
Solution Approach 1:
The patent introduces a dilution device as an intermediary component between the high-concentration colloidal particle source and the particle instrument. This device automatically performs the sample preparation by diluting the concentrated colloidal particles to appropriate concentrations for instrument testing, eliminating the need for manual preparation procedures while maintaining measurement accuracy.
Solution Approach 2:
The system enables self-service calibration by automatically handling the sample preparation process. The dilution device is integrated into the calibration system, allowing it to automatically dilute and deliver colloidal particles to the instrument without requiring external manual intervention, thus maintaining accuracy while simplifying operation.
2Reliability
If standardized methods for injecting colloidal particles are implemented, then calibration reliability improves, but existing systems are expensive and difficult to use
Solution Approach 1:
The patent segments the injection system into distinct functional modules: a colloidal particle source, a dilution device, an injection device, and a particle instrument. Each module performs a specific function independently, making the overall system easier to operate and maintain while ensuring reliable calibration through standardized integration of these components.
Solution Approach 2:
The system standardizes calibration by controlling and changing key parameters such as colloidal particle concentration, injection flow rate, and mixing ratios. By establishing standardized parameter ranges and automated control mechanisms, the system achieves reliable calibration results while simplifying operation through automated parameter management.
3Quantity of substance
If colloidal particle solutions are highly concentrated, then particle availability is sufficient, but sample preparation procedures are normally required
Solution Approach 1:
The dilution device performs preliminary dilution of the highly concentrated colloidal particle solution before the particles are injected into the instrument. This preliminary action reduces the concentration to appropriate levels for accurate measurement, eliminating the need for separate manual sample preparation steps while maintaining sufficient particle availability for calibration.
