Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sample preparation is used, then device complexity is reduced, but sample throughput is low and measurement accuracy is poor
Solution Approach 1:
The patent employs mechanical vibration through a vibrator that generates oscillations to mix the sample material with the excitation liquid in the container. This vibration mechanism automates the mixing process, significantly increasing sample throughput while maintaining measurement accuracy through consistent mechanical action.
Solution Approach 2:
The patent replaces manual mechanical mixing operations with an automated vibrator system. The vibrator substitutes for manual mixing actions, enabling automated sample preparation that increases productivity while maintaining controlled mixing conditions for accurate measurements.
2Measurement precision
If manual sample preparation is used, then device complexity is reduced, but measurement precision and reproducibility are poor
Solution Approach 1:
The vibrator generates controlled mechanical vibrations that consistently mix the sample material with the excitation liquid, ensuring uniform distribution and reproducible mixing conditions. This automated mechanical mixing eliminates the variability introduced by manual preparation, significantly improving measurement precision and reproducibility.
Solution Approach 2:
The mixing device performs self-service by automatically mixing the sample material with the excitation liquid through the vibrator. The system requires no manual intervention for the mixing process, ensuring consistent and reproducible conditions for each measurement, thereby improving measurement precision.
3Loss of time
If manual operation is used, then device complexity is reduced, but time consumption increases due to stabilization delays
Solution Approach 1:
The vibrator rapidly mixes the sample material with the excitation liquid through mechanical oscillations, significantly reducing the time required to achieve stable mixing conditions. This automated rapid mixing eliminates the prolonged stabilization delays associated with manual preparation methods.
Solution Approach 2:
The vibrator provides continuous mechanical mixing action throughout the measurement process, ensuring that the sample material remains uniformly mixed and stable. This continuous automated mixing eliminates the interruptions and delays inherent in manual operation, reducing overall time loss.
