Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sample preparation methods are used for determining characteristics of liquid media, then comprehensive quality control can be achieved, but the process requires extensive time and complex procedures
Solution Approach 1:
The patent combines the sample preparation function and measurement function into a single integrated device. The container serves both as the sample holder and the measurement chamber, eliminating the need for separate sample preparation steps. Sensors are directly positioned within the container to measure physical, chemical, and biological characteristics in situ, thereby reducing preparation time while maintaining measurement accuracy.
Solution Approach 2:
The system enables self-measurement by placing sensors directly in contact with the liquid medium within the original container. The container itself becomes part of the measurement system, allowing direct characterization without requiring external sample preparation equipment or procedures, thus significantly reducing time loss.
2Measurement precision
If traditional measurement methods are used, then sample characteristics can be determined, but packaging influences are not considered leading to incomplete results
Solution Approach 1:
The measurement system is integrated with the packaging container, allowing simultaneous measurement of liquid medium characteristics and packaging properties. The device measures not only the liquid parameters but also captures information about the container material and its interaction with the liquid, providing complete data for accurate characteristic determination.
3Productivity
If direct measurement in the container is implemented, then processing time is reduced, but measurement reliability may be affected by container interference
Solution Approach 1:
The sensors are positioned at specific locations within the container where interference from the container walls is minimized. The measurement system is designed to detect signals from the liquid medium while filtering out or compensating for container-related interference, ensuring reliable measurements are taken at optimal points within the container volume.
