Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual color comparison is used, then operation simplicity is maintained, but measurement precision deteriorates due to interpretation errors
Solution Approach 1:
The patent replaces the manual visual comparison system with an automated image recognition and colorimetric analysis system. The mobile communication device captures images of the test strip and colorimetric plate, and the processing unit automatically performs coordinate correction and color level comparison, eliminating human interpretation errors while maintaining ease of operation.
Solution Approach 2:
The patent introduces an intermediary computational system that mediates between the visual test strip and the final result. The processing unit acts as an intermediary that captures images, performs coordinate corrections based on positioning markers, and compares color levels objectively, thereby improving measurement precision without complicating the user workflow.
2Measurement precision
If image recognition is applied, then measurement precision is improved, but device complexity increases due to complicated positioning and calibration procedures
Solution Approach 1:
The patent applies preliminary action by pre-positioning markers on the test strip and colorimetric plate before the actual measurement. These markers enable the processing unit to automatically perform coordinate corrections without requiring complex real-time calibration procedures during detection, thereby maintaining high precision while reducing operational complexity.
Solution Approach 2:
The patent uses positioning markers that create reference copies or landmarks in the captured image. These markers serve as copying references that allow the system to automatically determine coordinate transformations and align the test strip image with the colorimetric plate, simplifying the calibration process while maintaining detection accuracy.
3Measurement precision
If specific devices are used to fix test strip or image capture device, then measurement precision is improved, but loss of substance increases due to additional devices and costs
Solution Approach 1:
The patent makes the mobile communication device multi-functional by using it for both image capture and processing. The same device that users already possess for communication is also used for medical testing, eliminating the need for separate specialized imaging devices and reducing overall system costs while maintaining sufficient image quality for accurate detection.
Solution Approach 2:
The patent enables the mobile communication device to perform its own image processing and analysis functions. The processing unit within the same device that captured the image performs coordinate correction, colorimetric calibration, and result determination, eliminating the need for additional external processing equipment and reducing overall system complexity and cost.
