Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If current blood typing methods are used, then blood compatibility can be determined, but the process is time-consuming and not suitable for emergency situations
Solution Approach 1:
The patent replaces manual visual inspection of blood agglutination with an automated image processing system. A camera captures images of the blood sample reactions, and computer algorithms automatically analyze the images to detect agglutination patterns, eliminating the need for manual observation and significantly reducing determination time
Solution Approach 2:
The system enables self-service blood typing by allowing the device to automatically perform image capture, processing, and result interpretation without requiring trained laboratory personnel. The automated analysis algorithm independently evaluates the blood sample reactions and provides blood type determination
2Reliability
If manual reading of blood agglutination is performed, then blood type can be determined, but human error and contamination risk increase
Solution Approach 1:
The patent replaces the human reading process with an automated image processing system that captures and analyzes blood agglutination patterns. The camera and computer algorithm objectively detect and interpret the reactions, eliminating subjective human error, fatigue-related mistakes, and contamination risks associated with manual handling
Solution Approach 2:
The system creates a digital copy of the blood reaction through image capture, allowing multiple analyses of the same sample without physical contact or contamination. The image can be processed repeatedly and archived for verification, ensuring consistent and reliable results
3Productivity
If automated image processing is implemented, then speed and accuracy improve, but device complexity increases
Solution Approach 1:
The patent employs a camera, which is a universal imaging device, instead of specialized optical equipment. The image processing algorithms can analyze various blood reactions and potentially other diagnostic patterns, making the system multi-functional while keeping hardware requirements simple and accessible
Solution Approach 2:
The system uses standard, readily available components like digital cameras and conventional computers rather than expensive specialized medical equipment. This approach reduces device complexity and cost while maintaining high productivity through automated processing capabilities
