Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual examination under microscope is used for malaria diagnosis, then diagnostic accuracy can be maintained through expert judgment, but time consumption and human error increase significantly
Solution Approach 1:
The patent replaces the mechanical manual examination process with an automated optical analysis system that uses light scattering measurements and classification algorithms to diagnose malaria, eliminating the need for manual microscope examination while maintaining diagnostic accuracy
Solution Approach 2:
The system enables self-service diagnosis by automatically analyzing blood samples through optical measurements and classification algorithms, allowing the system to perform diagnostic functions independently without requiring expert manual intervention
2Reliability
If manual counting of ring-shaped red blood cells is performed, then diagnostic reliability can be achieved through expert assessment, but subjectivity and inter-laboratory variability increase
Solution Approach 1:
The patent transforms the diagnostic approach by changing from subjective visual assessment parameters to objective optical measurement parameters (light scattering intensity, angular distribution), enabling standardized and reproducible diagnoses across different laboratories
Solution Approach 2:
The system replaces subjective human assessment with automated optical measurement and classification algorithms, eliminating inter-laboratory variability and subjectivity while maintaining diagnostic reliability
3Extent of automation
If optical analysis methods are used for dispersion examination, then automation can be achieved, but information content and diagnostic precision are limited
Solution Approach 1:
The patent enhances the information content by measuring light scattering in multiple angular dimensions and combining multiple optical features (intensity, angular distribution, spectral characteristics) to create a comprehensive classification index that provides rich diagnostic information
Solution Approach 2:
The optical analysis system is designed to perform multiple diagnostic functions by analyzing various optical features of blood cells, enabling it to differentiate between malaria-infected cells and normal cells through multi-parameter optical characterization
4Reliability
If standardized classification criteria are implemented for malaria diagnosis, then diagnostic consistency can be improved, but flexibility in handling atypical cases may be reduced
Solution Approach 1:
The classification system is designed to be dynamic and adaptive, using statistical classification algorithms that can adjust to different case types and provide probabilistic diagnoses, allowing flexibility in handling atypical cases while maintaining standardized criteria for common presentations
