Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single AI classification model is used for medical image analysis, then the system complexity is low, but the accuracy rate and reliability of disease classification are insufficient
Solution Approach 1:
The system segments the classification task into multiple specialized AI models, each focusing on specific disease categories or image features. This segmentation allows each model to specialize in particular patterns, improving overall accuracy while maintaining manageable complexity through modular architecture
Solution Approach 2:
Multiple AI models are merged into an integrated ensemble system that combines their predictions. The merging process integrates diverse model outputs through weighted voting or averaging, achieving higher reliability by leveraging the strengths of individual models while compensating for their individual weaknesses
2Measurement precision
If a single AI model is used for lesion detection, then the model is simple to implement, but it cannot effectively recognize small lesions and the misinterpretation rate is high
Solution Approach 1:
The detection task is segmented into multiple specialized models, each trained to detect specific types of lesions or features at different scales. This segmentation enables precise detection of small lesions by dedicating specific models to detect fine-grained features that general models might miss
Solution Approach 2:
Feature extraction modules serve as intermediaries between the input images and classification models. These intermediaries enhance lesion features through specialized processing, making small lesions more detectable by subsequent classification models without requiring direct complex interactions between all components
3Reliability
If multiple complementary AI models are used for image classification and object detection, then the accuracy and reliability of disease classification are improved, but the system complexity increases
Solution Approach 1:

4Measurement precision
If feature integration and transformation is performed on multiple detection results, then the recognition of small lesions is enhanced, but the computational complexity increases
Solution Approach 1:
The system extracts only the most relevant features from multiple detection results for integration, rather than processing all possible features. This selective extraction reduces computational overhead while maintaining the ability to recognize small lesions by focusing on discriminative features that matter most for detection accuracy
