Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a generic machine learning model is used for disease prediction, then the system is simple to implement, but the predictive performance varies across different scan protocols
Solution Approach 1:
The patent implements a dynamic protocol adaptation circuit that automatically adjusts the disease prediction model's parameters based on the detected scan protocol. This dynamic adjustment allows the system to maintain high predictive performance across different protocols without requiring multiple static models, thus resolving the contradiction between implementation simplicity and performance consistency.
2Reliability
If the disease prediction model is adapted to each specific protocol, then the predictive performance improves, but the system complexity increases
Solution Approach 1:
The patent segments the protocol adaptation function into a separate detectable feature generator circuit that identifies scan protocol characteristics. This segmentation allows the main disease prediction model to remain relatively simple while the adaptation handling is delegated to a specialized subsystem, thus reducing overall system complexity while maintaining performance.
Solution Approach 2:
The patent introduces a protocol detection and adaptation intermediary layer between the image input and the disease prediction model. This intermediary automatically detects scan protocol features and adjusts model parameters accordingly, serving as a mediator that enables protocol-specific optimization without requiring direct complex integration between the model and multiple protocol configurations.
3Measurement precision
If scan protocol information is collected and analyzed, then the disease risk assessment accuracy improves, but the processing time increases
Solution Approach 1:
The patent performs scan protocol detection and feature extraction as a preliminary action before the main disease prediction process. By identifying the scan protocol early in the workflow, the system can pre-configure appropriate model parameters and avoid time-consuming adjustments during the prediction phase, thus maintaining accuracy while minimizing processing time.
