Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to predict hematoma expansion, then the process is simple, but the prediction accuracy is low
Solution Approach 1:
The patent replaces traditional mechanical/visual assessment methods with an automated deep learning system that uses convolutional neural networks to analyze CT images. This substitution enables high-accuracy prediction of hematoma expansion by automatically extracting imaging features and patterns that are imperceptible to human observers, thereby resolving the contradiction between prediction accuracy and system complexity.
Solution Approach 2:
The patent introduces a deep learning algorithm as an intermediary between the CT images and the prediction outcome. This intermediary automatically processes the imaging data, extracts relevant features, and generates predictions, eliminating the need for complex manual assessment while achieving high accuracy through automated feature extraction and pattern recognition.
2Measurement precision
If deep learning analysis is implemented, then prediction accuracy improves, but processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-training the deep learning model on large datasets and pre-processing the CT images into standardized formats before actual prediction. This preparation work is done in advance, allowing the model to quickly process new cases without sacrificing accuracy, thereby reducing the time loss during critical clinical decision-making.
Solution Approach 2:
The patent optimizes processing time by adjusting parameters such as image resolution, network depth, and batch size to find the optimal balance between accuracy and speed. By changing these parameters, the system achieves high prediction accuracy while maintaining processing speeds suitable for clinical workflows.
3Measurement precision
If manual assessment methods are used, then the system is easy to operate, but the precision of identifying patients is low
Solution Approach 1:
The patent implements self-service by enabling the deep learning system to automatically perform the entire assessment process without requiring manual intervention. The system autonomously analyzes CT images, identifies patients at risk of hematoma expansion, and generates predictions, thereby achieving high precision while maintaining ease of operation through automation.
Solution Approach 2:
The patent replaces manual visual assessment with automated deep learning analysis, substituting human operators with an intelligent system that provides both high precision and operational simplicity. This substitution eliminates the trade-off by achieving superior accuracy through automated feature extraction while reducing operational complexity through workflow automation.
