Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional ECG analysis algorithms are used, then the system is simple and easy to operate, but the analysis accuracy is insufficient and cannot effectively identify arrhythmias and conduction blocks
Solution Approach 1:
The patent replaces traditional mechanical ECG analysis algorithms with artificial intelligence deep learning models. Specifically, it uses convolutional neural networks (CNN) to automatically extract ECG features and classify arrhythmias, substituting manual or rule-based analysis with intelligent algorithms that can identify complex patterns in ECG signals, thereby significantly improving diagnostic accuracy while managing system complexity through automated processing.
Solution Approach 2:
The patent transforms ECG signal parameters by converting time-domain signals into frequency-domain representations and extracting multiple physiological parameters (heart rate, RR interval, P wave duration, QRS duration, etc.). These parameter transformations enable the deep learning models to process and analyze ECG data more effectively, improving the system's ability to detect arrhythmias and conduction blocks.
2Productivity
If ECG analysis is performed manually by experts, then the diagnostic accuracy is high, but the analysis time is long and productivity is low
Solution Approach 1:
The patent implements self-service through automated ECG analysis systems that can independently process and interpret ECG data without requiring continuous expert intervention. The deep learning models automatically perform feature extraction, arrhythmia classification, and diagnostic report generation, enabling the system to serve itself in analyzing ECG signals while maintaining high diagnostic accuracy comparable to expert-level analysis.
Solution Approach 2:
The patent substitutes manual expert analysis with automated deep learning-based analysis systems. The convolutional neural networks process ECG signals rapidly, providing diagnostic results in seconds rather than minutes or hours, thereby dramatically improving productivity while maintaining or exceeding the accuracy of manual analysis through sophisticated pattern recognition capabilities.
3Adaptability or versatility
If single-lead ECG analysis is used, then the device complexity is low, but the analysis comprehensiveness is insufficient for multi-lead ECG examinations
Solution Approach 1:
The patent implements a universal ECG analysis system that can handle both single-lead and multi-lead ECG examinations. The deep learning model is designed to process ECG data from any lead configuration, automatically adapting to different input types. This multi-functional capability allows the same system to effectively analyze various ECG formats without requiring separate processing pipelines, thereby improving versatility while managing complexity through unified architecture.
Solution Approach 2:
The patent segments the ECG analysis process into independent modular components: data preprocessing, feature extraction, arrhythmia classification, and report generation. Each module can process specific aspects of single-lead or multi-lead data independently, allowing the system to handle different lead configurations by activating appropriate segments. This modular segmentation enables flexible adaptation to various ECG types without overwhelming system complexity.
4Reliability
If noise is treated as a special heart rhythm event, then the classification is simplified, but the noise influence on subsequent analysis is not removed
Solution Approach 1:
The patent extracts and separates noise components from ECG signals before main analysis. The system identifies and removes various types of interference (muscle artifacts, baseline wander, power line noise) as distinct elements, preventing them from contaminating the arrhythmia classification process. By taking out noise separately and handling it through dedicated preprocessing steps, the system improves analysis reliability without requiring complex integrated noise-management mechanisms.
