Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple ECG tests are performed according to guideline recommendations, then the evaluation accuracy for ACS is improved, but the workload on medical staff increases and the time required for diagnosis increases
Solution Approach 1:
The ECG evaluation system performs self-diagnosis by automatically analyzing multiple ECG waveforms and generating diagnostic reports without requiring skilled medical staff to manually evaluate each ECG. The system autonomously compares waveforms, detects ST-level changes, and produces ACS evaluation reports, thereby maintaining high evaluation accuracy while eliminating the time and effort burden on medical professionals.
Solution Approach 2:
The patent replaces the mechanical process of manual ECG evaluation by medical staff with an automated computer-based system. The computer automatically processes multiple ECG recordings, compares waveform characteristics, detects pathological changes, and generates diagnostic conclusions, substituting human expertise with automated algorithms that maintain diagnostic accuracy while improving efficiency.
2Reliability
If multiple ECG tests are performed to evaluate ACS possibility, then the diagnostic reliability is improved, but the time required for diagnosis increases
Solution Approach 1:
The system continuously monitors and processes ECG waveforms in real-time, automatically comparing each new ECG recording with previous ones to detect temporal changes. This continuous automated analysis ensures that diagnostic reliability is maintained through multiple evaluations while the time required is minimized, as the system operates without interruption and immediately processes new data upon acquisition.
Solution Approach 2:
The system performs preliminary automated analysis of ECG waveforms immediately upon acquisition, before final diagnostic conclusions are needed. By pre-processing and comparing waveforms in advance, the system prepares diagnostic information ahead of time, enabling rapid final diagnosis while maintaining the reliability that comes from comprehensive multi-timepoint evaluation.
3Measurement precision
If automated analysis processing is performed multiple times on continuous ECG, then the detection accuracy for ACS is improved, but the processing time and computational load increase
Solution Approach 1:
The patent segments the ECG analysis into distinct functional components: waveform extraction, ST-level measurement, comparison with reference values, and diagnostic conclusion generation. By dividing the complex analysis process into separate modular steps, the system can efficiently process multiple ECG recordings through automated analysis while maintaining high detection accuracy and reducing overall processing time through optimized sequential execution.
