Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrical energy is supplied to the electrode catheter during ablation treatment, then the arrhythmia site can be cauterized, but it becomes difficult to simultaneously identify the arrhythmia-causing site with diagnostic accuracy
Solution Approach 1:
The patent segments the electrode catheter into multiple electrodes (first electrode group and second electrode group) positioned at different locations. Each electrode measures electrocardiographic waveforms independently, allowing the system to identify the earliest abnormal waveform and its location even during simultaneous ablation treatment, thus maintaining diagnostic accuracy while enabling treatment.
Solution Approach 2:
The system performs preliminary measurement of electrocardiographic waveforms by multiple electrodes before and during the ablation process. By continuously monitoring and identifying the earliest abnormal waveform in advance, the system provides diagnostic information that guides the ablation treatment, ensuring accurate identification of the arrhythmia site even as treatment progresses.
2Measurement precision
If multiple electrocardiographic waveforms are measured simultaneously by multiple electrodes, then the arrhythmia site can be identified more accurately, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential information needed for diagnosis - specifically, the earliest abnormal waveform and its timing - from the multiple electrocardiographic waveforms measured by different electrodes. By focusing on this key diagnostic parameter rather than processing all waveform data equally, the system maintains high identification accuracy while reducing computational and device complexity.
Solution Approach 2:
The system applies local quality by assigning different functional roles to different electrode groups. The first electrode group measures waveforms for detecting abnormality timing, while the second electrode group provides reference measurements. This functional differentiation allows accurate arrhythmia site identification through coordinated measurement rather than requiring all electrodes to perform identical complex functions.
3Loss of time
If real-time detection of earliest abnormal waveform is implemented, then timely diagnostic information is provided to doctors, but the processing requirements and system complexity increase
Solution Approach 1:
The system performs preliminary comparison of waveforms from multiple electrodes to identify which electrode detected the abnormal waveform first. By continuously monitoring and pre-identifying the earliest abnormal waveform in real-time, the system provides immediate diagnostic information to doctors without requiring complex post-processing analysis, thus minimizing time loss while keeping processing requirements manageable.
