Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional 12-channel ECG is used, then the equipment is simple and easy to operate, but the spatial resolution is inadequate and provides limited information
Solution Approach 1:
The patent uses magnetic field copying to create virtual ECG channels. By measuring the magnetic field generated by the heart and mathematically reconstructing it, the system creates additional virtual measurement channels without adding physical electrodes, thereby improving spatial resolution while maintaining equipment simplicity
Solution Approach 2:
The patent transitions from electrical measurement (conventional ECG) to magnetic field measurement (MCG). This dimensional change allows for better spatial resolution and provides additional information about cardiac electrical activity that cannot be obtained through traditional electrical electrodes alone
2Measurement precision
If high-resolution magnetocardiography (MCG) is used, then sufficient spatial information is provided, but the device is expensive and large in size
Solution Approach 1:
The patent creates virtual measurement channels through mathematical reconstruction of magnetic field data, eliminating the need for numerous physical sensors. This copying approach achieves high spatial resolution information without requiring a large array of physical MCG sensors, thus reducing device size
Solution Approach 2:
The patent makes a single portable MCG device serve multiple functions by using magnetic field measurements to provide information equivalent to multiple conventional ECG channels. This multi-functionality allows one compact device to replace what would otherwise require multiple separate measurement systems
3Measurement precision
If high-resolution magnetocardiography (MCG) is used, then sufficient spatial information is provided, but the device is expensive and large in size
Solution Approach 1:
The patent uses mathematical algorithms to copy and reconstruct cardiac electrical information from magnetic field measurements into virtual ECG channels. This computational copying provides high-resolution spatial information without requiring complex physical sensor arrays, thereby reducing overall device complexity
4Reliability
If static ECG is used for diagnosis, then the equipment is simple, but it only alerts when cardiac hypoxia happens and cannot provide real-time prediction
Solution Approach 1:
The patent implements continuous real-time monitoring of cardiac magnetic fields, providing uninterrupted data collection and analysis. This continuous measurement capability enables early detection of cardiac abnormalities before they manifest as overt symptoms, improving reliability for early prediction while using a portable system that does not require complex hospital infrastructure

AI summary
A system and method for evaluating cardiovascular performance in real time and characterized by conversion of a surface potential into multi-channels are introduced. The system includes an electrocardiographic signal measuring unit, a reconstruction unit, and a parameter computation and assessment unit. The reconstruction unit reconstructs electrocardiographic signals (ECG signals) recorded by the electrocardiographic signal measuring unit, such that the ECG signals are reconstructed as ones located at different spatial positions but actually not having a channel. The method includes calculating a variation manifested spatially during an interval between a Q wave and a T wave of an ECG signal against time with a parameter computation and assessment algorithm, to evaluate its discreteness degree and thereby diagnose cardiovascular diseases (CVD) and locate lesions thereof.
