Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ECG devices use multiple electrodes and complex configurations, then diagnostic accuracy is maintained, but device complexity and cost increase
Solution Approach 1:
The cardio enclosure electrodes are designed to serve multiple functions: they form the basis for generating all six precordial leads (V1-V6) through computational processing, eliminating the need for separate precordial electrodes. This multi-functional approach maintains diagnostic accuracy while reducing the number of physical electrodes required.
Solution Approach 2:
The patent replaces the mechanical/electrical system of multiple physical electrodes with a computational system. Instead of using separate precordial electrodes to directly measure voltages, the device uses cardio enclosure electrodes combined with signal processing algorithms to computationally generate precordial lead signals, substituting physical complexity with computational processing.
2Reliability
If conventional ECG devices use multiple electrodes, then complete heart activity coverage is achieved, but cost and ease of use deteriorate
Solution Approach 1:
The cardio enclosure electrodes serve as universal measurement points that can derive all necessary precordial lead information through computational processing. This approach ensures complete heart activity coverage while simplifying the electrode application process for users.
3Measurement precision
If conventional ECG devices use multiple electrodes, then comprehensive lead signals are generated, but manufacturing cost increases
Solution Approach 1:
The patent extracts and eliminates the unnecessary precordial electrodes from the conventional ECG system. By keeping only the cardio enclosure electrodes and adding computational processing, the device achieves the same lead signal completeness at lower manufacturing cost.
Solution Approach 2:
The patent substitutes physical electrodes with computational signal generation. Instead of manufacturing and installing multiple types of electrodes, the system uses a reduced set of electrodes combined with digital signal processing to generate all necessary precordial leads, reducing manufacturing complexity and cost.
