Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital ECG data is stored in proprietary formats, then data storage and processing efficiency are improved, but compatibility and shareability across different manufacturers' systems deteriorate
Solution Approach 1:
The patent introduces an intermediary conversion system that translates proprietary digital ECG formats into standardized analog signals. This mediator device receives digital data from any manufacturer's system, converts it through a standardized intermediate format, and outputs compatible analog signals that can be processed by any ECG machine, thereby resolving the compatibility issue while maintaining processing efficiency
Solution Approach 2:
The system changes the parameter state of ECG data by converting from digital format (discrete values) to analog format (continuous signals). This parameter transformation allows the data to be universally accepted by analog-based ECG processing systems from different manufacturers, solving the compatibility problem while preserving the efficiency gains of digital storage
2Reliability
If additional ECG tests are performed for second opinions, then diagnostic accuracy is improved, but cost and time consumption increase
Solution Approach 1:
The patent creates a virtual copy of the original ECG test by converting the digital data back to analog signals that can be processed by a different manufacturer's system. This copying approach allows second opinions to be generated from the same original data without requiring the patient to undergo additional physical testing, thereby maintaining diagnostic reliability while eliminating time loss
Solution Approach 2:
The system performs preliminary conversion of digital ECG data to standardized analog format in advance, enabling multiple manufacturers to analyze the same data set. This preliminary action allows second opinions to be obtained without repeating the actual ECG test, saving time while ensuring diagnostic accuracy through multiple perspectives
3Adaptability or versatility
If digital to analog conversion is implemented, then compatibility and data sharing are improved, but device complexity increases
Solution Approach 1:
The patent designs a universal conversion system that can handle multiple proprietary digital formats and output to standardized analog signals. This multi-functional device serves as a universal interface between different manufacturers' systems, improving data sharing capability while managing complexity through standardized protocols and modular architecture
