Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CT, MRI, and PET imaging methods are used for stroke detection, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical imaging systems (CT, MRI, PET) with an electromagnetic imaging system that uses antennas and signal processing to detect brain anomalies. This substitution maintains diagnostic accuracy while significantly reducing device complexity and cost by using electromagnetic fields instead of mechanical scanning components.
Solution Approach 2:
The patent creates a simplified electromagnetic imaging system that copies the essential diagnostic function of complex medical imaging devices. By measuring electromagnetic properties of brain tissue, it reproduces stroke detection capability without requiring the complex infrastructure of CT, MRI, or PET scanners.
2Measurement precision
If CT, MRI, and PET imaging methods are used for stroke detection, then measurement precision is improved, but cost increases
Solution Approach 1:
The patent employs cost-effective electromagnetic imaging components that can be deployed widely without requiring expensive infrastructure. The system uses affordable antennas and signal processing equipment instead of costly medical imaging devices, making stroke detection accessible in resource-limited settings while maintaining diagnostic reliability.
3Measurement precision
If multiple antennas are used for 2D or 3D imaging, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the imaging task into multiple measurements using multiple antennas, where each antenna contributes to different aspects of the electromagnetic field mapping. This segmentation allows high-resolution imaging through coordinated simple measurements rather than requiring a single complex imaging device.
Solution Approach 2:
The patent designs the antenna system to perform multiple functions: different antennas can transmit and receive signals, and the same antenna array can be used for both 2D and 3D imaging modes. This multi-functionality reduces overall system complexity compared to having separate specialized devices for each imaging mode.
