Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environmental magnetic field shielding is implemented, then measurement precision of biomagnetic fields is improved, but device complexity increases
Solution Approach 1:
A gradiometer is introduced as an intermediary device to measure and compensate for environmental magnetic field noise. The gradiometer captures ambient magnetic field variations and provides correction signals that are subtracted from the biomagnetic field measurements, thereby improving measurement precision without requiring complex physical shielding structures
Solution Approach 2:
The harmful environmental magnetic field noise is extracted and separated from the biomagnetic field signal through digital signal processing. The system isolates the noise component using the gradiometer and removes it through subtraction, leaving only the desired biomagnetic field signal for analysis
2Productivity
If real-time diagnostic evaluation is provided, then productivity of cardiac diagnosis is improved, but device complexity increases due to advanced processing requirements
Solution Approach 1:
The system performs preliminary signal conditioning, filtering, and noise compensation during the data acquisition phase. By preparing and pre-processing the biomagnetic field signals in real-time as they are acquired, the system reduces the computational burden for subsequent diagnostic analysis, enabling faster overall processing without requiring excessively complex real-time analysis hardware
Solution Approach 2:
The computer system is designed to perform multiple functions including signal acquisition, noise filtering, gradiometer compensation, diagnostic analysis, and result generation within a single integrated platform. This multi-functionality consolidates what could be separate complex systems into one unified device, improving productivity while managing overall system complexity
