Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-precision image recognition is performed to recognize body position when parts of the subject are hidden, then measurement precision is improved, but productivity deteriorates due to requiring high computational power and long processing time
Solution Approach 1:
The body position recognition process is segmented into multiple determination steps based on receive coil information. The processor first determines body position using receive coil type, then progressively uses connection position and feature information only when needed, dividing the recognition task into hierarchical stages that balance accuracy and processing efficiency
Solution Approach 2:
Instead of performing full high-precision image recognition on all subjects, the system applies partial action by using receive coil information to determine body position in many cases, resorting to more complex image recognition only when necessary. This reduces overall processing requirements while maintaining sufficient accuracy
2Measurement precision
If comprehensive image recognition processing is applied to all subjects, then measurement precision is improved, but device complexity increases due to requiring additional high-performance computing devices
Solution Approach 1:
The receive coil serves multiple functions: it is used for its primary imaging purpose and simultaneously provides body position determination information. By utilizing the receive coil's connection position and type information, the system achieves body position recognition without requiring separate dedicated sensing devices, reducing overall system complexity
Solution Approach 2:
The receive coil itself provides the information needed for body position determination. The processor uses the receive coil's inherent characteristics (type, connection position) to determine body position, eliminating the need for external high-performance recognition devices. The system serves itself by using existing components for multiple purposes
