Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image recognition is performed on captured images to recognize body position, then body position recognition accuracy is improved, but processing time increases and computational resources are excessively consumed
Solution Approach 1:
The patent extracts and utilizes receive coil information (type and connection position) as a separate data source from captured images. By taking out this auxiliary information and using it to determine body position, the system achieves accurate recognition without relying solely on time-consuming image recognition processes
Solution Approach 2:
The patent introduces receive coil information as an intermediary element that mediates between the imaging system and body position determination. This intermediary provides direct positional cues that eliminate the need for extensive computational image analysis, thereby reducing processing time while maintaining accuracy
2Measurement precision
If high computational power is used to achieve high-precision image recognition, then body position recognition accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts receive coil information as a separate data source that provides direct body position indicators. By utilizing this extracted information, the system avoids the need for high computational power dedicated to image recognition, thereby reducing device complexity and cost
Solution Approach 2:
The receive coil system serves dual purposes: it performs its primary function of signal reception while simultaneously providing body position information. This self-service capability eliminates the need for separate high-computation image recognition systems, reducing overall device complexity
3Measurement precision
If multiple determination steps are performed to ensure accurate body position recognition, then recognition accuracy is improved, but processing time increases
Solution Approach 1:
The patent implements a dynamic determination process where the number of steps is adjusted based on receive coil information. When receive coil data is available and sufficient, the system performs fewer determination steps, thereby maintaining accuracy while improving imaging efficiency and reducing processing time
