Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image data is stored by an external image processing device in a form correlated with rotational magnetic field information, then image transmission and processing can be performed, but high-precision rotation correction cannot be achieved because the actual rotational state during image capture is not detected
Solution Approach 1:
A rotating angle detection device is introduced as an intermediary component that bridges the gap between the rotating medical device and the image processing system. This detector directly measures the rotational angle during image capture and transmits the data to the external processing device, enabling precise rotation correction without complicating the overall system architecture.
Solution Approach 2:
The patent replaces mechanical coupling methods (such as direct mechanical connection between the rotating device and detector) with a magnetic field-based detection system. The rotating angle detection device uses magnetic field sensing to non-contactly measure the rotational state, eliminating mechanical complexity while maintaining measurement precision.
2Measurement precision
If the rotational state is detected at the time of image capturing, then higher-precision rotation correction can be achieved, but the system complexity increases due to additional detection and synchronization components
Solution Approach 1:
The rotating angle detection function is merged with the existing rotational magnetic field generation system. The same magnetic field mechanism that rotates the medical device also serves as the reference for detecting its rotational angle, eliminating the need for separate detection hardware and reducing system complexity.
Solution Approach 2:
A feedback loop is established where the rotating angle detection device continuously monitors the rotational position and provides real-time data to the image processing device. This feedback enables dynamic rotation correction during image capture, ensuring high precision without requiring complex pre-programming or post-processing adjustments.
3Productivity
If image rotation processing is performed based on correlated rotational field data, then image processing can be done, but the actual image capturing timing and rotational angle are not accurately matched
Solution Approach 1:
The rotating angle detection device performs preliminary detection of the rotational angle at the exact moment of image capture. By detecting the rotational state in advance and synchronizing it with the image capture timing signal, the system ensures that the correct rotational data is available for immediate processing without timing mismatches.
Solution Approach 2:
The system uses periodic synchronization signals that coincide with the rotational cycle of the medical device. Image capture and angle detection are triggered at regular intervals synchronized with the rotation period, ensuring that each processed image corresponds to the correct rotational phase.
