Engineering Contradiction Analysis
1Productivity
If manual detector selection is used, then device complexity is reduced, but productivity decreases and user effort increases
Solution Approach 1:
The system automatically selects the appropriate X-ray detector by acquiring orientation information from sensors in both the radiation unit and detector, comparing their relative positions and orientations, and activating the optimal detector without user intervention. This self-service mechanism resolves the contradiction by automating the detector selection process, improving productivity while managing complexity through integrated sensing and control.
Solution Approach 2:
The system utilizes changes in orientation parameters (position and angle data from sensors) to dynamically determine which detector should be activated. By monitoring these parameter changes in real-time, the system can automatically select the appropriate detector based on the current geometric configuration, thereby improving imaging efficiency without requiring complex manual intervention.
2Loss of time
If manual detector selection is used, then device complexity is reduced, but loss of time increases
Solution Approach 1:
Orientation sensors in both the radiation unit and detectors continuously acquire and store position and orientation data before imaging is required. This preliminary action ensures that when imaging is needed, the system can immediately compare pre-acquired orientation information and activate the appropriate detector without delay, reducing time loss while managing complexity through proactive data collection.
Solution Approach 2:
The system establishes a feedback loop where orientation information from sensors continuously informs the control unit about the relative positions and orientations of the radiation unit and detectors. This real-time feedback enables automatic detector selection based on current geometric conditions, reducing the time required for detector selection while maintaining manageable system complexity through continuous monitoring and adjustment.
3Ease of operation
If manual detector selection is used, then radiation exposure is minimized, but user effort increases
Solution Approach 1:
The system automatically determines the optimal detector activation based on orientation information, eliminating the need for users to manually select detectors. This self-service capability reduces user effort while simultaneously minimizing radiation exposure by ensuring that only the necessary detector is activated, avoiding redundant exposures that might occur with manual selection errors or delays.
