Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If sequential operations of locking switch and imaging switch are performed, then the anode can rotate at the required speed for X-ray imaging, but the X-ray imaging process becomes slow and inefficient
Solution Approach 1:
The controller automatically rotates the anode to the imaging rotation speed when the light irradiation operation unit is operated, before the actual X-ray imaging is triggered. This preliminary rotation eliminates the need for manual sequential operations of locking switch and imaging switch, allowing the anode to be ready for imaging immediately when the imaging switch is pressed.
2Ease of operation
If adjustments of irradiation range and position are performed after first stage pressing, then the imaging parameters can be optimized, but the anode rotation stops and imaging cannot be performed quickly
Solution Approach 1:
The controller maintains continuous anode rotation during the entire period from light irradiation operation through parameter adjustments to final imaging. The anode rotation speed is controlled to be maintained at the imaging rotation speed throughout this process, ensuring that when the imaging switch is pressed, the anode is already rotating at the required speed and imaging can proceed immediately without interruption.
