Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mobile X-ray systems are used, then X-ray imaging function is provided, but the system has large footprint and is difficult to maneuver
Solution Approach 1:
The system divides the X-ray imaging functionality into separate modular components: a movable base with robotic arm for source positioning, a separate detector unit that can be independently positioned, and integrated control systems. This segmentation allows each component to be optimized for its specific function while reducing overall system footprint and improving maneuverability.
Solution Approach 2:
The system employs dynamic positioning capabilities with a movable base and robotic arm that can automatically adjust the X-ray source position. The robotic arm provides multiple degrees of freedom for precise positioning, and the base can be moved to different locations, enabling the system to adapt to various imaging scenarios without requiring a large fixed footprint.
2Extent of automation
If traditional mobile X-ray systems are used, then X-ray imaging function is provided, but alignment is difficult and manually intensive
Solution Approach 1:
The system incorporates sensors that detect the positions of both the X-ray source and detector, providing real-time feedback to the control system. The controller processes this position information and automatically adjusts the robotic arm and base positioning to achieve proper alignment, eliminating the need for manual alignment procedures.
Solution Approach 2:
The system performs self-alignment through automated control algorithms that calculate the optimal positioning of the X-ray source relative to the detector based on sensor data. The robotic arm and movable base automatically adjust their positions without requiring operator intervention, making the system self-sufficient in maintaining proper geometric alignment for imaging.
3Adaptability or versatility
If traditional mobile X-ray systems are used, then imaging function is provided, but controls are permanently installed limiting maneuverability
Solution Approach 1:
The control system is designed with universal accessibility, allowing operation from multiple positions and configurations. The controller can receive input from various user interfaces positioned at different locations, and the robotic arm can be controlled to achieve imaging from diverse angles and patient positions, making the system adaptable to different clinical workflows and user preferences.
Data Source
AI summary
A mobile X-ray system includes a movable base, a robotic arm mounted on the movable base, an X-ray source attached to the robotic arm, a radiation detector, one or more user interfaces, and a controller configured to determine a position of the X-ray source and a position of the detector and to automatically move the base and the robotic arm to align the X-ray source with the detector.
