Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the C-arm is equipped with multiple degrees of freedom to enable movement from multiple positions and angles, then the examination capability is improved, but the risk of collision with patients, operators, or obstacles increases
Solution Approach 1:
The collision monitoring apparatus performs preliminary detection of the surrounding environment using cameras and image processing before the C-arm moves. By analyzing video images to identify patients, operators, and obstacles in advance, the system prepares collision prevention measures before movement occurs, allowing the C-arm to maintain its versatile movement capability while preventing collisions through pre-detection and pre-alarm mechanisms.
2Productivity
If the C-arm moves rapidly to improve examination efficiency, then the productivity is improved, but the severity of potential collisions increases
Solution Approach 1:
The collision monitoring apparatus establishes a real-time feedback loop by continuously capturing video images, processing them to detect potential collisions, and immediately providing feedback through alarm signals. This feedback mechanism allows the system to maintain high examination efficiency while dynamically responding to potential collision risks, enabling operators to adjust movement speed or direction based on real-time collision probability assessments.
3Reliability
If the C-arm is equipped with collision monitoring capabilities, then the safety is improved, but the device complexity increases
Solution Approach 1:
The collision monitoring apparatus replaces complex mechanical collision detection mechanisms with optical detection systems using cameras and image processing algorithms. This substitution reduces mechanical complexity while enhancing safety capabilities, as the optical system can detect a wider range of potential collisions without requiring physical sensors or complex mechanical interlocks on the C-arm structure.

AI summary
A collision monitoring apparatus can include a camera to acquire a video image of surroundings of at least one target protection component on the C-arm X-ray machine system; an image processor to determine a scene of the surroundings of the at least one target protection component according to the video image; and a controller to control a C-arm X-ray machine system to stop moving or slow down when it is determined that a possible collision exists according to the scene of the surroundings of the at least one target protection component. Advantageously the apparatus effectively prevents patients, operators, patient examination beds and other obstacles from suffering a serious collision with the C-arm itself.
