Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid C-arm structure supporting both x-ray source and detector is used, then structural stability is improved, but device complexity and space requirements increase
Solution Approach 1:
The rigid C-arm structure is divided into two separate pivotable arms: one arm supports the x-ray source and the other arm supports the detector. Each arm can be adjusted independently, eliminating the need for complex adjustment mechanisms within a single rigid structure while maintaining structural stability during imaging.
2Stability of the object's composition
If a rigid C-arm structure is used, then structural stability is improved, but flexibility and adjustment capabilities worsen
Solution Approach 1:
The system employs two pivotable arms with independent adjustment capabilities, allowing dynamic repositioning of the x-ray source and detector relative to each other and to the patient. This enables the system to adapt to various imaging angles and configurations while maintaining structural stability during each imaging position.
3Device complexity
If heavy machine parts are moved as a whole, then adjustment capability is reduced, but device complexity is simplified, yet flexibility worsens
Solution Approach 1:
Instead of moving a heavy C-arm structure as a whole, the system segments the structure into two lighter pivotable arms that can be adjusted independently. Each arm can be moved and positioned separately, significantly improving flexibility and adaptability while reducing the complexity of adjustment mechanisms compared to moving a single heavy structure.
4Device complexity
If limited rotation is implemented, then device complexity is reduced, but image reconstruction quality worsens
Solution Approach 1:
The system allows for extensive rotation and positioning of the two arms around the patient, enabling acquisition of x-ray images from multiple angles and positions. This dynamic capability provides sufficient data for high-quality cross-sectional image reconstruction while maintaining manageable device complexity through the use of standard pivotable arm mechanisms.

AI summary
An x-ray system is provided. The x-ray system includes an x-ray emitter which can be adjusted by at least one arm as a first x-ray component and a recording system which can be adjusted independently of the at least one arm. The recording system may be adjusted by at least one additional arm as the further x-ray component. The two arms can be pivotably mounted about a common axis of rotation.
