Solution Overview
Problem
Mobile radiographic imaging systems, such as C-arm imaging systems, face challenges with vibration-induced motion blur due to the lack of effective damping mechanisms, leading to decreased image quality and increased imaging time.
Innovation Solution
A vibration damping assembly is integrated into the mobile radiographic imaging system, featuring a pivot element coupled to the toe portion and a damping element that interfaces with the ground surface, utilizing springs and damping pads to absorb vibrations, thereby reducing the amplitude and decay time of vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile radiographic imaging systems are designed to be easily transportable with moving parts, then flexibility and ease of repositioning are improved, but vibration-induced motion blur and image quality deteriorate
Solution Approach 1:
The patent introduces a vibration damping assembly as an intermediary component between the mobile support system and the C-arm imaging system. This assembly includes damping elements that absorb vibrations generated during movement, preventing them from reaching the imaging components. The damping assembly acts as a mediator that isolates the sensitive imaging system from the vibrations caused by the mobile support structure, thereby maintaining image quality while preserving mobility and flexibility.
2Measurement precision
If vibration damping mechanisms are added to reduce motion blur, then image quality is improved, but device complexity increases
Solution Approach 1:
The vibration damping assembly is designed as a separate, modular segment that can be independently integrated into the mobile radiographic imaging system. The damping elements are positioned at specific locations where vibrations are most problematic, creating segmented damping zones rather than a complex distributed system. This segmentation allows for targeted vibration control with minimal additional complexity.
Solution Approach 2:
The damping elements are designed to automatically absorb vibrations without requiring external control systems, sensors, or active adjustment mechanisms. The passive damping mechanism self-regulates based on the vibration inputs it receives, eliminating the need for complex control electronics or manual intervention. This self-service approach provides effective vibration damping while keeping the system simple and reliable.
3Reliability
If vibration damping assembly is integrated into the toe portion, then vibration-induced component degradation is reduced, but the interface complexity between damping elements and ground surface increases
Solution Approach 1:
The damping elements are designed to convert harmful vibrations into beneficial damping forces that protect the imaging components. By positioning the damping assembly at the toe portion where vibrations first contact the system, the design transforms the ground surface interface from a source of harmful vibrations into a controlled damping interface. The damping elements absorb and dissipate vibration energy, converting it into heat, thereby protecting components from vibration-induced degradation while maintaining a relatively simple interface design.
