Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If imaging and treatment assemblies share a common rotation mechanism, then device complexity is reduced, but treatment precision deteriorates due to interference between imaging and treatment processes
Solution Approach 1:
The system divides the rotation mechanism into two independent parts: a first rotatable part for imaging assembly and a second rotatable part for treatment assembly. This segmentation allows each assembly to rotate independently without interfering with the other, thereby maintaining high beam alignment precision while managing device complexity through modular design.
Solution Approach 2:
The system merges the imaging and treatment assemblies into a single integrated device with coordinated rotation capabilities. The first and second rotatable parts are combined in such a way that they can operate independently yet simultaneously, achieving precise beam alignment while maintaining a unified device structure.
2Ease of operation
If imaging assembly obstructs treatment beam path, then imaging function is achieved, but treatment accuracy deteriorates
Solution Approach 1:
The imaging assembly is made dynamically movable relative to the treatment beam path through the first rotatable part. The imaging assembly can be rotated to appropriate positions before treatment, moved during treatment for real-time imaging, and repositioned after treatment, allowing it to adapt to different operational phases without compromising beam positioning accuracy.
3Ease of operation
If treatment assembly obstructs imaging path, then treatment function is achieved, but imaging efficiency deteriorates
Solution Approach 1:
The treatment assembly is made dynamically adjustable through the second rotatable part, allowing it to be positioned optimally for treatment delivery while minimizing obstruction of the imaging path. The independent rotation capability enables the treatment assembly to be moved out of the imaging path when imaging is required, thereby maintaining high imaging efficiency without compromising treatment capability.
