Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ray sources are adopted to emit rays in different views, then multi-view scanning capability is improved, but device complexity and total weight increase
Solution Approach 1:
The patent merges multiple ray generation functions into a single ray source by integrating multiple accelerating tubes (differentiating tubes) with different beam exit directions into one unified structure. This allows the single ray source to emit rays in multiple directions simultaneously, achieving multi-view scanning capability while reducing the number of separate ray sources and associated mechanical structures
Solution Approach 2:
The single ray source with multiple accelerating tubes serves multiple functions: it can emit rays in different directions (at least two different beam exit directions) and with different energies (through selective activation of accelerating tubes). This multi-functional design eliminates the need for multiple dedicated ray sources for different viewing angles
2Adaptability or versatility
If multiple ray sources are adopted to emit rays in different views, then multi-view scanning capability is improved, but total weight increases
Solution Approach 1:
The patent combines multiple ray generation units into a single integrated ray source structure, where multiple accelerating tubes are housed within one common framework. This merging reduces the total weight by eliminating redundant structural components, support systems, and alignment mechanisms that would be required if separate ray sources were used
3Adaptability or versatility
If a mechanical structure is adopted to move a ray source, then multi-view scanning is achieved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical movement systems with an electronic control system. Instead of physically moving a single ray source to different positions, the system uses a processor to selectively activate different accelerating tubes within the single ray source, each having a fixed but different beam exit direction. This electronic switching approach eliminates complex mechanical translation stages, motors, and positioning mechanisms
