Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automatic positioning to a preset default state is used, then positioning speed is improved, but adaptability to individual differences between subjects deteriorates
Solution Approach 1:
The system performs preliminary actions by capturing optical images of the subject and analyzing physical characteristics before X-ray positioning. The specifying device analyzes the optical image to determine subject characteristics, and the positioning device uses this information to pre-calculate optimal positioning parameters, enabling both speed and adaptability.
Solution Approach 2:
The system implements feedback by using the optical image analysis results to adjust and optimize X-ray positioning. The specifying device provides feedback about subject physical characteristics to the positioning device, which then adjusts positioning parameters accordingly, creating a closed-loop system that adapts to individual subjects while maintaining efficiency.
2Adaptability or versatility
If manual positioning adjustment is performed to match subject constitution, then adaptability to individual differences is improved, but positioning time and complexity increase
Solution Approach 1:
The system replaces manual mechanical positioning adjustment with an automated optical analysis and computational positioning system. The specifying device uses optical image analysis to automatically determine subject characteristics, and the positioning device computationally determines optimal positioning parameters, eliminating time-consuming manual adjustments while maintaining high adaptability.
Solution Approach 2:
The system enables self-service positioning where the subject's own optical image is captured and analyzed to automatically determine the optimal X-ray positioning parameters. The subject essentially positions themselves through the optical analysis process, eliminating the need for operator intervention and reducing positioning time while maintaining adaptability.
3Measurement precision
If multiple support devices with multiple degrees of freedom are used, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The positioning device serves multiple functions: it receives optical image data, processes positioning parameters, controls multiple support devices with different degrees of freedom, and coordinates their movements. This multi-functional approach consolidates what would otherwise require separate systems, reducing overall complexity while maintaining high positioning accuracy through coordinated control of multiple degrees of freedom.
