Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex fixing device is used for the ray source assembly, then the device can provide stable support, but the structure becomes complicated and adjustment accuracy deteriorates
Solution Approach 1:
The base is divided into an upper plate and a lower plate that can move relative to each other, allowing independent adjustment of the ray source assembly's position and orientation while maintaining stable support
Solution Approach 2:
The upper and lower plates are designed to be movable relative to each other, transforming the static complex fixing device into a dynamic adjustable system that achieves both stability and precision
2Reliability
If a complex fixing device is used for the ray source assembly, then the device can provide stable support, but the device becomes difficult to adjust
Solution Approach 1:
The fixing device is segmented into movable upper and lower plates with independent adjustment mechanisms, making the device easier to adjust while maintaining stable support for the ray source assembly
Solution Approach 2:
The dynamic movable connection between upper and lower plates transforms a static complex structure into an adjustable system that is both stable and easy to operate
3Device complexity
If the ray source assembly position is fixed, then the structure is simple, but the imaging quality deteriorates due to poor adjustment accuracy
Solution Approach 1:
The simple fixed structure is transformed into a dynamic adjustable system with movable upper and lower plates, achieving high positioning accuracy without excessive structural complexity
Solution Approach 2:
The base is segmented into movable plates that can adjust independently, providing precise positioning capability while maintaining overall structural simplicity
