Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual conversion and adjustment of X-ray optical elements is performed to switch between reflection and transmission geometries, then the measurement geometry can be changed, but the process becomes time-consuming and requires competent personnel
Solution Approach 1:
The patent implements motorized drives that automatically rotate the goniometer and adjust the optical elements between reflection and transmission geometries. This dynamic automation eliminates manual intervention, reducing conversion time while maintaining the ability to switch between different measurement geometries.
Solution Approach 2:
The system performs self-adjustment through automated control mechanisms. The motorized drives and control unit enable the X-ray optical structure to reconfigure itself between geometries without requiring external manual operation by competent personnel, thus reducing both time and skill requirements.
2Adaptability or versatility
If X-ray optical components are manually converted and stored when not in use, then different measurement geometries can be supported, but the risk of damage or loss increases
Solution Approach 1:
The patent designs the X-ray optical structure with universal mounting mechanisms and integrated storage positions within the goniometer system. Optical elements can be quickly swapped and stored in protected positions without manual handling, reducing the risk of damage while supporting multiple measurement geometries through the same hardware platform.
Solution Approach 2:
The patent introduces motorized drives and automated control systems as intermediaries between the operator and the optical components. These intermediaries handle the delicate operations of converting and storing components automatically, eliminating direct manual contact and thus reducing the risk of damage or loss during conversion and storage operations.
3Adaptability or versatility
If extensive manual adjustment is performed to switch between geometries, then the measurement geometry can be changed, but specialized personnel are required
Solution Approach 1:
The patent replaces manual mechanical adjustment operations with motorized drives and automated control systems. The motorized goniometer and optical element positioning mechanisms eliminate the need for specialized manual adjustment skills, making the system easier to operate while maintaining the ability to switch between different measurement geometries.
Solution Approach 2:
The system performs self-adjustment through automated control mechanisms. The motorized drives and control unit enable the X-ray optical structure to reconfigure itself between geometries without requiring external manual operation by competent personnel, thus reducing both time and skill requirements.
4Stability of the object's composition
If rigid connection of optical elements is used for structural stability, then alignment is maintained, but conversion between geometries becomes more complex
Solution Approach 1:
The patent segments the optical system into modular components (source, goniometer, optical elements, detector) that can be independently positioned and adjusted. The motorized drives provide stable alignment within each segment while enabling easy reconfiguration between geometries by moving entire modules, thus reducing conversion complexity while maintaining alignment stability.
Solution Approach 2:
The patent implements motorized drives that automatically rotate the goniometer and adjust the optical elements between reflection and transmission geometries. This dynamic automation eliminates manual intervention, reducing conversion time while maintaining the ability to switch between different measurement geometries.
