Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by enabling a single X-ray source to perform multiple measurement functions at different depths through interchangeable anode materials. Each anode material (e.g., Cu, Mo, Ag) is selected based on the required penetration depth and measurement target, allowing the system to adapt to various crystallographic analysis requirements without requiring separate dedicated sources for each depth range

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces dynamic configurability through the ability to interchange anode materials in the X-ray tube. The carousel mechanism with multiple anode options allows the system to dynamically adjust its characteristics based on the specific measurement requirements, transitioning from a static single-source design to a dynamic multi-configuration system

Inventive Principle:
Principle #15Dynamics

Solution Approach 1:

The patent applies parameter changes by varying the X-ray energy parameters through different anode materials to achieve different penetration depths. By selecting appropriate anode materials with specific atomic numbers and emission characteristics, the system can penetrate to desired depths and obtain crystallographic information from subsurface regions without physically altering or destroying the sample

AI summary

An x-ray diffraction system (100) includes an x-ray source (102) having a first interchangeable x-ray generating component (104), a second interchangeable x-ray generating component (106), an actuator (108) and a controller (110) operatively connected to the actuator. The first and second interchangeable x-ray generating components (104, 106) are interchangeable with one another. The actuator (110) is operatively connected to the first and second interchangeable x-ray generating components (104, 106). A method for non-destructive x-ray diffraction includes emitting a first x-ray beam from an x-ray source with a first x-ray generating component based on a first desired depth to measure a crystallographic signature of a sample at the first desired depth, interchanging the first x-ray generating component (104) with a second x-ray generating component (106) to form a modified x-ray source, and emitting a second x-ray beam from the modified x-ray source based on a second desired depth, to non-destructively measure a crystallographic signature of the sample at the second desired depth.
