Angle Plate Specimen Holder for Nondestructive X-Ray Diffraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray diffractometer specimen holders are limited in their ability to measure bulk specimens without grinding, as they are primarily designed for powder forms, and often require interaction with OEM software and electric parts, which can be restrictive.
Innovation Solution
A specimen holder featuring an angle plate with one side coupling to the X-ray diffractometer's flange and the other positioning the specimen for measurement, allowing bulk specimens to be measured nondestructively without grinding, using moldable wax and spacers for height adjustment and incorporating features like threaded holes and movable stages for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing specimen holders designed for powder form are used, then powder diffraction analysis can be conducted, but bulk specimens cannot be measured without grinding
Solution Approach 1:
The specimen holder is designed with a universal mounting interface that can accommodate both powder specimens in shallow containers and bulk specimens of various sizes. The holder structure includes adjustable positioning features and interchangeable mounting plates that enable it to function with different specimen types without requiring separate specialized holders, thus resolving the contradiction between versatility and preparation complexity.
2Object-affected harmful factors
If bulk specimens are measured without grinding, then nondestructive measurement is enabled, but existing specimen holders lack the necessary positioning capabilities
Solution Approach 1:
The specimen holder incorporates adjustable and movable components including height-adjustable mounting plates, lateral positioning mechanisms, and rotatable specimen stages. These dynamic features allow the holder to adapt its configuration to accommodate bulk specimens of varying sizes and shapes while maintaining precise positioning accuracy, enabling nondestructive measurement without sacrificing positioning capability.
Solution Approach 2:
The specimen holder is divided into multiple independent functional modules: a base mounting plate, an adjustable specimen support platform, positioning clamps, and height adjustment mechanisms. This segmentation allows each component to be independently adjusted and optimized for specific bulk specimen requirements, providing precise positioning while avoiding the need for destructive specimen preparation.
3Measurement precision
If specialized specimen holders are used for specific measurement geometries, then measurement precision is improved, but adaptability to different specimen types is reduced
Solution Approach 1:
The specimen holder features dynamically adjustable components including height-adjustable mounting plates with threaded rods, lateral positioning mechanisms, and rotatable specimen stages. These adjustable features enable the holder to adapt its geometry for different measurement configurations (such as transmission, reflection, or grazing incidence geometries) while maintaining measurement precision, thus resolving the contradiction between precision and adaptability.

AI summary
Example specimen holders for X-ray diffractometer are disclosed. One example specimen holder includes an angle plate. The angle plate includes a first side and a second side. The first side and the second side are configured to join each other at an angle. The first side is configured to couple to a flange of an X-ray diffractometer, where the X-ray diffractometer includes a goniometer. The second side is configured to position a specimen in a measurement position for the X-ray diffractometer, where a rotation axis of the goniometer passes through a surface of the specimen.
