X-Ray Diffraction Sample Holder for Gas-Tight Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample holders for X-ray diffraction experiments lack ease of filling, robustness, and gas-tightness, making them difficult to use and transport samples securely.
Innovation Solution
A sample holder design with a front and back part that can transition from an open state for easy filling to a closed, gas-tight state, using foils with polymer and metal layers to seal the cavity, ensuring robust and secure sample containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing sample holder designs are used, then the structure is simple, but the ease of filling and gas-tightness are insufficient
Solution Approach 1:
The sample holder is divided into a front part and a back part that can be separated. The front part can be removed to allow easy filling of the sample cavity, while the back part remains stationary. This segmentation enables simple operation for sample loading without requiring complex filling mechanisms.
Solution Approach 2:
The foils are pre-installed on the front and back parts before assembly. This preliminary preparation allows the sample cavity to be quickly sealed when the parts are joined, eliminating the need for complex sealing mechanisms during the filling process.
2Reliability
If existing sample holder designs are used, then the structure is simple, but the robustness and security for transport are insufficient
Solution Approach 1:
Thin foils with polymer and metal layers are used to seal the sample cavity. These flexible films provide effective gas-tight sealing while maintaining a compact and robust structure suitable for secure transport of samples.
Solution Approach 2:
The foils are constructed as composite materials with both polymer and metal layers. This combination provides enhanced gas-tightness and mechanical strength, ensuring robust sample containment while keeping the overall structure relatively simple.
3Reliability
If foils with polymer and metal layers are used, then gas-tightness is improved, but manufacturing complexity increases
Solution Approach 1:
The foils are manufactured with specific thickness parameters for the polymer and metal layers to achieve the required gas-tightness. By optimizing these dimensional parameters, effective sealing is obtained while maintaining manufacturability through standard thin-film deposition processes.
