XRF Analyzer Test Stand with Multi-Orientation Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional test stands for XRF analyzers are inconvenient for viewing the screen and positioning samples, often requiring additional equipment like PCs or risking analyzer damage, and suffer from instability due to their design.
Innovation Solution
A configurable test stand that allows horizontal and vertical positioning of the XRF analyzer, with a stanchion and base that provides stability and adjustable sample placement, enabling easy access to the screen and secure sample positioning without the need for a PC connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the analyzer is attached underneath the analysis deck in a traditional test stand, then the structure is simple, but the screen is difficult to view and operate
Solution Approach 1:
The test stand allows the analyzer to be positioned in multiple orientations (horizontal or vertical) and at different heights, transforming a static structure into a dynamic one that adapts to user needs. The adjustable positioning mechanism enables the screen to be viewed and operated comfortably without requiring complex external equipment.
2Ease of operation
If a PC connection is used to control the analyzer, then screen visibility improves, but additional equipment and connection requirements increase complexity
Solution Approach 1:
The invention extracts the PC from the system entirely, making the test stand and analyzer self-sufficient. By repositioning the analyzer within the test stand structure, the screen becomes directly accessible without requiring external PC equipment, connections, or additional power sources.
3Ease of manufacture
If the sample is placed in a shielded container with the analyzer on top, then sample positioning is simplified, but the analyzer window risks being punctured by jagged samples
Solution Approach 1:
A sample holder acts as an intermediary between the sample and the analyzer window. This intermediate structure supports the sample securely while maintaining a safe distance from the fragile window, preventing direct contact that could cause punctures from jagged samples while still enabling proper sample positioning for analysis.
4Ease of operation
If a tripod structure is used to support the test stand, then the deck can be positioned for viewing, but clearance requirements increase height and stability decreases
Solution Approach 1:
The invention transitions from a vertical tripod structure to a horizontal tabletop configuration. By changing the primary support dimension from vertical legs to a horizontal base, the system eliminates the need for vertical clearance while improving stability through a lower center of gravity and broader base of support.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The test stand allows for robust and stable operation of XRF analyzers, ensuring safe and convenient sample analysis with clear visibility of the screen and proper sample placement, eliminating the need for additional equipment and reducing the risk of analyzer damage.
Implementation Method 1
a wedge feature as a soil sample retainer to help position the sample in front of the analyzer's measurement window
Implementation Method 2
the disclosed test stand has the benefit of using gravity to maintain the sample's contact with the analyzer's measurement window

AI summary
Disclosed is a test stand that supports and stabilizes a handheld XRF analyzer, and holds a body of sample to be tested. The test stand allows both horizontal and vertical analysis positions of the analyzer. The preferred embodiment of the test stand comprises a shielded X-ray chamber in which samples are tested and which affixes to the XRF analyzer's window via a spring loaded handle, a stabilizing base to which the analyzer's handle is situated, and a stanchion for horizontal mounting of the XRF analyzer. In the horizontal orientation, the chamber contains an adjustable platform and soil sample retainer to facilitate the positioning of the sample to be tested. The stanchion can be stored under the base.
