Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In X-ray fluorescence analyzers, operators face difficulties in accurately positioning samples with the same shape or in line patterns due to the complexity of visually counting and recognizing samples during movement, leading to potential errors in measurement.
Innovation Solution
An X-ray fluorescence analyzer system that includes a sample stage, moving mechanism, X-ray source, detector, imaging device, display device, pointing device, and control unit, which synchronizes the movement of a mark on the screen with the sample stage, allowing for precise positioning and easy confirmation of measuring points by displaying marks such as numbers or symbols as reference points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual counting of samples is performed during sample stage movement, then sample positioning can be achieved, but the operation becomes complicated and confirmation of correct measuring point is difficult
Solution Approach 1:
The patent creates a virtual copy of the sample arrangement by displaying marks at corresponding positions on the screen. These marks represent the actual sample locations, allowing operators to easily identify and count samples without direct visual inspection during movement. The mark display serves as a simplified copy that resolves the complexity of real-time visual counting.
Solution Approach 2:
The patent introduces marks as an intermediary element between the sample stage and the operator. Instead of directly observing and counting samples during movement, operators interact with the mark display which mediates the positioning task. This intermediary simplifies the interface and makes confirmation of measuring points straightforward.
2Productivity
If sample stage is moved to position multiple samples, then measurement of multiple samples is enabled, but it becomes difficult to recognize which sample is being checked
Solution Approach 1:
The patent uses visual marks with distinct appearances (described as having different colors or patterns) to represent different sample positions. These marks provide clear visual differentiation between samples, allowing operators to easily identify which sample is currently being measured even as the stage moves between multiple samples.
Solution Approach 2:
The mark display creates a visual map that copies the spatial arrangement of samples. This copied representation preserves sample identification information in a form that is easy to interpret during movement, preventing loss of identification information while enabling efficient multi-sample measurement.
3Ease of operation
If marks are displayed on screen to indicate sample positions, then positioning is simplified, but the mark position must be synchronized with sample stage movement
Solution Approach 1:
The patent implements a feedback mechanism where the mark display is continuously updated based on the sample stage position. The control unit receives position information from the stage and automatically adjusts mark positions on the screen accordingly. This feedback loop maintains synchronization without requiring complex manual coordination.
Solution Approach 2:
The patent replaces manual mechanical positioning and visual tracking with an automated electronic system. Instead of operators manually tracking sample positions, the control unit electronically manages mark display synchronization with stage movement, substituting mechanical/visual coordination with automated electronic control.

Function Achieved in This Case
This solution simplifies the positioning of X-ray radiation points and ensures accurate measurement by maintaining the relative position between the sample and the mark on the screen, even during sample stage movement, thereby improving operability and reducing errors when measuring multiple samples with the same shape or in line patterns.
