Handheld X-ray Aiming Light Collimator Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held X-ray devices face challenges in accurately aligning the X-ray beam with the subject due to their narrow internal structure and the difficulty in mounting a collimator, leading to potential human side effects from long-term exposure and inaccuracies in X-ray photography.
Innovation Solution
A lightweight, rectangular collimator is positioned outside the emission hole, allowing for the adjustment and alignment of the aiming light, thereby simplifying the display of the X-ray irradiation area without the need for complex collimator structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex collimator structure using reflection mirror or aperture is adopted, then the X-ray beam alignment accuracy is improved, but the device complexity and internal structure requirements increase
Solution Approach 1:
The patent extracts the collimation function from a complex internal structure and implements it through a simple aperture hole in the emission hole cover. This separates the collimation function from the need for reflection mirrors or complex aperture mechanisms, achieving beam alignment accuracy while significantly reducing device complexity.
Solution Approach 2:
The emission hole cover is segmented into functional components: the cover itself, the aperture hole, and the LED positioning structure. This segmentation allows the collimation function to be independently implemented through the aperture hole while the LED positioning is handled separately, simplifying the overall structure.
2Measurement precision
If a complex collimator structure is used, then the X-ray beam alignment accuracy is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The collimation function is extracted and implemented as a simple aperture hole in the emission hole cover, eliminating the need for complex collimator assemblies. This significantly simplifies manufacturing and assembly processes while maintaining beam alignment accuracy.
Solution Approach 2:
The collimation function is merged with the emission hole cover structure itself. The aperture hole is directly formed in the cover, combining the cover and collimator functions into a single integrated component, thereby simplifying manufacturing.
3Measurement precision
If the emission hole cover structure is added, then the aiming light display accuracy is improved, but the device weight increases
Solution Approach 1:
The emission hole cover is designed as a thin structural component that provides the necessary functionality for LED positioning and aiming light display without adding significant weight. The thin film structure maintains structural integrity while minimizing mass.
Solution Approach 2:
The emission hole cover serves multiple functions: it acts as a structural component, provides LED positioning, enables aiming light display, and provides collimation through the aperture hole. This multi-functionality reduces the need for additional separate components, thereby minimizing weight increase.
