Detachable X-Ray Alignment Guide for Multi-View Subject Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray radiography apparatuses require replacement or adjustment of the subject's radiography position when changing radiography methods, as different types of X-ray images necessitate different subject alignment devices.
Innovation Solution
A subject alignment device with a detachable guide unit that can be replaced and coupled depending on the type of X-ray images, allowing for the same apparatus to be used for multiple types of X-ray imaging without changing the entire apparatus or subject position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different subject alignment devices are used for different types of X-ray images, then the alignment accuracy for each specific radiography type is improved, but the device complexity and the need for multiple apparatuses increases
Solution Approach 1:
The subject alignment device is divided into a common guide part and interchangeable guide units. The guide part provides universal support structure while different guide units (such as temple supports, guide frames, or ear rod holders) can be attached based on the specific radiography type, enabling precise alignment for each application without requiring complete separate apparatuses
Solution Approach 2:
The guide part is designed with universal coupling mechanisms that can accommodate multiple types of guide units. This allows a single base apparatus to perform multiple alignment functions by simply changing the guide unit, thereby maintaining alignment accuracy across different radiography types while reducing overall device complexity
2Measurement precision
If the entire radiography apparatus is replaced when changing radiography methods, then the alignment is optimized for the new method, but the loss of time and operational efficiency decreases
Solution Approach 1:
The system transitions from a static, fixed configuration to a dynamic, reconfigurable system. The detachable guide units can be quickly attached and detached from the guide part, allowing the apparatus to adapt to different radiography methods without complete replacement, thus minimizing reconfiguration time while maintaining alignment precision
3Measurement precision
If the subject's radiography position is changed for different radiography types, then the alignment is optimized for each type, but the ease of operation and convenience decreases
Solution Approach 1:
The guide part serves as an intermediary component that standardizes the interface between the radiography apparatus and different guide units. This intermediary structure allows various guide units to be mounted on a common platform, enabling alignment optimization for different radiography types without requiring the subject to change positions or the entire apparatus to be reconfigured
