Detachable X-Ray Alignment Guide Units for Multi-Mode Imaging
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 according to 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 type is improved, but the device complexity and time required for reconfiguration increase
Solution Approach 1:
The subject alignment device is divided into a base unit and multiple detachable guide units. Each guide unit is designed for specific types of X-ray imaging (e.g., cephalometric, panoramic, CT), allowing the system to maintain high alignment accuracy for each type while avoiding the complexity of having separate complete devices for each imaging type.
Solution Approach 2:
The base unit serves as a universal platform that can accommodate different types of guide units through standardized coupling mechanisms. This multi-functional design enables a single base unit to support various imaging types by simply changing the guide unit, thereby reducing overall device complexity while maintaining specialized alignment capabilities.
2Adaptability or versatility
If the entire radiography apparatus is replaced when radiography method changes, then the suitability for specific imaging type is improved, but the loss of time and operational efficiency increase
Solution Approach 1:
The system is segmented into a permanent base unit and interchangeable guide units. When imaging type changes, only the guide unit needs to be replaced rather than the entire apparatus, significantly reducing time loss while maintaining full adaptability to different imaging requirements.
Solution Approach 2:
The guide units are designed with detachable and attachable characteristics, allowing dynamic reconfiguration of the system based on imaging requirements. This dynamic adaptability enables quick switching between different imaging types without the time-consuming process of replacing entire apparatuses.
3Adaptability or versatility
If the subject's radiography position is changed when radiography method changes, then the suitability for specific imaging type is improved, but the operational complexity and time consumption increase
Solution Approach 1:
The alignment device is segmented into a base unit and specialized guide units. Each guide unit is optimized for specific imaging types and positions, allowing operators to simply attach the appropriate guide unit rather than repositioning the entire subject or complex apparatus, thereby maintaining ease of operation while improving adaptability.
