Dental X-Ray Support Positioning With Horizontal Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging devices in dentistry lack horizontal movement capability of the support unit, complicating the structure and causing inconvenience to both the examinee and the user, and increasing production costs.
Innovation Solution
The support unit is designed to move horizontally on an arbitrary reference plane based on the examinee's height, allowing easy positioning at desired imaging positions without a complex moving structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support unit is fixed vertically only, then the structure remains simple, but the examinee cannot be positioned at desired imaging positions horizontally
Solution Approach 1:
The support unit is transformed from a fixed structure to a movable one, enabling horizontal positioning adjustments. The support unit can move horizontally along the support frame while maintaining vertical support functionality, allowing dynamic adaptation to different imaging positions and examinee heights.
Solution Approach 2:
The positioning system is divided into independent components: the support frame provides vertical movement, while the support unit provides horizontal movement. This segmentation allows each component to perform its specific function independently, achieving complex positioning through coordinated simple movements.
2Adaptability or versatility
If a complex moving structure is added to enable horizontal movement of the support unit, then positioning flexibility improves, but production costs increase
Solution Approach 1:
The support frame and support unit are designed with multi-functionality. The support frame accommodates both vertical movement for height adjustment and horizontal movement for positioning. The support unit serves both as a support structure and as a horizontally movable positioning mechanism, eliminating the need for separate complex moving mechanisms.
Solution Approach 2:
The patent utilizes a simplified copying approach where the support unit replicates the essential movement functionality needed for positioning without requiring a fully independent complex mechanism. The horizontal movement capability is implemented through a simplified structure that copies the necessary degrees of freedom from more complex positioning systems.
3Adaptability or versatility
If the gantry moves to change imaging position, then imaging mode adaptability improves, but the structure becomes more complex and causes inconvenience
Solution Approach 1:
Instead of moving the gantry to achieve different imaging positions, the patent inverts the approach by moving the support unit with the examinee. This reversal of the movement target simplifies the gantry structure while achieving the same adaptability for different imaging modes and positions.

AI summary
Proposed is an X-ray imaging apparatus, which includes a main body, an X-ray generator and an X-ray detector connected to the main body and facing each other, for radiating and detecting X-rays toward an imaging position therebetween, a support unit for supporting a subject to be imaged, and a support portion for connecting the main body to the support unit and for positioning the subject to be imaged at an imaging height between the X-ray generator and the X-ray detector, wherein the support portion horizontally moves and positions the support unit at the imaging position according to an imaging mode. According to the configuration, there are effects of increasing the convenience of the examinee and user, reducing production costs, and increasing production efficiency, by freely moving the support unit supporting an examinee's body part on an arbitrary reference plane based on the examinee's height.
