3-Joint Aligning Bite for X-ray Imaging Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray devices require significant repositioning of the X-ray generator and detector to image different areas of interest, such as anterior teeth and molars, leading to a complex driving mechanism and limited operating range.
Innovation Solution
The aligning bite features a 3-joint structure with a link frame that allows for folding and adjustable bite piece, enabling precise alignment of multiple areas of interest to a single imaging focus point, reducing the need for extensive repositioning and simplifying the driving mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the X-ray generator and detector are repositioned to image different areas of interest (anterior teeth, molars), then the imaging coverage is improved, but the driving mechanism becomes complex and the operating range is limited
Solution Approach 1:
The aligning bite introduces a dynamic 3-joint mechanism (first joint, second joint, third joint) that allows the bite piece to be adjusted to multiple positions and angles. This dynamic structure enables the system to adapt to different imaging areas (anterior teeth, molars, etc.) without requiring complex repositioning of the entire X-ray generator and detector assembly, thereby reducing driving mechanism complexity while maintaining imaging versatility
Solution Approach 2:
The aligning bite is segmented into multiple independent components: a bite stand, a support unit with link frame, and a bite unit with bite piece. Each segment can be independently adjusted through its respective joints, allowing precise positioning of the bite piece to align different areas of the subject's mouth with the imaging focus point. This segmentation enables versatile imaging coverage without requiring the entire device to be repositioned
2Adaptability or versatility
If the X-ray generator and detector are repositioned to image different areas of interest, then the imaging coverage is improved, but the operating range requirements increase
Solution Approach 1:
The dynamic 3-joint aligning bite mechanism allows the bite piece to reach multiple positions (anterior teeth, molars, etc.) through coordinated movement of the first, second, and third joints. This enables the imaging system to cover a wide range of areas without requiring the X-ray generator and detector to traverse a large operating range, as the alignment is achieved through the bite adjustment rather than extensive device repositioning
Solution Approach 2:
The aligning bite acts as an intermediary device between the subject and the X-ray imaging system. By adjusting the bite piece position and orientation, it brings different areas of the subject's mouth into alignment with the fixed imaging focus point, eliminating the need for the X-ray generator and detector to move across a large operating range to image different areas
3Device complexity
If the aligning bite uses a fixed structure, then the device complexity is reduced, but the alignment precision for multiple areas of interest deteriorates
Solution Approach 1:
The aligning bite employs a dynamic structure with three adjustable joints instead of a fixed structure. The first joint connects the link frame to the bite stand, the second joint connects the bite unit to the link frame, and the third joint allows folding of the link frame. This dynamic configuration enables precise alignment of multiple areas of interest (anterior teeth, molars, etc.) with the imaging focus point while maintaining manageable device complexity through modular design
Solution Approach 2:
The aligning bite is divided into segmented components (bite stand, support unit, bite unit) connected by independent joints. This segmentation allows each component to be adjusted independently to achieve precise alignment for different imaging areas, providing high measurement precision without requiring an overly complex monolithic structure

AI summary
An aligning bite of an X-ray device for aligning a subject to an X-ray imaging point and an X-ray device having the same are disclosed. The aligning bite of an X-ray may include a support unit being rotatably connected to a bite stand supporting the aligning bite, and a bite unit being rotatably connected to the support unit, wherein the support unit may include a link frame supporting the bite unit by connecting the bite unit to the bite stand, a first joint rotatably connecting one side of the link frame to the bite stand, a second joint rotatably connecting the bite unit to another side of the link frame, and a third joint being provided between the first joint and the second joint so as to allow the link frame to be folded.
