Straight Arm X-Ray Stand Telescopic Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging stands face challenges in being installed in small spaces due to their fixed size and the need for large weight balances, which restricts their installation in buildings with limited ceiling height and requires increased size for arm length adjustments.
Innovation Solution
An X-ray imaging stand with a straight arm structure that is expandable and contractable, featuring a main arm with a gearless chain and chain connection blocks, allowing the X-ray detection module and tube to move in conjunction, maintaining weight equilibrium with equal weights on both sides, enabling installation in small spaces with minimal motive power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stand-type X-ray imaging apparatus uses a weight balance to enable smooth manual operation, then the X-ray imaging tube or detector can ascend and descend easily, but the size of the weight balance increases with the size of the X-ray imaging tube or detector, requiring an increased height of the stand
Solution Approach 1:
The patent applies dynamics by making the arm length adjustable through telescopic sections. The arm can be extended or retracted depending on the imaging requirements, allowing the stand to maintain a compact base height while providing sufficient reach when needed. This dynamic adjustment resolves the contradiction between needing a compact stand height and requiring sufficient arm reach for imaging operations.
2Adaptability or versatility
If the distance between the X-ray imaging tube and the X-ray detection module is increased by moving them, then the imaging range is improved, but a greatly increased length of the C-type arm or straight arm is required, increasing the overall size of the stand
Solution Approach 1:
The patent implements dynamics by incorporating telescopic sections in the arm that allow it to extend and retract. This enables the arm to achieve greater imaging distances when needed while maintaining a compact storage configuration, thus improving adaptability without permanently increasing the overall size of the stand.
Solution Approach 2:
The arm is divided into multiple telescopic sections that can extend independently. This segmentation allows the arm to achieve extended lengths for increased imaging range while collapsing to a compact form when not in use, resolving the contradiction between imaging range and overall size.
3Ease of manufacture
If the X-ray imaging stand is designed with a fixed size structure, then the structure is simple and easy to manufacture, but it cannot be installed in small spaces with limited ceiling height
Solution Approach 1:
The patent applies dynamics by making the arm length adjustable through telescopic sections. The arm can be extended or retracted depending on the imaging requirements, allowing the stand to maintain a compact base height while providing sufficient reach when needed. This dynamic adjustment resolves the contradiction between needing a compact stand height and requiring sufficient arm reach for imaging operations.
