Slanted Drawer Rail Layout for Close-Coupled X-Ray Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of telescopic rails in drawer housings for x-ray image-recording devices increases production costs without ensuring optimal positioning of the image-recording device, leading to suboptimal image quality due to larger distances between the device and other x-ray components.
Innovation Solution
A pull-out device with slanted guide rails and slots allows the drawer to move along a slanting plane, maintaining the drawer's floor parallel to the housing floor, enabling easier insertion and withdrawal while minimizing the distance between the image-recording device and other x-ray components, and using collets to fix the device in place during recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telescopic rails are used to enable full withdrawal of the drawer, then ease of operation is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive telescopic rails with a simpler, cheaper guide rail system that achieves the same functional outcome of enabling drawer withdrawal without requiring complex telescopic mechanisms
Solution Approach 2:
The patent extracts the essential function of telescopic rails (enabling drawer withdrawal) and implements it through a simplified guide rail mechanism, removing the unnecessary complexity of full telescopic functionality
2Manufacturing precision
If the drawer is positioned closer to minimize distance to x-ray components, then image quality is improved, but ease of placing image-recording device deteriorates
Solution Approach 1:
The patent implements a dynamic positioning system where the drawer can be easily withdrawn for loading and then positioned at the optimal close distance for imaging, allowing the system to adapt between two operational states
Solution Approach 2:
The guide rail system is pre-configured to guide the drawer into the correct position, making the placement of the image-recording device easier before the actual imaging process begins

AI summary
An arrangement includes a drawer housing and a drawer intended for an image-recording device of an x-ray-image device to be placed in the drawer. The arrangement includes a pull-out device, using which the drawer is moveable across a slanting plane while being withdrawn from or inserted into the drawer housing. A floor of the drawer remains parallel to a floor of the drawer housing.
