X-ray Imaging Apparatus Mode Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging apparatuses require separate devices for standing and table modes, leading to increased installation costs and inefficient space utilization, as well as safety issues during mode switching.
Innovation Solution
An X-ray imaging apparatus with a pivotally fixed support frame and actuator allows for switching between standing and table modes using a single device, featuring a wire connection structure with closed loop wheels to prevent wire separation and a tiltable table for flexible imaging in limited spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate X-ray imaging apparatuses are installed for standing mode and table mode, then imaging functionality for each mode is ensured, but installation cost excessively increases and installation space is not efficiently utilized
Solution Approach 1:
The patent applies universality by designing a single X-ray imaging apparatus that can perform both standing mode imaging and table mode imaging through mode switching. The support frame can be pivoted between a vertical position (for standing mode) and a horizontal position (for table mode), allowing one device to replace what would traditionally require two separate apparatuses, thereby reducing installation cost and space while maintaining full imaging functionality.
2Ease of operation
If manual manipulation of X-ray detector is performed using a wire wound on a wheel, then ease of operation is improved, but wire separation from the wheel may occur during mode switching causing device damage and safety problems
Solution Approach 1:
The patent applies dynamics by changing the wheel's operational state based on the imaging mode. During mode switching between standing and table modes, the wheel is rotated to a predetermined position where the wire is disengaged from the wheel groove. This dynamic adjustment prevents the wire from being forcibly pulled or separated during mode transitions, eliminating the reliability issue while preserving the ease of manual detector manipulation during normal imaging operations.

AI summary
An X-ray photography device capable of readily photographing by switching to various photography modes such as a standing mode, a table mode and the like with one X-ray photography device is disclosed. To this end, the X-ray photographing device comprises: a base frame; a support frame pivotably coupled to one side of the base frame through a hinge shaft and on one side of which an X-ray detector for detecting X-rays irradiated from an X-ray generation device is slidably provided; and an actuator of which one end is rotatably fixed to the base frame and of which the other end is rotatably fixed to the support frame spaced at a predetermined distance from the hinge shaft, and which pivots the support frame around the hinge shaft within a predetermined angle range while moving a driving shaft therein forward and backward by pneumatic or hydraulic pressure supplied from the outside.
