X-ray Wall Stand Rotary Bracket for Stretcher Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall stands for X-ray imaging either collide with overhead tube systems when used alone or have an oversized footprint when designed to work with stretcher tables, and they require manual movement of stretcher tables for panoramic radiographs, causing operational complexity and patient discomfort.
Innovation Solution
A wall stand with a column, a detector box, a support arm, a rotary shaft, a rotary bracket, and a drive mechanism that allows the detector box to move in a plane perpendicular to the rotary shaft, enabling it to be positioned correctly with a stretcher table without colliding with the overhead tube system and allowing for increased vertical movement without manual stretcher table repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a long support arm is designed to prevent collision with overhead tube system, then the wall stand can operate with stretcher table, but the footprint becomes overlarge
Solution Approach 1:
The detector box is nested within the space defined by the column and support arm structure. The rotary bracket allows the detector box to be positioned within the footprint of the wall stand while maintaining the necessary clearance from the overhead tube system when used with a stretcher table.
Solution Approach 2:
The invention introduces rotational movement around a vertical rotary shaft, adding a rotational dimension to the detector box positioning. This allows the detector box to reach positions that would otherwise require a longer support arm, thereby reducing the horizontal footprint while maintaining adaptability to stretcher table configurations.
2Area of stationary object
If a short support arm is used, then the footprint is reduced, but the top of column collides with overhead tube system when used with stretcher table
Solution Approach 1:
The support arm is made dynamically adjustable through the rotary bracket mechanism. The detector box can rotate around the vertical shaft to achieve the necessary clearance from the overhead tube system when working with stretcher tables, eliminating the need for a permanently long support arm and thus reducing the footprint.
3Device complexity
If detector box is stationary, then the structure is simplified, but manual movement of stretcher table is required for panoramic radiograph mosaicking
Solution Approach 1:
The detector box is made dynamically movable through the rotary bracket mechanism. The detector box can rotate around the vertical shaft to follow the movement of the stretcher table during panoramic radiograph acquisition, eliminating the need for manual stretcher table repositioning and simplifying the operational process.
4Device complexity
If manual movement of stretcher table is required, then the drive mechanism is simplified, but patient comfort deteriorates and operation becomes complex
Solution Approach 1:
The rotary bracket mechanism enables the detector box to automatically follow the stretcher table movement. The system serves itself by having the detector box rotate in coordination with the stretcher table position, eliminating the need for manual intervention and improving patient comfort during panoramic radiograph acquisition.
