Tilting Arm Support for Imaging Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning systems for imaging devices face challenges in efficiently transitioning between vertical and horizontal positions, particularly due to changes in the center of gravity, which can make exams more difficult and require additional counterbalances, and often necessitate multiple systems for different exam types, while also occupying excessive space.
Innovation Solution
A tilting arm support system with a geared linkage and sprockets that maintains a constant center of gravity, allowing the imaging element to pivot between vertical and horizontal positions without significant vertical movement, using a first and second sprocket coupled by a chain linkage driven by a motor with encoder feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pivot point is located at the back surface of the receptor, then the system allows positioning in different orientations, but the center of gravity changes during position changes requiring large counterbalance weights
Solution Approach 1:
The patent applies the equipotentiality principle by designing a linkage mechanism that maintains the imaging portion's center of gravity at a constant vertical level during rotation between vertical and horizontal positions. The linkage connects the arm support to the imaging portion such that as the arm extends or retracts, the imaging portion rotates while its center of gravity remains at the same height, eliminating the need for large counterbalance weights and reducing the effect of gravity on the system.
2Adaptability or versatility
If the support mechanism allows extension outward from the wall, then table exams can be performed, but the system occupies excessive space when in vertical position
Solution Approach 1:
The patent applies the dynamics principle by designing a movable arm support that can dynamically extend and retract relative to the vertical support. The arm support rotates about a pivot point and can be positioned at different distances from the wall depending on the exam requirements. When a table exam is needed, the arm extends outward; when space is needed, the arm retracts toward the wall, allowing the system to adapt its footprint based on operational needs.
