Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiological apparatuses require a flexible and adaptable table movement system that can adjust to various patient positions and examination conditions, while also optimizing space usage in diagnostic rooms, but existing solutions lack the necessary flexibility and simplicity.
Innovation Solution
A table movement system utilizing two obliquely arranged, non-hinged rods constrained by motorized carriages and a spring actuator, allowing for variable positioning and reduced motor torque requirements, enabling translation, elevation, and tilting of the table with precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two rods are hinged to each other at a central point to move the table, then the table movement is controlled, but the system complexity increases and flexibility is reduced
Solution Approach 1:
The system divides the table movement control into two independent rods (first rod and second rod) that are not hinged to each other. Each rod is independently constrained by motorized carriages sliding on separate rails, allowing separate control of table position and orientation without the complexity of a central hinge connection.
Solution Approach 2:
Motorized carriages act as intermediary elements between the rods and the table. These carriages slide on rails and provide controlled constraints on the rods, enabling precise table movement control while maintaining system simplicity and flexibility through decoupled mechanical elements.
2Stability of the object's composition
If the table movement system is designed for fixed positioning, then structural stability is achieved, but adaptability to various patient positions and examination conditions is reduced
Solution Approach 1:
The system transitions from fixed positioning to dynamic positioning by using motorized carriages that can slide along rails. The carriages are controlled by motors that receive commands from a control unit, enabling the table to adapt to various positions and orientations while maintaining stability through controlled mechanical constraints.
Solution Approach 2:
The table movement system is designed to perform multiple functions: positioning the table at different heights, angles, and locations to accommodate various patient positions and examination conditions. The independent rod and carriage mechanism provides universal adaptability while maintaining structural integrity.
3Measurement precision
If motorized carriages are used to constrain the rods, then precise table positioning is achieved, but the space required for rail installation increases
Solution Approach 1:
The system uses rails that extend in specific directions to constrain rod movement along desired paths. By orienting rails in appropriate dimensions and using carriages that slide along these rails, precise table positioning is achieved while optimizing space utilization in the diagnostic room.
