Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic actuation systems face challenges in installation due to spatial interference with medical imaging devices, requiring a large arrangement space and limiting the increase in output magnetic field and magnetic force, especially in compact environments like C-arm X-ray systems.
Innovation Solution
A magnetic actuation system with a curved magnetic core and electromagnet array arranged in a planar configuration, where electromagnets are aligned in two rows with a separation space and a magnetic yoke connecting the rear ends, allowing for a reduced footprint and increased flexibility in arrangement, enabling the formation of a strong magnetic field and force while accommodating the movement paths of medical imaging devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If electromagnets are radially arranged to increase the number of electromagnets for stronger magnetic field, then the output magnetic field and magnetic force increase, but the arrangement space required increases making installation difficult in limited spaces
Solution Approach 1:
The electromagnets are arranged in a planar configuration rather than radial arrangement, transitioning from one-dimensional radial spacing to two-dimensional planar arrangement. This allows multiple electromagnets to be positioned in rows and columns, increasing the number of electromagnets that can be installed within a limited footprint while maintaining effective magnetic field generation toward the target position
2Force
If electromagnets are arranged radially to increase output magnetic field, then the magnetic field strength increases, but the device complexity and difficulty of installation increase due to spatial interference with medical imaging devices
Solution Approach 1:
By arranging electromagnets in a planar configuration with rows and columns rather than radial arrangement, the system simplifies installation by eliminating the need for complex radial positioning and spacing. The planar layout reduces spatial interference with medical imaging devices while maintaining the ability to generate strong magnetic fields through coordinated activation of multiple electromagnets
Solution Approach 2:
The electromagnet array is divided into multiple independent electromagnets arranged in rows and columns, allowing each electromagnet to be independently controlled and positioned. This segmentation enables flexible arrangement within limited space while maintaining the collective magnetic field strength needed for effective magnetic actuation
