Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic field devices for controlling microrobots in medical procedures are inefficient due to high power consumption, heat generation, and limited control performance, particularly because they require multiple electromagnets and rely on permanent magnets with constant magnetization, making real-time magnetic field control challenging.
Innovation Solution
A dual hybrid electromagnet module system comprising a first and second hybrid electromagnet module, each with a permanent magnet and an electromagnet, arranged to intersect centrally, allowing for precise control of magnetic fields with reduced power consumption and heat generation by adjusting the current applied to the electromagnets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of electromagnets are used to control microrobot, then control coverage is improved, but device size and power consumption increase
Solution Approach 1:
The patent combines permanent magnets and electromagnets into a hybrid electromagnet module. The permanent magnet provides a base magnetic field while the electromagnet provides controllable adjustment, merging the advantages of both magnet types to achieve comprehensive control coverage with reduced power consumption compared to using only electromagnets.
Solution Approach 2:
The hybrid electromagnet module serves multiple functions: the permanent magnet component provides continuous magnetic field coverage while the electromagnet component provides adjustable control. This multi-functionality allows a single module to replace what would otherwise require multiple separate electromagnets, reducing overall power consumption while maintaining control coverage.
2Adaptability or versatility
If multiple electromagnets are used to control microrobot, then magnetic field control is improved, but heat generation increases
Solution Approach 1:
The patent merges permanent magnets and electromagnets into a hybrid module where the permanent magnet provides a stable base field without heat generation, while the electromagnet provides only the necessary incremental control field. This reduces the overall current required compared to using multiple electromagnets, thereby reducing heat generation while maintaining magnetic field control capability.
3Device complexity
If permanent magnets with constant magnetization are used, then device complexity is reduced, but real-time control performance deteriorates
Solution Approach 1:
The patent introduces an electromagnet component to the permanent magnet system, creating a hybrid electromagnet module. The electromagnet provides dynamic, adjustable magnetic field control that can be modified in real-time through current adjustment, while the permanent magnet maintains its constant field. This dynamic component enables real-time control performance improvement without significantly increasing overall device complexity.
Solution Approach 2:
The patent enables parameter changes in the magnetic field by using the electromagnet component to adjust the total magnetic field strength and direction. By changing the current in the electromagnet, the magnetic field parameters can be dynamically adjusted in real-time, overcoming the limitation of constant magnetization in permanent magnets while maintaining relatively simple device structure.
4Use of energy by stationary object
If the number of electromagnets is reduced, then power consumption is reduced, but control precision deteriorates
Solution Approach 1:
The patent merges the advantages of permanent magnets (energy efficiency) and electromagnets (control precision) into a hybrid electromagnet module. The permanent magnet provides a strong, stable base field that requires minimal power to maintain, while the electromagnet provides precise, adjustable control capability. This combination achieves both reduced power consumption and maintained control precision.
