Solution Overview
Problem
Conventional micro-robot driving methods using magnetic fields are limited by small working areas, requiring larger coils or increased electrical energy, which restricts their application and efficiency due to physical limitations and energy consumption.
Innovation Solution
A system utilizing a transfer robot to expand and reposition a magnetic field generation system, allowing for wide-area control of micro-robots in 3D space without the need for high electrical energy or large coils, by integrating a magnetic field control unit, a transfer robot, and a control unit that receives and transmits position information for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the size of coils is increased to expand the working area, then the working area is expanded, but physical limitations are reached and device complexity increases
Solution Approach 1:
The system divides the working area expansion task into two parts: a fixed coil system that generates the magnetic field and a mobile transfer robot that carries the coil to different positions. This segmentation allows the working area to be expanded without permanently increasing the size of the coil system.
Solution Approach 2:
The transfer robot dynamically moves the coil system to different positions in space, transforming the static working area into a dynamic one that can be repositioned as needed. This allows the same coil to serve multiple spatial locations over time, effectively expanding the working area without increasing coil size.
2Area of stationary object
If higher electrical energy is supplied to expand the working area, then the working area is expanded, but energy consumption increases and control efficiency decreases
Solution Approach 1:
The system separates the functions of magnetic field generation (performed by the coil) and spatial coverage (performed by the transfer robot). This allows the coil to operate at optimal power levels while the robot handles the spatial expansion, avoiding the need to supply excessive energy to the coil system.
Solution Approach 2:
The system replaces the approach of using higher electrical energy to expand the magnetic field range with a mechanical approach: physically moving the coil system using the transfer robot. This substitution of mechanical motion for electrical energy expansion reduces power consumption while achieving the same working area expansion.
3Area of stationary object
If the size of coils is increased to expand the working area, then the working area is expanded, but the efficiency of control device and driver decreases
Solution Approach 1:
The transfer robot enables the coil system to dynamically access different working positions, maintaining high control efficiency at each position while collectively covering a larger area. The control device and driver operate efficiently at their optimal design point rather than being stretched to cover a larger area statically.
