Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional electromagnetic field driving apparatuses use numerous electromagnets to drive micro-robots, then the driving capability is improved, but the size of the apparatus increases and power consumption becomes very high
Solution Approach 1:
The patent combines multiple electromagnets into an integrated electromagnetic field apparatus with a unified control system. The apparatus integrates first, second, and third electromagnets that work together to generate coordinated magnetic fields for micro-robot driving, reducing the overall apparatus size while maintaining driving capability through synchronized operation of the combined electromagnet system.
Solution Approach 2:
The electromagnetic field apparatus is designed to perform multiple functions simultaneously: it can drive micro-robots, recognize their locations through magnetic field sensing, and provide real-time feedback control. This multi-functionality eliminates the need for separate driving and sensing apparatuses, reducing overall system size and power consumption while maintaining comprehensive control capability.
2Power
If conventional electromagnetic field driving apparatuses use numerous electromagnets, then the driving control is improved, but the number of power supplies and required output increases, leading to very high power consumption
Solution Approach 1:
The patent implements a feedback control system where the electromagnetic field apparatus not only drives the micro-robot but also senses its location through magnetic field measurements. The control unit processes this feedback information and adjusts the electromagnet currents in real-time, enabling precise driving control with optimized power consumption by only activating necessary electromagnets based on current robot position and desired trajectory.
Solution Approach 2:
The apparatus uses dynamic current control to the electromagnets based on real-time robot position and movement requirements. Instead of maintaining constant high power output from all electromagnets, the system dynamically adjusts current magnitude and activation patterns, reducing overall power consumption while maintaining precise driving control capability when needed.
3Power
If existing electromagnetic field driving apparatuses are used, then micro-robot driving is achieved, but there are difficulties in compatibility with equipment used in other medical facilities due to size limitations and magnet arrangement
Solution Approach 1:
The electromagnetic field apparatus is divided into modular segments with distinct functional zones. The first, second, and third electromagnets are arranged in separate but coordinated modules that can be independently controlled. This segmentation allows the apparatus to adapt to different medical facility configurations and integrate with various existing medical equipment while maintaining driving functionality.
Solution Approach 2:
The patent employs asymmetric arrangement of electromagnets optimized for the specific application environment. Rather than using symmetric configurations that require large clearance in all directions, the electromagnets are positioned asymmetrically to match typical medical facility equipment layouts, improving compatibility with X-ray devices and other medical equipment while maintaining driving capability.
4Measurement precision
If conventional location recognition methods are used, then location information can be obtained, but the process is cumbersome and difficult to implement in real-time
Solution Approach 1:
The patent merges the location recognition function into the electromagnetic field driving apparatus itself. The same electromagnets used for driving generate the magnetic field that is sensed by the micro-robot for location determination. This integration eliminates separate sensing apparatuses and simplifies the location recognition process, enabling real-time operation without time-consuming external measurement procedures.
Solution Approach 2:
The electromagnetic field apparatus performs location recognition using its own generated magnetic field. The micro-robot senses the magnetic field characteristics (strength, direction, gradient) created by the electromagnets to determine its position, eliminating the need for external sensing equipment or complex imaging procedures. This self-service approach enables rapid, real-time location recognition.
