Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electromagnets are used to control microrobot motion, then control capability is improved, but device size and power consumption increase
Solution Approach 1:
The patent applies multi-functionality by enabling electromagnet modules to perform both position recognition and motion control functions. The dual hybrid electromagnet module generates both gradient magnetic fields for position recognition and uniform magnetic fields for motion control, allowing a single device to replace what would traditionally require separate systems, thereby reducing overall power consumption and device size while maintaining full control capability
Solution Approach 2:
The patent merges position recognition and motion control functions into a single dual hybrid electromagnet module. By combining gradient magnetic field generation (for position recognition) and uniform magnetic field generation (for motion control) in one integrated device, the system reduces the total number of electromagnets needed while maintaining both functions simultaneously
2Weight of stationary object
If permanent magnets are used to reduce electromagnet数量, then device size is reduced, but control performance deteriorates
Solution Approach 1:
The patent employs asymmetry by using different electromagnet configurations for different functions within the same module. The dual hybrid electromagnet module uses asymmetric winding arrangements where one electromagnet is optimized for generating gradient magnetic fields (position recognition) while the other is optimized for uniform magnetic fields (motion control), allowing each component to excel at its specific function while maintaining compact size
Solution Approach 2:
The patent applies dynamics by enabling real-time switching between different magnetic field configurations. The system can dynamically adjust the current applied to each electromagnet to generate either gradient fields for position recognition or uniform fields for motion control, providing adaptive control performance that responds to real-time operational requirements
3Measurement precision
If separate position recognition device is used, then position recognition accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges position recognition and motion control into a single dual hybrid electromagnet module. The same electromagnets that generate magnetic fields for motion control also generate gradient magnetic fields for position recognition, eliminating the need for separate position recognition devices and reducing system complexity while maintaining accurate position monitoring
Solution Approach 2:
The electromagnet module serves multiple functions: it generates uniform magnetic fields for motion control, generates gradient magnetic fields for position recognition, and enables real-time feedback control. This multi-functionality eliminates the need for separate dedicated position recognition devices, simplifying the overall system architecture
4Adaptability or versatility
If motor is used to control permanent magnet position, then control space is secured, but real-time control is delayed
Solution Approach 1:
The patent replaces mechanical motor systems with an electromagnetic field-based control system. Instead of using motors to physically move permanent magnets, the system uses electronically controllable electromagnets to generate magnetic fields that directly act on the microrobot, eliminating mechanical inertia and achieving real-time control response without mechanical movement delays
