Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple electromagnets are used to drive microrobot, then microrobot control precision is improved, but device size becomes bulky
Solution Approach 1:
The patent merges multiple electromagnet functions into a single integrated electromagnet structure. The electromagnet includes first and second coils wound in different directions around the same magnetic core, allowing it to generate magnetic fields in multiple directions simultaneously. This combining approach maintains the ability to control microrobot movement precision while significantly reducing the device footprint compared to using separate electromagnets for each direction.
Solution Approach 2:
The single electromagnet structure serves multiple functions by controlling microrobot movement in different directions. The first coil controls movement in one direction while the second coil controls movement in another direction, allowing one electromagnet to replace what would traditionally require multiple separate electromagnets. This multi-functionality resolves the contradiction by maintaining control precision across multiple axes without proportionally increasing device size.
2Measurement precision
If multiple electromagnets are used to drive microrobot, then microrobot movement control is improved, but power consumption increases
Solution Approach 1:
The patent combines multiple electromagnet functions into a single electromagnet with multiple coils sharing a common magnetic core. This merging reduces the total number of independent electromagnet systems required, thereby reducing cumulative power consumption while maintaining the ability to control microrobot movement in multiple directions with high precision.
Solution Approach 2:
The electromagnet structure performs multiple control functions simultaneously through its first and second coils, eliminating the need for separate electromagnet systems for each direction. This multi-functionality reduces the overall power consumption compared to using multiple independent electromagnets, as the shared magnetic core and integrated structure reduce redundant energy expenditure.
3Measurement precision
If multiple electromagnets are used to drive microrobot, then microrobot control capability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple electromagnet systems into a single integrated electromagnet with first and second coils wound in different directions around a common magnetic core. This consolidation reduces device complexity by eliminating redundant structural elements, connection points, and control interfaces that would exist if multiple separate electromagnets were used, while maintaining comprehensive microrobot control capability.
4Reliability
If conventional electromagnetic field driving device is used, then microrobot can be driven, but compatibility with medical equipment is poor
Solution Approach 1:
The integrated electromagnet design with its compact structure improves compatibility with medical equipment by reducing the overall device footprint. The ability to control microrobot movement in multiple directions from a single electromagnet location allows for better integration with existing medical imaging and treatment equipment without requiring large dedicated spaces or complex arrangements of multiple electromagnets.
