Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic field is applied to rotate the capsule endoscope about a horizontal axis to submerge it into the liquid, then the capsule endoscope can overcome surface tension, but the power source load increases
Solution Approach 1:
The magnetic field generating device dynamically adjusts the magnetic field strength and direction based on the capsule endoscope's position and operational needs. The system transitions between different magnetic field modes (rotating field for submersion, linear field for navigation) to optimize energy consumption while maintaining operational effectiveness.
Solution Approach 2:
The system changes magnetic field parameters (strength, direction, rotation speed) to achieve capsule endoscope submersion with minimal energy consumption. By optimizing these parameters, the system overcomes surface tension while keeping power source load within acceptable limits.
2Adaptability or versatility
If a rotating magnetic field is applied to pivot the capsule endoscope, then the capsule endoscope can navigate obstacles in the alimentary canal, but the magnetic control becomes less stable
Solution Approach 1:
The magnetic field generating device dynamically adjusts the magnetic field configuration based on real-time capsule endoscope position and orientation. The system uses feedback control to maintain stable magnetic guidance while enabling the capsule endoscope to pivot and navigate around obstacles in the alimentary canal.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor capsule endoscope response to magnetic fields and adjusts the field generation accordingly. This ensures stable magnetic control while maintaining the ability to navigate complex geometries and overcome obstacles.
3Ease of operation
If the capsule endoscope remains on the liquid surface, then it can be easily controlled, but it cannot effectively navigate through the alimentary canal
Solution Approach 1:
The system dynamically transitions the capsule endoscope from surface-level control to submerged navigation by applying appropriate magnetic fields. The control unit adjusts magnetic field parameters to enable the capsule endoscope to submerge and navigate through the alimentary canal while maintaining operational effectiveness.
Solution Approach 2:
The magnetic field generating device creates three-dimensional magnetic field patterns that enable the capsule endoscope to transition from two-dimensional surface movement to three-dimensional submerged navigation. This dimensional transition allows the capsule endoscope to effectively navigate through the alimentary canal while maintaining control.

AI summary
A guiding system includes a capsule medical device including a permanent magnet; a magnetic field generating unit to generate a magnetic field to the magnet to guide the capsule, and change a direction of the magnetic field in a three-dimensional space; and a control unit to control the magnetic field generated by the generating unit. Where the capsule is located on a liquid surface, the control unit generates a first magnetic field such that a plane, which is parallel to a vertical axis and in which a magnetic field including a rotating magnetic field where a magnetic field is rotated on the plane is generated, pivots about the vertical axis at a predetermined period and a second magnetic field for generating a magnetic attracting force for moving the magnet vertically downward to submerge the capsule in the liquid, the first and second magnetic fields being applied at a same time.
