Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a large columnar magnet is used to generate sufficient magnetic force for controlling the capsule endoscope, then the magnetic control effectiveness is improved, but the controller weight increases significantly
Solution Approach 1:
The patent applies the spheroidality principle by replacing the conventional columnar magnet shape with a spherical magnet shape. The spherical magnet with diameter D is designed to generate a magnetic field that provides sufficient magnetic force for controlling the capsule endoscope while minimizing the magnet's volume. The spherical geometry optimizes the magnetic field distribution in three-dimensional space, ensuring effective magnetic control without requiring the larger volume of a columnar magnet, thereby reducing the controller weight while maintaining adequate magnetic force.

AI summary
An endoscope system and a wireless controller are provided. The wireless controller includes a handle and a permanent magnet having a non-columnar shape. The handle has a grip portion and a controlling portion that is connected to the grip portion. The permanent magnet is assembled in the controlling portion. The permanent magnet is mirror-symmetrical across a largest area cross-section thereof. Cross-sections parallel to the largest area cross-section gradually decrease in cross sectional area from the largest area cross-section along two opposite directions perpendicular to the largest area cross-section. The permanent magnet of the wireless controller can generate a magnetic field to control a capsule endoscope located in a biological body from outside of the biological body.
