Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current body-insertable apparatus systems for imaging inside a subject, such as capsule endoscopes, face challenges in precisely controlling the position and posture of the capsule endoscope within the gastrointestinal tract for comprehensive imaging, particularly in navigating complex anatomical structures and ensuring efficient data acquisition.
Innovation Solution
A housing apparatus with multiple housing units for permanent magnets, binding units, detectors, and a control unit that selectively binds or releases the magnets based on detection results, allowing for precise control of the capsule endoscope's position and posture using a magnetic field, guided by a position indication sheet and a magnetic field generating apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a permanent magnet is used to guide the capsule endoscope, then the system configuration is simplified, but the precision of position and posture control is insufficient for comprehensive imaging
Solution Approach 1:
The single permanent magnet is divided into multiple permanent magnets arranged in an array. Each magnet can be independently controlled to bind or release from the capsule endoscope, enabling precise positional control and comprehensive imaging of different gastrointestinal regions while maintaining a relatively simple overall system structure.
2Measurement precision
If multiple permanent magnets with different magnetisms are prepared, then the guidance precision is improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The housing apparatus employs dynamic control of multiple permanent magnets, where each magnet can be selectively bound or released based on real-time detection of the capsule endoscope's position. This dynamic adjustment enables precise guidance without requiring all magnets to be permanently fixed, reducing overall device complexity while maintaining high guidance precision.
Solution Approach 2:
A detection unit continuously monitors the position of the capsule endoscope, and this detection information feeds back to the control unit, which adjusts the binding state of individual permanent magnets accordingly. This closed-loop feedback system achieves precise guidance while automating the control process, reducing operation difficulty despite the presence of multiple magnets.
3Device complexity
If manual operation is used to guide the capsule endoscope, then the system is simple, but the speed and accuracy of data acquisition are reduced
Solution Approach 1:
The housing apparatus enables self-service operation through automated control. The detection unit automatically tracks the capsule endoscope position, and the control unit autonomously adjusts the permanent magnet binding states to guide the capsule, eliminating the need for manual operation while significantly improving data acquisition speed and efficiency.
Solution Approach 2:
Manual mechanical guidance is replaced with an automated magnetic field control system. The control unit uses detection information to automatically adjust the magnetic field configuration, substituting human operation with an automated electromechanical system that achieves faster and more accurate data acquisition while maintaining reasonable system complexity.
