Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of capsule endoscope is performed without professional training, then operation simplicity is improved, but operation safety and scanning completeness deteriorate
Solution Approach 1:
The capsule endoscope system performs self-navigation and self-positioning using its own magnetic moving member and magnetic field generation capabilities. The system automatically determines its position, orientation, and movement trajectory without requiring external professional operation, enabling untrained users to safely operate the device while maintaining scanning completeness through autonomous control.
Solution Approach 2:
The system dynamically adjusts magnetic field parameters (strength, direction, and spatial distribution) based on real-time position detection and pre-stored safety operating ranges. By automatically modifying these parameters within predefined safe zones, the system ensures operation safety while maintaining ease of use for untrained operators.
2Ease of operation
If manual operation of capsule endoscope is performed without professional training, then operation simplicity is improved, but scanning completeness deteriorates
Solution Approach 1:
Before operation begins, the system pre-stores safe operating ranges and corresponding magnetic field parameters for various body types and examination parts. These pre-configured parameters ensure that when the capsule endoscope operates autonomously, it automatically covers all necessary scanning areas without requiring professional guidance, thus maintaining scanning completeness while simplifying operation.
Solution Approach 2:
The system continuously monitors its own position, orientation, and movement through magnetic field detection, providing real-time feedback to automatically adjust navigation commands. This closed-loop control ensures the capsule endoscope remains within safe operating ranges and completes comprehensive scanning of the target area, preventing information loss while requiring no professional intervention.
3Adaptability or versatility
If magnetic moving member moves beyond safe operating range, then movement freedom is improved, but operation safety deteriorates
Solution Approach 1:
The system pre-defines safe operating ranges for the magnetic moving member based on anatomical boundaries and safety constraints. Before the capsule endoscope can move beyond these safe zones, the magnetic field generation and navigation systems automatically generate counteracting forces to prevent such movement, thereby ensuring operation safety while allowing freedom of movement within the predefined safe boundaries.
Solution Approach 2:
The magnetic field acts as an intermediary between the control system and the capsule endoscope. By using magnetic field interactions, the system enables smooth movement within safe ranges while automatically preventing movement beyond boundaries through magnetic field constraints, thus mediating between movement freedom and operational safety without requiring direct mechanical confinement.
