Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a capsule medical device is introduced into the body to capture and transmit images, then diagnostic capability is improved, but positioning precision deteriorates due to lack of magnetic field control
Solution Approach 1:
The system uses a magnetic field detector to detect the position of the capsule medical device in real-time and feeds this information back to the control unit. The control unit then adjusts the magnetic field generating unit to precisely control the capsule's movement and positioning, creating a closed-loop control system that improves positioning precision.
Solution Approach 2:
The patent replaces mechanical positioning mechanisms with a magnetic field-based control system. Instead of using physical motors or actuators inside the body, the system uses external magnetic fields to control the capsule's movement, eliminating complex mechanical components while achieving precise positioning.
2Manufacturing precision
If magnetic field conditions are not optimized, then device complexity is reduced, but image capture quality deteriorates due to inefficient navigation
Solution Approach 1:
The system dynamically adjusts the magnetic field conditions based on the capsule's real-time position and the desired target location. The control unit modifies magnetic field parameters such as strength and direction to optimize navigation at different stages, ensuring high image capture quality while adapting to changing conditions.
Solution Approach 2:
The patent changes magnetic field parameters including field strength, direction, and distribution patterns to optimize the capsule's navigation and positioning. By adjusting these parameters dynamically, the system achieves precise image capture without requiring overly complex device architecture.
3Measurement precision
If precise magnetic field control is implemented, then positioning precision is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic magnetic field pulses rather than continuous fields to control the capsule's movement. The magnetic field is activated only when needed for positioning adjustments, reducing overall energy consumption while maintaining precise positioning capability through intermittent control actions.
Solution Approach 2:
The capsule medical device incorporates a magnet that interacts with the external magnetic field to achieve self-propulsion and positioning. The device uses its own magnetic properties in conjunction with the control system's magnetic fields, reducing the need for additional energy-intensive actuators or motors within the capsule itself.
