Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a magnetic antenna uses a simple plate-like magnetic core with a coil, then the structure is simple and easy to manufacture, but the communication distance is limited and cannot achieve long-distance communication
Solution Approach 1:
The magnetic core is divided into multiple plate-like magnetic body parts (first magnetic body part, second magnetic body part, etc.) that are connected at angles to each other. Each part has a coil wound around it, creating segmented magnetic coupling units that collectively extend the communication range while maintaining manufacturing simplicity.
Solution Approach 2:
The patent transitions from a single-plane magnetic core structure to a three-dimensional arrangement by connecting plate-like magnetic body parts at angles (e.g., 90 degrees). This spatial extension in multiple dimensions enhances magnetic field distribution and extends communication distance without complicating the basic plate-like structure.
2Reliability
If a magnetic antenna uses a bent or folded magnetic core structure, then the magnetic coupling is improved, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
Instead of bending a single continuous magnetic core, the patent segments it into separate plate-like magnetic body parts that are connected at angles. This segmentation maintains manufacturing simplicity while achieving the magnetic coupling enhancement that bending would provide, as each segment can be independently manufactured and assembled.
Solution Approach 2:
The patent achieves improved magnetic coupling by extending the structure into multiple dimensions through angular connections between plate-like parts, rather than bending within a single plane. This dimensional approach improves coupling efficiency without the complexity of bent structures.
3Reliability
If a resonant type antenna is used, then the communication distance can be extended, but the antenna cannot be used for magnetic coupling communication effectively
Solution Approach 1:
The patent creates a magnetic coupling antenna structure that achieves long-distance communication capability typically associated with resonant antennas. By using multiple plate-like magnetic body parts connected at angles with coils wound around each part, the system provides both magnetic coupling functionality and extended communication range, making it versatile for different communication modes.
