Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single coil is used for wireless communication, then the device structure is simple, but the reliability of data transmission is degraded due to misalignment or distance between transmitting and receiving coils
Solution Approach 1:
The transmitting coil is divided into multiple separate coils (first coil, second coil, third coil) with different winding angles. Each coil segment contributes to forming a magnetic field with multiple directivities, improving reliability by ensuring at least one coil maintains effective magnetic coupling regardless of receiving coil orientation or position.
Solution Approach 2:
The coils are designed with different winding angles (first winding angle, second winding angle, third winding angle) relative to the magnetic body's axial direction. This asymmetric configuration creates a magnetic field with multiple directivities, allowing the system to maintain reliable communication across various alignment conditions between transmitting and receiving coils.
2Adaptability or versatility
If multiple coils with different winding angles are used, then the recognition range and magnetic coupling are improved, but the device complexity increases
Solution Approach 1:
The multiple coils with different winding angles collectively provide universal adaptability to various receiving coil positions and orientations. Each coil configuration serves the function of maintaining magnetic coupling under different alignment conditions, making the transmitting device universally compatible with receiving coils regardless of their specific orientation or distance.
Solution Approach 2:
The solution extends the magnetic field coverage by adding angular dimensionality through coils wound at different angles. Instead of a single-axis magnetic field, the system creates a three-dimensional magnetic field distribution with multiple directivities, expanding the recognition range in spatial dimensions.
3Reliability
If coils are wound at different angles, then magnetic coupling is enhanced for varying positions, but the manufacturing precision requirements increase
Solution Approach 1:
Each coil is designed with a specific local quality characteristic (different winding angles) optimized for particular spatial directions. The first coil, second coil, and third coil each have winding angles tailored to create magnetic field components in different directions, ensuring that regardless of receiving coil orientation, at least one coil provides effective magnetic coupling.
Solution Approach 2:
The system changes the winding angle parameter of the coils relative to the magnetic body's axial direction. By varying this geometric parameter across multiple coils, the system creates a magnetic field with multiple directivities, enhancing magnetic coupling reliability without requiring precise alignment mechanisms.
