Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mechanical fixing using housing shape or magnets is used to position coils, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical positioning systems (housing shapes, magnets) with an electromagnetic field-based measurement system. The receiver coil arrangement detects magnetic field components from the conductor loop arrangement, and the evaluation device calculates position information based on phase relationships, eliminating the need for mechanical fixing structures.
Solution Approach 2:
The patent introduces magnetic field components as an intermediary between the conductor loop arrangement and the receiver coil arrangement. By detecting the magnetic field components along linearly independent directions and analyzing their phase relationships, the system achieves precise positioning without direct mechanical contact or complex mechanical structures.
2Measurement precision
If coil arrays are used for positioning, then positioning accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent segments the measurement task into three independent magnetic field component detections along linearly independent directions. Each component provides partial position information, and the evaluation device combines these segments to determine the complete position, simplifying the overall operation while maintaining high accuracy.
Solution Approach 2:
The receiver coil arrangement is designed to detect magnetic field components in multiple directions simultaneously, making it a multi-functional device that can determine position information without requiring separate measurement systems for each direction, thus improving ease of operation.
3Adaptability or versatility
If movable coils are used with guidance to optimal position, then positioning adaptability is improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical guidance systems with an electromagnetic field-based measurement and evaluation system. The system can determine the position of mobile coils by detecting magnetic field components and calculating phase relationships, providing adaptability without mechanical guidance structures.
Solution Approach 2:
The evaluation device automatically calculates position information from the detected magnetic field components without requiring external guidance or intervention. The system serves itself by using the electromagnetic field interactions to determine and communicate position data, reducing the need for additional positioning mechanisms.
4Adaptability or versatility
If special coil geometries are used to widen field profile, then positioning tolerance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent replaces complex coil geometry designs with a measurement-based approach. By detecting magnetic field components along linearly independent directions and analyzing phase relationships, the system achieves positioning tolerance through calculation rather than relying on specially designed coil geometries, reducing manufacturing precision requirements.
