Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical tracking cameras with barcode targets are used, then positioning accuracy is improved, but the system requires constant illumination and is sensitive to dirt and abrasion
Solution Approach 1:
The patent replaces the optical tracking system with a magnetic field-based localization system. Instead of using optical cameras and barcode targets that require illumination and are sensitive to dirt, the invention uses ground transceivers with magnetic antennas that generate magnetic fields for position detection, eliminating the harmful effects of dirt and abrasion on optical components
Solution Approach 2:
The patent changes the physical parameter basis from optical reflection to magnetic field induction. By using magnetic fields instead of light reflection, the system achieves positioning accuracy without being affected by illumination conditions or surface contamination
2Ease of operation
If RF-ID transmitters with large antennas are used, then ease of operation is improved, but localization precision deteriorates
Solution Approach 1:
The patent changes the antenna type from large RF-ID antennas to small magnetic induction antennas. By using magnetic field induction with compact antennas, the system achieves both ease of operation and high localization precision, resolving the trade-off between antenna size and positioning accuracy
3Reliability
If ground transceivers with external power supply are used, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-powered ground transceivers that harvest energy from the movement of the movable device through magnetic induction. The ground transceivers generate their own operating energy from the relative motion, eliminating the need for external power supplies and reducing system complexity while maintaining reliability
