Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing localisation technologies are used in complex mediums, then safety and accuracy are compromised, but the patent introduces magnetic field-based localisation to improve safety and measurement precision
Solution Approach 1:
The patent replaces mechanical/optical localisation systems with a magnetic field-based system. Magnetic field sensors detect magnetic field vectors generated by a magnetic source, enabling localisation without physical contact or line-of-sight requirements. This substitution improves safety in hazardous environments while maintaining measurement precision through mathematical processing of magnetic field data.
2Productivity
If existing localisation technologies operate in complex mediums, then speed and accuracy are limited, but the patent uses magnetic fields to enhance tracking speed and precision
Solution Approach 1:
The system performs preliminary actions by pre-calculating position based on magnetic field vector measurements and storing reference data. The magnetic source continuously generates fields and the system pre-processes sensor data to determine position, velocity, and acceleration. This preliminary processing enables rapid tracking without compromising accuracy, as the mathematical models are prepared in advance for quick computation.
3Measurement precision
If magnetic fields are generated in three dimensions at three different times, then localisation accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the localisation process into distinct measurement phases: measuring magnetic field vectors at different times (t1, t2, t3) and in different dimensions. Each measurement provides specific information about position and motion. This segmentation allows the system to achieve three-dimensional localisation accuracy while managing complexity through structured, time-separated measurements rather than simultaneous multi-dimensional sensing.
