Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite-based GPS positioning is used, then positioning can be achieved in outdoor environments, but positioning accuracy deteriorates due to weather and terrain interference
Solution Approach 1:
The patent introduces a magnetic field as an intermediary medium for positioning. Instead of relying on satellite signals that penetrate through atmosphere and terrain, the system uses a local magnetic field generated by a scanning unit to create positioning references. The magnetic sensing unit detects this local field, providing a reliable positioning mechanism that works independently of satellite signal quality.
Solution Approach 2:
The patent replaces the electromagnetic satellite-based positioning system with a magnetic field-based positioning system. By using magnetic field generation and detection mechanisms, the system achieves positioning without relying on satellite electromagnetic signals, thereby eliminating the accuracy problems associated with weather and terrain interference.
2Adaptability or versatility
If mobile communication network positioning is used, then positioning can be achieved in covered areas, but positioning accuracy deteriorates due to base station limitations
Solution Approach 1:
The magnetic positioning system is designed to be universally applicable across different environments. The scanning unit generates magnetic fields that can be detected anywhere within the detection space, making the system adaptable to various locations including indoor areas, tunnels, and other covered environments where traditional mobile network positioning fails.
Solution Approach 2:
The patent employs two rotating magnetic surfaces that create a three-dimensional detection space. By using rotational motion in multiple dimensions, the system establishes magnetic field references throughout a volumetric space, enabling accurate positioning in three-dimensional space rather than being limited to two-dimensional surface positioning.
3Ease of operation
If cell phone positioning systems are used, then positioning functionality is available, but positioning accuracy deteriorates in indoor or signal-blocked locations
Solution Approach 1:
The magnetic positioning system is self-contained and does not require external infrastructure like satellites or base stations. The scanning unit generates its own magnetic field references, and the sensing unit detects these self-generated references to determine position. This self-service capability enables the system to operate autonomously in any location without relying on external signal sources.

AI summary
A magnetic positioning device includes a magnetic scanning unit and a magnetic sensing unit. The magnetic scanning unit is for forming a first magnetic surface and a second magnetic surface. The first magnetic surface and second magnetic surface rotatably form a detection space. The magnetic sensing unit is disposed in the detection space for recording a first time point and a second time point. The magnetic sensing unit is in contact to the first magnetic surface at the first time point and defines a first-angle data. The magnetic sensing unit is in contact to the second magnetic surface at the second time point and defines a second-angle data. The first-angle data and the second-angle data define a location data of the magnetic sensing unit in the detection space with respect to the magnetic scanning unit, wherein the first time point is not the same as the second time point.
