Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If massive and complicated positioning calculations are performed to achieve angular positioning in both horizontal and vertical directions, then positioning capability is improved, but positioning errors increase
Solution Approach 1:
The positioning device is divided into a base assembly and a connecting assembly, each with its own geomagnetic sensor. The base assembly sensor provides absolute orientation reference, while the connecting assembly sensor measures relative deviation. This segmentation allows the system to obtain both horizontal and vertical angular information without requiring complex calculations, thereby maintaining positioning accuracy while achieving comprehensive angular positioning capability.
2Device complexity
If deviation angle measurement is performed using a single geomagnetic sensor, then device structure is simplified, but angular positioning in both horizontal and vertical directions cannot be achieved
Solution Approach 1:
The connecting assembly acts as an intermediary between the base assembly and the target object. It contains a geomagnetic sensor that measures the deviation angle relative to the base assembly, while the base assembly provides the absolute geomagnetic reference. This intermediary structure enables the system to achieve three-dimensional angular positioning by combining relative and absolute measurements without requiring an overly complex single-sensor design.
3Productivity
If relative angle calculation is performed between two geomagnetic components, then computing requirements are reduced, but calculation accuracy may be affected
Solution Approach 1:
The control component continuously obtains deviation angle information from the connecting assembly's geomagnetic sensor and uses this feedback to calculate and adjust the relative angle between the base assembly and connecting assembly. The system also incorporates absolute angle data from the base assembly's geomagnetic sensor, creating a feedback mechanism that ensures calculation accuracy while maintaining computational efficiency through real-time angle correction.

AI summary
The present disclosure provides a geomagnetic positioning device, comprising a base assembly and a connecting assembly. The base assembly comprises a control component, a driving component, and a first geomagnetic component. The control component is electrically connected with the driving component and the first geomagnetic component. The connecting assembly is disposed at the driving component and comprises a second geomagnetic component. Wherein the control component obtains the deviation angle of the second geomagnetic component relative to the first geomagnetic component. The control component controls the driving component according to the deviation angle to adjust the relative angle of the connecting assembly relative to the base assembly. Through the reading difference to geomagnetism between the first geomagnetic component and the second geomagnetic component, the relative angle between the control base assembly and the connecting assembly and the absolute angle of the two can be calculated for precise control.
