Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise positioning requests are frequently made to obtain accurate location information, then positioning accuracy is improved, but network resource consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing positioning deviation information for reference positioning points before actual positioning requests are made. This allows the system to use rough positioning location information combined with pre-computed deviation data to derive precise positioning results, eliminating the need for frequent high-cost precise positioning requests while maintaining accuracy.
Solution Approach 2:
The system introduces an intermediary approach by using reference positioning points with known precise locations and pre-computed deviation information as mediators. Instead of directly requesting precise positioning for every service equipment location, the system uses these reference points as intermediaries to calculate and correct rough positioning results, thereby reducing network resource consumption while maintaining positioning accuracy.
2Measurement precision
If high-accuracy positioning equipment is used to ensure precise location information, then positioning accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system creates a virtual copy of the positioning function by using software-based correction algorithms instead of hardware-based high-precision equipment. The rough positioning location information is copied and then corrected using pre-computed deviation data from reference positioning points, achieving precise positioning results without requiring complex or expensive positioning hardware.
Solution Approach 2:
The system replaces the mechanical/hardware positioning system with a software-based correction system. Instead of using complex high-precision positioning equipment, the invention uses algorithmic correction based on rough positioning data and pre-computed deviation information, substituting hardware complexity with software intelligence to achieve the same positioning accuracy.

AI summary
The present disclosure provides a positioning method and device, an electronic device, and a storage medium. The positioning method may include obtaining a precise positioning request sent by a service equipment. The precise positioning request may carry rough positioning location information of the service equipment. The positioning method may further include determining, based on the rough positioning location information of the service equipment, a reference positioning point corresponding to the service equipment, and obtaining precise positioning location information of the service equipment by correcting, based on positioning deviation information of the reference positioning point, the rough positioning location information of the service equipment. The positioning deviation information of the reference positioning point may be calculated based on precise positioning location information of the reference positioning point and rough positioning location information of the reference positioning point.
