Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is used to locate shared resources, then the positioning system is simple and easy to implement, but the positioning accuracy is insufficient leading to mapping errors
Solution Approach 1:
The patent combines GPS positioning with Bluetooth positioning to form a hybrid positioning system. GPS provides coarse positioning while Bluetooth base stations provide fine-grained positioning correction, achieving high accuracy without excessive complexity. The system merges two different positioning technologies to overcome the limitations of using either alone.
Solution Approach 2:
Bluetooth base stations serve as intermediary elements between the GPS satellite system and the shared resource. They establish a local positioning reference framework that mediates and corrects GPS positioning errors in the specific area, acting as an intermediate layer that improves accuracy without requiring direct satellite visibility.
2Measurement precision
If Bluetooth positioning with multiple base stations is used, then positioning accuracy is improved, but the system complexity and infrastructure requirements increase
Solution Approach 1:
The system deploys Bluetooth base stations only in specific areas where shared resources are located, rather than covering entire cities. This partial deployment achieves the necessary positioning accuracy for the target application while avoiding the excessive infrastructure complexity of city-wide coverage.
Solution Approach 2:
Bluetooth base stations are pre-deployed and configured in areas where shared resources will be located before the actual positioning need arises. The fingerprint database is pre-built with positioning information, so when a user needs to locate a shared resource, the system can immediately provide accurate positioning without real-time complex calculations.
3Productivity
If traditional map positioning is used, then the system is easy to operate, but users cannot rapidly and accurately find shared resources
Solution Approach 1:
The patent replaces traditional map-based visual searching with an automated positioning system that uses Bluetooth signals and fingerprint matching. Instead of manually searching through maps, the system automatically calculates and provides the precise location of shared resources, substituting mechanical map reading with electronic signal processing and algorithmic position determination.

AI summary
The present disclosure relates to a positioning method and device. First Global Positioning System (GPS) positioning data of terminal equipment and second GPS positioning data of a region where a shared resource is located are acquired (S101). It is then judged (S102) whether a distance between the terminal equipment and the region where the shared resource is located is in a specific range or not according to the first GPS positioning data and the second GPS positioning data, wherein when the distance between the terminal equipment and the region where the shared resource is located is in the specific range, a position of the shared resource is determined (S103) based on Bluetooth data corresponding to the shared resource. The terminal equipment is controlled (S104) to present position information of the shared resource.
