Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth-based beacons or Wi-Fi routers are deployed as anchor points for indoor positioning, then positioning service coverage is improved, but investment costs and system complexity increase significantly
Solution Approach 1:
The patent enables ordinary mobile terminals to automatically serve as beacon terminals for indoor positioning without requiring specialized infrastructure deployment. Users simply need to install the positioning application on their mobile devices, and the system automatically identifies and utilizes these devices as anchor points, eliminating the need for manual beacon deployment and maintenance.
Solution Approach 2:
The patent transforms ordinary mobile terminals into multi-functional devices that can simultaneously perform their original communication functions and serve as positioning anchor points. This universal approach allows any mobile device to contribute to the positioning infrastructure, reducing the need for dedicated positioning hardware.
2Measurement precision
If Bluetooth-based beacons or Wi-Fi routers are deployed as anchor points, then positioning accuracy is improved, but maintenance costs and operational burden increase
Solution Approach 1:
The system automatically manages the lifecycle of beacon terminals by utilizing existing mobile terminals. The application automatically identifies suitable devices, configures them as beacons, and manages their operation without requiring manual intervention for deployment, configuration, or maintenance updates.
Solution Approach 2:
The patent implements a dynamic beacon terminal selection mechanism where the system can automatically identify and switch between different mobile terminals serving as anchor points based on their availability and performance. This dynamic approach ensures continuous positioning service without manual reconfiguration.
3Reliability
If a large number of beacons and routers are deployed, then positioning service reliability is improved, but initial investment and operational costs increase
Solution Approach 1:
Instead of deploying physical beacon hardware throughout the environment, the patent creates virtual copies of beacon functionality within ordinary mobile terminals. Each user's mobile device becomes a source of positioning information, effectively copying the beacon function across numerous devices without requiring physical infrastructure multiplication.
Solution Approach 2:
The system leverages the existing mobile terminals that users already possess and carry, eliminating the need for separate beacon device deployment. These self-owned devices automatically contribute to the positioning infrastructure, reducing the quantity of additional hardware needed.

AI summary
Disclosed are indoor positioning methods, apparatuses, electronic device and computer readable storage medium. The indoor positioning method includes: obtaining state data of a mobile terminal; based on a pre-trained position classification model, determining a position classification of the mobile terminal according to the state data of the mobile terminal; when the position classification of the mobile terminal is an anchor point position, taking the mobile terminal as a beacon terminal and sending an anchor point position broadcast instruction to the beacon terminal to enable the beacon terminal to broadcast the anchor point position. In the technical solution, a mobile terminal meeting anchor point requirements is taken as a beacon terminal to provide convenient positioning services, so as to avoid deployment and maintenance of a large number of beacons, hardware of routers, and related mapping relationship, thus greatly reducing investment costs and facilitating promotion of use.
