Positioning Device Position Information Sharing via Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning devices cannot share position information with each other, limiting their ability to learn about the positions and paths of other devices.
Innovation Solution
A method and system for position information sharing, where a positioning device or server sends and receives position queries and information, allowing devices to display and share position data within groups or through a server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a positioning device uses traditional GPS and inertial navigation technology, then it can determine its own position and movement path, but it cannot share position information with other positioning devices
Solution Approach 1:
The patent introduces a positioning server as an intermediary that collects position information from multiple positioning devices and distributes it to requesting devices. This mediator approach enables position information sharing without requiring direct peer-to-peer communication between all devices, thus solving the information isolation problem while managing complexity through centralized coordination.
Solution Approach 2:
The positioning device is enhanced with multi-functional capabilities including not only self-positioning but also position information acquisition, sharing, and display functions for other devices. This universal approach allows the same device to perform multiple roles: as a positioning entity, an information requester, and an information provider, eliminating the need for separate dedicated communication systems.
2Loss of information
If a positioning device acquires position information of other devices through a positioning server, then position information sharing is enabled, but communication cost and network dependency increase
Solution Approach 1:
The positioning server performs preliminary actions by pre-collecting and storing position information from multiple positioning devices before any specific query occurs. This advance preparation enables rapid information retrieval and distribution when needed, reducing the communication overhead and energy consumption during actual position queries compared to real-time direct device-to-device communication.
Solution Approach 2:
Instead of establishing direct real-time connections between positioning devices for information exchange, the system creates copies of position information through the server. The server maintains copies of position data from multiple devices and distributes these copies to requesting devices, eliminating the need for multiple direct communication channels and reducing overall network energy consumption.
3Loss of information
If a positioning device displays position information of multiple devices, then position information sharing is comprehensive, but information processing and display complexity increases
Solution Approach 1:
The patent segments position information by associating it with specific positioning device identifiers and organizing it through positioning groups. This segmentation allows the display device to process and show position information in an organized manner, managing complexity through structured data organization rather than handling all position data as a single undifferentiated set.
Solution Approach 2:
The positioning server acts as an intermediary that performs the complex task of collecting, organizing, and managing position information from multiple devices. By offloading this information processing complexity to the server, individual positioning devices can display comprehensive position information without bearing the full burden of information processing complexity themselves.

AI summary
Embodiments of the present invention provide a position information sharing method and a positioning device and system. The position information sharing method includes sending a position query request to a first positioning device or a positioning server. The position query request carries a first positioning device identifier. Position information of the first positioning device is received. The position information is sent by the first positioning device or the positioning server according to the position query request. The position information of the first positioning device can be displayed.
