Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth anti-lost devices rely on periodic communication and signal intensity to determine distance, which is inefficient for finding devices lost outside the connected region, limiting their application scope and precision.
Innovation Solution
A method and apparatus that utilize a server to store and match location-based information from multiple terminals, allowing designated terminals to acquire and prompt on the location of devices via a database, even when they are outside the connected region, by establishing binding relationships and sharing location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth anti-lost devices rely on periodic communication and signal intensity to determine distance, then the device can be located within the connected region, but the application scope is limited and precision decreases for devices lost outside the connected region
Solution Approach 1:
The patent introduces a server as an intermediary between multiple terminals and the lost device. The server collects location information from multiple terminals and matches it with the lost device identifier, enabling location queries beyond the direct Bluetooth connection range. This mediator approach resolves the contradiction by extending adaptability while maintaining precision through centralized data processing.
Solution Approach 2:
The patent transitions from a single-terminal Bluetooth connection model to a multi-terminal location information database. By collecting location data from multiple terminals and storing it in a database with device identifiers, the system adds a dimensional layer of spatial information that can be queried regardless of current connection status, thus expanding application scope while preserving locating precision.
2Productivity
If the phone acquires signal intensity periodically to determine current distance, then the location can be determined within connected region, but the method is inefficient for finding devices outside the connected region
Solution Approach 1:
The patent implements preliminary action by having terminals proactively send their location information to the server in advance, and the server storing this information in a database before any loss occurs. When a device is lost, the location information is already available for immediate querying, dramatically improving productivity while expanding application scope to include devices outside the connected region.
Solution Approach 2:
The server acts as a mediator that collects, stores, and manages location information from multiple terminals. This intermediary system enables efficient location queries for devices outside the connected region by providing pre-collected location data, thus improving productivity without limiting adaptability.
3Measurement precision
If location information is stored in a centralized database from multiple terminals, then the application scope and precision are improved, but the device complexity increases
Solution Approach 1:
The patent extracts the complex functions of location data collection, storage, and matching from individual terminals and places them in a centralized server. This extraction reduces the complexity burden on each terminal device while maintaining high locating precision through the centralized database that aggregates location information from multiple sources.
Solution Approach 2:
The server is designed as a universal platform that handles location information from multiple different terminals and device types. By creating a multi-functional system that can process various location data formats and device identifiers, the patent achieves high precision locating while managing complexity through a standardized universal interface.

AI summary
The present disclosure provides a method and an apparatus for prompting according to location-based information, which belong to the field of communication technology. The method includes: acquiring by a server designated location-based information matching with a designated device identifier in a location-based information database at least storing location-based information reported by a plurality of terminals after receiving a location-based information acquiring request sent by a designated terminal; sending by the server the designated location-based information to the designated terminal, in which the designated terminal is configured to perform a prompt according to the designated location-based information. In the present disclosure, the designated terminal may acquire location-based information of the device positioned by other terminals via the server such that a user may find the device lost outside a connected region. Therefore, the method for prompting according to location-based information has a wide application scope and a high precision.
