Wearable Device Registration via SDP Request and Server Lookup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in understanding and utilizing Bluetooth devices due to varied functions and the need for manual research or specific applications, making it inconvenient to pair and use Bluetooth devices effectively.
Innovation Solution
A wearable device registration system that broadcasts a Session Description Protocol (SDP) request message to search for surrounding Bluetooth devices, receives access information, and downloads detailed device information from a server using URL information, allowing easy access to device functions and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth devices have varied functions and profiles, then device functionality and versatility are improved, but user understanding and ease of operation deteriorate
Solution Approach 1:
The patent introduces an intermediary system (server with database) that mediates between diverse Bluetooth devices and users. When a device is discovered, the system automatically retrieves and presents standardized functional information from the server, translating varied device profiles into comprehensible user-friendly descriptions without requiring users to understand underlying Bluetooth protocol differences
2Loss of information
If detailed device information is provided through manual research or dedicated applications, then user understanding is improved, but convenience and ease of operation deteriorate
Solution Approach 1:
The system implements self-service by automatically retrieving, processing, and presenting device information without requiring user action to search for or download applications. The discovery device autonomously queries the server using device identifiers and retrieves comprehensive functional information, which is then automatically presented to the user in an accessible format
Solution Approach 2:
An intermediary server system acts as a bridge between Bluetooth devices and users, centralizing device information storage and retrieval. This mediator handles all information requests automatically, eliminating the need for users to manually research device functions through multiple sources or dedicated applications
3Adaptability or versatility
If Bluetooth devices require pairing and dedicated applications for use, then device functionality is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent extracts the complexity of device information management from the user's direct interaction with Bluetooth devices. By separating information retrieval and interpretation functions into a dedicated server system, the complexity of understanding varied device profiles, required applications, and pairing procedures is removed from the user experience while preserving full device functionality
Data Source
AI summary
Disclosed is a system and method for searching and registering a wearable Bluetooth device in a surrounding area. The searching Bluetooth device broadcasts a session description protocol (SDP) request message by executing the SDP. When the SDP request message broadcast by the searching Bluetooth device is received, a surrounding Bluetooth device executes the SDP, generates an SDP response message, and transmits the SDP response message to the searching Bluetooth device. When the SDP response message is received, the searching Bluetooth device requests that the server provide the detailed information file of the surrounding Bluetooth device, based on server access information included in the SDP response message. When the detailed information file of the surrounding Bluetooth device is received from the server, the searching Bluetooth device stores the detailed information file.
