Inaudible Frequency Group Connection for User Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting multiple electronic devices are inefficient, especially in noisy and crowded environments, and struggle to quickly establish connections between hundreds or thousands of devices.
Innovation Solution
A method that uses an inaudible frequency range to transmit connection request signals between user terminals, allowing them to form groups and provide synchronized content, including audio, video, and images, with a server managing the connection service based on position and time information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional pairing methods (Bluetooth, request-approval messages) are used to connect electronic devices, then connection can be established between devices, but the connection process becomes extremely slow when hundreds or thousands of devices need to be connected
Solution Approach 1:
The patent applies preliminary action by having devices automatically discover and pre-establish connection relationships before actual content sharing is needed. The system performs connection setup in advance through automatic discovery mechanisms, so when hundreds or thousands of devices need to connect, the connection infrastructure is already in place, eliminating the time-consuming one-by-one pairing process.
2Reliability
If request-approval messages are transmitted for device connection, then connection can be established with user consent, but the process fails in noisy and crowded places where message transmission is difficult
Solution Approach 1:
The patent replaces the mechanical/message-based connection request system with an acoustic signal-based system. Instead of relying on text messages or visual notifications that can be obscured by noise, the system uses audible acoustic signals that can penetrate and be detected in noisy environments. This substitution allows connection requests to be reliably transmitted and recognized even in crowded places with high ambient noise levels.
3Ease of operation
If manual pairing is used for device connection, then connection can be established between devices, but the process requires user intervention and becomes cumbersome when connecting large numbers of devices
Solution Approach 1:
The patent implements self-service by enabling devices to automatically discover each other and establish connections without user intervention. The system uses automatic discovery mechanisms where devices independently identify potential connection targets and initiate connection protocols autonomously. This eliminates the need for manual pairing operations, making the process extremely efficient when connecting large numbers of devices while maintaining ease of operation.

AI summary
A connection service providing method includes outputting, by a first user terminal from among a plurality of user terminals, a connection request signal to at least one second user terminal among the plurality of user terminals through an inaudible frequency range based on a trigger signal for initiating a connection between the plurality of user terminals; and connecting the at least one second user terminal and the first user terminal as a group; and providing a connection service associated with the group on the first user terminal.
