Solution Overview

Problem

The increasing number of broadcast sources in public places makes it difficult for users to securely choose a desired broadcast source, leading to power drain and cumbersome connection processes for audio devices like earbuds and headsets, especially when encryption is involved.

Innovation Solution

Proximity-based broadcast onboarding using an onboarding device that facilitates seamless connection by detecting audio devices near it, providing a one-click synchronization to desired broadcast sources, and managing encryption keys without storing pairing information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual scanning and pairing management is used for broadcast sources, then connection security can be maintained, but user operation becomes cumbersome and power consumption increases

Engineering Contradiction:

Improveconnection securityVSAvoiduser operation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces an onboarding device as an intermediary between the audio device and broadcast sources. The onboarding device receives broadcast information including encryption keys, stores them securely, and provides them to the audio device during onboarding. This mediator approach maintains security while eliminating manual scanning and pairing operations, as the onboarding device automatically manages the connection process.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The onboarding device performs preliminary actions by pre-receiving and storing broadcast information and encryption keys before the audio device needs to connect. This advance preparation eliminates the need for real-time scanning and pairing operations, reducing both user effort and power consumption while maintaining secure connections.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If audio devices scan multiple broadcast sources to find desired sources, then connection options increase, but power consumption increases

Engineering Contradiction:

Improvebroadcast source selectionVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The onboarding device serves as an intermediary that maintains a database of broadcast sources and their information. Instead of the audio device scanning multiple sources, the onboarding device provides the necessary broadcast information and encryption keys directly to the audio device, enabling connection without extensive scanning and significantly reducing power consumption.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Broadcast source information is pre-collected and stored in the onboarding device before the audio device needs to connect. This preliminary action eliminates the need for the audio device to scan and search for broadcast sources in real-time, reducing power consumption while maintaining the ability to connect to multiple broadcast sources.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If encryption keys are managed through traditional pairing methods, then security is maintained, but the onboarding process becomes complex and time-consuming

Engineering Contradiction:

Improveencryption securityVSAvoidonboarding time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The onboarding device acts as a secure intermediary that receives, stores, and distributes encryption keys. During onboarding, the audio device simply needs to connect to the onboarding device, which automatically provides the necessary encryption keys for the desired broadcast source. This eliminates complex manual pairing processes while maintaining security, significantly reducing onboarding time.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Encryption keys are pre-obtained and stored in the onboarding device before the audio device needs to connect to broadcast sources. This preliminary preparation of security credentials allows for rapid onboarding without time-consuming manual pairing or key exchange processes, while maintaining strong encryption security.

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed are systems and techniques for wireless communications. For example, an audio device can receive, from an onboarding device associated with a broadcast device, one or more connection request signals requesting a connection with the audio device and comprising an address of the onboarding device. The audio device can output, for transmission to the onboarding device based on the address of the onboarding device, one or more first connection signals to establish a first connection with the onboarding device. The audio device can receive, from the onboarding device via the first connection with the onboarding device, one or more information signals comprising synchronization information associated with the broadcast device. The audio device can synchronize with the broadcast device using the synchronization information to receive one or more broadcast signals comprising broadcast information.
