Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems for audio and data sharing among devices are limited in allowing full stereo experience sharing, are restricted by transmission range, and lack the ability to transmit and receive metadata such as ID3 tags, making it difficult for recipients to identify and purchase shared audio files.

Innovation Solution

A system and method for wireless stereo communication that allows seamless capture and transmission of audio-file identification data, enabling users to share and rebroadcast audio signals with associated metadata, and facilitating the creation of audio sharing networks using built-in transmitters/receivers or intermediary devices, allowing selective transmission and reception of audio and playlist information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless headphones are used to share music from a media device, then users can listen wirelessly, but users cannot be too far from the source due to transmission range limits

Engineering Contradiction:

Improvewireless listening convenienceVSAvoidtransmission range

Core Design Contradiction:

Ease of operationVSLength of moving object

Solution Approach 1:

The patent introduces a wireless transmitter as an intermediary device that receives audio signals from the media device and retransmits them to wireless headphones. This intermediary extends the effective transmission range by creating a relay system, allowing users to listen wirelessly at greater distances from the original media device while maintaining connection through the intermediate transmitter.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If Bluetooth transmission is used for wireless audio, then audio can be transmitted wirelessly, but anyone with reception capability can receive the data

Engineering Contradiction:

Improvewireless audio transmissionVSAvoiddata security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements different transmission modes with varying security characteristics. In dedicated transmission mode, the system establishes a point-to-point connection between specific devices, providing secure and reliable audio transfer. This localized quality approach ensures that sensitive audio data is transmitted only to authorized recipients rather than being broadcast to all nearby devices, thus maintaining both wireless convenience and data security.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If wired headphones are shared between users, then music can be shared, but the third party cannot experience full stereo sound

Engineering Contradiction:

Improvemusic sharing capabilityVSAvoidstereo audio quality

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates independent copies of the audio signal transmission path by using wireless transmitters that receive the full stereo audio output from the media device and transmit it wirelessly to wireless headphones. Each user receives a complete stereo signal copy rather than sharing a single wired connection, preserving full stereo audio quality for each listener while enabling music sharing between multiple users.

Inventive Principle:

Principle #26Copying

4Adaptability or versatility

If media files are transferred between storage mediums to share music, then users can share audio files, but third party intellectual property rights are infringed

Engineering Contradiction:

Improvemusic sharing functionalityVSAvoidintellectual property infringement

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical file transfer system (copying media files between storage mediums) with a wireless audio transmission system. Instead of transferring copyrighted audio files that could infringe intellectual property rights, the system transmits real-time audio signals wirelessly from the media device to headphones. This substitution allows music sharing functionality while avoiding copyright infringement by not creating or distributing digital copies of protected content.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system and method are disclosed for capturing information associated with wireless audio sounds among a plurality of users. When a user encounters audio sound files of interest, the user can capture information regarding the audio sounds, such as title, artist, collection, genre, year, encoding rate, size, playlist, a unique identifier, or other desired information. The information can be used to seamlessly purchase the sound files from a remote digital repository.
