Solution Overview

Problem

Existing messaging systems do not facilitate the streaming of audio content from one user's device to another user's device, particularly when the recipient is listening via an external audio output device, which limits user engagement and interaction.

Innovation Solution

A messaging system that allows users to stream audio from one device to another by detecting when a user is using an external audio output device, providing a user-selectable button for streaming, saving the audio as a file, and adding a link to the message thread for later access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If audio streaming functionality is added to messaging systems, then user engagement and interaction are enhanced, but device complexity and system requirements increase

Engineering Contradiction:
Improveaudio streaming capabilityVSAvoidmessaging system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines audio streaming functionality with the existing messaging system by integrating audio capture, streaming control, and playback features into the messaging application interface. This merging allows users to stream audio during message exchanges without requiring separate dedicated audio streaming devices or systems, thereby enhancing versatility while managing device complexity through integration.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If audio streaming is enabled when external audio output devices are connected, then audio sharing capability is improved, but control and management complexity increases

Engineering Contradiction:
Improveaudio output flexibilityVSAvoidaudio streaming control
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects when an external audio output device is connected and enables the audio streaming button accordingly. This self-service mechanism eliminates the need for manual configuration or complex user settings, as the system autonomously manages audio output routing based on device connection status, thereby improving ease of operation while maintaining audio output flexibility.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If audio files are saved and linked in message threads, then user interaction is enhanced, but data storage and management requirements increase

Engineering Contradiction:
Improveaudio sharing functionalityVSAvoiddata storage requirement
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system creates and stores audio files locally on user devices and generates shareable links that reference these stored files. Rather than transmitting or duplicating audio data across the network with each message, the system maintains local copies and shares access through links, thereby enhancing audio sharing functionality while minimizing network data transmission and centralized storage requirements.

Inventive Principle:
Principle #26Copying
