Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Bluetooth devices can only transmit audio data to one device at a time, limiting the ability to share audio data with multiple devices simultaneously, which is a common requirement in various scenarios.

Innovation Solution

An electronic device establishes Bluetooth low-energy connections with multiple Bluetooth devices and sets them to belong to the same group locally in response to an audio sharing command, allowing simultaneous audio data transmission to all devices within the group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Bluetooth devices transmit audio data to one device at a time, then the transmission protocol remains simple and stable, but the ability to share audio data with multiple devices simultaneously is limited

Engineering Contradiction:

Improveaudio sharing capabilityVSAvoidconnection management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the multiple Bluetooth devices into distinct groups, where each group can be independently managed. The electronic device establishes separate Bluetooth connections for different device groups, allowing audio data to be transmitted to multiple groups simultaneously while maintaining independent control over each group's connection parameters and audio stream

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a group management mechanism as an intermediary layer between the audio data source and individual Bluetooth devices. This intermediary manages the mapping between audio streams and device groups, handling the complexity of multi-device transmission without requiring changes to the underlying Bluetooth transmission protocol

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple Bluetooth devices are connected simultaneously for audio sharing, then audio data can be shared with multiple devices, but the connection management and group setting complexity increases

Engineering Contradiction:

Improveaudio sharing efficiencyVSAvoidgroup configuration ease

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent performs preliminary grouping of Bluetooth devices before audio transmission begins. Devices are pre-configured into groups with assigned identifiers, and the electronic device stores this group information in advance. When audio sharing is initiated, the pre-established group structure enables immediate multi-device transmission without requiring complex real-time configuration

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamic group management that allows groups to be created, modified, and dissolved based on real-time needs. The system can dynamically add or remove devices from groups, adjust group identifiers, and reconfigure audio stream routing without interrupting ongoing transmissions, providing operational flexibility while maintaining simplicity

Inventive Principle:

Principle #15Dynamics
