Solution Overview

Problem

Existing wireless audio systems face difficulties in self-configuration, particularly when replacing a wireless speaker subsystem, as they often require pre-configured matching units, or necessitate end-user configuration without automatic assistance.

Innovation Solution

A method and system for configuring wireless multi-speaker audio systems, involving discovery of subsystems, defining a virtual device, synchronizing internal clocks, identifying a leader device, and providing a system control interface to implement operational changes across the subsystems, allowing for autonomous formation and control of a unified audio system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pre-configuration approach is used, then ease of operation is improved, but device complexity and loss of time increase

Engineering Contradiction:
Improveease of operationVSAvoidloss of time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The wireless speaker subsystems perform automatic self-configuration by discovering each other on the wireless network, defining a virtual device, synchronizing clocks, and electing a leader device without requiring pre-configured matching units or manual user setup. This eliminates the need for pre-purchase configuration while avoiding time loss through automated initialization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions during the boot-up or initialization phase of wireless speaker subsystems, where they automatically discover each other, establish network relationships, and configure themselves before being put into service. This preliminary self-configuration eliminates the need for manual setup while maintaining operational simplicity.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If pre-configuration approach is used, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of requiring complex pre-configuration processes during manufacturing, the system enables wireless speaker subsystems to self-configure automatically upon connection to the wireless network. Each subsystem autonomously discovers other subsystems, establishes the virtual device representation, synchronizes internal clocks, and elects a leader device, thereby maintaining operational simplicity while reducing configuration complexity.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If end-user configuration is used, then adaptability is improved, but ease of operation worsens

Engineering Contradiction:
ImproveadaptabilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides adaptability by allowing any number of wireless speaker subsystems to be automatically integrated into a unified audio system through self-discovery and self-configuration. Users simply need to connect subsystems to the wireless network, and the system automatically defines virtual devices, synchronizes clocks, and establishes control relationships, eliminating the need for manual configuration while maintaining full adaptability.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If automatic self-configuration is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The self-configuration process is segmented into distinct phases: wireless network connection, subsystem discovery, virtual device definition, clock synchronization, and leader device election. Each phase is handled by dedicated functionality within the subsystems, making the complex automated configuration process manageable and systematic while maintaining operational simplicity for end users.

Inventive Principle:
Principle #1Segmentation

AI summary

Described herein are various methods and systems relating to the unification of media devices, and more specifically to the provision of wireless audio systems. In overview, two or more wireless speaker subsystem units substantially autonomously form a single wireless audio system having its own control interface. This control interface is used to apply operational changes across the wireless audio system, such as volume adjustment. That is, an operational change may be applied to the system as a whole, and this change is subsequently implemented by each of the individual wireless speaker subsystem units.
