Solution Overview

Problem

Existing media playback systems require manual configuration and connection of new playback devices to secure networks, which can be cumbersome and inconvenient for users.

Innovation Solution

A method for automatically connecting and configuring new playback devices to secure networks, where the devices send a join message upon powering up and receive security parameters and configuration data from a server or existing devices within the network, allowing them to join and synchronize with other devices without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual configuration and connection of new playback devices to secure networks is used, then network security is maintained, but user convenience and setup simplicity deteriorate

Engineering Contradiction:
ImproveUser convenience in device setupVSAvoidManual configuration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The new playback device automatically performs network discovery, authentication, and configuration by sending join messages and receiving security parameters without user intervention. The device self-configures by obtaining security parameters from existing network devices and automatically establishing secure connections.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Existing playback devices in the network are pre-configured with security parameters and are prepared to authenticate new devices. The system pre-establishes the security framework and authentication mechanisms before new devices join, enabling automatic enrollment.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If automatic connection and configuration is implemented, then ease of operation improves, but network security risks increase

Engineering Contradiction:
ImproveAutomatic device enrollmentVSAvoidNetwork security integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Existing playback devices in the network act as intermediaries that verify and transmit security parameters to new devices. The controller device mediates the authentication process by receiving join messages, determining security parameters, and facilitating secure connection establishment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where new devices send join messages indicating availability to join, existing devices respond with authentication decisions and security parameters, and the connection status is continuously monitored and adjusted to maintain security.

Inventive Principle:
Principle #23Feedback

3Productivity

If manual configuration steps are required, then security control is maintained, but setup time and user effort increase

Engineering Contradiction:
ImproveDevice setup speedVSAvoidUser time for configuration
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The device automatically performs network discovery, authentication, and configuration by sending join messages and receiving security parameters without user intervention. The device self-configures by obtaining security parameters from existing network devices and automatically establishing secure connections.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Existing playback devices in the network are pre-configured with security parameters and are prepared to authenticate new devices. The system pre-establishes the security framework and authentication mechanisms before new devices join, enabling automatic enrollment.

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments are provided for causing a playback device to be automatically added to a secure network for rendering media in synchrony with other devices in the secure network. The playback device may, without any input from a user, transmit a first message indicating that the playback device is available to join the network. Upon receiving the first message, a device already in the secure network may transmit to the playback device a second message indicating security parameters for joining the network. The playback device may then join the secure network accordingly. Embodiments are also provided for causing a playback device to be automatically configured, without any input from a user. Another device in the secure network may receive a configuration table indicating setup information for the playback device, and may subsequently transmit the setup information to the playback device and cause the playback device to be configured accordingly.
