Solution Overview

Problem

Existing networked media playback systems require manual setup of network configuration parameters each time a playback device moves between different wireless local area networks (WLANs), which is inconvenient and time-consuming.

Innovation Solution

Playback devices are equipped with the ability to store and propagate network configuration parameters for multiple WLANs, allowing seamless connectivity by automatically sharing these parameters among devices within the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If playback devices manually configure network parameters each time they move between WLANs, then network connectivity is established, but setup time and user effort increase significantly

Engineering Contradiction:

Improvenetwork connectivityVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system pre-configures multiple network profiles including SSIDs, passwords, and connection parameters before the device needs to switch networks. When moving between WLANs, the device simply selects from pre-configured profiles rather than manually re-entering all network parameters, thus establishing connectivity quickly without time-consuming setup operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system copies network configuration parameters from one WLAN profile to another. When a device connects to a new network, it can replicate successful configuration patterns from existing profiles, adapting them to the new network context. This eliminates the need to manually reconfigure each network connection from scratch, significantly reducing setup time while maintaining reliable connectivity.

Inventive Principle:

Principle #26Copying

2Reliability

If playback devices manually configure network parameters each time they move between WLANs, then network connectivity is established, but user convenience deteriorates

Engineering Contradiction:

Improvenetwork connectivityVSAvoidsetup convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs automatic network configuration without requiring user intervention. The playback device autonomously selects appropriate WLAN profiles, enters credentials, and establishes connections based on pre-configured parameters. This self-service capability eliminates manual setup operations entirely, greatly improving ease of operation while ensuring reliable network connectivity through systematic profile management.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Users perform network configuration setup in advance when first setting up the system or encountering network issues. These pre-configured profiles then handle subsequent network transitions automatically. This preliminary action shifts the complexity from repeated user operations to a one-time or rare setup event, dramatically improving ongoing ease of operation while maintaining connectivity reliability.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If playback devices support multiple WLAN connections, then adaptability improves, but device complexity increases

Engineering Contradiction:

ImproveWLAN compatibilityVSAvoidconfiguration management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments network configuration into discrete, manageable profiles, each containing specific WLAN parameters (SSID, password, network type). Instead of handling all network configurations as a single complex entity, the device divides them into independent units that can be selectively activated. This segmentation reduces the perceived complexity of managing multiple WLAN connections while maintaining high adaptability to different network environments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements a universal network profile structure that can accommodate multiple WLAN types and configurations through a standardized framework. Each profile uses the same data structure and configuration interface regardless of the specific network, allowing the device to handle diverse WLANs (home, office, guest networks) with unified management. This multi-functionality approach enables broad adaptability without proportionally increasing operational complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A playback device includes programming for connecting to a first wireless local area network (WLAN) and storing a first set of network configuration parameters including an identifier of the first WLAN and a first security parameter for the first WLAN. The functions also include disconnecting from the first WLAN, receiving a second set of network configuration parameters including an identifier of a second WLAN and a second security parameter for the second WLAN, and storing the second set of network configuration parameters. The functions also include reconnecting to the first WLAN using the stored first set of network configuration parameters and, after reconnecting to the first WLAN, transmitting, absent user request, the second set of network configuration parameters to at least one other playback device that is connected to the first WLAN for storage on the at least one other playback device that is connected to the first WLAN.
