Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need to prevent unauthorized changes to media service preferences on a media playback system during social gatherings or events, where guests may alter the owner's preferred settings, and to revert to the original preferences once the event is over.

Innovation Solution

A media playback system is designed to detect triggers that suspend and resume playback preference tracking, allowing temporary suspension of media service preferences and restoring them to a predefined state based on detecting specific triggers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If playback preference tracking is continuously enabled to maintain personalized music services, then user customization and personalization are improved, but the risk of unauthorized changes during social gatherings increases

Engineering Contradiction:

Improvemusic service preference customizationVSAvoidunauthorized preference changes

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by detecting triggers that suspend playback preference tracking before unauthorized changes can occur. The media playback system proactively monitors for suspension triggers and automatically suspends preference tracking when detected, preventing guests from altering the owner's preferred settings during social gatherings.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism - the trigger detection system - that mediates between continuous preference tracking and unauthorized changes. This intermediary layer allows the system to dynamically switch between tracking and non-tracking states based on detected triggers, protecting preferences during social events while maintaining customization during normal operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If playback preference tracking is suspended during events to prevent changes, then preference protection is improved, but the ability to adapt to new music selections during the event is reduced

Engineering Contradiction:

Improvepreference setting stabilityVSAvoidreal-time music selection adaptation

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system applies dynamics by making the playback preference tracking state changeable rather than fixed. The media playback system dynamically transitions between tracking and non-tracking states based on detected triggers, allowing it to adapt its behavior to different operational contexts - protecting preferences during social gatherings while maintaining flexibility for normal use.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements periodic action through the suspension and resumption of playback preference tracking. The system periodically switches between tracking and non-tracking states based on trigger detection, creating a rhythm of protection and adaptation that maintains both stability and flexibility at appropriate times.

Inventive Principle:

Principle #19Periodic action

3Ease of operation

If the system automatically suspends and resumes playback preference tracking based on triggers, then user control during social gatherings is improved, but system complexity increases

Engineering Contradiction:

Improveautomatic preference managementVSAvoidtrigger detection and state management

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The media playback system performs self-service by automatically detecting triggers and managing the suspension/resumption of playback preference tracking without requiring manual user intervention. The system monitors its own state, detects relevant triggers, and autonomously adjusts preference tracking accordingly, simplifying operation for the user despite the underlying complexity.

Inventive Principle:

Principle #25Self-service

AI summary

An example computing device is configured to transmit playback preference tracking information to a media service registered with a media playback system and, after transmitting the playback preference information, (a) determine a first time boundary corresponding to a beginning of a zone scene that causes a first playback device in a first zone of the media playback system to be configured for synchronous playback of media with a second playback device in a second zone of the media playback system, (b) determine a second time boundary corresponding to an end of the zone scene, and (c) transmit, to the media service registered with the media playback system, a request to remove playback preference tracking information received between the first time boundary and the second time boundary.
