Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional systems require drivers to manually control media asset playback in vehicles, leading to potential distractions and dangerous driving situations, as they need to manage playback while driving.

Innovation Solution

A system that automatically controls media asset playback in vehicles based on the vehicle's motion state, pausing playback when the vehicle is in motion and resuming it when it is stationary, and optionally presenting alternate content during motion to minimize driver distraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the driver manually controls media asset playback, then the user can fully control media consumption, but the driver may be distracted and dangerous driving situations may arise

Engineering Contradiction:

Improvemedia playback controlVSAvoiddriver distraction

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system enables self-service automation by having the media playback system automatically detect vehicle motion state through sensors and control playback without driver intervention. The system serves itself by using vehicle state data to autonomously pause or resume media, eliminating the need for manual driver control while maintaining appropriate media consumption behavior.

Inventive Principle:

Principle #25Self-service

2Object-affected harmful factors

If the system automatically pauses media playback when the vehicle is moving, then driver distraction is reduced, but the media consumption experience is interrupted

Engineering Contradiction:

Improvedriver distractionVSAvoidmedia consumption continuity

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system performs preliminary actions by automatically pausing media playback in advance when vehicle motion is detected, preventing driver distraction before it occurs. The system proactively monitors vehicle state and preemptively controls media playback, ensuring safety is prioritized while maintaining the ability to resume consumption when appropriate.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies dynamics by making media playback state adaptive to vehicle motion conditions. Playback automatically transitions between paused and playing states based on real-time vehicle motion detection, creating a dynamic system that responds to changing environmental conditions rather than maintaining a fixed playback state.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If the system determines vehicle motion state continuously, then playback control accuracy is improved, but energy consumption increases

Engineering Contradiction:

Improvemotion state detectionVSAvoidsystem energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system implements periodic action by checking vehicle motion state at regular intervals rather than continuously monitoring without interruption. This periodic detection approach maintains sufficient accuracy for determining when to pause or resume playback while reducing overall energy consumption compared to truly continuous monitoring.

Inventive Principle:

Principle #19Periodic action

AI summary

Systems and methods for method for automatically controlling playback of a media asset in a vehicle are provided. A presentation of a media asset to a user in the vehicle is generated. A motion state of the vehicle is determined. In response to determining that the motion state indicates that the vehicle is moving, the presentation of the media asset is paused. In response to determining that the motion state indicates that the vehicle is not moving, the presentation of the media asset is resumed.
