Solution Overview

Problem

Existing in-vehicle audio systems lack seamless integration with internet-based audio services, requiring external smart devices and manual search methods, leading to a diminished user experience.

Innovation Solution

A vehicle entertainment system that integrates voice command-based audio playlist generation, allowing users to add audio content to third-party services like Spotify directly from the vehicle, using metadata extraction and translation to create playlists without external devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If external smart devices and manual search methods are used for audio content selection, then device compatibility and content variety are improved, but ease of operation and user experience deteriorate

Engineering Contradiction:

Improvecontent varietyVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The vehicle entertainment system performs automatic audio content identification and playlist generation without requiring user interaction with external devices. The system extracts metadata from playing audio, identifies content automatically, and creates playlists independently, eliminating manual search operations while maintaining content variety.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations (physical device connections, button presses, menu navigation) with automated digital processing. The system uses metadata extraction algorithms, audio recognition, and automated playlist generation to substitute for manual content selection processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If Car Play or Gracenote APIs are used for audio streaming, then integration with existing systems is improved, but functionality and audio processing capabilities are limited

Engineering Contradiction:

Improvesystem integrationVSAvoidaudio processing capability

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The vehicle entertainment system implements universal functionality by integrating multiple audio sources (terrestrial radio, internet streaming, local files) and third-party services (Spotify, Pandora) within a single unified system. The system performs diverse functions including audio streaming, metadata extraction, content identification, and automated playlist generation without requiring separate external devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a metadata extraction service as an intermediary layer between audio content sources and the user interface. This intermediary automatically processes audio metadata, identifies content characteristics, and enables intelligent playlist generation, bridging the gap between raw audio streams and user-friendly functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If hands-free voice control is implemented for playlist management, then ease of operation is improved, but system complexity increases

Engineering Contradiction:

Improveease of operationVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical interfaces (touchscreens, physical buttons, multiple controls) with voice-activated commands. Users interact through natural speech patterns, and the system processes audio inputs to execute playlist operations, simplifying the user interface while managing the underlying complexity through automated processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The voice control system automatically processes user commands and executes playlist operations without requiring manual confirmation or complex interaction sequences. The system self-manages the complexity of command parsing, metadata extraction, and playlist generation, presenting only simple voice-based control to the user.

Inventive Principle:

Principle #25Self-service

AI summary

Systems and methods for generating a playlist of audio content for a vehicle are disclosed. An audio input is received at a vehicle entertainment system of the vehicle while an audio content item is currently played by the vehicle entertainment system. The audio input includes an audio command trigger and an audio playlist command. In response to detecting the audio command trigger in the audio input, the audio input is parsed to determine the audio playlist command. A metadata associated with the audio content item is determined. In response to determining the audio playlist command, the audio content item is caused to be added to an audio content playlist of a third-party service based on the metadata of the audio content item.
