Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In-vehicle entertainment systems are limited by the availability, quality, and geographical relevance of locally broadcast radio signals, leading to inconsistent and inferior listening experiences due to signal strength, interference, and lack of relevant content during travel.

Innovation Solution

A system that receives and processes multiple broadcast streams, separates them into segments based on content types and geographical areas, and selectively provides the highest-quality, relevant content over a network, creating a unique playlist that enhances the listening experience without user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the vehicle's entertainment system manually tunes to local broadcast sources, then the system can receive broadcast content, but the content availability is limited by broadcast range and signal strength

Engineering Contradiction:

Improvecontent availabilityVSAvoidsignal strength limitation

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The system segments broadcast content into distinct types (music, news, traffic, weather) and geographically tags them, allowing selective assembly of content segments from multiple sources to create optimized playlists that overcome local signal limitations

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A central server acts as an intermediary between multiple broadcast sources and the vehicle's entertainment system, collecting, processing, and redistributing content segments over a network to eliminate direct dependency on local broadcast signal strength

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If the vehicle's entertainment system waits for broadcast announcements, then the system can receive traffic and weather information, but the information frequency is insufficient for continuous travel needs

Engineering Contradiction:

Improveinformation completenessVSAvoidwaiting time for announcements

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system pre-records and stores broadcast content segments at a central server before they are needed, organizing them by content type and geographical location so that relevant information can be immediately retrieved and played without waiting for live announcements

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates continuous playlists that seamlessly connect content segments from multiple broadcast sources, ensuring uninterrupted delivery of traffic and weather information throughout the vehicle's travel path without gaps or waiting periods

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If the vehicle's entertainment system uses local broadcast sources, then the system can provide content, but the quality is reduced by interference and signal loss

Engineering Contradiction:

Improvebroadcast qualityVSAvoidinterference and signal loss

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system merges multiple broadcast segments covering the same content (e.g., multiple recordings of the same song or news segment) and selects the highest quality version, combining advantages from different sources to overcome individual signal quality limitations

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system evaluates and compares quality parameters (signal strength, clarity, absence of interference) of different broadcast segments and dynamically selects segments with optimal parameters, changing the quality characteristic by choosing superior alternatives

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If the vehicle's entertainment system manually searches for stations, then the system can find relevant content, but the operation complexity increases for the user

Engineering Contradiction:

Improvecontent selection flexibilityVSAvoiduser operation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically performs content selection, segmentation, and playlist generation based on the vehicle's location and travel path, eliminating the need for manual user intervention while maintaining high adaptability to different content preferences and geographical contexts

Inventive Principle:

Principle #25Self-service

AI summary

Methods and systems are employed for selectively controlling the presentation of broadcast content item in which a unique set of broadcast content items are presented based on the selection of a content type and a selection of a geography for each content type to control the manner in which broadcast content types are recorded and/or presented for the vehicle. In some embodiments, methods and systems are employed for providing relevant information to a vehicle based on receiving multiple broadcast streams, and separating the broadcast content items into segments based on a variety of content types along a predicted path of the vehicle.
