Solution Overview

Problem

Existing systems for providing services in vehicles, such as making calls or changing destinations, are inconvenient due to the need for manual input while driving, leading to potential errors and increased risk.

Innovation Solution

A service providing system that includes a display device and a mobile device connected via various communication methods, allowing for keyword extraction from voice conversations to display additional information, such as contact details or navigation options, without requiring manual input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual input is used for making calls or changing destinations while driving, then the user can control the vehicle functions, but the risk of errors and accidents increases due to distraction

Engineering Contradiction:

Improveconvenience of making calls and changing destinationsVSAvoidsafety while driving

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces manual mechanical input (typing phone numbers, selecting menu options) with voice-based acoustic input. The voice recognition system captures spoken commands, converts them to text, and executes the corresponding actions, allowing drivers to operate communication and navigation functions without taking their hands off the wheel or eyes off the road for extended periods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system automatically processes voice inputs by extracting keywords, searching for matching information (phone numbers, destinations), and presenting results for confirmation. This automated workflow reduces the cognitive load and manual steps required compared to traditional manual input methods.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If voice recognition is used to extract keywords from conversations, then the ease of operation improves by avoiding manual input, but the measurement precision of keyword extraction may be insufficient

Engineering Contradiction:

Improveautomatic service provision without manual inputVSAvoidaccuracy of keyword extraction from voice

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces an intermediary processing layer between voice input and service execution. The voice recognition system converts speech to text, a keyword extraction algorithm identifies relevant terms, and a result presentation interface allows the user to confirm or correct the extracted keywords before service execution. This multi-stage intermediary process improves overall accuracy despite individual stage limitations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system provides feedback to the user by displaying the extracted keywords and search results for confirmation. This feedback loop allows users to verify the accuracy of automatic keyword extraction and correct errors if needed, improving the reliability of the voice-controlled service provision.

Inventive Principle:

Principle #23Feedback

AI summary

A display device provided to a vehicle includes a communication unit which communicates with a mobile device, a control unit which acquires a keyword in a call conversation if the mobile device makes a call, and a display unit which displays additional information corresponding to the keyword. Accordingly, the display device can provide the user with services corresponding to keywords of the call conversation with convenience.
