Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face inconvenience in distinguishing between spam and useful phone calls, especially when driving or unable to answer calls, as existing methods require manual determination and may result in missed information.

Innovation Solution

A vehicle system that includes a communication device capable of recognizing voice calls, generating voice recognition results, and using a dialogue manager to determine call content relevance and necessity, providing information only when a predetermined score is met, and terminating calls when appropriate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user manually determines whether each phone call is spam or useful, then the user can make informed decisions about each call, but this requires significant time and attention especially when driving

Engineering Contradiction:

Improvecall discrimination accuracyVSAvoidtime for manual call evaluation

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary voice recognition and content analysis of incoming calls before the user needs to decide whether to answer. The dialogue manager pre-evaluates call relevance and generates recommendations, so when the user receives the call notification, the decision-making work has already been done in advance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system serves itself by automatically analyzing call contents through voice recognition, determining relevance to user information, and generating recommendations without requiring user intervention. The dialogue manager autonomously evaluates each call and provides ready-made recommendations for the user

Inventive Principle:

Principle #25Self-service

2Loss of information

If the user answers every phone call to ensure important information is not missed, then no useful information is lost, but the user experiences increased distraction and safety risks when driving

Engineering Contradiction:

Improveuseful call informationVSAvoiddriving safety risk

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The dialogue manager acts as an intermediary between the incoming call and the user. It analyzes the call content, compares it with user information, determines relevance, and presents a recommended answer to the user. This intermediary layer filters out spam calls before they reach the user, reducing the need for the user to manually evaluate each call while driving

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces the mechanical process of manual call evaluation with automated voice recognition and AI-based dialogue management. Instead of the user listening to and evaluating each call manually, the system uses technology to perform the evaluation and present recommendations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If the system provides all phone call contents to the user, then the user receives complete information, but the user is overwhelmed by irrelevant spam call information

Engineering Contradiction:

Improvecall information completenessVSAvoidinformation processing complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts only the relevant and useful information from phone calls by comparing call contents with user information stored in the system. The dialogue manager identifies and extracts meaningful calls while filtering out spam, presenting only the essential information to the user rather than all raw call data

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If the system uses automated voice recognition and dialogue management to filter calls, then the user experience is improved by reducing manual evaluation, but the system complexity increases

Engineering Contradiction:

Improvecall filtering convenienceVSAvoidsystem structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The dialogue manager is designed as a universal system that handles multiple functions: voice recognition, call content analysis, relevance determination, recommendation generation, and call filtering. This multi-functional approach consolidates what could be multiple separate systems into a single integrated solution

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A vehicle includes a communication device configured to communicate with a user terminal. The vehicle further includes an input processor configured to recognize a voice of a telephone call received by the user terminal and generate a voice recognition result on the voice of the telephone call. The vehicle also includes a dialogue manager configured to determine telephone call contents based on the voice recognition result and determine whether or not to provide the telephone call contents to a user based on the telephone call contents.
