Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing call filtering technologies are ineffective in determining the purpose of incoming calls from unknown numbers without direct user interaction, as they require pre-stored database information and cannot filter calls in real-time effectively.

Innovation Solution

An electronic apparatus using an AI model to conduct a telephone conversation with the caller, determine the purpose of the call, and provide a summary to the user, allowing them to decide whether to accept the call without direct user involvement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a database comparison method is used to filter incoming calls, then calls from known malicious numbers can be blocked, but calls from new unknown numbers cannot be filtered

Engineering Contradiction:

Improvecall filtering accuracyVSAvoidability to handle new unknown numbers

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary voice conversation analysis before the user answers the call. The voice assistant conducts a preliminary interaction with the caller to determine call purpose, allowing the system to filter malicious calls before they reach the user, while also being adaptable to new numbers without requiring pre-existing database entries

Inventive Principle:

Principle #10Preliminary action

2Reliability

If real-time conversation analysis is performed during a call, then malicious calls can be detected, but the user must make a direct call which consumes time

Engineering Contradiction:

Improvemalicious call detectionVSAvoidcall time consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The voice assistant conducts the preliminary conversation analysis before the user answers, performing all necessary malicious call detection activities in advance. This eliminates the need for the user to engage in time-consuming direct calls, as the system has already determined whether to block the call before it connects to the user

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If manual recording of call purposes is required, then database information can be updated, but it requires direct communication and manual effort from users

Engineering Contradiction:

Improvecall purpose information storageVSAvoiduser effort to record information

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The voice assistant automatically performs the information gathering and recording functions that previously required manual user effort. During the preliminary conversation, the voice assistant autonomously determines the call purpose and updates the database without requiring the user to directly communicate with the caller or manually record information

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The voice assistant acts as an intermediary between the user and the caller, handling all communication and information gathering tasks. It conducts the conversation, analyzes the call purpose, and updates the database on behalf of the user, eliminating the need for direct user-caller communication

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An electronic apparatus is provided. The electronic apparatus includes a communicator, and a processor to, in response to a call request received through the communicator, perform a first telephone conversation with a counterpart making the call request through a voice assistant using an artificial intelligence (AI) model which is learned to generate contents of telephone conversations, and provide a user interface for second telephone conversation between a user of the electronic apparatus and the counterpart based on contents of the first telephone conversation.
