Solution Overview

Problem

Electronic devices face challenges in providing appropriate responses to ambiguous or purposeless user inputs during chatting modes, leading to difficulties in continuous interaction and inaccurate intent recognition.

Innovation Solution

An electronic device system that includes a user interface, processor, and memory, which stores a main database and an auxiliary database. The system extracts information from user inputs, identifies matched data, categorizes inputs, and provides responses from the auxiliary database when main database matches are not identified, ensuring appropriate responses are given.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device uses a conventional speech recognition service to process user inputs, then it can provide services based on recognized user voices, but it cannot provide appropriate responses to ambiguous or purposeless user inputs, leading to ambiguous or terminating responses

Engineering Contradiction:

Improveresponse accuracyVSAvoidhandling of ambiguous inputs

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the database into a main database and an auxiliary database. The main database stores structured input data with corresponding response data for clear, recognizable inputs. The auxiliary database stores category information for ambiguous or unrecognizable inputs. This segmentation allows the system to handle different types of inputs appropriately, resolving the contradiction between response accuracy for clear inputs and adaptability for ambiguous inputs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces category information as an intermediary element between the main database and the auxiliary database. When the speech recognition service cannot recognize a user input, the system uses category information from the auxiliary database to determine appropriate response data. This intermediary mechanism enables the system to handle ambiguous inputs adaptively while maintaining reliability for recognized inputs.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Duration of action of moving object

If the electronic device provides responses for unrecognizable user inputs, then continuous interaction can be maintained, but the responses may not accurately correspond to the user input intent

Engineering Contradiction:

Improvecontinuous interactionVSAvoidintent recognition accuracy

Core Design Contradiction:

Duration of action of moving objectVSMeasurement precision

Solution Approach 1:

The patent segments the response generation process into two paths: one for recognized inputs (main database) and one for unrecognizable inputs (auxiliary database with category information). This segmentation allows the system to maintain continuous interaction through the auxiliary path while preserving intent recognition accuracy through the main path, resolving the contradiction between duration of interaction and measurement precision.

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If the electronic device uses only a main database with structured input data, then response data can be accurately matched for recognized inputs, but the system lacks the capability to handle ambiguous or purposeless utterances

Engineering Contradiction:

Improveinput matching accuracyVSAvoidhandling of purposeless utterance

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent segments the database system into a main database for structured, recognizable inputs and an auxiliary database for ambiguous or purposeless utterances. The main database ensures high matching accuracy for clear inputs, while the auxiliary database provides category-based responses for unrecognizable inputs, resolving the contradiction between measurement precision and adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent makes the database system multi-functional by enabling it to handle both structured recognizable inputs (through the main database) and ambiguous unrecognizable inputs (through the auxiliary database with category information). This universality allows the system to maintain high accuracy for clear inputs while also being adaptable to purposeless utterances.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

According to an embodiment, an electronic device includes a user interface, a memory, and a processor. The memory is configured to store a main database including at least one input data or an auxiliary database including at least one category including pieces of response data. The processor is configured to receive a user input, using the user interface, and extract first information from the user input. The processor is also configured to identify whether a portion of the input data of the main database matches the first information. The processor is further configured to identify a category of the user input in response to identifying that the input data of the main database does not match the first information. Additionally, the processor is configured to identify the auxiliary database corresponding to the category, and provide first response data based on an event that the auxiliary database is identified.
