Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing question answering systems risk suggesting dangerous operations to customers when mechanically generating answers from original materials, leading to potential harm if customers follow incorrect instructions.

Innovation Solution

A question answering system is designed with a question-answer pair generation processing unit and a replacement processing unit that identifies and replaces answer sentences suggesting dangerous operations, using a dangerous operation determination unit and an answer sentence replacement unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If answer sentences are mechanically generated from original materials, then productivity of question-answer pair generation is improved, but reliability of answer safety deteriorates

Engineering Contradiction:

Improvequestion-answer pair generation efficiencyVSAvoidanswer safety

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary classification of answer sentences into safe and dangerous categories before providing answers to customers. The classification unit analyzes each generated answer sentence in advance to determine its safety level, preventing dangerous operations from being suggested to customers while maintaining efficient mechanical generation of question-answer pairs.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If many expected questions and answer sentences are prepared, then coverage of customer inquiries is improved, but loss of time in preparation increases

Engineering Contradiction:

Improveinquiry coverageVSAvoidpreparation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system automatically generates expected questions and answer sentences from existing product information and manuals without requiring manual preparation. The question-answer pair generation unit extracts and formulates question-answer pairs autonomously, significantly reducing preparation time while expanding the coverage of customer inquiries that can be addressed.

Inventive Principle:

Principle #25Self-service

3Loss of information

If dangerous operations are included in original materials, then completeness of information is improved, but object-affected harmful factors increase

Engineering Contradiction:

Improveinformation completenessVSAvoidcustomer harm from dangerous operations

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system applies different quality standards to different parts of the answer generation process. While maintaining complete information from original materials for internal reference, it specifically filters and classifies answer sentences to identify and exclude dangerous operations from customer-facing responses, allowing local optimization of safety without sacrificing overall information completeness.

Inventive Principle:

Principle #3Local quality

AI summary

A question answering system includes a dangerous operation determination unit configured to determine whether question-answer pair data includes a dangerous operation, and an answer sentence replacement unit configured to replace, when it is determined that the dangerous operation is included, an answer sentence including a description of the dangerous operation included in a document by a replaced answer sentence depending on a classification of the dangerous operation, to thereby create replaced question-answer pair data.
