Solution Overview

Problem

Store employees face difficulties in efficiently collecting customer evaluations on product prices and incur costs by frequently visiting competing stores to monitor price changes, while existing systems require manual input of voice and image data for price negotiation and are limited to in-store use.

Innovation Solution

A price management system that extracts phrases related to price evaluations from customer voices using natural language processing and sends notifications when specific phrases are detected, allowing for automatic collection and analysis of price evaluations without the need for manual input or frequent store visits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If employees manually visit competing stores to monitor price changes, then price information can be obtained, but time consumption and operational costs increase

Engineering Contradiction:
Improveprice information acquisitionVSAvoidtime for store visits
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical action of employees physically visiting stores with an automated voice collection system using microphones and natural language processing technology. The system automatically captures customer voices, transcribes them, and extracts price evaluation information without human intervention, thereby eliminating time-consuming manual store visits while maintaining continuous price monitoring capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service price monitoring by automatically collecting, processing, and analyzing price evaluation data from customer voices without requiring employee involvement. The automated extraction and notification mechanisms allow the system to serve itself in gathering competitive pricing information continuously

Inventive Principle:
Principle #25Self-service

2Loss of information

If employees frequently visit competing stores to check price changes, then current pricing information is obtained, but operational costs increase

Engineering Contradiction:
Improvecurrent price informationVSAvoidoperational costs
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent replaces the costly manual process of employees repeatedly visiting stores with an automated voice collection and processing system. The system uses microphones to capture customer voices, transcribes them through speech recognition, and extracts price information automatically, eliminating the need for frequent physical store visits and associated operational costs

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables continuous price monitoring by operating continuously without interruption. The voice collection system runs constantly to capture customer evaluations, and the automated processing continuously extracts and analyzes price information, providing ongoing updates without the discontinuous nature of manual store visits

Inventive Principle:
Principle #20Continuity of useful action

3Loss of information

If the system requires manual input of voice and image data for price negotiation, then price evaluation information can be collected, but operational complexity increases

Engineering Contradiction:
Improveprice evaluation data collectionVSAvoidsystem operation complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically capturing voice data, transcribing it through speech recognition, and extracting price evaluation information without requiring manual input or complex operational procedures. The automated extraction mechanism processes the data independently, significantly simplifying the overall system operation while maintaining comprehensive data collection capability

Inventive Principle:
Principle #25Self-service
