Solution Overview

Problem

The reliability of product reviews in online shopping malls is difficult to guarantee due to the cumbersome process of collecting customer opinions and the lack of credibility in existing reviews, which affects buyers' purchasing decisions.

Innovation Solution

A method and system for evaluating product reviews that includes displaying a search box on a buyer's terminal, inputting keywords, extracting relevant review information, and updating review evaluations based on user input, with features like URL links and reviewer identification to enhance review reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional review collection methods are used (manual photo taking, site visiting, typing), then review data can be collected, but the process becomes cumbersome and review reliability decreases

Engineering Contradiction:
Improvereview reliabilityVSAvoidreview collection ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically collects review data by utilizing the buyer terminal's existing functions (camera, GPS, input interface) without requiring separate dedicated review collection processes. The buyer terminal itself performs the review collection task by automatically capturing product images, location data, and review text when the buyer visits the product page, eliminating the need for manual data gathering processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-establishes review collection mechanisms by integrating review collection functionality into the product viewing process itself. When a buyer accesses a product page, the system proactively collects review data (images, location, text) in advance of any formal review submission, ensuring data is captured naturally during the browsing experience rather than requiring a separate review creation step.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If sellers implement various promotions to encourage review registration, then review quantity increases, but review authenticity and reliability remain compromised

Engineering Contradiction:
Improvereview quantityVSAvoidreview authenticity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system provides automatic feedback to buyers by displaying collected review data (product images, location information, review text) directly on the product page or in a review feed. This immediate feedback loop confirms that genuine purchase experiences are being captured and displayed, encouraging authentic reviews without requiring promotional incentives that might compromise authenticity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The buyer terminal acts as an intermediary that objectively captures and transmits review data from the buyer's actual product experience. By using the terminal's built-in sensors and input mechanisms to automatically record images, location, and text during natural browsing, the system creates an impartial data collection process that prevents manipulation and ensures authenticity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If buyers spend time taking photos, visiting sites, and typing reviews, then detailed review information is obtained, but the effort required makes the process cumbersome

Engineering Contradiction:
Improvereview information completenessVSAvoidreview creation time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The buyer terminal automatically performs all review data collection tasks (capturing product images via camera, recording location via GPS, transcribing review text via keyboard or voice input) without requiring the buyer to manually execute each step. The terminal's existing functionalities are leveraged to self-collect comprehensive review data during natural product browsing, eliminating the time burden while maintaining information completeness.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The review collection process is integrated into the continuous product browsing experience, occurring naturally as the buyer views product pages rather than requiring a separate discrete review creation step. Data collection continues seamlessly during normal site navigation, capturing images, location, and text in real-time without interrupting the buyer's workflow or requiring additional time investment.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

Disclosed are a method, a device, and a system for evaluating a product review. The method for evaluating a product review may: display, by using a server, a search box, through which the product review can be searched, on a buyer terminal; input a keyword on the basis of the search box; extract at least one piece of product review information as a search result corresponding to the input keyword; display the extracted product review information on the buyer terminal; and when a purchase decision is made in a shopping mall introduced on the basis of the displayed product review information, input, from the buyer terminal, a review evaluation corresponding to the product review. Therefore, it is possible to associate the review evaluation of the product review with the product review.
