Solution Overview

Problem

In online shopping, customers cannot physically interact with products, limiting their access to comprehensive product information beyond appearance and packaging, while brick-and-mortar shopping provides limited information access.

Innovation Solution

A product information query system with a photographing module, distance detection module, and information query module that extracts product image features to obtain detailed information, including comment information, by detecting proximity of a product and using a pre-trained model for image analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If online shopping is used, then product information accessibility is improved, but physical product interaction capability deteriorates

Engineering Contradiction:
Improveproduct information accessibilityVSAvoidphysical product interaction capability
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The patent introduces an image recognition system as an intermediary between the physical product and the customer. The system captures images of the physical product, extracts features, and retrieves comprehensive information from a database, thereby bridging the gap between physical interaction and information accessibility without requiring the customer to leave the physical store.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the need for manual product examination and information search with an automated image recognition and processing system. The mechanical interaction of physically examining products is substituted with capturing product images and using computational algorithms to extract information and present comprehensive product details to the customer.

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

2Object-generated harmful factors

If brick-and-mortar shopping is used, then physical product interaction capability is improved, but product information accessibility deteriorates

Engineering Contradiction:
Improvephysical product interaction capabilityVSAvoidproduct information accessibility
Core Design Contradiction:
Object-generated harmful factorsVSLoss of information

Solution Approach 1:

The patent enables customers to independently query comprehensive product information by simply capturing images of products with their mobile devices. The system automatically processes the images, extracts product features, and retrieves relevant information without requiring store staff assistance, thereby maintaining physical interaction while improving information accessibility.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent substitutes manual information gathering methods (reading physical labels, asking staff) with automated image recognition and database querying. The system captures product images, extracts features using computer vision algorithms, and retrieves comprehensive information from centralized databases, transforming the information access process from manual to automated.

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

3Device complexity

If manual product information querying is used, then system complexity is reduced, but information query efficiency deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidinformation query efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-building comprehensive product information databases and training image recognition models in advance. Product information is organized and stored in structured databases before querying occurs, and image recognition algorithms are pre-trained to automatically identify product features. When a customer queries a product, the system can rapidly retrieve and present information without manual processing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual product information querying with automated image recognition and database retrieval systems. Computer vision algorithms automatically extract product features from images, and database systems automatically retrieve relevant information, eliminating the need for manual searching and significantly improving query efficiency while maintaining manageable system complexity through modular architecture.

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