Solution Overview

Problem

Users face difficulty in easily selecting ordered products from a large number of options available on digital catalogs in home delivery services, particularly when using voice input for product information.

Innovation Solution

A display device and method that acquires product information, extracts relevant ordered product candidates, and displays a user-friendly screen for selection, incorporating features like voice input and purchase history-based recommendations to facilitate easy product selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of product information pages are posted on a digital catalog, then the variety of products available for ordering is improved, but the difficulty for users to find and select ordered products increases

Engineering Contradiction:
Improveproduct varietyVSAvoidproduct selection difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the large number of product information pages into a smaller set of representative pages displayed on the thumbnail image. Each thumbnail represents a category or group of products, allowing users to navigate to specific product groups rather than browsing through all individual product pages. This segmentation reduces the visual complexity and makes product selection more manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces thumbnail images as an intermediary between the user and the full product information pages. These thumbnails serve as a mediating interface that summarizes multiple product pages into a single visual representation, enabling users to quickly identify and access relevant product categories without being overwhelmed by the sheer number of individual product pages.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If voice input is used to input product information, then the ease of operation is improved, but the precision of product specification decreases when multiple products match the search

Engineering Contradiction:
Improveproduct input convenienceVSAvoidproduct specification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent segments the search results into multiple thumbnail images, each representing a distinct product or product category that matches the voice input. Instead of presenting all matching products in a single undifferentiated list, the system divides them into discrete visual groups, allowing users to clearly distinguish between different product options and make precise selections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent provides visual feedback through thumbnail images that display product information corresponding to the voice input. This feedback mechanism allows users to verify whether the voice-recognized product information matches their intent by visually comparing the thumbnail content with their expected product, thereby maintaining specification accuracy despite the convenience of voice input.

Inventive Principle:
Principle #23Feedback
