Solution Overview

Problem

Existing e-commerce systems face challenges in presenting product listings to users, leading to selection errors due to textual misinterpretation, which reduces the likelihood of successful transactions.

Innovation Solution

Presenting item listings in silhouette form, allowing users to select and view attributes through mouseover functionality, thereby reducing selection errors and enhancing the user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If item listings are presented using textual names only, then the system can display a large number of items, but selection errors occur when users choose the incorrect item name

Engineering Contradiction:
Improvenumber of item listingsVSAvoidselection accuracy
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent transitions from one-dimensional textual item names to two-dimensional visual silhouettes combined with text. This dimensional enhancement allows users to identify items through visual shape recognition in addition to text, significantly reducing selection errors while maintaining the ability to display numerous items.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces silhouettes as an intermediary visual element between the user and the full item details. These silhouettes serve as a mediating representation that helps users accurately identify items before viewing complete attributes, thereby improving selection accuracy without limiting the quantity of displayable items.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If item listings are displayed with full visual details, then selection accuracy improves, but the number of items that can be practically presented decreases

Engineering Contradiction:
Improveselection accuracyVSAvoidnumber of item listings
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies different levels of visual detail to different parts of the interface. Silhouettes provide essential visual identification locally, while full item details are available on-demand. This localized visual enhancement improves selection accuracy without requiring all items to display complete visual details simultaneously.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments item presentation into distinct components: visual silhouettes for identification, textual names for search, and detailed attributes for confirmation. This segmentation allows each element to serve its specific function efficiently, maintaining high selection accuracy while maximizing the number of items that can be presented.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If users must read and interpret textual item names, then the system can handle diverse item categories, but user time and cognitive load increase

Engineering Contradiction:
Improveitem category coverageVSAvoiduser selection time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent leverages visual pattern recognition (a form of rapid cognitive processing) through silhouettes, which allows users to quickly identify item types without extensive textual reading. This visual mechanism processes information faster than text interpretation while maintaining adaptability across diverse item categories.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The patent substitutes visual silhouette recognition for text-based identification. This replacement reduces the cognitive mechanical process from reading and interpreting text to rapidly recognizing visual shapes, significantly decreasing user selection time while preserving the ability to handle diverse item categories.

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

AI summary

Methods and systems for displaying, to a user interface, categories of items for the user to select from for querying the system, in order to enable the system to return to the user images of items of the type desired by the user for possible purchase. The items categories of items can be presented to the user interface visually in silhouette form so that the user can select brand and the silhouette image of the type of item desired. Upon selection of the silhouette image, a query is sent to the system and images of the desired type of item are returned to the user interface for presentation to the user, along with certain attributes of the items.
