Solution Overview

Problem

Existing search engines face challenges in efficiently categorizing diverse datasets, leading to broad categories that fail to describe niche items accurately, and creating narrow categories results in an unmanageable database scheme.

Innovation Solution

A multiple taxonomy system that allows for custom taxonomies based on user-defined categories, enabling finer granularity in search results navigation by identifying and utilizing custom UI taxonomies for specific item classes, such as 'bricks with a slope' or 'angled bricks', and integrating custom content like videos and social media feeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If broad categories are used to categorize diverse datasets, then database manageability is improved, but search result precision and user navigation efficiency deteriorate

Engineering Contradiction:
Improvedatabase manageabilityVSAvoidcategory precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the categorization system into multiple independent taxonomy layers (e.g., category, subcategory, niche attributes) that can be applied hierarchically. Each layer segments the diverse dataset into progressively finer groups, allowing broad categories for manageability while nested narrower categories provide precision for specific item classes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces multiple classification dimensions (taxonomies) that operate simultaneously rather than a single hierarchical dimension. Items can be categorized along different axes (e.g., functional category, brand, price range, specific attributes) allowing the system to maintain broad organizational structure while providing precise filtering capabilities through multi-dimensional classification.

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

2Measurement precision

If narrow categories are used to categorize diverse datasets, then search result precision is improved, but database complexity and manageability worsen

Engineering Contradiction:
Improvecategory precisionVSAvoiddatabase complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the categorization responsibility across multiple taxonomy layers, with each layer handling a specific aspect of classification. Narrow categories are confined to specific layers or applied only to relevant item classes, preventing the entire database scheme from becoming unmanageably complex while still providing precise categorization where needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different levels of categorization granularity to different item classes based on their specific needs. Certain item classes receive detailed narrow-category classification while others use broader categories, optimizing the balance between precision and manageability locally for each category rather than applying a uniform structure throughout.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If custom taxonomies are implemented for specific item classes, then user navigation efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveuser navigation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a universal taxonomy framework that can accommodate multiple custom taxonomies for different item classes through a common structural design. The system uses standardized data structures and interfaces that work across all taxonomy types, allowing custom categorizations to be added without fundamentally changing the core system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent makes the taxonomy system dynamic and adaptable, allowing custom taxonomies to be configured and applied based on the specific item class being searched. The system can dynamically select and apply appropriate taxonomies rather than using a fixed rigid structure, enabling flexible navigation while maintaining systematic organization through configurable parameters.

Inventive Principle:
Principle #15Dynamics

AI summary

An item query can be received on a website that manages a diverse set of items. If the query is associated with a custom taxonomy, the custom taxonomy for the item (or item class) is used to create a user interface with navigational elements generated from the custom taxonomy. The custom taxonomy can be generated from a third-party site that is associated with the item (e.g., a manufacturer). The generated user interface allows users to more readily navigate items from the item class.
