Solution Overview

Problem

Existing digital content systems inaccurately group content items based on simplistic factors like file type and access time, leading to inefficient user interactions and resource consumption due to misplaced content items and rudimentary clustering that fails to reflect user activity patterns.

Innovation Solution

The content scene system generates content clusters based on topic data and focus data using machine learning models, allowing for accurate grouping of content items by theme and activity patterns, and provides interfaces for restoring application sessions and creating content collections with minimal user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing systems group content items by file type and access time, then the clustering process is simple and fast, but the accuracy of content grouping deteriorates significantly

Engineering Contradiction:
Improveclustering speedVSAvoidcontent grouping accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system changes the clustering parameters from simple metadata (file type, access time) to enriched features including NLP-derived topic representations, user behavior patterns, and contextual metadata. This parameter transformation enables accurate semantic clustering while maintaining computational efficiency through optimized feature extraction and embedding techniques.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces mechanical sorting methods (simple file system sorting by name or date) with intelligent information processing systems that use machine learning models, NLP algorithms, and automated topic modeling to achieve accurate content grouping without manual intervention.

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

2Device complexity

If existing systems use rudimentary clustering methods, then the system complexity is low, but the user interaction efficiency deteriorates due to misplaced content items

Engineering Contradiction:
Improvesystem complexityVSAvoiduser interaction efficiency
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically analyzing user behavior patterns, inferring content relationships, and organizing content collections without requiring user input. The system monitors user interactions, learns preferences, and autonomously creates accurate groupings, eliminating the need for manual content sorting and reducing user interaction overhead.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by pre-processing content items to extract features, generate topic representations, and establish relationships before user interaction is needed. This preparation enables fast and accurate content retrieval and grouping during actual user operations, significantly improving interaction efficiency.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If existing systems generate content collections individually, then each collection can be precise, but the overall process time and resource consumption increase significantly

Engineering Contradiction:
Improvecollection precisionVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges multiple content collection generation tasks into a single unified process that simultaneously creates multiple themed collections from the same input data. By combining collection generation with content analysis, topic modeling, and relationship extraction in one operation, the system achieves both high precision and reduced processing time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements a universal content analysis engine that serves multiple functions: topic extraction, relationship detection, collection generation, and recommendation creation. This multi-functional approach eliminates redundant processing steps and enables efficient generation of multiple precise collections from a single analysis pass.

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