Solution Overview

Problem

Existing digital content systems inaccurately group content items based on rudimentary factors like file type and access time, leading to inefficient user interactions and excessive resource consumption due to misplaced content items and inefficient user interfaces.

Innovation Solution

The content scene system generates content clusters based on topic data and focus data using machine learning models to group items by theme and activity patterns, allowing for single-click restoration of application sessions and efficient generation of content collections, while storing and restoring desktop and video call scene layouts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing systems use rudimentary clustering by file type and access time, then the system complexity is low, but the clustering accuracy is poor and content items are misplaced

Engineering Contradiction:
Improveclustering accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent transforms the clustering approach from using simple parameters (file type, access time) to using enriched parameters including topic data extracted via NLP, focus data from user activity patterns, and session-based temporal information. This parameter enrichment enables accurate topic-based clustering while maintaining system manageability through modular implementation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces topic data and focus data as intermediary elements that mediate between raw content items and clustering results. Topic data serves as a semantic intermediary that bridges content items with their thematic categories, while focus data acts as an behavioral intermediary that captures user engagement patterns, together enabling accurate clustering without excessive system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If existing systems generate content collections from inaccurate clusters, then the system operation is simple, but excessive user interactions are required to relocate misplaced content items

Engineering Contradiction:
Improveuser interaction efficiencyVSAvoidtime for relocating content
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary clustering of content items into topic-based groups before generating content collections. By pre-organizing content items according to their semantic topics and user focus patterns, the system eliminates the need for subsequent user-driven relocation operations, thereby improving productivity and reducing time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent incorporates focus data derived from user activity patterns as feedback to refine clustering accuracy. By continuously monitoring how users interact with content items and using this feedback to adjust clustering parameters, the system dynamically improves content organization, reducing the need for manual relocation and enhancing user interaction efficiency.

Inventive Principle:
Principle #23Feedback

3Device complexity

If existing systems require accessing content items individually through separate device interactions, then the interface simplicity is maintained, but the processing of excessive user interactions consumes computing resources

Engineering Contradiction:
Improveinterface complexityVSAvoidcomputing resource consumption
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple individual content item access operations into a single batch operation through content collections. Instead of requiring separate device interactions for each content item, the system combines related content items into themed collections that can be accessed and manipulated as unified groups, thereby reducing interface complexity and computing resource consumption.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates content collections that serve multiple functions simultaneously: they organize content by topic, enable batch access operations, provide contextual relationships between items, and reduce the number of required user interactions. This multi-functionality approach maintains interface simplicity while significantly reducing computing resource consumption.

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

4Loss of information

If existing systems group content items without considering contextual factors, then the clustering process is fast, but the generated content collections provide no insight into themes or user activity patterns

Engineering Contradiction:
Improvetheme and activity pattern informationVSAvoidtime for processing contextual data
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent performs preliminary extraction of topic data and focus data from content items and user activity logs before the clustering process. By pre-processing and storing these contextual attributes, the system enables fast clustering operations that incorporate rich thematic and behavioral information without incurring excessive processing time during actual clustering operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical clustering methods with topic-based semantic clustering using NLP techniques. Instead of relying on simple rule-based grouping, the system uses natural language processing to extract meaningful topics and themes from content items, and uses machine learning to analyze user activity patterns, thereby preserving information while maintaining efficient processing.

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