Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual sorting method is used to organize event themes, then the accuracy and quality of theme organization can be maintained through human judgment, but the labor cost and time consumption increase significantly

Engineering Contradiction:
Improvetheme organization accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables automatic theme generation where the computational system performs theme extraction and organization autonomously without human intervention. The deep learning model and knowledge graph automatically process event information, extract entities, and generate themes, replacing manual sorting operations while maintaining efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual sorting process with an automated computational system combining deep learning for entity recognition and knowledge graphs for semantic understanding. This substitution eliminates physical human labor in theme organization while achieving scalable processing of large volumes of event data.

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

2Reliability

If manual sorting method is used to organize event themes, then the quality control can be maintained through human expertise, but the productivity and output volume decrease

Engineering Contradiction:
Improvetheme qualityVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system autonomously performs theme extraction, entity recognition, and organization without requiring human operators. The deep learning model automatically identifies entities and events, the knowledge graph structures the information semantically, and themes are generated automatically, achieving both high productivity and consistent quality through automated decision-making processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent transforms the quality control mechanism from human subjective judgment to automated computational analysis with objective criteria. The system uses configurable parameters such as entity recognition thresholds, event type classifications, and theme template matching rules to maintain consistent quality standards across large volumes of processed data.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated theme generation is implemented using deep learning and knowledge graphs, then the processing speed and productivity improve significantly, but the system complexity and technical requirements increase

Engineering Contradiction:
Improvetheme generation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the complex theme generation task into distinct modular components: deep learning model for entity and event recognition, knowledge graph for semantic relationship modeling, and template-based theme generation. Each module handles a specific aspect of processing, reducing overall system complexity through functional decomposition while maintaining high productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The knowledge graph serves as an intermediary layer between the deep learning recognition system and the theme generation output. It structures extracted entities and events with semantic relationships, providing a standardized intermediate representation that simplifies the final theme generation process and bridges the gap between raw data processing and structured output.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If automated theme generation is implemented, then the labor cost and manual intervention are reduced, but the initial development cost and technical resources required increase

Engineering Contradiction:
Improveoperational simplicityVSAvoiddevelopment cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The system performs preliminary actions by pre-training deep learning models on domain-specific data and pre-con structing knowledge graphs with relevant entities and relationships before deployment. This preliminary preparation work, though resource-intensive during development, enables the system to operate with minimal intervention during actual theme generation, achieving operational simplicity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses template-based theme generation where standardized theme patterns are created in advance. These templates serve as reusable copies that can be rapidly instantiated with different entity and event data, reducing the need for custom theme creation logic and lowering operational complexity while maintaining consistent quality across diverse inputs.

Inventive Principle:
Principle #26Copying

AI summary

The present disclosure provides a method for generating an event theme, belonging to a field of knowledge graph technologies and a field of deep learning technologies. Pieces of event information in an associated relation are obtained. Entity information and an event type of each piece of event information are obtained. Target event information having representative attributes is obtained from the pieces of event information. A theme template matching the event type of the target event information is selected from a theme template collection. The entity information and the event type of the target event information are added into the theme template to generate a theme of the pieces of event information.
