Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual data marking and structuring is performed to train AI algorithms, then the system can recognize specific scenarios, but it requires an enormous amount of work and time

Engineering Contradiction:
Improvedata recognition accuracyVSAvoiddata marking time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs self-service by automatically generating structured data from unstructured production documents using NLP technology. The algorithm automatically extracts entities, relationships, and attributes without requiring manual marking, thereby resolving the contradiction between recognition accuracy and time consumption

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual marking process with an automated NLP-based system. The algorithm automatically structures unstructured text data into machine-readable formats, substituting human labor with intelligent automation to achieve both accuracy and efficiency

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

2Reliability

If engineers manually investigate and observe to mark and structure data, then accurate production data can be obtained, but it takes weeks to communicate with operators and managers

Engineering Contradiction:
Improvedata accuracyVSAvoiddata processing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical process of manual investigation and communication with an automated NLP system that directly processes production documents. The algorithm extracts and structures data automatically, eliminating the need for engineers to spend weeks communicating with operators and managers while maintaining data accuracy

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

Solution Approach 2:

The NLP algorithm acts as an intermediary between unstructured production documents and the automated control system. It automatically translates document content into structured data formats, serving as a mediator that eliminates the need for manual intervention while ensuring accurate data transmission

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If legacy devices with limited data interfaces are used, then existing factory equipment can be utilized, but they cannot provide abundant information for product process monitoring and optimization

Engineering Contradiction:
Improvedevice compatibilityVSAvoidprocess information availability
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary layer (the NLP-based data extraction system) that bridges legacy devices and the monitoring system. By processing production documents associated with legacy devices, the system extracts additional information that compensates for the limited interfaces of legacy equipment

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a digital copy or representation of production data from documents associated with legacy devices. This virtual copy contains structured information that supplements the limited data available from legacy device interfaces, enabling comprehensive monitoring without modifying the original devices

Inventive Principle:
Principle #26Copying
