Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual interpretation of piping diagrams is used to define operational requirements, then flexibility in handling complex cases is maintained, but time consumption and potential for errors increase

Engineering Contradiction:
Improveaccuracy of operational requirementsVSAvoidtime for system planning
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical interpretation of piping diagrams with automated computer-based analysis. The system automatically extracts operational requirements from piping diagrams using image processing and pattern recognition algorithms, eliminating the need for manual document review while maintaining accuracy through structured data extraction methods.

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

Solution Approach 2:

The system enables self-service automation where the piping diagram itself contains all necessary information for automatic operational requirement extraction. The automated system processes the diagrams without requiring external manual intervention, using embedded metadata and standardized symbols to generate operational requirements autonomously.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple separate tools are used for piping diagram creation and automation function generation, then specialized functionality is maintained, but system complexity and integration effort increase

Engineering Contradiction:
Improvespecialized functionalityVSAvoidnumber of software tools
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges piping diagram creation and automation function generation into a single integrated software system. The system combines plant planning tool capabilities with automated operational requirement extraction and automation function generation, allowing users to complete the entire workflow from diagram creation to automation generation without switching between multiple separate tools.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The software system performs multiple functions within a single platform: it creates and edits piping diagrams, automatically extracts operational requirements, generates automation functions, and produces documentation. This multi-functional approach eliminates the need for separate specialized tools while maintaining all necessary capabilities.

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

3Loss of information

If separate documentation is created for operational requirements, then detailed specifications are maintained, but documentation overhead and synchronization complexity increase

Engineering Contradiction:
Improveoperational requirement detailsVSAvoiddocumentation management
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts operational requirements directly from the piping diagram data structures and metadata, removing the need for separate documentation files. The system identifies and extracts operational requirements by analyzing diagram symbols, connections, and embedded information, converting visual diagram data into structured operational requirement specifications automatically.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses the piping diagram data structure as an intermediary between the visual diagram and operational requirements. Instead of creating separate documentation, the diagram itself serves as the source and storage medium for operational requirements, with the software acting as a mediator that translates diagram elements into automation-ready specifications.

Inventive Principle:
Principle #24Intermediary (Mediator)
