Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If graphical modeling tools are used to describe system architectures, then system models can be created, but the generated documents become inconsistent and fail to meet quality demands

Engineering Contradiction:

Improvedocument consistencyVSAvoidmodeling tool complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual document creation and enhancement processes with an automated conversion system that transforms textual system architecture descriptions into model-based descriptions using conversion rules and orchestration logic, eliminating inconsistencies caused by manual operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service through automated conversion orchestration where the conversion process automatically identifies, extracts, and transforms relevant information from textual descriptions into structured model-based representations without requiring manual intervention for each conversion task

Inventive Principle:

Principle #25Self-service

2Ease of operation

If documents are enhanced manually with images or graphics, then visual information can be added, but document consistency deteriorates and quality demands are not met

Engineering Contradiction:

Improvedocument enhancement flexibilityVSAvoiddocument consistency

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent replaces manual document enhancement operations with an automated conversion system that systematically transforms textual descriptions into model-based representations, ensuring consistent application of conversion rules and eliminating variability introduced by manual enhancement processes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If sophisticated document generators are used to create documents from models, then documents can be generated automatically, but the development and maintenance become very sophisticated and require continual maintenance

Engineering Contradiction:

Improvedocument generation automationVSAvoidgenerator maintenance complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent uses conversion rules that capture the essence of document generation requirements, allowing the system to replicate the desired document structure and content from textual descriptions directly, reducing the need for complex generator logic and its associated maintenance

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent extracts the essential conversion logic into separate, manageable conversion rules that can be independently developed and maintained, decoupling the complexity from the core document generation process and enabling easier updates and modifications

Inventive Principle:

Principle #2Taking out (Extraction)

4Manufacturing precision

If textual system architecture descriptions are converted into model-based descriptions automatically, then consistent system models can be created, but conversion orchestration logic is required

Engineering Contradiction:

Improvesystem model consistencyVSAvoidconversion orchestration complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the conversion process into distinct phases (identification, extraction, transformation, validation) with specific conversion rules for each phase, making the orchestration logic more manageable and easier to maintain while ensuring consistent model creation

Inventive Principle:

Principle #1Segmentation

AI summary

In order to create a system model, it is proposed that 1) in the course of the development of the technical system at least one partial architecture of the system should convert a textual system architecture description into a model-based system architecture description, 2) a computer-aided conversion orchestration, wherein a user-based data and command input and a logic-based data processing and command implementation are used to orchestrate the conversion in accordance with a stipulation based on a set of rules, should, in a first orchestration phase, use the system model, as conversion target model, to ascertain for a system development tool conversion rules for identifying partial aspects of a system architecture of the technical system to be developed, in a second orchestration phase, implement the conversion of the textual system architecture description into the model-based system architecture description iteratively for a partial-aspect-based description of the system architecture.
