Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If construction model layouts are created manually to ensure equipment functionality, then layout accuracy is improved, but design man-hours increase

Engineering Contradiction:
Improvelayout accuracyVSAvoiddesign man-hours
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system automatically generates construction model layouts by computing the minimum required area for equipment functionality and optimizing the arrangement of construction parts and passage parts without human intervention, thereby reducing design man-hours while maintaining layout accuracy

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes the parameter of layout generation from manual design to automated computation based on equipment functional requirements, transforming the design process into an algorithmic optimization problem that reduces time consumption while preserving accuracy

Inventive Principle:
Principle #35Parameter changes

2Reliability

If construction parts and passage parts are arranged to ensure equipment functionality, then layout effectiveness is improved, but design complexity increases

Engineering Contradiction:
Improvelayout effectivenessVSAvoiddesign complexity
Core Design Contradiction:

Solution Approach 1:

The system segments the layout design problem into distinct components: construction parts representing equipment, passage parts representing access routes, and minimum required area representing functional requirements. This segmentation allows automated computation while maintaining layout effectiveness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary computational layer that automatically generates layouts by processing equipment functional requirements and generating optimized arrangements, thereby reducing design complexity while maintaining layout effectiveness

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A construction-model-creating device with reduced design man-hours is realized. In equipment specifications including at least a positional relationship with a passage, specifications not determined by a user are enumerated based on specifications determined by the user and search conditions determined by the user according to the search conditions, and at least one of layout candidates representing a positional relationship between the equipment in the building and the passage is generated. When one of the generated layout candidates is selected by the user, an in-building equipment construction model part group reflecting a position, an orientation, specifications, and so on of the selected layout candidate is generated.
