1Productivity

If manual selection of indoor object categories is performed, then construction accuracy is maintained, but construction efficiency deteriorates

Engineering Contradiction:

Improveconstruction efficiencyVSAvoidmanual operation requirement

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system automatically determines indoor object categories by analyzing layout data and spatial relationships without requiring manual user input. The computer executes algorithms that self-determine object categories based on positional relationships, area ratios, and pre-stored reference data, eliminating the need for manual category selection while maintaining accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary classification and analysis of layout data before final scenario construction. By pre-processing the spatial data, identifying object positions, and determining categories in advance through automated analysis, the system prepares the foundation for efficient construction without manual intervention during the actual building process

Inventive Principle:

Principle #10Preliminary action

2Productivity

If automated layout creation is implemented without category determination, then construction speed increases, but layout accuracy deteriorates

Engineering Contradiction:

Improveconstruction speedVSAvoidlayout accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system uses feedback mechanisms where the determined object categories and spatial relationships inform subsequent layout generation steps. The automated determination process continuously refines object placements based on spatial constraints, area ratios, and relationship rules, ensuring accuracy improves with each iteration while maintaining high construction speed

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts parameters such as object positions, areas, and spatial relationships during automated layout creation. By changing these parameters based on determined categories and constraint satisfaction, the system achieves both high construction speed and layout accuracy without manual intervention

Inventive Principle:

Principle #35Parameter changes
