Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional GIS systems are used for spatial analysis and mapping, then broad land-use analysis capabilities are provided, but geometric precision and accuracy required for precision engineering tasks are not maintained
Solution Approach 1:
The patent merges CAD and GIS systems into an integrated platform that combines the geometric precision of CAD with the spatial analysis capabilities of GIS. The system allows users to work with both precise engineering drawings and geographic data in a unified environment, eliminating the need to choose between precision and versatility.
Solution Approach 2:
The integrated system provides multi-functionality by enabling users to perform both precision engineering tasks and broad spatial analysis within the same software environment. The system can handle both detailed CAD drawings and GIS-based land-use analysis, making it universally applicable to various engineering and planning tasks.
2Adaptability or versatility
If data is imported or digitized from CAD drawings to GIS mapping environment, then GIS mapping functionality is utilized, but data connectivity, accuracy, and geometric precision are lost
Solution Approach 1:
The system merges CAD and GIS data structures into a unified framework where data can be shared between the two environments without loss of connectivity or accuracy. The integrated architecture ensures that geometric precision is maintained while enabling GIS mapping functionality.
Solution Approach 2:
The patent introduces an intermediary data structure that acts as a mediator between CAD and GIS systems. This intermediary layer ensures that data can be exchanged between the two systems while maintaining both the geometric precision of CAD and the mapping capabilities of GIS, preventing data loss during transitions.
3Quantity of substance
If complex databases are used to model real-world objects in GIS, then spatial data storage is improved, but ability to store geometric objects in traditional CAD application is not achieved
Solution Approach 1:
The patent creates a universal data structure that can store both traditional CAD geometric objects and GIS spatial data in the same database system. This multi-functional database approach allows the system to handle both precise geometric data from CAD and extensive spatial data from GIS without requiring separate storage systems.
Data Source
AI summary
A CAD/GIS system that automatically generates faces within land site maps, by sliding or rotating line segments between boundaries given start points and other attributes. As the attributes are entered into the system, faces are automatically generated based on those attributes, which eases creation of lots within subdivisions.
