Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If implicit geometry from building plan files is used directly, then the system can accept standard building plan formats, but the system cannot accurately compute or visualize RF propagation patterns due to lack of semantic information
Solution Approach 1:
The patent introduces an intermediary process that transforms implicit geometry from building plan files into explicit geometry with semantic information. This intermediary transformation layer enables the system to maintain compatibility with standard building plan formats while generating the detailed geometric data required for accurate RF propagation calculations.
Solution Approach 2:
The system performs preliminary geometry extraction and transformation before RF propagation computation. By pre-processing the building plan data to extract walls, floors, ceilings, and other structural elements with their semantic properties, the system prepares the necessary geometric foundation in advance, enabling subsequent accurate propagation analysis.
2Productivity
If 3D visualization of RF propagation is implemented, then network optimization capability is improved, but the system complexity increases due to geometry transformation requirements
Solution Approach 1:
The patent segments the complex geometry transformation process into distinct functional modules: extracting walls, extracting floors, extracting ceilings, and constructing 3D explicit geometry. This segmentation reduces system complexity by making each module independent and manageable, while collectively enabling comprehensive 3D visualization for network optimization.
Solution Approach 2:
The system automatically transforms implicit geometry to explicit geometry without requiring manual intervention. The geometry extraction and transformation processes are self-executing, taking building plan data as input and generating ready-to-use explicit geometry models for RF propagation analysis, thereby improving productivity despite increased processing complexity.

AI summary
The present technology is directed to visualizing a Wi-Fi signal propagation in 3-D based on a building plan defined with implicit geometry. The present technology can extract data from a building plan file where a 3-D space and objects in a building plan are defined with implicit geometry, transform the implicit geometry to explicit geometry for the 3-D space and the objects to translate a positioning of the 3-D space and objects from a local coordinate system to a global coordinate system, calculate a RF propagation pattern in the 3-D space based on a RF propagation model for a plurality of Wi-Fi access points located in the 3-D space, and present a 3-D visualization of the RF propagation pattern in the 3-D space.
