Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical site surveys and manual measurements are conducted, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent creates a virtual 3-D copy of the physical environment using building information model data, allowing signal propagation to be simulated and visualized without physical site surveys. The system generates a digital twin that replicates the spatial layout, materials, and geometry to compute signal behavior through electromagnetic wave propagation models, eliminating the need for manual on-site measurements while maintaining accuracy.
Solution Approach 2:
The patent replaces manual mechanical measurement processes with automated computational electromagnetic wave propagation simulations. Instead of physically measuring signal strength at various locations, the system uses ray tracing and finite difference time domain methods to calculate signal propagation paths, reflections, and interference patterns through the 3-D digital model, substituting physical survey work with virtual computation.
2Device complexity
If current wireless network planning tools are used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent segments the complex electromagnetic wave propagation problem into manageable computational components: identifying 3-D space regions, calculating signal paths through ray tracing, computing reflections and refractions at material interfaces, and synthesizing the results into a visual representation. This segmentation allows accurate simulation while maintaining user-friendly operation through automated processing of building information models.
Solution Approach 2:
The patent changes the fundamental parameters of signal propagation calculation by using 3-D spatial coordinates, material permittivity values, and frequency-dependent propagation models instead of simplified 2-D or empirical approaches. The system computes signal strength, signal-to-noise ratio, and interference patterns based on actual electromagnetic wave behavior in the 3-D environment, providing precise results without requiring complex manual configuration.
