Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If CAD drawings or blueprints are used to design wireless environments, then design efficiency is improved, but this method fails when such documents are unavailable or difficult to obtain
Solution Approach 1:
The patent replaces the mechanical/document-based CAD drawing input system with an RF signal-based electronic sensing system. Instead of requiring physical blueprints or manual CAD drawings as input, the system uses RF transceivers to electronically sense and automatically create environmental representations, eliminating dependency on unavailable documentation.
Solution Approach 2:
The system performs self-surveying by automatically sending RF signals, receiving reflections, and generating environmental models without human intervention. The wireless transceivers autonomously map the physical environment by detecting obstructions through RF signal interactions, eliminating the need for manual blueprint creation or input.
2Adaptability or versatility
If manual environment surveying is performed without design tools, then no prior documentation is needed, but the process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces slow manual surveying methods with automated RF-based electronic sensing. The system rapidly characterizes the environment by transmitting RF signals and processing reflections computationally, reducing time-consuming manual measurements while maintaining independence from existing blueprints.
Solution Approach 2:
The system performs preliminary environmental characterization automatically before wireless network deployment. By pre-mapping obstructions and environmental features using RF signals, the system prepares design data in advance, eliminating the need for time-consuming on-site surveys during the deployment phase.
3Ease of operation
If generic environmental models are used without site-specific data, then deployment is simplified, but wireless coverage optimization is compromised
Solution Approach 1:
The patent creates locally-specific environmental models by detecting actual obstructions and features at each deployment site using RF signals. Instead of applying generic models uniformly, the system captures site-specific characteristics such as wall locations, furniture arrangements, and structural features, enabling optimized wireless coverage tailored to each unique environment.
Solution Approach 2:
The system performs preliminary site-specific environmental mapping before network deployment. By pre-characterizing the local environment through RF sensing, the system prepares accurate location data and obstruction information in advance, enabling both simplified deployment procedures and reliable coverage optimization specific to each site.
