Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WiFi hotspots are used for mobile broadband data services, then data transfer rate and power usage are improved, but coverage area is limited and usability for moving users deteriorates
Solution Approach 1:
The system segments the coverage area into multiple zones by deploying multiple small cell DERs along roadways. Each DER covers a specific segment, and together they form a continuous coverage network that allows moving users to seamlessly transition between segments while maintaining high-speed data access.
Solution Approach 2:
The patent transitions from two-dimensional ground-based WiFi hotspots to three-dimensional coverage by positioning DERs vertically along roadways and using directional antennas to create focused coverage zones. This dimensional approach enables continuous coverage for moving users while maintaining high data transfer rates within each zone.
2Area of stationary object
If cellular data networks are used for wider coverage, then coverage area is improved, but data transfer rate and power usage efficiency deteriorates
Solution Approach 1:
The system applies local quality by deploying small cell DERs with high-capacity wireless interfaces at specific locations along roadways where mobile users need access. Each DER provides localized high-speed data access, combining the wide coverage benefit of multiple distributed nodes with the high data transfer rate of cellular-grade wireless technology.
3Measurement precision
If traditional traffic monitoring systems are implemented, then traffic monitoring capability is provided, but integration with data communication infrastructure and comprehensive monitoring deteriorates
Solution Approach 1:
The patent merges traffic monitoring functions with data communication infrastructure by integrating RADAR units, cameras, and processors into the small cell DERs. This combination allows the system to simultaneously provide broadband data access and accurate traffic monitoring using shared hardware and processing resources, reducing overall system complexity while enhancing functionality.
Solution Approach 2:
The small cell DERs are designed as universal nodes that perform multiple functions: providing mobile broadband data access, monitoring vehicle speed via RADAR, capturing visual data with cameras, and reporting traffic information. This multi-functionality eliminates the need for separate dedicated traffic monitoring systems and integrates both services into a unified infrastructure.
