Engineering Contradiction Analysis
1Area of stationary object
If more wireless access points or relay nodes are introduced to extend the communication range, then the wireless coverage is extended, but the latency increases
Solution Approach 1:
The system segments the backhaul connection into multiple wireless hops between mesh nodes, allowing coverage extension without requiring each node to transmit over long distances. This segmentation maintains lower latency per hop while achieving broad area coverage through coordinated multi-node transmission.
Solution Approach 2:
The patent introduces spatial dimensionality through 3D positioning and beamforming techniques. By utilizing three-dimensional space for signal propagation and node placement, the system extends coverage vertically and horizontally without proportionally increasing latency, as signals travel more direct paths through optimized spatial routing.
2Reliability
If hybrid analog-digital repeater devices with dual analog data links are deployed, then interference resistance is improved, but device complexity increases
Solution Approach 1:
The patent merges analog and digital processing functions within a single hybrid repeater device. The analog data links handle signal transmission while digital processors manage telemetry analysis and switching decisions, combining the simplicity of analog signal paths with the intelligence of digital control to achieve interference resistance without excessive complexity.
Solution Approach 2:
The system introduces telemetry information as an intermediary that mediates between the analog data links and digital control functions. This intermediary layer provides real-time channel quality feedback, enabling intelligent switching and resource allocation that simplifies the overall device architecture by automating complex decision-making processes.
3Productivity
If telemetry information-based intelligent switching is implemented, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements feedback loops where telemetry information from channel quality measurements is continuously monitored and fed back to the intelligent switching controller. This feedback mechanism enables automatic adaptation to changing channel conditions, improving communication efficiency while keeping the system manageable through rule-based decision algorithms rather than complex optimization computations.
Solution Approach 2:
The intelligent switching system performs self-service by automatically analyzing telemetry data and making routing decisions without external intervention. The mesh nodes autonomously adjust their transmission parameters and switch between analog and digital links based on real-time channel conditions, reducing the need for complex centralized control while maintaining high communication efficiency.
