Engineering Contradiction Analysis
1Area of stationary object
If additional wireless access points or relay nodes are introduced to extend wireless coverage, then coverage area is improved, but latency increases
Solution Approach 1:
The patent implements dynamic role reassignment where network nodes can switch between different functional roles (e.g., between nodes that perform analog processing and those that perform digital processing) based on real-time telemetry information. This dynamic adaptation allows the network to optimize latency performance while maintaining extended coverage by selectively routing traffic through nodes with appropriate processing capabilities.
Solution Approach 2:
The system changes operational parameters by collecting telemetry data from network nodes and using this information to reassign network roles. This parameter-based adaptation enables the network to adjust its behavior in response to changing conditions, optimizing both coverage and latency performance through intelligent resource allocation.
2Ease of operation
If a main node is used to orchestrate network communication, then network control is improved, but reliability deteriorates due to single point of failure
Solution Approach 1:
The patent segments the network control function by distributing orchestration capabilities across multiple nodes rather than concentrating it in a single main node. Each node can independently collect its own telemetry information and make autonomous decisions about its role, eliminating the single point of failure while maintaining effective network control through decentralized intelligence.
Solution Approach 2:
Network nodes perform self-service by autonomously collecting telemetry information about their own operational state and using this data to determine their optimal network role. This self-determination capability allows nodes to adapt to failures and reassign roles without requiring centralized control, thereby improving reliability while maintaining operational efficiency.
3Area of stationary object
If more wireless access points are added to extend range, then coverage is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing network nodes that can perform multiple roles depending on their operational state and telemetry data. Nodes can dynamically switch between different functional configurations (e.g., analog processing mode, digital processing mode, different routing roles), which reduces the need for specialized hardware at each node and simplifies overall network complexity while maintaining extended coverage.
