Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a traditional cloud-based network architecture is used, then centralized control and management are simplified, but response delay increases and service continuity deteriorates under dynamic environmental changes
Solution Approach 1:
The patent segments the centralized cloud network into distributed edge computing nodes deployed throughout the 5G mesh network. Each edge node independently processes data locally, eliminating the single-point bottleneck of traditional cloud architecture and reducing response delay while maintaining manageable complexity through modular deployment
Solution Approach 2:
The patent introduces a new dimensional approach by deploying edge computing nodes in three-dimensional space throughout the network infrastructure, transforming the traditional two-dimensional flat cloud architecture into a spatially distributed multi-layered structure that reduces latency while distributing complexity across multiple dimensions
2Productivity
If infrastructure investment is increased to enhance coverage and throughput, then network capacity improves, but deployment cost increases significantly
Solution Approach 1:
The patent makes existing edge devices serve multiple functions: they act as both 5G mesh network nodes for wireless communication and edge computing nodes for data processing. This multi-functionality increases network capacity and throughput without requiring separate dedicated infrastructure, thereby avoiding significant additional investment
Solution Approach 2:
The patent enables edge devices to autonomously perform computing tasks locally without requiring additional centralized infrastructure. Each edge device serves itself by processing data in-place, eliminating the need for extensive additional infrastructure investment while maintaining high throughput and capacity
3Loss of time
If edge devices are deployed closer to user equipment to reduce latency, then response time improves, but network complexity and deployment difficulty increase
Solution Approach 1:
The patent implements dynamic path selection in the 5G mesh network, where communication routes are automatically adjusted in real-time based on environmental conditions, device availability, and traffic patterns. This dynamic adaptability reduces response delay while simplifying deployment, as the system self-optimizes without requiring complex static configuration
4Reliability
If the network dynamically adapts to environmental changes, then service continuity improves, but system complexity and processing overhead increase
Solution Approach 1:
The patent pre-establishes multiple alternative communication paths between edge devices in the 5G mesh network before environmental changes occur. When disruptions are detected, the system immediately switches to pre-configured backup paths, ensuring service continuity without requiring complex real-time decision-making algorithms or increasing overall system complexity
Data Source
AI summary
A communication system includes a first edge device that obtains timing information at a first time instant from a radio access network (RAN) node or a central cloud server. The timing information is indicative of a unique system frame number or a sub-frame of the unique system frame number that is to be received at the first edge device. The first edge device detects the unique system frame number or the sub-frame of the unique system frame number at a second time instant. The first edge device executes a switching event in which a new communication link is established with a second edge device. The first edge device periodically checks whether the new communication link has a signal strength greater than a threshold to maintain a continuity in an uplink communication and a downlink communication between one or more user equipment (UEs) and the RAN node via the mesh network.
