Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of communication devices is increased in cellular networks, then the network capacity is improved, but the device complexity and power consumption increase
Solution Approach 1:
The patent segments the network management function by introducing a dedicated network manager entity that separates control plane functions from user plane functions. This allows the cellular network to handle control signaling efficiently while offloading data traffic to the broadcast network, thereby managing complexity as the number of devices increases.
Solution Approach 2:
The patent introduces a broadcast network as an intermediary infrastructure to handle data transmission. The cellular network and broadcast network work together through defined interfaces, allowing the cellular network to focus on control functions while the broadcast network handles bulk data transmission, reducing the complexity burden on cellular network devices.
2Quantity of substance
If the network capacity is increased to serve more devices, then the coverage is improved, but the power consumption increases
Solution Approach 1:
The patent enables periodic or on-demand activation of network resources by allowing devices to switch between cellular network (for control and small data) and broadcast network (for bulk data transmission). This periodic utilization pattern reduces continuous power consumption while maintaining network capacity.
Solution Approach 2:
The broadcast network acts as an intermediary that handles power-intensive data transmission tasks, allowing cellular network transmitters to operate at lower power levels for control signaling only, thereby reducing overall power consumption while maintaining network capacity.
3Productivity
If the data transmission capacity is increased for high-demand events, then the service quality is improved, but the network congestion increases
Solution Approach 1:
The patent extracts data transmission functions from the cellular network and relocates them to the broadcast network. During high-demand events, bulk data transmission is taken out from the cellular network infrastructure and handled by the broadcast network, preventing cellular network congestion while maintaining high data transmission capacity.
Solution Approach 2:
The patent changes the operational parameters of the network by introducing dual-network connectivity modes. Devices can dynamically switch between unicast (cellular) and broadcast (broadcast network) transmission modes based on traffic demands, allowing the system to scale data transmission capacity without proportionally increasing cellular network congestion.
4Loss of time
If the latency is reduced for live media services, then the user experience is improved, but the network load increases
Solution Approach 1:
The broadcast network serves as an intermediary that provides low-latency direct-to-device data transmission for live media services. By bypassing the cellular network's multi-hop routing for bulk data delivery, the system achieves lower latency while the cellular network's load is reduced to only control signaling and device management functions.
