Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless networks provide diverse customized services, then service versatility is improved, but network complexity increases
Solution Approach 1:
The patent segments the network into multiple virtual networks (VNs), each customized for specific service requirements. The network management system divides the complex task of serving diverse services into separate virtual network instances, where each VN handles specific service types with dedicated resources and configurations, thereby managing complexity through division while maintaining service versatility.
Solution Approach 2:
The patent implements a universal network management system that can create and manage multiple virtual networks with different service requirements using a single platform. The system provides multi-functional capabilities to handle various service types (e.g., broadband, IoT, critical communications) through a unified architecture, reducing overall system complexity while maintaining adaptability to diverse services.
2Quantity of substance
If wireless networks integrate various resources densely, then network capacity is improved, but resource management difficulty increases
Solution Approach 1:
The patent introduces virtual network functions (VNFs) as intermediary elements between physical network resources and service requirements. These VNFs act as mediators that manage and orchestrate diverse network resources (spectrum, antennas, processing power) in a standardized manner, reducing the complexity of directly managing integrated resources while maximizing network capacity utilization.
Solution Approach 2:
The patent creates virtual copies of network resources through virtualization technology. Instead of managing physical resources directly, the system creates virtual representations (virtual networks, virtual functions) that can be dynamically allocated and managed. This copying approach simplifies resource management by working with abstracted virtual entities rather than complex physical infrastructure.
3Productivity
If wireless networks use high carrier frequencies with more antennas, then network performance is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation and configuration in virtual networks to manage complex high-frequency systems. The system can dynamically adjust antenna configurations, beamforming parameters, and resource allocation based on service requirements and network conditions, making the complex hardware system adaptable and manageable through software-controlled dynamics rather than fixed complex configurations.
4Reliability
If wireless networks enable seamless transitions between interfaces, then service reliability is improved, but control complexity increases
Solution Approach 1:
The patent introduces virtual network functions and control plane entities as intermediaries that manage transitions between different wireless interfaces (e.g., 5G NR, LTE, WiFi). These intermediary control elements handle the complexity of interface coordination, authentication, and resource allocation, enabling seamless handovers and multi-access connectivity while keeping the control logic centralized and manageable rather than distributed across multiple complex interface controllers.
