Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wireless topologies (5G/6G) are used, then network coverage and connectivity are maintained, but spectrum flexibility is compromised due to adversarial usage and commercial congestion
Solution Approach 1:
The patent implements dynamic DNN architecture generation that adapts to changing spectrum conditions in real-time. The control loop continuously monitors spectrum environment and generates optimized DNN architectures dynamically, allowing the system to respond to adversarial usage and commercial congestion while maintaining reliable network performance
Solution Approach 2:
The system changes key parameters including DNN architecture parameters, hardware resource allocation, and network operating parameters based on real-time spectrum conditions. This allows the network to optimize spectrum flexibility while maintaining performance by adjusting parameters rather than relying on fixed traditional topologies
2Productivity
If DNN architectures are customized for specific applications, then application performance is optimized, but system complexity increases
Solution Approach 1:
The control loop automatically generates optimized DNN architectures based on application requirements and real-time constraints without manual intervention. The system self-manages the complexity of customization by automating the DNN generation process, allowing high application performance while reducing operational complexity
Solution Approach 2:
The system pre-generates optimized DNN architectures for different application scenarios and constraints. By preparing multiple pre-optimized architectures in advance, the system can quickly deploy the appropriate architecture for each application without dealing with complexity during runtime
3Manufacturing precision
If hardware resources are allocated for high-performance DNN processing, then processing speed and accuracy improve, but cost and power consumption increase
Solution Approach 1:
The control loop dynamically adjusts DNN architecture parameters and hardware resource allocation based on real-time performance requirements and constraints. By changing parameters such as DNN depth, width, and hardware resource allocation, the system achieves high accuracy when needed while reducing power consumption during normal operation
Solution Approach 2:
The system allocates hardware resources partially or excessively based on real-time needs rather than maintaining full capacity continuously. The control loop determines the appropriate level of resource allocation required to meet current accuracy requirements, avoiding unnecessary power consumption
4Adaptability or versatility
If real-time feedback control loops are implemented, then system adaptability improves, but computational overhead and latency increase
Solution Approach 1:
The control loop uses pre-computed optimization results and cached DNN architectures to reduce real-time computational overhead. By performing preliminary analysis and preparation of optimized architectures, the system achieves real-time adaptability while minimizing the latency introduced by the feedback loop
