Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed protocol stack structure is adopted, then the system architecture is simple and generic, but the data transmission performance is degraded for terminals with specific characteristics
Solution Approach 1:
The patent implements dynamic protocol stack configuration where the protocol stack structure is adjusted based on terminal characteristics and service requirements. The network device determines appropriate protocol layers and parameters dynamically during connection establishment or reconfiguration, rather than using a fixed static configuration. This allows the system to adapt to different terminal types, service types, and data transmission characteristics while maintaining operational flexibility.
Solution Approach 2:
The patent changes protocol stack parameters including the number of protocol layers, specific layer configurations, and functional enablement based on terminal characteristics and service requirements. By modifying these parameters dynamically, the system achieves adaptability to different scenarios (e.g., IoT devices, mobile terminals, different service types) without requiring complete redesign of the protocol architecture.
2Adaptability or versatility
If protocol layers are added for comprehensive functionality, then the system can handle diverse services, but the transmission overhead increases
Solution Approach 1:
The patent extracts and removes unnecessary protocol layers from the protocol stack based on specific service requirements and terminal characteristics. For example, certain layers may be omitted for simple IoT devices or specific service types where their functions are not needed. This extraction reduces transmission overhead while maintaining sufficient functionality for the specific application scenario.
Solution Approach 2:
The patent applies partial protocol stack configuration where only the necessary subset of protocol layers is activated and configured based on service requirements. Instead of implementing the complete protocol stack for all scenarios, the system selectively enables only the required layers, achieving adequate functionality with reduced overhead for each specific application.
3Ease of manufacture
If a generic protocol stack architecture is used, then the system is easy to implement, but the data transmission efficiency is reduced for specific application scenarios
Solution Approach 1:
The patent designs a universal protocol stack configuration mechanism that can serve multiple different service types and terminal characteristics through dynamic adjustment. The same base architecture and configuration methodology can be applied across diverse scenarios (IoT, mobile broadband, different service types) by simply changing the configured parameters and layer structure, maintaining ease of implementation while achieving scenario-optimized performance.
