Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices communicate independently in overlapping networks, then device autonomy and flexibility are maintained, but communication efficiency and coordination deteriorate
Solution Approach 1:
The patent introduces a network controller as an intermediary entity that coordinates communication among multiple devices in overlapping networks. The network controller receives communication requests, determines optimal transmission parameters, and manages resource allocation, thereby improving communication efficiency while preserving device autonomy through centralized coordination rather than direct device-to-device control.
2Productivity
If centralized control is implemented for managing communication groups, then communication coordination and efficiency improve, but system complexity and control overhead increase
Solution Approach 1:
The patent segments the communication group into multiple terminal devices and a network controller, with each terminal handling its own data transmission while the network controller manages coordination. This segmentation allows distributed execution of communication tasks, reducing the complexity burden on any single device while maintaining overall system coordination through the network controller.
3Reliability
If space-time block code matrices are allocated for cooperative transmission, then data integrity and reliability improve, but processing complexity and computational requirements increase
Solution Approach 1:
The patent implements preliminary allocation of space-time block code matrices by the network controller before actual data transmission occurs. The network controller determines and assigns appropriate code matrices to terminal devices based on channel conditions and transmission requirements, so that when data transmission occurs, the terminal devices can directly apply the pre-determined code matrices without performing complex real-time calculations, thus reducing processing complexity while maintaining data integrity.
