Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If relay transmission is used to extend coverage, then the operating range is improved, but the network complexity increases
Solution Approach 1:
The network is segmented into source nodes, relay nodes, and destination nodes with clearly defined roles. Each node independently manages its own transmission and relay operations, dividing the complex relay transmission task into manageable segments that can be handled by individual devices according to their capabilities.
Solution Approach 2:
Wireless devices are designed with multi-functionality, capable of operating as source nodes, relay nodes, or destination nodes depending on network conditions. The relay capability indication mechanism allows devices to universally support multiple roles while maintaining simplified individual device designs.
2Productivity
If multi-traffic relay transmission is implemented, then the throughput is improved, but the difficulty of managing multiple traffic streams increases
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of standardized protocol layers and formatting rules that mediate between multiple traffic streams. These intermediaries organize and manage concurrent traffic from different sources to multiple destinations without requiring complex peer-to-peer coordination between all nodes.
Solution Approach 2:
The system dynamically changes parameters such as relay capability indications, traffic routing decisions, and transmission priorities based on network conditions. By adjusting these parameters, the system optimizes throughput for multi-traffic scenarios while keeping management complexity manageable through standardized parameter interfaces.
3Adaptability or versatility
If relay capabilities are indicated for each wireless device, then the adaptability of the network is improved, but the signaling overhead increases
Solution Approach 1:
Relay capabilities are indicated in advance during device initialization and network setup phases. This preliminary action allows the network to pre-configure relay paths and capabilities before actual data transmission begins, reducing the need for continuous signaling during operation and minimizing ongoing overhead.
