Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multi-beam smart antennas (MBSAs) are used to focus energy on specific directions, then transmission distance and data rate are improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the network into hierarchical levels (high-level nodes with MBSAs and low-level nodes with simpler antennas) to segment the complexity. MBSAs are deployed only where needed for long-distance, high-rate transmissions, while other nodes use simpler omni-directional or single-beam antennas, reducing overall system complexity while maintaining high throughput capabilities.
Solution Approach 2:
The patent applies different antenna types to different locations and functional requirements within the network. High-level nodes that require long-distance communication and high data rates are equipped with MBSAs, while low-level nodes use simpler antenna systems. This local differentiation optimizes performance where needed while controlling overall system complexity.
2Productivity
If hierarchical hybrid wireless network (H2WN) with multi-level topology is implemented, then network management and cost-effectiveness are improved, but routing efficiency and data delivery speed deteriorate
Solution Approach 1:
The patent implements proactive routing mechanisms where routing paths are pre-established and cached before data transmission is needed. Nodes maintain routing tables with pre-computed paths to various destinations, allowing immediate data forwarding without extensive real-time path discovery, thus reducing routing delay in the hierarchical network.
Solution Approach 2:
The patent introduces high-level nodes as intermediary relay points in the hierarchical network. These nodes with MBSAs serve as strategic forwarding points that can efficiently route data between different regions of the network, reducing the number of hops and overall transmission time compared to direct low-level node-to-node routing.
3Ease of manufacture
If omni-directional antennas are used to reduce cost, then device cost is reduced, but transmission distance and data rate deteriorate
Solution Approach 1:
The patent combines omni-directional antennas at low-level nodes with multi-beam smart antennas at high-level nodes to create a hybrid system. The omni-directional antennas provide wide coverage and basic connectivity at low cost, while the MBSAs at strategic high-level nodes provide high-rate long-distance transmission capabilities, achieving overall high throughput without requiring every node to have expensive MBSAs.
4Reliability
If directional antennas with single beam are used to avoid interference, then transmission reliability is improved, but network throughput and data delivery speed deteriorate
Solution Approach 1:
The patent transitions from single-beam directional antennas to multi-beam smart antennas that operate in the angular dimension. MBSAs can form and control multiple independent beams simultaneously in different directions, allowing parallel data transmissions to multiple destinations without interference, thus increasing network throughput while maintaining transmission reliability through directional focusing.
