Engineering Contradiction Analysis
1Productivity
If point-to-point narrow beam wireless paths are used for high-speed communication, then data throughput is improved, but reliability deteriorates due to sensitivity to line-of-sight disruptions and interference
Solution Approach 1:
The patent divides the wireless communication path into multiple segments by introducing intermediate relay nodes. Instead of direct point-to-point connections that are vulnerable to line-of-sight disruptions, the system uses multi-hop relay paths where each segment can independently maintain connectivity even if other segments fail, thus improving overall reliability while preserving high throughput capability.
Solution Approach 2:
The patent introduces relay nodes as intermediary elements between source and destination. These relay nodes receive signals from one node and forward them to another, creating redundant communication paths. The intermediary relay nodes enable the system to bypass blocked direct paths and maintain connectivity through alternative routes, directly addressing the reliability issue of narrow beam wireless paths.
2Reliability
If redundant communication paths are added to improve reliability, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The relay nodes in the patent are designed with multi-functionality, serving multiple purposes: they act as intermediate relays for signal forwarding, provide backup paths for failover, and can dynamically select optimal routes based on network conditions. This universal design allows a single node to handle multiple functions, reducing the need for separate dedicated components and thereby limiting the increase in device complexity despite adding redundancy.
Solution Approach 2:
The patent implements dynamic path selection where relay nodes can actively choose the best communication route based on real-time network conditions such as signal strength, interference levels, and connectivity status. This dynamic adaptability allows the system to automatically optimize its redundant paths without requiring manual configuration or complex static planning, thus improving reliability while keeping operational complexity manageable.
