Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of links per communication node is increased to improve network connectivity, then network reliability is improved, but the number of required channels increases beyond available resources
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the threshold value for link establishment based on the ratio of available channels to required channels. When channel resources are limited, the threshold is increased to reduce the number of links established, preventing channel exhaustion while maintaining essential network connectivity.
Solution Approach 2:
The system dynamically adapts the link establishment criteria based on real-time channel availability. The threshold parameter is not fixed but changes according to network conditions, allowing the system to optimize between connectivity and resource constraints by adjusting link selection behavior in response to available channel resources.
2Reliability
If antenna panels are added to communication nodes to improve transmission quality, then network performance is improved, but device complexity increases
Solution Approach 1:
The patent implements partial action by establishing a threshold that prevents all potential links from being created. Even when multiple antenna panels could provide transmission paths, the system selectively establishes only those links that meet the threshold criteria, avoiding unnecessary complexity while maintaining sufficient transmission quality.
Solution Approach 2:
The system applies local quality by evaluating each potential link individually against the threshold criteria rather than uniformly applying a fixed configuration. This allows antenna panels to be utilized selectively based on local network conditions and channel availability, optimizing transmission quality where needed while avoiding unnecessary complexity elsewhere.
3Reliability
If channel allocation is optimized to reduce interference, then network reliability is improved, but the initialization time and computational complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and establishing a threshold value before actual link formation begins. This preliminary threshold determination simplifies subsequent link establishment decisions, reducing the computational complexity and time required during network initialization while still achieving interference reduction through selective link formation.
Solution Approach 2:
The system uses parameter changes by adjusting the threshold based on the ratio of available channels to required channels. This dynamic parameter adjustment provides a simplified decision rule that reduces computational complexity compared to exhaustive interference analysis, while still achieving effective interference reduction through adaptive link selection.
