Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed relay stations are deployed to overcome shadow fading effects, then data transmission reliability is improved, but network deployment cost increases and disposition flexibility deteriorates
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed relay stations with mobile nodes that can dynamically change their positions. The mobile node relay apparatus receives location information from first and second mobile nodes, determines optimal relay positions based on real-time locations, and dynamically establishes relay connections. This dynamic positioning capability allows the system to adapt to changing network conditions and overcome shadow fading effects without being constrained by fixed infrastructure, thereby improving reliability while maintaining disposition flexibility.
2Reliability
If fixed relay stations are deployed to relay data between mobile nodes, then data transmission reliability is improved, but device complexity and deployment cost increase
Solution Approach 1:
The patent applies the self-service principle by enabling mobile nodes to perform relay functions autonomously without requiring external fixed relay station infrastructure. The mobile node relay apparatus automatically receives location information from other mobile nodes, independently determines relay positions and paths, and establishes relay connections without human intervention or complex centralized control. This self-organizing capability simplifies the overall system architecture by eliminating the need for complex fixed relay station infrastructure while maintaining reliable data transmission between mobile nodes.
3Reliability
If fixed relay stations are used to transmit data, then shadow fading effects are mitigated, but the system becomes vulnerable to external factors like movable vehicles obstructing relaying
Solution Approach 1:
The patent applies the dynamics principle to counteract the vulnerability to external obstructions by enabling relay nodes to dynamically reposition themselves. When a fixed relay station is blocked by a movable vehicle or other external factors, the mobile node relay apparatus can receive location information from affected nodes and dynamically establish new relay paths through different spatial positions. This dynamic adaptability allows the system to overcome transient obstructions that would permanently block fixed relay stations, thereby maintaining data transmission reliability while reducing vulnerability to external factors.
