Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static load distribution configuration is used for packet-switched data transmission between seaside transceivers and landside transceivers, then device complexity is reduced and ease of operation is improved, but adaptability to changing transmission conditions deteriorates and transmission efficiency is reduced
Solution Approach 1:
The patent implements dynamic load distribution by continuously monitoring transmission conditions (signal strength, error rates, channel availability) and automatically adjusting the allocation of data packets across multiple air interfaces. The system transitions from static configuration to dynamic reconfiguration, allowing load distribution ratios to change in real-time based on current channel quality, thereby resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where transmission performance metrics are continuously measured and fed back to the load distribution controller. This feedback loop enables the system to automatically adjust load distribution decisions based on actual transmission conditions, achieving adaptability without requiring complex manual configuration while maintaining optimal performance.
2Reliability
If multiple air interfaces are used for data transmission, then transmission reliability and productivity are improved, but device complexity and difficulty of control increase
Solution Approach 1:
The patent merges the management of multiple air interfaces (terrestrial cellular and satellite communications) under a unified load distribution controller that handles packet routing, interface selection, and transmission management. By consolidating control functions and presenting a unified interface to upper layers, the system achieves high transmission reliability through diverse interfaces while minimizing the perceived complexity through integrated management.
Solution Approach 2:
The load distribution controller is designed with multi-functional capabilities to manage different types of air interfaces (terrestrial and satellite) using common protocols and procedures. This universal approach allows the system to leverage multiple communication interfaces for improved reliability while avoiding the complexity of separate management systems for each interface type.
3Productivity
If dynamic load balancing is implemented between seaside transceivers, then transmission efficiency and adaptability are improved, but processing time and computational requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing monitoring of transmission conditions and pre-calculating load distribution strategies based on predicted channel behavior. By preparing load distribution decisions in advance based on current conditions and historical patterns, the system can quickly adapt to changes without excessive processing delays, thus improving transmission efficiency while minimizing decision-making time.
