Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is transmitted through multiple heterogeneous access networks simultaneously, then content availability and service quality are improved, but content synchronization becomes difficult to maintain
Solution Approach 1:
The system performs preliminary actions by calculating delay latency values for each access network before content transmission begins. The content server pre-divides content into frames and determines the optimal transmission timing for each network based on their respective delay characteristics, ensuring synchronization is established in advance rather than attempting to correct it during transmission.
Solution Approach 2:
The content is segmented into discrete frames with synchronization frame counters assigned to each. This segmentation allows the system to track and control each frame's transmission independently across different access networks, making synchronization manageable by treating each frame as a separate unit that can be timed and coordinated individually.
2Productivity
If content is divided and transmitted through different access networks, then network resource utilization is improved, but transmission timing coordination becomes complex
Solution Approach 1:
The base station receives feedback from the terminal in the form of a response to the synchronization frame counter. This feedback mechanism allows the system to measure actual transmission delays and adjust timing calculations, creating a closed-loop control system that simplifies coordination by using real-world performance data to refine transmission scheduling.
Solution Approach 2:
The system changes the timing parameters of content transmission based on calculated delay latency values for each access network. By dynamically adjusting transmission timing parameters rather than using fixed schedules, the system adapts to the specific characteristics of each network, simplifying coordination while maximizing resource utilization.
3Manufacturing precision
If delay latency is calculated and transmission timing is adjusted for each terminal, then content synchronization accuracy is improved, but system processing complexity increases
Solution Approach 1:
The terminal actively participates in the synchronization process by responding to synchronization frame counters and providing feedback on reception timing. This self-service approach distributes the processing burden, as the terminal performs measurements and reports back, rather than requiring the server to continuously monitor and adjust every transmission in real-time.
