Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one network is selected for data transmission, then device complexity is reduced, but productivity decreases due to rapid load factor increase on single network
Solution Approach 1:
The patent divides data into multiple partial data segments and transmits them through different access networks simultaneously. The transmitting device segments the original data into first partial data and second partial data, sending them over first and second access networks respectively. This segmentation allows parallel transmission across multiple networks, improving overall data transmission efficiency while distributing network load.
2Productivity
If data is transmitted through multiple networks simultaneously, then productivity improves, but device complexity increases due to need for partial data selection and transmission rate adjustment
Solution Approach 1:
The patent implements a feedback mechanism where the transmitting device measures transmission state information including data transmission time intervals and data reception time intervals. Based on this feedback, the device dynamically adjusts transmission rates for partial data on different networks. The controller monitors network conditions and modifies transmission parameters in real-time to optimize performance while managing complexity.
Solution Approach 2:
The patent employs dynamic transmission rate adjustment based on real-time network conditions. The transmitting device varies transmission rates for partial data across different access networks according to measured transmission states. This dynamic adaptation allows the system to respond to changing network conditions, optimizing productivity while managing complexity through intelligent control.
3Device complexity
If transmission rate is fixed, then device complexity is reduced, but productivity decreases due to inability to adapt to varying network states
Solution Approach 1:
The patent changes transmission rate parameters dynamically based on measured network states. The transmitting device adjusts transmission rates for partial data on different access networks according to transmission state information including time intervals and network conditions. This parameter adaptation enables the system to optimize productivity for varying network states while maintaining manageable complexity through systematic control.
