Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single Wi-Fi connection is used for data transmission, then the system complexity is low, but the data transmission efficiency is low
Solution Approach 1:
The patent segments the data transmission path into multiple independent Wi-Fi connections (first Wi-Fi connection and second Wi-Fi connection), each handled by separate Wi-Fi modules. This allows parallel data transmission through multiple paths, improving overall transmission efficiency while maintaining manageable complexity through modular architecture
Solution Approach 2:
The patent merges multiple Wi-Fi connections into a unified MPTCP connection that aggregates bandwidth from both connections. This combining approach enables the system to leverage the cumulative capacity of multiple wireless interfaces, significantly enhancing data transmission efficiency compared to single-connection approaches
2Speed
If multiple Wi-Fi connections are used for data transmission, then the data transmission rate is improved, but the device complexity increases
Solution Approach 1:
The patent implements MPTCP (Multipath TCP) which provides universal multi-functionality by enabling a single TCP connection to utilize multiple underlying transport paths. This allows the system to dynamically aggregate bandwidth from multiple Wi-Fi connections while maintaining a unified interface for applications, improving transmission rate without proportionally increasing complexity
Solution Approach 2:
The patent introduces the MPTCP protocol as an intermediary layer between the application layer and the individual Wi-Fi connections. This mediator handles the complexity of managing multiple connections, performing path selection, load balancing, and error recovery, thereby enabling high-speed transmission while shielding applications from the underlying complexity
3Reliability
If redundant scheduling strategies are implemented, then the reliability of data transmission is improved, but the system overhead increases
Solution Approach 1:
The patent implements redundant scheduling strategies that prepare multiple transmission paths in advance before failures occur. By maintaining ready-to-use alternative Wi-Fi connections and pre-configuring failover mechanisms, the system ensures continuous reliable transmission while managing overhead through proactive rather than reactive measures
