Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wireless communication links are used for data transmission, then data transmission efficiency is improved, but link instability occurs
Solution Approach 1:
The patent implements dynamic link selection by detecting link states (establishing, established, lost) and adapting the transmission path in real-time. The system transitions from static single-link transmission to dynamic multi-link selection based on current network conditions, resolving the contradiction between utilizing multiple links for efficiency and maintaining stability by avoiding unstable links.
Solution Approach 2:
The patent employs feedback mechanisms through link state detection and packet acknowledgment. The transmitting device monitors whether packets are successfully delivered and adjusts link selection based on feedback about link quality. This feedback loop enables the system to identify and avoid unstable links while utilizing reliable ones, balancing efficiency and reliability.
2Quantity of substance
If wireless link resources are shared competitively in the same area, then network capacity is increased, but data transmission reliability deteriorates
Solution Approach 1:
The patent segments data transmission into multiple independent links with distinct characteristics. By dividing the transmission task across different wireless links (e.g., Wi-Fi, cellular) rather than sharing a single contested resource, the system maintains network capacity while reducing competition-induced reliability issues on any single link.
3Productivity
If link state detection and dynamic selection is implemented, then transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements partial link state detection rather than comprehensive monitoring of all possible parameters. The system detects basic link states (establishing, established, lost) sufficient for making transmission decisions, avoiding the complexity of exhaustive link analysis while maintaining adequate transmission efficiency.
