Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-route communication technique is adopted to transmit replicated data via different communication carriers, then communication reliability is improved, but communication delay increases when data generation speed exceeds transmission speed of certain carriers
Solution Approach 1:
The patent dynamically changes transmission parameters by selecting different communication interfaces based on real-time data generation speed and interface transmission speeds. When data generation speed exceeds the transmission speed of certain interfaces, the system adjusts by prioritizing faster interfaces and controlling replication quantity, thereby resolving the contradiction between reliability and delay.
2Productivity
If data is transmitted via multiple communication interfaces in parallel, then transmission speed is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic interface selection and data replication control based on real-time monitoring of data generation speed and interface transmission speeds. The processor dynamically determines the quantity of replicated data and selects appropriate communication interfaces, enabling the system to adapt to changing conditions without requiring all interfaces to operate simultaneously at full capacity, thus balancing productivity and complexity.
3Productivity
If replicated data quantity is increased to utilize multiple communication interfaces, then transmission efficiency is improved, but communication cost increases
Solution Approach 1:
The patent optimizes the quantity of replicated data based on the transmission speeds of different communication interfaces and the data generation speed. By calculating the appropriate replication quantity dynamically, the system transmits data efficiently using multiple interfaces only when necessary, avoiding unnecessary replication and transmission over slower or more costly interfaces, thus improving transmission efficiency while controlling communication cost.
