Engineering Contradiction Analysis
1Productivity
If fixed quota bandwidth configuration is used for data transmission, then bandwidth allocation is simple and stable, but bandwidth utilization efficiency deteriorates due to mismatch between actual data requirements and allocated bandwidth
Solution Approach 1:
The patent implements dynamic bandwidth allocation by allowing the reception device to send requirement information indicating needed bandwidth, and the transmission device to adjust transmission bandwidth accordingly. This transforms the static fixed quota system into a dynamic system that adapts to actual data transmission needs, resolving the contradiction between simple allocation and high utilization efficiency.
Solution Approach 2:
The patent establishes a feedback mechanism where the reception device communicates its bandwidth requirements back to the transmission device through requirement information. This feedback loop enables the transmission device to adjust bandwidth allocation based on actual needs, improving utilization efficiency while maintaining manageable complexity through automated feedback-driven adjustment.
2Reliability
If maximum bandwidth requirement of all application scenarios is adopted, then all data types can be transmitted without bandwidth limitation, but bandwidth waste increases when actual transmitted data is much lower than total transmission bandwidth
Solution Approach 1:
The patent enables the transmission bandwidth to dynamically adjust between minimum and maximum requirements based on actual transmission needs. Rather than always allocating maximum bandwidth, the system adapts to the current data requirements, ensuring reliable transmission when needed while minimizing waste during low-traffic periods.
Solution Approach 2:
The patent changes the bandwidth parameter from a fixed maximum value to a variable value that adjusts according to requirement information from the reception device. This parameter change allows the system to maintain transmission reliability by allocating sufficient bandwidth when needed, while reducing bandwidth allocation to minimize waste during normal operation.
3Productivity
If dynamic bandwidth allocation according to requirement information is implemented, then bandwidth utilization efficiency is optimized, but system complexity increases due to additional communication and control mechanisms
Solution Approach 1:
The patent uses feedback mechanism where reception device sends requirement information and transmission device responds with attribute information and adjusted bandwidth allocation. This feedback-driven approach automates the bandwidth optimization process, achieving high utilization efficiency while managing complexity through standardized feedback loops rather than complex centralized control.
Solution Approach 2:
The patent enables the reception device to self-determine its bandwidth requirements and communicate them to the transmission device. The transmission device then autonomously adjusts bandwidth allocation based on this information. This self-service mechanism distributes the intelligence for bandwidth management, reducing overall system complexity compared to centralized control while achieving optimal utilization.
