Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If link aggregation is continuously performed without adaptive control, then the structure for transmitting data through multiple links is maintained, but interference between antennas increases and radio resource utilization becomes suboptimal
Solution Approach 1:
The patent implements adaptive link aggregation by dynamically adjusting the aggregation state based on real-time channel conditions. The processor monitors channel characteristics and data characteristics, then triggers or terminates link aggregation accordingly. This dynamic control allows the system to transition between aggregated and non-aggregated states, resolving the contradiction between maintaining stable link aggregation and reducing antenna interference.
2Device complexity
If link aggregation is triggered based on fixed thresholds, then the control logic is simple, but the system cannot adapt to varying data and channel conditions leading to wasted time and reduced channel access success
Solution Approach 1:
The patent changes the control parameters from fixed thresholds to dynamic evaluation based on channel characteristics and data characteristics. The processor evaluates multiple parameters including channel congestion levels, data size, data priority, and QoS requirements to determine whether to trigger link aggregation. This parameter-based adaptive approach increases productivity by optimizing channel access success while maintaining manageable complexity through structured evaluation criteria.
3Speed
If link aggregation is used to transmit data through multiple links, then transmission speed increases, but interference between antennas and suboptimal radio resource utilization occur
Solution Approach 1:
The patent implements feedback-based adaptive link aggregation where the processor continuously monitors channel characteristics and data characteristics, then adjusts the link aggregation state accordingly. The system evaluates the impact of link aggregation on transmission performance and resource utilization, terminating aggregation when interference or resource waste is detected. This feedback mechanism allows the system to maintain high transmission speed while minimizing radio resource waste through intelligent control.
