Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transmitted using fixed fragmentation levels in existing wireless communication standards, then device compatibility is maintained, but communication efficiency deteriorates in high-density environments
Solution Approach 1:
The patent implements dynamic fragmentation level negotiation between transmitter and receiver during the ADDBA setup procedure. Instead of using fixed fragmentation levels, the system allows both ends to exchange capability information and agree on optimal fragmentation levels adaptively. This dynamic adjustment enables the system to optimize communication efficiency for different transmission scenarios while maintaining compatibility through standardized negotiation protocols.
Solution Approach 2:
The patent changes the fragmentation level parameter from a fixed value to a negotiable variable. By introducing fragmentation level indication fields in ADDBA request and response frames, the system enables both transmitter and receiver to indicate their supported fragmentation levels and agree on the actual level to use. This parameter change allows flexible adaptation to different transmission conditions without requiring complex device modifications.
2Productivity
If dynamic fragmentation negotiation is implemented, then communication efficiency improves in high-density environments, but protocol complexity increases
Solution Approach 1:
The patent performs fragmentation level negotiation in advance during the ADDBA setup procedure, before actual data transmission begins. Both transmitter and receiver exchange their fragmentation level capabilities and agree on the levels to use for subsequent transmissions. This preliminary action eliminates the need for real-time adjustments during data transmission, simplifying the overall protocol while improving efficiency.
Solution Approach 2:
The patent implements feedback mechanisms where the receiver provides block acknowledgments that include information about successfully received fragments. This feedback allows the transmitter to understand the actual reception conditions and adjust future transmissions accordingly. The feedback loop enables continuous optimization of transmission efficiency without requiring complex real-time control mechanisms.
