Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data frames and control frames are transmitted with strict synchronization and association management, then communication reliability is improved, but transmission delay increases
Solution Approach 1:
The patent segments the transmission process by separating data frame transmission from control frame transmission. Multiple data frames are transmitted in a burst without requiring intermediate control frame acknowledgments, and control frames are transmitted separately after the data burst. This segmentation eliminates the need for strict synchronization between individual data and control frames, reducing transmission delay while maintaining reliability through post-burst control frame verification.
Solution Approach 2:
The patent applies preliminary action by transmitting a sequence of data frames in advance without waiting for control frame acknowledgments after each frame. The transmitter sends multiple data frames proactively, and only afterward transmits control frames to manage acknowledgments. This preliminary data transmission approach eliminates waiting delays while maintaining reliability through subsequent control frame management.
2Reliability
If multiple transmissions are managed and synchronized strictly, then network performance is improved, but transmission speed decreases
Solution Approach 1:
The patent segments the transmission workflow into a data phase and a control phase. During the data phase, multiple data frames are transmitted rapidly without intermediate control interventions. The control phase follows afterward to manage acknowledgments. This segmentation allows high-speed data transmission while maintaining network performance through structured control frame management.
Solution Approach 2:
The patent enables continuous transmission of multiple data frames without interruption by control frame exchanges. The transmitter maintains continuous useful action by sending data frames in an unbroken sequence, eliminating idle waiting periods. Control frames are transmitted continuously after the data burst to ensure reliable acknowledgment management, thus maintaining both speed and network performance.
3Stability of the object's composition
If data frames are associated with control frames in traditional manner, then communication orderliness is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent segments the frame association process by decoupling data frame transmission from control frame association. Data frames are transmitted in a continuous burst without real-time control frame pairing, and control frames are associated with the entire data burst afterward. This segmentation maintains communication orderliness through structured post-burst control while dramatically improving transmission efficiency by eliminating per-frame association overhead.
Solution Approach 2:
The patent applies preliminary action by completing the entire data frame transmission sequence before initiating control frame association. The transmitter preliminarily sends all data frames without interruption, and only afterward establishes control frame associations for acknowledgment management. This preliminary data transmission maintains orderliness through structured control while improving efficiency by eliminating intermediate association delays.
