Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission is performed without fragmentation, then transmission speed is improved, but TXOP limit compliance deteriorates
Solution Approach 1:
The patent applies segmentation by dividing a large data packet into multiple smaller fragments before transmission. Each fragment is transmitted separately within the TXOP limit, allowing the system to maintain high transmission speeds while complying with the maximum transmission opportunity duration. The transmitter divides the original data into fragment units that can be sent in sequential batches, ensuring each batch fits within the TXOP constraint.
Solution Approach 2:
The patent implements dynamic fragmentation where the fragment size and number are adjusted based on real-time channel conditions, TXOP limit requirements, and data priority. The system dynamically determines the optimal fragmentation level to maximize transmission speed while ensuring compliance with TXOP limits, adapting to varying network conditions rather than using fixed fragmentation parameters.
2Productivity
If dynamic fragmentation is applied, then TXOP limit compliance is improved, but device complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the receiver sends acknowledgment information about successfully received fragments back to the transmitter. Based on this feedback, the transmitter dynamically adjusts subsequent fragmentation strategies, fragment sizes, and retransmission decisions. This feedback loop enables the system to achieve TXOP compliance while managing complexity through adaptive rather than purely predetermined fragmentation logic.
Solution Approach 2:
The system implements self-service through automatic fragmentation and reassembly processes that occur without manual intervention. The transmitter automatically divides data into appropriate fragments based on TXOP limits, and the receiver automatically reassembles received fragments into the original data. This self-service capability reduces the need for complex external control mechanisms while maintaining TXOP compliance.
3Reliability
If multiple fragments are transmitted, then data reliability is improved, but transmission time increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-organizing data into fragments before transmission begins. The fragmentation structure is established in advance based on expected TXOP limits and channel conditions, allowing the transmitter to efficiently send fragments without on-the-fly processing delays. This preliminary organization reduces overall transmission time while maintaining the reliability benefits of fragmented transmission.
Solution Approach 2:
The patent maintains continuity of useful action by overlapping fragment transmission with acknowledgment processing. While waiting for acknowledgments for previously sent fragments, the transmitter continues to send subsequent fragments without idle pauses. This continuous transmission approach minimizes the total transmission time while still achieving the reliability benefits of fragmented data transfer with error detection and retransmission capabilities.
