Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transceiver resources are statically allocated to each link, then device complexity is reduced and operation is simplified, but adaptability to dynamic wireless conditions deteriorates and throughput is limited
Solution Approach 1:
The patent implements dynamic transceiver configuration where the receiving capability is switched between links based on real-time transmission opportunities. The second link's receiving capability is dynamically allocated to the first link during TXOPs, enabling the system to adapt to varying wireless conditions and maximize throughput while maintaining manageable complexity through controlled dynamic behavior.
2Adaptability or versatility
If transceiver resources are dynamically switched between links, then adaptability to wireless conditions is improved, but device complexity increases and operation becomes more difficult
Solution Approach 1:
The patent implements dynamic transceiver configuration where the receiving capability is switched between links based on real-time transmission opportunities. The second link's receiving capability is dynamically allocated to the first link during TXOPs, enabling the system to adapt to varying wireless conditions and maximize throughput while maintaining manageable complexity through controlled dynamic behavior.
Solution Approach 2:
The patent employs feedback mechanisms where the transmitting device announces TXOP information to the receiving device, which then switches its receiving capability accordingly. This feedback loop ensures that dynamic resource allocation is coordinated between devices, reducing operational complexity while maintaining high adaptability to changing wireless conditions.
3Productivity
If receiving capability is switched to support more spatial streams, then throughput is improved, but reliability of transmission may deteriorate due to potential switching failures
Solution Approach 1:
The patent performs preliminary switching of the receiving capability before data transmission begins. The receiving device switches its capability in advance based on announced TXOP information, ensuring that the switching is completed and stable before actual data transmission starts. This preliminary action reduces the risk of transmission failures due to switching issues while enabling higher throughput through increased spatial streams.
4Productivity
If transmission resources are allocated to increase spatial streams, then throughput is improved, but loss of time for resource negotiation and switching increases
Solution Approach 1:
The patent performs preliminary switching of the receiving capability before data transmission begins. The receiving device switches its capability in advance based on announced TXOP information, ensuring that the switching is completed and stable before actual data transmission starts. This preliminary action reduces the risk of transmission failures due to switching issues while enabling higher throughput through increased spatial streams.
Solution Approach 2:
The patent enables continuous data transmission by pre-configuring the receiving capability before TXOPs. Once the receiving device switches its capability in advance, it can continuously receive data frames without interruption or additional negotiation during the transmission period, maximizing the utilization of allocated resources and reducing time loss.
