Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication technologies are used in high-density environments with multiple terminals, then communication coverage and connectivity are improved, but bandwidth utilization and transmission efficiency deteriorate
Solution Approach 1:
The patent segments the communication process by introducing trigger frames that divide uplink transmissions into distinct phases. The trigger frame mechanism segments the medium access control into trigger-based random access and traditional contention-based access, allowing efficient resource allocation in high-density environments while maintaining good bandwidth utilization
Solution Approach 2:
The patent applies preliminary action by having the access point send trigger frames before uplink transmissions. These trigger frames pre-allocate resource units and provide transmission parameters in advance, enabling terminals to transmit efficiently without contention or collision, thus improving bandwidth utilization while supporting multiple terminals
2Productivity
If trigger information is used to manage communication with multiple terminals, then transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The trigger frame structure serves multiple functions simultaneously: it allocates resource units, provides transmission parameters, identifies target terminals, and controls uplink access. This multi-functionality improves transmission efficiency while avoiding the need for separate control mechanisms, thereby limiting the increase in device complexity
Solution Approach 2:
The patent changes key communication parameters through the trigger frame mechanism, including resource unit allocation, modulation and coding schemes, and transmission timing. By centralizing parameter control in the trigger frame, the system achieves high transmission efficiency while keeping terminal complexity low, as terminals simply follow parameters provided by the access point
