Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Wireless USB interface is used for data transmission, then wireless communication capability is achieved, but data transfer efficiency and throughput are reduced due to overhead from transfer instructions and command packets
Solution Approach 1:
The patent segments the data transmission process by introducing virtual pipes that divide the wireless communication channel into multiple independent data paths. Each virtual pipe handles specific data streams separately, allowing parallel processing and reducing the overhead impact from transfer instructions and command packets. This segmentation enables more efficient utilization of the wireless interface by minimizing protocol overhead per data stream.
2Adaptability or versatility
If traditional USB protocol overhead is used in Wireless USB, then protocol compatibility is maintained, but throughput is limited compared to wired USB connections
Solution Approach 1:
The patent introduces virtual pipes as an intermediary layer between the USB protocol stack and the physical wireless interface. This intermediary abstracts and optimizes the data transmission path, reducing the impact of traditional USB protocol overhead while maintaining compatibility. The virtual pipes manage data flow more efficiently by batching transmissions and reducing the frequency of transfer instructions, thereby increasing throughput without sacrificing protocol compatibility.
3Productivity
If dynamic endpoint binding is implemented in wire adapter, then data path efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic endpoint binding in the wire adapter, allowing endpoints to be flexibly assigned and reconfigured based on current data transmission requirements. This dynamic allocation optimizes data path efficiency by matching endpoint capabilities with data stream characteristics in real-time. The system automatically manages endpoint configurations, reducing the need for manual intervention while maximizing throughput and data path utilization.
