Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional AUX channel transactions are used over wireless air interface, then control plane operations can be performed, but wireless bandwidth is wasted due to overhead from individual small data transfers
Solution Approach 1:
The patent merges multiple individual AUX channel transactions into a single consolidated data transfer over the wireless air interface. Instead of transmitting separate packets for each control plane operation, the system combines multiple transactions into one efficient data stream, reducing wireless bandwidth overhead and improving overall transmission efficiency.
Solution Approach 2:
The patent implements a two-tier packetization system where data is segmented into main link packets and AUX channel packets. This segmentation allows efficient handling of different data types: bulk data transfers use the main link while control plane operations use the AUX channel, optimizing bandwidth utilization for each transaction type.
2Loss of time
If AUX transactions are performed individually over wireless link, then control operations can be completed, but transmission time is increased due to repeated handshakes and protocol overhead
Solution Approach 1:
The patent performs preliminary actions by establishing the wireless connection and performing initial handshakes before actual data transfers. The system prepares the communication channel in advance, so that subsequent control plane operations can proceed more efficiently without repeated connection setup overhead.
Solution Approach 2:
The patent maintains continuous useful action by keeping the wireless connection established and active during control plane operations. Instead of repeatedly establishing and tearing down connections, the system maintains a continuous data stream that carries both main link and AUX channel transactions, reducing idle time and protocol overhead.
3Adaptability or versatility
If wireless air interface is used for DisplayPort connection, then device mobility and flexibility are improved, but bandwidth efficiency deteriorates due to lack of optimized packetization for wireless medium
Solution Approach 1:
The patent changes the packetization parameters to optimize wireless bandwidth efficiency. By implementing a two-tier system with different packet sizes and structures for main link and AUX channel transactions, the system adapts the data transmission parameters to match the characteristics of the wireless medium, improving overall bandwidth efficiency while maintaining device flexibility.
