Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an extender simultaneously supports USB and Displayport devices with separate optical transceiver modules, then transmission capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling a single optical transceiver module to handle both USB and Displayport auxiliary signals through protocol identification and conversion. The system receives auxiliary signals from either USB or Displayport interfaces, identifies the protocol type, and processes them through a unified conversion path using the same optical transceiver infrastructure, thereby eliminating the need for separate modules for each interface type.
Solution Approach 2:
The patent introduces an intermediary conversion mechanism that mediates between different interface protocols (USB and Displayport auxiliary signals) and the optical transceiver module. This intermediary layer performs protocol identification, signal conversion, and packet formatting, allowing a single optical transceiver to interface with multiple protocol types without requiring dedicated modules for each protocol.

If multiple connection lines are used to improve transmission speed for USB and Displayport, then transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using a single optical transceiver module to handle both USB and Displayport auxiliary signals. The system identifies the protocol type from the incoming auxiliary signal and processes it through a unified conversion pathway, allowing high-speed transmission for both interface types without requiring separate dedicated connection lines for each protocol.
