Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical duplex channels are used to reduce pin count, then the number of connector pins is reduced, but the transmission distance is limited
Solution Approach 1:
The patent introduces an optical signal as an intermediary medium to bridge the electrical connector and the remote device. The electrical duplex signal is converted to optical signal for long-distance transmission, and then converted back to electrical signal at the receiving end. This intermediary optical transmission enables extended transmission distance while maintaining electrical connector compatibility.
Solution Approach 2:
The patent replaces the electrical signal transmission mechanism with an optical signal transmission mechanism for the intermediate transmission medium. By substituting electrical signals with optical signals in the transmission path, the system overcomes the distance limitations of electrical duplex channels while maintaining the electrical connector interface.
2Device complexity
If electrical duplex channels are used, then pin count is reduced, but data transmission capability for high-resolution video is limited
Solution Approach 1:
The optical signal acts as an intermediary that enables high-bandwidth data transmission. The conversion from electrical duplex to optical signal allows the system to achieve the data transmission rates required for high-resolution video while still using a single electrical connector interface.
3Length of stationary object
If optical signals are used for long-distance transmission, then transmission distance is extended, but device complexity increases
Solution Approach 1:
The electrical connector serves multiple functions: it provides the electrical interface for short-distance communication and simultaneously serves as the interface for the optical conversion device. This multi-functionality reduces the need for separate connectors while enabling extended transmission capability.
