Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If parallel data is transmitted between boards using a parallel cable, then data transmission can be performed, but transmission rate is reduced and crosstalk phenomenon occurs
Solution Approach 1:
The patent replaces the mechanical electrical signal transmission system with an optical signal transmission system. By converting parallel data into optical signals for serial transmission, the system eliminates crosstalk between signal lines while maintaining high transmission rates, directly resolving the contradiction between transmission speed and signal interference.
Solution Approach 2:
The patent segments parallel data into multiple time-divided serial data streams, each transmitted separately through optical channels. This segmentation allows simultaneous transmission of multiple data lines without interference, improving transmission rate while eliminating crosstalk by isolating each data stream in time and space.
2Productivity
If parallel data is converted to serial data using a header identifier, then data can be transmitted serially, but delay time occurs during data restoration
Solution Approach 1:
The patent changes the identification parameter from header-based code analysis to pulse width-based timing identification. By encoding data line identifiers in the pulse width characteristics of optical signals rather than using header codes, the system eliminates the need for complex code analysis during restoration, thereby reducing delay time while maintaining transmission efficiency.
Solution Approach 2:
The patent performs preliminary encoding of data line identifiers into pulse width characteristics before transmission. This preliminary action embeds the identification information in the temporal structure of the optical signals themselves, allowing the receiving end to rapidly identify and restore data lines without time-consuming header analysis, thus reducing restoration delay.
