Engineering Contradiction Analysis
1Productivity
If electrical signals are used for interconnect in electronic chip packages, then the system is simple and compatible with existing electronics, but the input/output capacity is insufficient for high-capacity processing chips
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission for interconnect purposes. Optical interfaces use light instead of electrical signals to transmit data between processing chips, enabling much higher input/output capacity per unit area while maintaining system functionality
Solution Approach 2:
The optical interface system serves multiple functions: it provides high-capacity data transmission, enables synchronization between chips, and supports both unidirectional and bidirectional communication modes, making it a versatile solution for various interconnect requirements
2Productivity
If optical signals are used to increase input/output capacity, then the data transmission capacity increases significantly, but the device complexity and interface requirements increase
Solution Approach 1:
The optical interface system is divided into separate functional modules: optical signal generation, modulation, transmission, and detection. This segmentation allows each component to be optimized independently and simplifies the overall system design and maintenance
Solution Approach 2:
The patent introduces optical coupling mechanisms and interface standards as intermediaries between electrical electronic systems and optical transmission systems. These intermediaries enable seamless integration and simplify the complexity of direct optical-electrical conversion
