Engineering Contradiction Analysis
1Reliability
If light-emitting component and photoelectric conversion component are combined using different manufacturing processes, then system functionality is achieved, but system redundancy and complexity increase
Solution Approach 1:
The patent merges the light-emitting component and photoelectric conversion component into a single integrated device structure, where both components share common substrates and manufacturing processes. This integration eliminates the need for separate manufacturing processes and reduces system redundancy while maintaining full functionality of both components.
2Ease of manufacture
If separate components are used for light emission and photoelectric conversion, then manufacturing flexibility is maintained, but system miniaturization is limited
Solution Approach 1:
The patent combines both components within a single device footprint, utilizing shared substrates and integrated fabrication processes. This merging approach enables significant system miniaturization while preserving manufacturing flexibility through the use of standard semiconductor manufacturing techniques that can produce both components simultaneously.
3Device complexity
If one-way communication system is implemented, then system simplicity is maintained, but communication efficiency and flexibility are reduced
Solution Approach 1:
The integrated device structure enables the system to perform both transmission and reception functions, transforming a one-way communication system into a bidirectional communication system. This multi-functionality allows the same device to act as both transmitter and receiver, significantly improving communication efficiency and flexibility without substantially increasing system complexity.
