Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a QSFP-to-SFP adapter is used to enable optical transceiver functionality, then adaptability and versatility are improved, but signal integrity deteriorates and electromagnetic interference increases
Solution Approach 1:
The patent removes the QSFP-to-SFP adapter from the optical transceiver module, extracting the problematic intermediate component that caused signal integrity degradation and electromagnetic interference. The optical source is directly coupled to the optical connector without requiring an adapter, thereby eliminating the harmful effects while maintaining adaptability through direct integration.
2Ease of operation
If a QSFP-to-SFP adapter is used to facilitate optical connection, then ease of operation is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The adapter is removed from the system, eliminating the thermal barrier it created between the optical source and the heatsink. This direct coupling allows heat to dissipate more efficiently from the optical source to the heatsink, improving thermal management while maintaining operational simplicity through integrated design.
3Device complexity
If traditional mechanical adapters are used for optical transceivers, then device complexity is reduced, but electromagnetic interference increases
Solution Approach 1:
The patent replaces the mechanical adapter system with a directly integrated optical connection. The optical source is mounted on the PCB and directly coupled to the optical connector, eliminating the mechanical adapter interfaces that generated electromagnetic interference. This substitution maintains simplicity while reducing harmful electromagnetic effects.
