Engineering Contradiction Analysis
1Adaptability or versatility
If multiple domain conversions between electrical and optical domains are performed, then data transport functionality is achieved, but system complexity increases
Solution Approach 1:
The patent combines multiple domain conversion functions (electrical-to-optical and optical-to-electrical conversions) into a single integrated pluggable module. This module includes both transmitter and receiver components that can perform bidirectional conversions without requiring separate external devices, thereby reducing system complexity while maintaining full data transport functionality.
Solution Approach 2:
The pluggable module is designed as a universal device that can perform multiple functions: electrical-to-optical conversion, optical-to-electrical conversion, and bidirectional data transport. This multi-functional design eliminates the need for separate specialized devices for each function, reducing overall system complexity.
2Adaptability or versatility
If multiple domain conversions are performed, then data transport is enabled, but space occupation increases
Solution Approach 1:
The patent integrates multiple conversion functions into a single compact pluggable module that occupies minimal space. By combining transmitter, receiver, and control circuits into one module, the physical space required is significantly reduced compared to using separate external devices for each function.
Solution Approach 2:
The pluggable module employs a nested structure where the receiver unit is integrated within the transmitter unit housing. The control circuit is embedded within the module, and all components are nested together in a compact arrangement that minimizes space occupation while enabling multiple domain conversions.
3Adaptability or versatility
If multiple domain conversions are performed, then data transport functionality is achieved, but power consumption increases
Solution Approach 1:
The patent combines multiple domain conversion operations into a single integrated module, reducing the total power consumption compared to using separate external devices. The shared control circuit and integrated architecture minimize redundant power usage while maintaining full bidirectional conversion capability.
Solution Approach 2:
The pluggable module includes an integrated control circuit that automatically manages the domain conversion operations without requiring external control devices. This self-service capability reduces the power consumption associated with external control systems while maintaining full functionality.
4Device complexity
If traffic management functionality is integrated into the pluggable module, then system complexity is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent divides the traffic management functionality into discrete, modular components within the pluggable module. The transmitter, receiver, and control circuits are segmented into separate functional units that can be manufactured independently and then assembled, reducing overall manufacturing complexity while enabling integrated traffic management.
Solution Approach 2:
The pluggable module is designed as a universal platform that can perform multiple traffic management functions through a single integrated design. This multi-functionality is achieved through standardized interfaces and modular components that can be configured for different applications, simplifying manufacturing compared to producing multiple specialized devices.
