Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple optical fibers are used to transmit and receive data, then bandwidth capacity is increased, but hardware complexity and device complexity increase
Solution Approach 1:
The patent combines multiple optical signals with different polarizations onto a single optical fiber using polarization beam combiners. This merging approach allows multiple data channels to share one physical fiber, increasing bandwidth capacity while reducing the number of fibers needed, thereby decreasing hardware complexity
Solution Approach 2:
The patent utilizes the polarization dimension of light to encode multiple signals. By assigning different polarization states (horizontal, vertical, circular) to different data streams, the system can transmit multiple channels simultaneously over a single fiber, effectively adding a dimensional multiplexing capability that increases bandwidth without proportionally increasing hardware
2Productivity
If multiple optical fibers are used for transmission, then bandwidth demand is met, but power consumption increases
Solution Approach 1:
The patent merges multiple optical signals onto a single fiber using polarization multiplexing, which reduces the total number of fiber connections and associated optical components. This consolidation directly reduces power consumption by eliminating redundant transmitters, receivers, and fiber infrastructure while maintaining the required bandwidth capacity
3Productivity
If multiple fibers are used for optical reception, then signal capacity is increased, but the number of components and hardware complexity increase
Solution Approach 1:
The patent employs polarization beam combiners to merge multiple incoming optical signals with different polarizations onto a single fiber. This reduces the number of separate receivers and fiber connections needed, thereby decreasing the number of components and hardware complexity while preserving signal capacity
Solution Approach 2:
The polarization beam combiner serves multiple functions: it combines signals from different polarizations, acts as a signal splitter in reverse, and enables a single receiver to process multiple data channels. This multi-functionality reduces the overall component count while maintaining signal capacity
