Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate light emission and reception assemblies are used to achieve dual-path transmission, then transmission rate and wavelength division capability are improved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines multiple light emission assemblies and light reception assemblies into a single integrated optical transceiver component. This integration allows dual-path transmission (1270nm and 1490nm wavelengths) to be achieved within one compact device, reducing the number of separate components while maintaining high transmission rates and wavelength division capabilities
Solution Approach 2:
The optical transceiver component is designed to perform multiple functions simultaneously: it can emit and receive light at different wavelengths (1270nm and 1490nm) through different incident and reception light ports, enabling both upstream and downstream communication paths within a single universal device
2Adaptability or versatility
If multiple separate light emission and reception assemblies are used to achieve dual-path transmission, then wavelength division capability is improved, but the space occupied increases
Solution Approach 1:
The patent merges multiple optical assemblies into one integrated component that handles both 1270nm and 1490nm wavelengths. The single optical transceiver component contains all necessary emission and reception assemblies, reducing the overall space occupied while maintaining full wavelength division capability for dual-path transmission
3Ease of manufacture
If conventional optical module design is used, then manufacturing simplicity is maintained, but coupling efficiency and insertion loss performance are insufficient
Solution Approach 1:
The patent applies local quality optimization by using precise lens configurations and filter sheets at specific locations within the optical paths. The lens assemblies are carefully positioned to optimize coupling between the light sources and fiber adapter, while filter sheets are placed to selectively transmit or block specific wavelengths, thereby improving coupling efficiency and reducing insertion loss without complicating the overall manufacturing process
