Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical fiber-based modules or waveguide-based modules are mounted in a conventional cartridge, then module functionality is expanded, but good optical coupling between collimators cannot be achieved
Solution Approach 1:
The invention introduces an alignment mechanism that enables dynamic adjustment of the third collimator's position and orientation. This allows the collimator to be precisely aligned with the first and second collimators during assembly, achieving good optical coupling while maintaining the ability to mount various optical fiber-based or waveguide-based modules in the cartridge
Solution Approach 2:
The invention introduces a third collimator as an intermediary optical component within the cartridge. This third collimator serves as a mediator that facilitates optical coupling between the optical fiber-based module and the external optical fibers, enabling both expanded functionality and precise optical alignment
2Adaptability or versatility
If conventional optical functional device cartridge modules are used, then bulk optical devices can be accommodated, but optical amplification cannot be performed
Solution Approach 1:
The invention designs the cartridge structure with universal compatibility to accommodate different types of optical functional objects, including optical fiber-based modules, waveguide-based modules, and bulk optical devices. The standardized interface and alignment mechanism allow the same cartridge structure to support multiple functions, including optical amplification, without requiring separate specialized designs for each device type
