Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional optical path control methods are used to adjust light beam spacing, then light beam coupling into photoelectric detectors can be achieved, but the system volume and complexity increase
Solution Approach 1:
The patent combines the optical path control function and beam convergence function into a single integrated optical path control assembly. This assembly includes multiple wedge-shaped blocks arranged in parallel, where each wedge-shaped block controls a specific light beam. By merging these functions, the system reduces the number of separate components needed, thereby reducing overall system complexity while maintaining effective light beam coupling into photoelectric detectors
Solution Approach 2:
The optical path control assembly is segmented into multiple independent wedge-shaped blocks, with each block responsible for controlling a specific light beam. This segmentation allows for independent adjustment of each light beam's propagation direction and spacing, enabling precise control without requiring complex interconnected mechanisms, thus reducing overall system complexity while maintaining high coupling efficiency
2Adaptability or versatility
If light beam spacing is adjusted for different channel configurations, then adaptability to different optical communication devices is improved, but the system becomes more complex
Solution Approach 1:
The wedge-shaped blocks are designed to be movable along the optical axis, allowing dynamic adjustment of the light beam spacing. This dynamic capability enables the system to adapt to different channel spacing requirements (such as WDM configurations) without requiring a completely different optical path control structure, thereby improving versatility while maintaining relatively simple system architecture
Solution Approach 2:
The optical path control assembly with multiple wedge-shaped blocks serves multiple functions: it controls light beam spacing, adjusts propagation directions, and adapts to different channel configurations (such as 8-channel WDM). This multi-functionality is achieved through a single integrated assembly design, avoiding the need for multiple specialized components, thus improving adaptability without proportionally increasing system complexity
3Volume of moving object
If the size of optical modules is reduced for miniaturization, then integration performance improves, but optical path control precision becomes more difficult to maintain
Solution Approach 1:
The wedge-shaped blocks are arranged in parallel along the optical axis, utilizing the longitudinal dimension to control light beam spacing. This dimensional arrangement allows for effective optical path control within a compact transverse footprint, enabling miniaturization of the optical module while maintaining precise control over light beam propagation and spacing through the extended optical axis direction
