Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical components and electronic components are integrated on the circuit board, then the functionality and density of the optical communication system is improved, but the alignment precision between optical fibers and optical components deteriorates due to mechanical assemblies
Solution Approach 1:
The invention divides the alignment mechanism into separate functional elements: guide pins for horizontal alignment, guide holes for vertical alignment, and a fixing block for securing the optical fiber. This segmentation allows each element to specialize in one alignment dimension, achieving precise overall alignment while maintaining modular integration with electronic components on the circuit board.
Solution Approach 2:
The fixing block serves as an intermediary component between the optical fiber and the optical component housing. It contains guide pins and guide holes that mediate the alignment process, ensuring that the optical fiber is precisely positioned relative to the optical component while allowing the entire assembly to be integrated with electronic components on the circuit board.
2Manufacturing precision
If guide pins and guide holes are used for alignment, then the alignment precision is improved, but the assembly complexity increases
Solution Approach 1:
The invention merges the guide pins and guide holes into a single integrated fixing block component. This combining approach allows both horizontal and vertical alignment functions to be achieved through one unified structure rather than separate alignment mechanisms, reducing assembly complexity while maintaining precision. The fixing block is secured to the housing in a single operation, simplifying the overall assembly process.
