Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional optical fiber connector structures are used, then the assembly process becomes complex and time-consuming, but the connection stability and alignment precision cannot be guaranteed
Solution Approach 1:
The connector is divided into distinct functional modules: a holding member with first and second holding portions for separate fiber segments, a securing cover for fixed encasement, and a ferrule unit for precise alignment. This segmentation allows each component to be optimized independently while simplifying the overall assembly process through modular construction.
Solution Approach 2:
The holding member is pre-formed with specific groove structures (first groove portion, second groove portion, third groove portion) that are designed to receive and position the optical fiber at precise locations before final assembly. The positioning holes and protruding blocks are pre-configured to ensure accurate alignment, eliminating the need for complex adjustment during assembly.
2Productivity
If loose optical fiber connections are allowed, then the assembly process is simpler, but light signal transmission efficiency decreases
Solution Approach 1:
The holding member features differentiated groove structures at different locations: the first groove portion receives the cladding layer, the second groove portion positions the fiber core, and the third groove portion provides additional support. Each groove has specific dimensional characteristics optimized for its local function, ensuring precise fiber positioning and alignment while maintaining assembly efficiency.
Solution Approach 2:
The securing cover automatically secures the optical fiber through its encasement structure, and the holding member's groove system self-aligns the fiber components during assembly. The positioning holes and protruding blocks create a self-positioning mechanism that ensures accurate alignment without requiring complex external tools or adjustment procedures.
3Manufacturing precision
If precise alignment structures are added to ensure connection accuracy, then transmission efficiency improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The holding member integrates multiple alignment functions into a single component: it contains the optical fiber, provides positioning through grooves, and features positioning holes for alignment. The ferrule unit combines the alignment reference structure with the connection interface. This merging reduces the number of separate precision components needed, simplifying manufacturing while maintaining high alignment precision.
Solution Approach 2:
The holding member is pre-formed with accurately positioned grooves and positioning holes during manufacturing. These features are created in advance with precise dimensional relationships, ensuring that when the fiber is assembled, the alignment is automatically achieved without requiring post-assembly adjustment or complex machining operations.
