Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multi-core fiber is rotationally aligned by twisting between holding portion and end surface, then rotational alignment is achieved, but rotational torque is generated causing core position fluctuation and deviation
Solution Approach 1:
The patent applies preliminary action by fixing the multi-core fiber to the connector before performing rotational alignment. This preliminary fixation prevents the fiber from moving or twisting during the alignment process, thereby eliminating rotational torque and preventing core position fluctuation. The fiber is secured in a fixed state prior to alignment operations, ensuring stable core positioning throughout the manufacturing process.
2Stability of the object's composition
If multi-core fiber is collectively bonded after alignment, then structural stability is improved, but core position deviation occurs during the bonding process
Solution Approach 1:
The patent applies preliminary action by performing rotational alignment and fixation before collective bonding. The fiber is first secured to the connector in a fixed state, maintaining precise core positioning, and only after this preliminary fixation is complete is the collective bonding performed. This sequence ensures that the fiber arrangement remains stable and precise throughout the entire process.
3Ease of operation
If rotational alignment is performed without fixation, then alignment flexibility is maintained, but coupling loss increases due to core position fluctuation
Solution Approach 1:
The patent applies preliminary action by fixing the multi-core fiber to the connector before performing rotational alignment. This preliminary fixation maintains the fiber in a stable, fixed state during alignment operations, preventing core position fluctuation and minimizing coupling loss. The fixation ensures reliable core positioning while still allowing the necessary alignment adjustments to be made in a controlled manner.
