Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fiber fusing splicer is used to couple two plastic fiber cables, then coupling reliability is improved, but device complexity and cost increase
Solution Approach 1:
The coupling device is divided into separate male and female coupling pieces, each with distinct functional features (guiding faces, fiber channels, detent bodies). This segmentation allows for simplified individual components that assemble together to achieve reliable coupling without requiring complex splicing equipment.
Solution Approach 2:
The coupling pieces act as intermediary components between two fiber cables, providing a mechanical interface that aligns and secures the cables. The detent bodies and guiding faces serve as intermediary features that ensure proper positioning and stable connection without direct cable-to-cable splicing.
2Manufacturing precision
If traditional fiber fusing splicer is used to couple two plastic fiber cables, then coupling precision is improved, but ease of operation deteriorates
Solution Approach 1:
The coupling pieces are pre-formed with precise guiding faces and fiber channels that automatically align the fiber cables during insertion. This preliminary preparation of alignment features eliminates the need for complex splicing operations on site, improving ease of operation while maintaining coupling precision through the pre-engineered geometric features.
Solution Approach 2:
The guiding faces and detent bodies on the coupling pieces enable self-alignment and self-positioning of the fiber cables during assembly. The structure automatically guides the cables into the correct position without requiring external alignment tools or complex operational procedures, thereby improving ease of operation while ensuring precise coupling.
3Length of moving object
If conventional coupling methods are used, then cable installation length is limited, but coupling cost increases
Solution Approach 1:
The male coupling piece is inserted into the female coupling piece, creating a nested structure that securely joins two fiber cables. This nested design allows for extended cable installation lengths by enabling multiple cable segments to be coupled together through simple insertion, avoiding the need for expensive splicing equipment while achieving the required total length.
Solution Approach 2:
The coupling pieces are designed as simple, inexpensive mechanical components that can be easily manufactured and replaced if needed. This approach uses low-cost coupling devices instead of expensive splicers, making the coupling process economically viable for extending cable installation lengths without significant investment in specialized equipment.

AI summary
A plastic fiber cable coupling structure includes two symmetric coupling pieces coupling with each other. The coupling piece includes a male and a female kit, the male kit has a fixing block and a flange disposed at each side thereof, and two cone-shaped fiber channels disposed therein. Besides, the female kit has a connecting hole disposed at each side thereof, a fastening block disposed at each inner side thereof, and two fiber channels disposed therein, wherein a plurality of detent bodies extend outwardly from the inner side of a first fiber channel, a coupling hole is dug out on the outer side of the first fiber channel, a guiding face is formed on the inner side of a second fiber channel with a plurality of detent bodies extending outwardly, and a coupling end extends outwardly from the outer side of the second fiber channel with a guiding face formed inside the coupling end. Therefore, the coupling piece is constituted by inserting one end of the male kit into the female kit; finally, the plastic fiber cable coupling structure is formed by connecting the two symmetric coupling pieces and using a locking piece to combine the two coupling pieces into one unit.
