Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional single mode fibers are used to increase port count, then network connectivity and service capability are improved, but device size and bulkiness increase significantly
Solution Approach 1:
The patent merges multiple single mode fibers into a single multicore fiber bundle, where each core functions as an independent optical channel. This consolidation reduces the number of separate fiber components, connectors, and alignment mechanisms needed, directly decreasing device volume while maintaining high port count connectivity
Solution Approach 2:
The multicore fiber serves multiple functions simultaneously - each core acts as an independent optical waveguide for different ports/channels. This multi-functionality allows a single fiber component to replace what would traditionally require multiple separate single mode fibers, reducing overall device size while increasing adaptability
2Adaptability or versatility
If conventional single mode fibers with high port count are used, then network service capability is improved, but manufacturing cost increases
Solution Approach 1:
By combining multiple optical channels into a single multicore fiber structure, the patent reduces the total number of components that need to be manufactured, assembled, and tested. This includes fewer connectors, alignment mechanisms, and housing structures, directly lowering manufacturing complexity and cost while maintaining high service capability
3Adaptability or versatility
If conventional single mode fibers are used to increase port count, then network scalability is improved, but device complexity increases due to more moving parts
Solution Approach 1:
The patent merges multiple independent fiber handling operations into a single integrated multicore fiber assembly. This consolidation eliminates numerous individual connectors, alignment mechanisms, and mounting structures that would each add complexity and potential failure points, thereby reducing overall device complexity while enabling network scalability
4Adaptability or versatility
If conventional single mode fibers with high port count are used, then network connectivity options are improved, but reliability decreases due to more points of failure
Solution Approach 1:
By consolidating multiple optical channels into a single multicore fiber with integrated alignment and coupling mechanisms, the patent reduces the total number of interfaces, connectors, and moving parts. Each reduction in component count eliminates potential failure points, thereby improving reliability while maintaining diverse connectivity options across all ports
