Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical fiber core cables are coupled at given intervals to form subunits, then the optical fiber ribbon becomes more flexible and easier to deform, but it becomes difficult to distinguish between subunits
Solution Approach 1:
The patent applies different colors to the coupling resin at different positions or to different subunits. This color differentiation allows operators to easily distinguish between adjacent subunits while maintaining the flexibility benefits of the coupled structure. The colored resin does not interfere with the mechanical deformation capability.
2Ease of manufacture
If the number of cores in optical fiber core cables is increased to reduce the number of ribbon sheets, then manufacturing cost is reduced, but the complexity of handling and distinguishing individual cores increases
Solution Approach 1:
The patent divides the high-core-count ribbon into multiple subunits with fewer cores each, coupled at intervals. This segmentation allows the ribbon to be handled in smaller, more manageable sections while still achieving the cost benefits of high-core-count cables. The subunit structure simplifies installation and maintenance operations.
Solution Approach 2:
Different colors are applied to different subunits or core groups within subunits, providing visual differentiation that simplifies handling and identification. This color-coding system reduces the complexity of managing high-core-count ribbons during installation and maintenance.
3Volume of moving object
If optical fiber ribbons are made thinner and more densified to efficiently use conduits, then space utilization is improved, but the ribbons become more rigid and difficult to handle
Solution Approach 1:
By coupling core cables at intervals rather than continuously along the entire length, the patent creates a segmented structure with flexible uncoupled sections. This allows thin, dense ribbons to maintain bendability and ease of handling in the uncoupled regions while achieving space efficiency through high core density.
