Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical fibers are arranged on the same plane to facilitate handling, then ease of operation is improved, but crosstalk and signal loss occur at intersection points
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional configuration where optical fibers are arranged on different planes. The first and second optical fiber arrays are positioned on different planes, and the optical waveguides connect them through spatial routing, eliminating intersection points and preventing crosstalk while maintaining handling ease.
2Productivity
If the number of optical fibers is increased to enhance signal transmission capacity, then productivity is improved, but device complexity and crosstalk increase
Solution Approach 1:
By utilizing three-dimensional space with optical fiber arrays on different planes, the patent enables increased fiber density and transmission capacity without proportionally increasing complexity. The structured arrangement of waveguides and arrays provides an organized routing system that scales efficiently.
Solution Approach 2:
The optical connection component is divided into distinct segments: first optical fiber array, second optical fiber array, and optical waveguides. This segmentation allows each component to be optimized independently and facilitates modular assembly, reducing overall system complexity while supporting high fiber counts.
3Volume of moving object
If optical fibers intersect on the same plane to achieve compact arrangement, then volume is reduced, but crosstalk and signal loss occur
Solution Approach 1:
The patent eliminates crosstalk by arranging optical fibers on different planes rather than having them intersect on the same plane. The first and second optical fiber arrays are positioned on different planes, and optical waveguides connect them through controlled spatial routing, preventing harmful intersections while maintaining compact overall dimensions.

AI summary
An optical connection component includes a first surface extending in a second direction intersecting the first direction and in a third direction intersecting both the first direction and the second direction; and a second surface extending in the second direction and the third direction and arranged with the first surface along the first direction. Each of the plurality of cores extends from the first surface along the first direction, and is bent in the third direction to extend to the second surface. The plurality of cores are arranged along the second direction on each of the first surface and the second surface. An order in which the plurality of cores are arranged on the first surface as a whole and an order in which the plurality of cores are arranged on the second surface as a whole are different from each other.
