Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual fiber optic rods are manually arranged in parallel to achieve high packing density, then image transmission quality is improved, but device complexity and production cost increase significantly
Solution Approach 1:
The invention employs vibration during the bundling process to enable self-organization of fiber optic rods. The rods automatically arrange themselves in a hexagonal close-packed structure through self-service mechanisms, eliminating the need for complex manual positioning systems while achieving packing densities above 90%.
Solution Approach 2:
Vibration is applied to the fiber optic rods during bundling to facilitate their self-organization into optimal arrangements. The mechanical vibration helps the rods overcome friction and settle into hexagonal close-packed configurations, achieving high packing density without complex positioning mechanisms.
2Device complexity
If fiber optic rods are bundled with random arrangement, then production complexity is reduced, but image transmission quality deteriorates due to cavities and non-parallel alignment
Solution Approach 1:
Vibration is applied during the bundling process to transform random arrangements into ordered hexagonal close-packed structures. This simple mechanical intervention enables self-organization of the fiber rods, achieving high packing density and parallel alignment without complex positioning systems.
Solution Approach 2:
The fiber optic rods self-organize into optimal hexagonal arrangements through vibration-induced self-service mechanisms. The rods automatically position themselves to minimize gaps and achieve parallel alignment, eliminating the need for complex external positioning devices.
3Measurement precision
If fiber optic rods are arranged in parallel with high packing density, then image resolution is improved, but production cost increases due to complex positioning requirements
Solution Approach 1:
The vibration-assisted bundling process enables self-service self-organization of fiber rods into hexagonal close-packed structures. This eliminates the need for expensive automated positioning systems while achieving the high packing density required for high-resolution image transmission.
Solution Approach 2:
Mechanical vibration provides a low-cost mechanism to achieve high packing density and parallel alignment. The vibration facilitates self-organization of rods into optimal arrangements, replacing expensive positioning equipment with a simple vibrational input.

AI summary
The invention relates to a fiber-optic device for transmitting electromagnetic waves in the range from 200 nm to 2 ?m, to a method for producing same and to the use of such optical devices for example in dental endoscopes. In the method, light-conducting rods are combined to form bundles in accordance with predefined rules, which relate to the cross-sectional area thereof and to the number thereof in relation to a surrounding sheath, and are fed to a drawing process. The solid fiber rod produced by means of the drawing process has an approximately hexagonal shape of the external contour, wherein, by means of the drawing process the light-conducting rods likewise have an approximately hexagonal external contour. In this way, a high packing density in the region of 99% is established in the fiber rod. By means of a further process sequence of bundling and drawing said fiber rods, high-resolution multi-fiber rods having several thousand light-conducting rods can be produced, wherein the diameter of a light-conducting rod that is contained is less than 100 ?m.
