Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If cooling wind is blown into the yarn running space from one side in a predetermined direction, then the yarn running space can be cooled, but some cooling wind passes through gaps between adjacent yarn running spaces causing energy waste and reduced cooling efficiency
Solution Approach 1:
The cooling device is segmented into multiple independent cooling sections, each with its own airflow passages. Partition walls divide the cooling space into separate zones, preventing cooling wind from passing through gaps between adjacent yarn running spaces. Each section handles its own airflow independently, eliminating the energy waste caused by uncontrolled airflow between sections.
Solution Approach 2:
The harmful airflow path through gaps between yarn running spaces is extracted and eliminated by introducing partition walls. These walls remove the unwanted leakage path, forcing all cooling wind to pass through the intended yarn running spaces where it can perform its cooling function effectively.
2Productivity
If partition walls are added to guide airflow between yarn running spaces, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The partition walls are merged with the existing cooling device structure, forming an integrated design. The airflow passages and partition walls are combined into a unified structure that guides cooling wind through the yarn running spaces without requiring separate, complex airflow control systems. This merging approach improves cooling efficiency while minimizing the increase in device complexity.

Implementation Method 1
a known yarn cooler is configured to cool a yarn spun out downward from a spinneret of a spinning apparatus. Such a yarn cooler is configured to blow cooling wind into a yarn running space where the yarn runs below the spinneret, and to cool the yarn running in the yarn running space.

AI summary
An object of the present invention is to efficiently cool a yarn. A hollow main box 20a is provided below a spinning beam. In the inner space of the main box 20a, spaces where filaments spun out from spinnerets run will be used as yarn running spaces 31a, and spaces provided on both sides of the yarn running spaces 31a in a front-rear direction will be used as a central space 51 and a side space 52 (side space 53). The main box 20a is provided with: a passage portion 21b which faces the central space 51 and which allows gas to flow; and an opening 24 (opening 25) which faces the side space 52 (side space 53) and which allows gas to flow. The yarn running spaces 31a are aligned in the left-right direction. Each second partition wall 22 (third partition wall 23) is provided between two yarn running spaces 31a adjacent at least in a left-right direction so that the central space 51 and the side space 52 (side space 53) are partitioned.
