Solution Overview

Problem

The existing Stelmor air-cooling process results in non-uniform cooling of spinning coils due to uneven stacking thickness and significant temperature fluctuations at overlapping points, affecting the quality of finished wire products.

Innovation Solution

A cooling roller way with staggered guiding mechanisms installed on both sides of the roller way body, which changes the running trajectory of the coil to uniformly distribute overlapping points, thereby reducing cooling non-uniformity and improving the organizational structure of the wire.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If coils are distributed in a continuous circle on the air-cooling roller way body, then the cooling process is simple and continuous, but the stacking thickness of overlapping points becomes non-uniform (large at both sides and small in the middle), causing non-uniform heating and degraded wire product performance

Engineering Contradiction:
Improvecontinuous cooling processVSAvoidcooling uniformity
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies asymmetry by staggering the guiding mechanisms at both sides of the roller way body, creating an asymmetric trajectory pattern that transforms the symmetric continuous circular distribution into a staggered overlapping pattern. This asymmetric arrangement ensures that overlapping points are uniformly distributed along the roller way body, eliminating the non-uniform stacking thickness (large at sides, small in middle) and achieving uniform cooling throughout the coil.

Inventive Principle:
Principle #4Asymmetry

2Manufacturing precision

If guiding mechanisms are installed to change the running trajectory of the coil, then the overlapping points can be uniformly distributed, but the device complexity increases

Engineering Contradiction:
Improveoverlapping point distribution uniformityVSAvoidguiding mechanism structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the guiding mechanism into multiple independent components: guiding wheels, fixed seats, and adjustable positioning devices. Each side of the roller way body has separate guiding mechanisms that can be independently adjusted. This segmented structure allows for precise control of the coil trajectory while maintaining ease of installation and adjustment, balancing the need for uniform overlapping point distribution with acceptable device complexity.

Inventive Principle:
Principle #1Segmentation
