Scrim Machine Interchangeable Helical Yarn Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machines are limited to producing either square or tri-axial pattern scrims, lacking the capability to efficiently manufacture both types simultaneously, which is necessary for various industrial applications.
Innovation Solution
A machine design featuring a rotating center shaft, interchangeable helical yarn guides, and a yarn feeding wheel assembly that allows for the production of both square and tri-axial scrims by adjusting the yarn guides and wheel configurations, enabling the creation of different yarn patterns and angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate machines are used to produce square pattern scrim and tri-axial pattern scrim, then production capability for each specific pattern is ensured, but device complexity increases and manufacturing efficiency decreases
Solution Approach 1:
The machine is designed with interchangeable helical yarn guides that can be configured in different patterns (square pattern with first and second yarn guides, or tri-axial pattern with first, second, and third yarn guides). This allows a single machine to perform multiple functions and produce different scrim patterns without requiring separate dedicated machines for each pattern type.
Solution Approach 2:
The yarn guide system is divided into interchangeable modular components (first yarn guide, second yarn guide, and optionally third yarn guide) that can be selectively assembled and disassembled. This segmentation enables flexible reconfiguration of the machine to produce different scrim patterns while maintaining a single base machine structure.
2Device complexity
If a single machine is designed to produce both square and tri-axial scrims, then device complexity is reduced, but manufacturing precision for different patterns may be compromised
Solution Approach 1:
The machine employs dynamically reconfigurable yarn guide assemblies that can be adjusted and interchanged based on the desired scrim pattern. The helical yarn guides can be rotated and positioned at different angles, and the third yarn guide can be added or removed to switch between square and tri-axial patterns, maintaining manufacturing precision through controlled reconfiguration.
Solution Approach 2:
The machine allows changing geometric parameters of the yarn guide configuration (such as the angle and position of the third yarn guide for tri-axial patterns) to achieve different scrim patterns. By adjusting these parameters while maintaining the same base machine structure, precise control over the final scrim pattern is achieved.
