Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synthetic yarn splicers face issues with maintaining tensile elongation of entangled portions when used in yarn winding machines, leading to decreased production efficiency due to improper entanglement under tension.
Innovation Solution
A synthetic yarn splicer with a yarn splicing portion featuring a circular passage, a slit, and an injection hole, where a pair of clamping mechanisms positions the yarns to ensure the fluid injected effectively entangles them, reducing tensile elongation loss by directing the fluid flow along the inner surface away from the slit and injection hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the line connecting clamping positions is located at the side of the slit with respect to the first line, then the fluid can flow to the outside through the slit, but the fluid does not effectively act on the yarns and they are not appropriately swayed in the passage
Solution Approach 1:
The patent applies local quality by defining a specific predetermined area within the passage where the line connecting clamping positions must be located. This area is positioned at the side opposite to the injection hole with respect to the second line, ensuring that the fluid injected from the injection hole effectively acts on the yarns in a localized region, swaying them appropriately to form a reliable entangled portion while maintaining efficient fluid flow.
2Quantity of substance
If the line connecting clamping positions is located at the side of the injection hole with respect to the second line, then the fluid is directly sprayed to the yarns, but the fluid does not effectively act on the yarns and they are not effectively swayed in the passage
Solution Approach 1:
The patent defines a predetermined area within the passage where the line connecting clamping positions must be located. This area is positioned at the side opposite to the injection hole with respect to the second line, ensuring that even when fluid is directly injected, it effectively acts on the yarns by swaying them appropriately within the passage, forming a reliable entangled portion.
3Productivity
If conventional splicing methods are used, then the splicing operation can be performed, but the entangled portion is pulled while tension is applied and tensile elongation decreases
Solution Approach 1:
The patent replaces conventional mechanical splicing methods with a fluid-based splicing mechanism. Fluid is injected from the injection hole to act on the yarns within the passage, swaying them to form an entangled portion. This fluid-based approach creates a more reliable entanglement that can withstand winding tension without significant tensile elongation loss, while maintaining continuous splicing operation.
4Productivity
If the yarns are not appropriately entangled, then the splicing speed can be increased, but the entangled portion cannot withstand the winding tension
Solution Approach 1:
The patent optimizes the positional parameters of the clamping mechanisms by defining a predetermined area within the passage. The line connecting clamping positions must be located in this specific area, which is positioned at the side opposite to the injection hole with respect to the second line. This parameter optimization ensures that the fluid effectively acts on the yarns, creating a stable entangled portion that can withstand winding tension while maintaining efficient splicing speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration effectively forms a stable entangled portion that withstands winding tension, suppressing the decrease in tensile elongation and maintaining production efficiency.
Implementation Method 1
a fluid which is injected from the injection hole collides with the inner peripheral surface of the passage at a position facing the injection hole and flows to the slit and to the side opposite to the slit along the inner peripheral surface
Implementation Method 2
a pair of clamping mechanisms that is provided at a position interposing the passage of the yarn splicing portion in the penetration direction of the passage and clamps each of the one yarn and the other yarn inserted through the space
