Multiple Yarn Guide With Segmented Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn guide systems are complex to assemble and prone to damage, with a high number of components and a comb-shaped design that is easily damaged.
Innovation Solution
A multiple yarn guide system with a reduced number of components, featuring guide members arranged in a line that form yarn accommodating spaces, eliminating the need for a round bar guide and incorporating inclined mating surfaces and projecting portions to prevent yarn slippage and damage, allowing for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a round bar-shaped bar guide is used to provide the yarn path, then the yarn guidance function is achieved, but the number of components increases and assembly becomes difficult
Solution Approach 1:
The patent merges the functions of multiple separate guides into a single integrated guide member. The guide member includes multiple guide portions (first guide portion, second guide portion, third guide portion) that collectively perform the yarn path regulation function previously requiring separate round bar guides and regulating guides, thereby reducing component count and simplifying assembly
2Reliability
If a comb-shaped yarn guide beam is used, then yarn guidance is provided, but the structure is readily damaged
Solution Approach 1:
The patent segments the guide function into multiple independent guide portions (first guide portion, second guide portion, third guide portion) formed on a single guide member. This segmentation allows each portion to independently perform its guidance function without the structural vulnerability of comb-shaped designs, where one damaged tooth would compromise the entire structure. If one guide portion is damaged, others continue to function.
3Ease of repair
If multiple separate guides are used to regulate yarn path, then yarn guidance is achieved, but maintenance costs increase when components are damaged
Solution Approach 1:
The patent combines multiple guide portions into a single integrated guide member, so that when damage occurs, only one component (the entire guide member) needs to be replaced rather than multiple separate guides. This merging reduces the number of replaceable components and simplifies maintenance procedures, thereby reducing maintenance costs

AI summary
An object of the present invention is to provide a multiple yarn guide which is easy to assemble owing to a reduced number of components required and which is unlikely to be damaged. A multiple yarn guide 9 includes a plurality of guide pieces 15 arranged in a line. A pair of adjacent guide pieces 15 forms a yarn accommodating space S in which a traveling filament yarn Y is accommodated.
