Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile tools face challenges in manufacturing and handling, particularly during loop formation in textile machines, where tools are often complex to assemble and require precise alignment, leading to potential errors and increased post-processing requirements.
Innovation Solution
A textile tool part pair with two interconnected parts that can be separated manually via a predetermined breaking connection, allowing for easier manufacturing and handling, where the parts can be manufactured as a single unit and separated just before insertion into the machine, simplifying the assembly process and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If textile tool parts are manufactured as separate components requiring assembly, then manufacturing flexibility is improved, but assembly complexity and potential alignment errors increase
Solution Approach 1:
The patent combines two separate textile tool parts into a single integrated component with a predetermined breaking connection. This merging eliminates the assembly step while maintaining the benefits of having two parts (such as reduced thickness sections), thereby resolving the contradiction between manufacturing flexibility and assembly complexity.
Solution Approach 2:
The breaking connection is pre-formed during manufacturing at a specific location between the two parts. This preliminary action allows the parts to be manufactured as one unit and then easily separated when needed, eliminating the need for complex assembly operations while maintaining manufacturing flexibility.
2Manufacturing precision
If textile tool parts are manufactured as a single integrated unit, then manufacturing accuracy and alignment are improved, but flexibility in handling and assembly is reduced
Solution Approach 1:
The integrated textile tool is segmented by incorporating a predetermined breaking connection that allows easy separation into two parts. This segmentation enables the tool to be manufactured as one unit for precision alignment, then easily divided into separate parts for flexible handling and installation, resolving the contradiction between manufacturing precision and handling flexibility.
Solution Approach 2:
The breaking connection is pre-positioned during manufacturing at the optimal location for separation. This preliminary action ensures that when the tool is manufactured as an integrated unit, precise alignment is achieved, but when separation is needed, it can be done easily at the predetermined location, maintaining both precision and flexibility.
3Ease of operation
If a breaking connection is added to allow separation of parts, then handling and assembly ease is improved, but structural strength is reduced
Solution Approach 1:
The breaking connection is designed with different local properties than the rest of the textile tool structure. At the connection location, the material or geometric properties are modified to enable easy separation while maintaining full strength in the working sections of the tool, thus resolving the contradiction between separation ease and connection strength.

AI summary
A textile tool part pair (15) consisting of two textile tool parts (16) and a method of equipping a textile machine with the aid of such a textile tool part pair (15) are disclosed. Each textile tool part (16) extends in a longitudinal direction (L) between a trailing end (21) and a leading end (22). Proceeding from the trailing ends (21) thereof, the textile tool parts (16) extend away from one another and counter to one another as far as the leading end (22). At the trailing ends (21), the two textile tool parts (16) of a common textile tool part pair (15) are interconnected by a predetermined breaking connection (45). The predetermined breaking connection (45) can be manually separated without tools, in particular by bending about a bending axis (A).
