Bendable Knitting Needle for Ergonomic Stitch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knitting needles with rigid bends are cumbersome, prone to causing minor injuries, and difficult to use for producing knitted products with smaller diameters, as they require frequent needle changes and are not ergonomic, leading to potential stitch tension and stretching issues.
Innovation Solution
A bendable knitting needle with a central elastic shaft portion allows for easier manipulation and reduced needle changes, enabling the production of round cross-sectional products with three needles, which can be aligned to maintain stitch circularity and prevent tension, and can be transported compactly when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rigid bent knitting needles are used to produce round cross-sectional products, then the number of needle changes is reduced, but the ergonomics deteriorates and the risk of injury increases due to fixed inclination angles
Solution Approach 1:
The knitting needle incorporates a bendable central portion that allows the inclination angle between the two shaft portions to be dynamically adjusted according to the user's hand position and knitting requirements, rather than being fixed at a rigid angle. This enables ergonomics optimization while maintaining reduced needle changes.
Solution Approach 2:
The inclination angle parameter of the knitting needle is made variable through the bendable central portion, allowing users to adjust the angle to suit different hand sizes and knitting positions, thereby improving ergonomics while preserving the efficiency benefit of reduced needle changes.
2Productivity
If rigid bent knitting needles are used to produce round cross-sectional products, then the number of needle changes is reduced, but the device becomes bulky and takes up more space
Solution Approach 1:
The bendable central portion allows the knitting needle to be flexible during use but can be straightened when not in use, enabling compact storage and transport while maintaining the operational benefits of the bent configuration for reduced needle changes.
Solution Approach 2:
The central portion of the knitting needle is designed as a flexible element that can bend into various configurations during knitting but can be returned to a straight, compact form for storage, reducing space occupation when not in use while preserving functional benefits during use.
3Productivity
If rigid bent knitting needles are used to produce small diameter products, then the minimum product diameter is defined by the rigid bend, but the adaptability to different product sizes deteriorates
Solution Approach 1:
The bendable central portion allows the knitting needle to be adjusted to different curvature radii, enabling the production of small diameter products by increasing the bend curvature, while maintaining adaptability to various product sizes through dynamic adjustment rather than being constrained by a fixed rigid bend radius.
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 bendable design reduces the frequency of needle exchanges, prevents stitch tension, and allows for easier production of smaller diameter knitted products, while maintaining stitch quality and reducing the risk of slipping stitches during and after knitting.
Implementation Method 1
a bendable knitting needle (1) having a shaft portion (2) and a first and second leg (3; 4)... on account of the bendable shaft portion (2), a variable angle (9) is formed between the two legs (3; 4)

AI summary
The present disclosure relates to a knitting needle for a knitting set for producing cross-sectionally round knitted products, having a first leg extending in a variable manner from a bendable shaft portion in a first extension direction to a first free end suitable for holding stitches, and a second leg extending in a variable manner from the bendable shaft portion in a second extension direction to a second free end suitable for holding stitches, wherein the free ends are in the form of rounded tips, and wherein the center of gravity of the knitting needle is arranged within the shaft portion, wherein the first extension direction and the second extension direction are at a variable angle to one another.
