Zonal Elastic Shoe Knit Structure Without Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shoe materials require additional stitching processes to achieve zonal elasticity, leading to low production efficiency and inefficiencies in manufacturing.
Innovation Solution
A zonal elastic shoe material is created with a surface layer, jacquard layer, and pattern-bar zonal-elastic layer, utilizing multifilament yarns and spandex inlays to achieve designated elasticity in specific regions, eliminating the need for stitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional textile fabrics are stitched together to achieve zonal elasticity, then the desired elastic effect is obtained, but the production process becomes complex and efficiency decreases
Solution Approach 1:
The knitting machine is divided into multiple independent knitting zones (first knitting zone, second knitting zone, third knitting zone) that can be controlled separately. Each zone can produce different knit structures (mesh, compact, chain) simultaneously, eliminating the need to stitch separate elastic and non-elastic fabric pieces together, thus achieving zonal elasticity while maintaining high production efficiency
Solution Approach 2:
The patent combines multiple knitting functions into a single integrated knitting machine. The machine integrates multiple knitting zones, different guide bar systems (first guide bar, second guide bar, third guide bar), and pattern bar mechanisms into one device that can produce the entire zonal elastic shoe upper material in a single continuous knitting process, eliminating the need for separate stitching operations

3Adaptability or versatility
If elastic and non-elastic fabric pieces are stitched together, then zonal elasticity is achieved, but production time increases
Solution Approach 1:
The knitting machine is divided into multiple independent knitting zones (first knitting zone, second knitting zone, third knitting zone) that can be controlled separately. Each zone can produce different knit structures (mesh, compact, chain) simultaneously, eliminating the need to stitch separate elastic and non-elastic fabric pieces together, thus achieving zonal elasticity while maintaining high production efficiency
Solution Approach 2:
The knitting machine prepares different knit structures (mesh structure in first knitting zone, compact knit structure in second knitting zone, chain knitting structure in third knitting zone) simultaneously during a single knitting process, rather than producing separate pieces and stitching them later. This preliminary creation of all required zones in one operation significantly reduces production time

Implementation Method 1
The elastic region is knitted with a multifilament yarn into a mesh structure... The pattern-bar zonal-elastic layer is provided on the elastic region... formed by a spandex inlay applied on the layer of the mesh structure
Implementation Method 2
The surface layer is knitted with a multifilament yarn into a chain knitting structure by a loop-forming ground bar GB1... The jacquard layer is superimposed on the surface layer, and includes an elastic region and a non-elastic region. The elastic region is knitted with a multifilament yarn into a mesh structure by a first pair of jacquard guide bars, and the non-elastic region is knitted with a multifilament yarn into a compact knit structure
