Core-Winding Yarn Sock for Athletic Grip and Thrust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sports socks do not effectively convert the physical ability of the wearer into instantaneous force and thrust, essential for athletic performance, due to their design and material properties.
Innovation Solution
A sock with a knitted fabric configuration using a core yarn and a winding yarn wrapped around it, specifically in regions covering the sole and instep, providing enhanced friction and breathability, allowing for efficient conversion of physical ability into athletic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sports socks use traditional knitted fabric with face yarn and back yarn, then the sock provides adequate coverage and comfort, but the sock creates slippage and reduces the wearer's ability to push off the ground effectively
Solution Approach 1:
The patent applies composite materials by using a core yarn (elastomeric fiber) surrounded by a winding yarn (non-elastomeric fiber) to create a composite structure that combines elasticity with high friction. This composite yarn structure enables the sock to provide both grip and thrust while eliminating slippage, directly resolving the technical contradiction between reliability and harmful factors.
Solution Approach 2:
The patent changes the friction parameter of the knitted fabric by using a specific yarn structure (core yarn with winding yarn) that inherently provides high friction. This parameter change in the material structure allows the sock to maintain reliable grip and thrust without slippage, resolving the contradiction between reliability and harmful factors.
2Strength
If conventional sports socks use thick knitted fabric for durability and coverage, then the sock provides protection and comfort, but the sock increases weight and reduces athletic performance
Solution Approach 1:
The patent uses composite materials with a core yarn providing structural strength and a winding yarn providing durability. This composite structure achieves both strength and light weight, as the efficient material composition reduces overall weight while maintaining protective coverage, resolving the contradiction between strength and weight.
3Ease of manufacture
If conventional sports socks use traditional yarn structure, then the sock is easy to manufacture, but the sock lacks breathability and friction properties needed for athletic performance
Solution Approach 1:
The patent applies composite materials where the core yarn and winding yarn are twisted together in a specific configuration that maintains breathability while providing high friction. This composite structure achieves both manufacturing feasibility and enhanced performance properties, resolving the contradiction between ease of manufacture and reliability.
Solution Approach 2:
The patent changes the structural parameters of the yarn by creating a core-winding configuration that optimizes both breathability and friction. This parameter change in the yarn structure allows the material to maintain ease of manufacture while achieving the necessary performance characteristics for athletic socks.

AI summary
A sock includes a knitted fabric covering at least from a toe portion to a heel portion of a wearer. The knitted fabric, which is arranged in a first region covering at least sections, in a sole, corresponding to phalanges and metatarsal heads of the wearer, is formed by stitches that are knitted only by means of a covering yarn, which is a winding yarn wrapped around a core yarn.
