Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional yoga socks lack effective grip and shock absorption, suffer from slipping issues, and have durability and ventilation problems due to nonslip members attached via sticker or silk printing, which are not securely fixed and can detach during washing, and are limited in design and thickness adjustment.

Innovation Solution

A yoga cushion-padded sock with a cushion pad attached via mold pressing to both sides or one side, incorporating air holes for ventilation, providing enhanced grip, shock absorption, and nonslip qualities, and allowing for adjustable thickness and design variability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a nonslip member is attached using conventional methods (sticker, silk printing, silicone coating), then the attachment process is simple, but the nonslip member is easily detached during washing and durability is poor

Engineering Contradiction:

Improveattachment process simplicityVSAvoidnonslip member attachment durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The cushion pad and nonslip member are integrated into a single pre-formed unit during the knitting process, eliminating the need for separate attachment steps. This preliminary integration ensures the nonslip member cannot detach during washing while maintaining manufacturing efficiency through automated knitting processes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cushion pad and nonslip member are merged into a single integrated component that is knitted together with the sock body. This combination eliminates the separation between cushioning and nonslip functions, ensuring both durability and functional effectiveness without requiring separate attachment processes.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If a uniform thickness nonslip member is used, then manufacturing is simplified, but adequate thickness adjustment for different positions is impossible

Engineering Contradiction:

Improvenonslip member manufacturing simplicityVSAvoidnonslip member thickness uniformity

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The cushion pad is knitted with variable thickness at different locations according to the specific functional requirements of each area. Thicker regions provide enhanced cushioning where needed, while thinner regions maintain flexibility and comfort, allowing precise local adjustment of nonslip and cushioning properties.

Inventive Principle:

Principle #3Local quality

3Reliability

If a nonslip member is attached to enhance grip with the floor, then nonslip function is improved, but slipping between the sock and foot occurs and the sock is pulled backward

Engineering Contradiction:

Improvegrip with floorVSAvoidsock stability on foot

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cushion pad is positioned and integrated into the sock structure during the knitting process, ensuring proper placement on the frictional surface before the sock is worn. This preliminary positioning prevents the cushion pad from shifting or causing the sock to pull backward during use, while still providing effective floor grip.

Inventive Principle:

Principle #10Preliminary action

4Ease of manufacture

If a non-ventilated nonslip member is used, then manufacturing is simpler, but the foot sweats and becomes wet, forming a water membrane that destroys the nonslip function

Engineering Contradiction:

Improvenonslip member structure simplicityVSAvoidnonslip function effectiveness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The cushion pad incorporates a porous structure with air holes that allow sweat vapor to escape from the foot. This porous design maintains the nonslip function by preventing water membrane formation, while the integrated knitting process ensures the porous structure is seamlessly incorporated into the sock fabric.

Inventive Principle:

Principle #31Porous materials

5Ease of manufacture

If needlework is used to attach a cushion pad, then the cushion pad can be attached, but durability is low and it is uncomfortable to wear

Engineering Contradiction:

Improvecushion pad attachment capabilityVSAvoidcushion pad attachment durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The mechanical needlework attachment process is replaced with an integrated knitting process that forms the cushion pad as part of the sock fabric itself. This substitution eliminates the weaknesses of needlework attachment, providing superior durability and comfort while maintaining the cushioning function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention relates to a yoga cushion-padded sock in which a cushion pad is attached through mold pressing instead of needlework so as to adjust a thickness of the cushion pad and to simultaneously attach the cushion pad to both sides or one side. Particularly, as a yoga-exclusive sock, the cushion pad is attached to a part of a frictional surface during yoga moves so as to strengthen grip with a floor and complexly provide a shock absorption function and a nonslip quality, and the cushion pad includes air holes to be smoothly ventilated.
