Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for attaching nonslip members to socks are inadequate, as they fail to firmly attach to both sides, especially the inner side, and do not provide adequate ventilation, leading to separation during washing and reduced effectiveness due to moisture accumulation, with limited adjustability in thickness and size.

Innovation Solution

A method using a mold to attach silicone nonslip members with air holes to both sides of a sock, allowing for firm attachment and adjustable thickness and size, utilizing heat-pressing to secure the nonslip members, which can be patterned and ventilated to prevent moisture buildup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a nonslip member is attached to the outer side of the sock, then grip between floor and sock is strengthened, but slipping between sock and foot cannot be resolved and the sock may be pulled backward or folded

Engineering Contradiction:

Improvegrip between floor and sockVSAvoidslipping prevention between sock and foot

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The nonslip function is segmented into two separate members: one attached to the outer side of the sock for floor grip, and another attached to the inner side for foot-sock grip. This segmentation allows each nonslip member to independently perform its specific function without interfering with the other, resolving the contradiction between floor grip and foot-sock slipping prevention.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a nonslip member is attached to the inner side of the sock, then slipping between sock and foot is prevented, but the fluffy pile structure makes attachment impossible

Engineering Contradiction:

Improveslipping prevention between sock and footVSAvoidattachment feasibility on pile structure

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of attempting to attach the nonslip member to the entire fluffy pile surface, the invention applies the nonslip member locally to specific areas of the inner sock side where slip prevention is most needed. This local quality approach allows the nonslip member to be attached to the underlying structure rather than the fluffy surface, making manufacturing feasible while maintaining the pile structure's comfort properties.

Inventive Principle:

Principle #3Local quality

3Device complexity

If a nonslip member without air holes is used, then the structure is simple, but moisture accumulates and reduces nonslip effectiveness

Engineering Contradiction:

Improvenonslip member structureVSAvoidnonslip effectiveness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The nonslip member incorporates air holes creating a porous structure that allows moisture to pass through. This prevents moisture accumulation between the sock and foot, maintaining the nonslip properties by ensuring the nonslip member remains dry and effective during exercise activities.

Inventive Principle:

Principle #31Porous materials

4Ease of manufacture

If the nonslip member thickness is not adjusted according to mold area, then manufacturing is simpler, but cushioning at high-friction areas is insufficient

Engineering Contradiction:

Improvenonslip member manufacturingVSAvoidblister prevention

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The nonslip member's thickness is varied locally according to the mold area and friction requirements. Areas with higher friction and blister risk receive thicker nonslip members for enhanced cushioning, while areas with lower requirements have thinner sections. This local quality variation optimizes both protection and manufacturing efficiency.

Inventive Principle:

Principle #3Local quality
