Solution Overview

Problem

Double socks with excellent heat retention properties often cause stuffiness in the foot area, especially during vigorous exercise or in warm environments.

Innovation Solution

A multi-knitted wearable garment with at least one bulky knitted fabric layer for heat retention and one water-absorbing and quick-drying knitted fabric layer, which can be positioned strategically to reduce heat loss and prevent moisture buildup, incorporating features like pseudo pile knitting for enhanced air flow and diffusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a bulky knitted fabric is used to improve heat retention properties, then heat retention is enhanced, but water-absorbing and quick-drying properties deteriorate

Engineering Contradiction:

Improveheat retention propertiesVSAvoidwater-absorbing and quick-drying properties

Core Design Contradiction:

TemperatureVSQuantity of substance

Solution Approach 1:

The wearable garment is divided into multiple fabric layers with different functional properties. The bulky knitted fabric layer provides heat retention, while a separate water-absorbing and quick-drying knitted fabric layer handles moisture management. This segmentation allows each layer to optimize its specific function without compromise.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The garment combines different types of knitted fabrics with distinct properties into a composite structure. The bulky knitted fabric (with higher heat retention) is integrated with water-absorbing and quick-drying knitted fabric, creating a multi-functional material system that simultaneously provides thermal insulation and moisture management capabilities.

Inventive Principle:

Principle #40Composite materials

2Temperature

If a bulky knitted fabric layer is added for heat retention, then thermal insulation improves, but breathability and air flow deteriorate

Engineering Contradiction:

Improveheat retention propertiesVSAvoidst stuffiness

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

Different regions of the garment have different fabric compositions tailored to local requirements. The bulky knitted fabric is strategically placed in areas requiring maximum heat retention, while water-absorbing and quick-drying fabric with better breathability is positioned in areas prone to moisture accumulation and stuffiness, optimizing both thermal insulation and air flow locally.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If multiple knitted fabric layers are combined to achieve both heat retention and water-absorbing properties, then functional performance improves, but device complexity increases

Engineering Contradiction:

Improvefunctional performanceVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple knitted fabric layers with different functions are combined into a single integrated wearable garment structure. The bulky knitted fabric layer and water-absorbing and quick-drying knitted fabric layer are joined together to form a unified product that delivers both heat retention and moisture management functions simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

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 multi-knitted garment maintains heat retention while preventing stuffiness by reducing heat loss and moisture accumulation, ensuring comfort during various activities and temperature conditions.

Implementation Method 1

the bulky knitted fabric makes it possible to reduce or inhibit the loss of heat from the area where the garment is worn to the floor or shoes, which are cooler than body temperature, through thermal conduction

Methodology Applied

Scientific EffectThermal conduction: Conduction (thermal)

Implementation Method 2

The second knitted fabric layer includes a region formed with a water-absorbing and quick-drying knitted fabric

Methodology Applied

Scientific EffectCapillary action: Capillary Action
