Problem

Traditional warm-keeping cotton clothes and down jackets suffer from poor moisture transfer, static electricity issues, complex processing, and air impermeability, leading to temperature loss, electrostatic damage, and difficulties in machine washing.

Innovation Solution

A dynamically warm-keeping garment with a one-way moisture transferring fabric featuring a three- or five-layer structure, including a surface layer, warm-keeping layer, and lining layer, utilizing one-way moisture transferring woven fabrics with hydrophobic agents and metal conductive yarns for anti-static properties, allowing real-time moisture and heat management without additional ventilation windows.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional warm-keeping cotton clothes and down jackets are used, then warmth is provided, but moisture transfer is poor causing sweat to stick to skin and temperature loss occurs

Engineering Contradiction:
Improveheat lossVSAvoidmoisture transfer function
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The garment is divided into multiple functional layers: an inner layer with hydrophilic properties for moisture absorption, a middle layer with hydrophobic properties for moisture blocking and warmth, and an outer layer for protection. This segmentation allows each layer to perform its specific function optimally, resolving the contradiction between warmth and moisture transfer by creating a controlled moisture management system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the fabric are given different properties: the inner layer is treated with hydrophilic agents to absorb moisture, while the middle layer is treated with hydrophobic agents to block moisture and retain heat. This local differentiation of material properties enables simultaneous moisture transfer and heat retention functions.

Inventive Principle:
Principle #3Local quality

2Temperature

If traditional fabrics are used to provide warmth, then thermal insulation is achieved, but static electricity accumulates causing electrostatic damage

Engineering Contradiction:
Improvethermal insulationVSAvoidstatic electricity
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The garment combines multiple materials with complementary properties: natural fibers (cotton, wool) for thermal insulation, synthetic fibers (polyester, polypropylene) for moisture management, and conductive fibers for static electricity dissipation. This composite structure resolves the contradiction by integrating materials that simultaneously provide warmth and prevent static accumulation.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

Conductive fibers are introduced as an intermediary element within the fabric structure to provide a pathway for static electricity dissipation. These conductive elements act as mediators between the insulating fabric layers and the environment, allowing controlled electrical discharge while maintaining thermal insulation properties.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If additional ventilation windows with zippers are added to achieve heat dissipation and moisture removal, then moisture transfer is improved, but device complexity and processing difficulty increase

Engineering Contradiction:
Improvemoisture transfer functionVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fabric structure itself provides moisture transfer and ventilation functions through its multi-layer construction with hydrophilic and hydrophobic properties. The garment automatically regulates moisture and heat through the inherent properties of the fabric layers, eliminating the need for additional mechanical ventilation components like zippers and windows, thus reducing complexity while maintaining functionality.

Inventive Principle:
Principle #25Self-service

4Temperature

If traditional warm-keeping garments are made air-tight for warmth, then thermal insulation is improved, but machine washing becomes difficult due to air pressure issues

Engineering Contradiction:
Improvethermal insulationVSAvoidmachine washability
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The fabric structure incorporates controlled porosity and breathable channels that allow air circulation while maintaining thermal insulation. The multi-layer construction with hydrophobic barriers creates pathways for air and moisture vapor transmission, preventing air pressure buildup during machine washing while preserving warmth through trapped air pockets and insulating layers.

Inventive Principle:
Principle #31Porous materials

The garment achieves real-time dynamic moisture transfer and warm-keeping, reducing heat loss, preventing static electricity damage, simplifying processing, and enabling machine washability while maintaining warmth and dryness in cold environments.

Implementation Method 1

The mechanism of one-way moisture transfer of a fabric is the capillary effect due to a pressure difference. Under the action of the capillary effect and the pressure difference, liquid moisture in the fabric diffuses automatically from an inner layer to an outer layer.

Scientific EffectHydrophobic effect: Hydrophobe

Implementation Method 3

the lining layer is the same as the surface layer; furthermore, metal conductive yarns are spaced at an interval of 2-5 cm in a weft direction of the lining layer to weaken high voltage electrostatic mass caused by friction between the chemical fiber material and the human body.
