Solution Overview

Problem

Conventional heat-retaining clothing with padding faces issues of bulkiness, high weight, slow drying, and maintenance challenges, particularly with cotton and feather fillings, which lead to problems like padding migration and high costs.

Innovation Solution

A laminate structure comprising a first outer layer, a second outer layer, and an inner layer with a thickness greater than the inner layer cloth, forming a space part between the outer layers, using synthetic fibers like polyester or nylon, and applying three-dimensional crinkles or shapes to enhance lightness, compactness, and quick-drying properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If cotton padding is used for heat retention, then heat retention is improved, but weight increases and the clothing becomes bulky

Engineering Contradiction:

Improveheat retentionVSAvoidweight

Core Design Contradiction:

TemperatureVSWeight of moving object

Solution Approach 1:

The patent changes the physical state and arrangement of synthetic fibers in the inner layer, creating a three-dimensional structure with air pockets that traps heat more effectively than traditional cotton padding. This structural parameter change allows achieving comparable or superior heat retention with significantly reduced weight and bulk

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses a composite structure combining outer layers with an inner layer of synthetic fibers (polyester, nylon, or acrylic) arranged in a specific three-dimensional configuration. This composite approach replaces traditional cotton or feather padding while achieving better thermal insulation performance per unit weight

Inventive Principle:

Principle #40Composite materials

2Temperature

If cotton padding is used for heat retention, then heat retention is improved, but the clothing becomes bulky and compactness in folded state deteriorates

Engineering Contradiction:

Improveheat retentionVSAvoidbulkiness

Core Design Contradiction:

TemperatureVSVolume of moving object

Solution Approach 1:

The patent transforms the inner layer into a three-dimensional structure with controlled air pockets and fiber arrangement that provides thermal insulation without requiring large volume. The crinkled or gathered fabric structure creates air traps for heat retention while maintaining a compact overall form factor

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The inner layer is constructed as a flexible, thin-walled structure that can be compressed and folded easily. The synthetic fiber composition and three-dimensional arrangement allow the layer to maintain its insulating properties while being highly compressible for compact storage

Inventive Principle:

Principle #30Flexible shells and thin films

3Temperature

If cotton padding is used for heat retention, then heat retention is improved, but drying time increases

Engineering Contradiction:

Improveheat retentionVSAvoiddrying time

Core Design Contradiction:

TemperatureVSLoss of time

Solution Approach 1:

The patent changes the material composition from cotton to synthetic fibers (polyester, nylon, acrylic) that have inherently lower moisture absorption properties. This material parameter change reduces the amount of water retained in the padding, enabling faster drying times while maintaining heat retention capabilities

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The three-dimensional structure of the inner layer creates a porous network that facilitates rapid moisture evaporation and air circulation. The air pockets and fiber arrangement promote quick drying by allowing moisture to escape efficiently while still trapping heat

Inventive Principle:

Principle #31Porous materials

4Temperature

If padding is used for heat retention, then heat retention is improved, but padding migration and leaning occur

Engineering Contradiction:

Improveheat retentionVSAvoidpadding stability

Core Design Contradiction:

TemperatureVSStability of the object's composition

Solution Approach 1:

The inner layer is constructed as an integrated flexible fabric structure rather than loose filling material. This continuous film-like structure with three-dimensional arrangement prevents migration and leaning by distributing the insulating function across the entire layer, eliminating the need for quilting or stitching to hold padding in place

Inventive Principle:

Principle #30Flexible shells and thin films
