Solution Overview

Problem

Existing down jackets suffer from reduced warmth due to filling material accumulation in filling cavities, leading to uneven distribution and aesthetic issues.

Innovation Solution

A spacer fabric structured garment with a design comprising an upper fixed surface, lower fixed surface, and dragging parts that include dragging units with square or diamond cross-sections, monofilament or textile dragging wires, and a method of production involving bonding layers and hot press lamination to ensure even distribution of filling material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a garment is made from a single layer of fabric, then it is simple to manufacture, but it cannot provide both structure and breathability simultaneously

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoiddual functionality (structure and breathability)
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The garment is divided into multiple fabric layers with distinct functions: a first fabric layer provides structural support while a second fabric layer provides breathability. This segmentation allows each layer to be optimized for its specific function, resolving the contradiction between manufacturing simplicity and dual functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The garment uses a composite structure combining different fabric types (e.g., non-woven fabric for structure, woven or knitted fabric for breathability). This composite approach enables the garment to simultaneously achieve structural integrity and breathability, which a single fabric layer cannot provide.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If multiple fabric layers are used to provide both structure and breathability, then dual functionality is achieved, but the garment becomes complex to manufacture

Engineering Contradiction:
Improvedual functionality (structure and breathability)VSAvoidgarment structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple fabric layers are combined into a single integrated garment structure where the layers work together as a unified system. The bonding mechanism merges the structural layer and breathable layer into one functional unit, reducing complexity compared to separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Different regions of the garment use different fabric types strategically placed where needed: structural fabric in areas requiring support and breathable fabric in areas requiring ventilation. This localized approach achieves dual functionality without requiring the entire garment to be complex.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If traditional single-layer fabric is used, then the garment is comfortable against skin, but it lacks breathability and causes overheating

Engineering Contradiction:
Improveskin comfortVSAvoidoverheating and poor breathability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The breathable fabric layer is made from porous or mesh-like materials that allow air and moisture to pass through. This porous structure provides the breathability needed to prevent overheating while maintaining skin comfort through soft, skin-friendly materials.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The composite structure combines a structural fabric layer with a breathable fabric layer, where the breathable layer specifically addresses the overheating problem while the structural layer maintains comfort. Together they eliminate the harmful effects of poor breathability without sacrificing skin comfort.

Inventive Principle:
Principle #40Composite materials
