Solution Overview

Problem

Chenille carpets are highly hygroscopic, prone to mildew, and difficult to clean due to their tufted piles, which trap dirt and moisture, reducing their service life.

Innovation Solution

A chenille carpet with a three-dimensional breathable base layer and weaved layer made of chenille threads over 1 cm in diameter, using plain knitting needles, combined with a nylon coil support layer and mesh layers for improved breathability and ease of cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If chenille carpets are made using tufting chenille yarn on a base fabric, then the carpets have uniform and neatly arranged piles, but the carpets become highly hygroscopic and prone to mildew

Engineering Contradiction:

Improveuniform and neatly arranged pilesVSAvoidhygroscopicity and mildew

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent uses a porous base fabric with breathable structure that allows air circulation through the carpet. The porous design prevents moisture accumulation while maintaining the neat pile appearance, thus resolving the contradiction between uniform piles and hygroscopicity.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The patent combines chenille yarn with a breathable base fabric material that has moisture-wicking properties. This composite structure maintains the aesthetic uniform piles while the base fabric material prevents mildew by managing moisture effectively.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If chenille carpets have longer suede piles, then the carpets provide better comfort, but they easily trap dirt and become difficult to clean

Engineering Contradiction:

ImprovecomfortVSAvoidease of cleaning

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent creates a three-dimensional carpet structure with raised pile height. This dimensional change allows debris to sit on top of the carpet surface rather than being trapped within the fibers, making cleaning easier while preserving comfort.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the carpet into distinct layers including a breathable base layer and a pile layer. This segmentation allows the pile to be optimized for comfort while the base layer facilitates easy cleaning by preventing dirt entrapment.

Inventive Principle:

Principle #1Segmentation

3Shape

If chenille carpets use traditional tufting construction, then the carpets have neat appearance, but the carpets have poor breathability and moisture resistance

Engineering Contradiction:

Improveneat appearanceVSAvoidbreathability and moisture resistance

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The patent employs a porous base fabric with intentional openings and breathable structure. This allows air and moisture vapor to pass through while maintaining a neat appearance from the front, resolving the contradiction between appearance and breathability.

Inventive Principle:

Principle #31Porous materials
