Solution Overview

Problem

Existing mattress covers with spacer fabrics face issues of limited breathability, rigidity, and reduced comfort due to brittle threads, which affect ventilation and user experience.

Innovation Solution

A mattress cover with a three-layer 3D spacer fabric featuring a honeycomb-like mesh structure on its outer surface, comprising an outer layer of textured multifilament yarn, a middle layer of monofilament yarn as a filler, and an inner smooth layer, providing enhanced air circulation, moisture removal, and elasticity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional 3D spacer fabrics are used for mattress covers, then air permeability and ventilation are improved, but the fabric becomes rigid and difficult to bend, limiting sleeping comfort

Engineering Contradiction:

Improveair permeabilityVSAvoidflexibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies porous materials by incorporating a honeycomb mesh structure with recesses open to the outside in the cover fabric. This structure provides numerous open channels that facilitate air circulation and moisture transport while maintaining fabric flexibility, resolving the contradiction between ventilation and flexibility found in conventional spacer fabrics.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The patent uses composite materials by combining the honeycomb mesh structure with a knitted fabric base material. This composite construction integrates the breathability benefits of the honeycomb structure with the flexibility and softness of knitted fabric, achieving both ventilation and comfort simultaneously.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If knitted spacer fabrics are used to increase extensibility and softness, then comfort is improved, but breathability and air exchange are insufficient

Engineering Contradiction:

ImprovesoftnessVSAvoidbreathability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates porous materials through the honeycomb mesh structure with open recesses that create extensive air channels. This porous structure is integrated into the knitted fabric to ensure that breathability is maintained while the knitted construction provides the desired softness and extensibility.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The patent applies dimensionality change by creating a three-dimensional honeycomb mesh structure with recesses that extend through the fabric thickness. This 3D architecture provides vertical air channels in addition to the horizontal knitted structure, enhancing breathability without compromising the softness provided by the knitted base.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If ventilation strips made of highly permeable material are added to conventional mattress covers, then air exchange is improved, but the device complexity and processing difficulty increase

Engineering Contradiction:

ImproveventilationVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the ventilation function directly into the cover fabric itself by integrating the honeycomb mesh structure with the knitted fabric. This unified construction eliminates the need for separate ventilation strips, reducing structural complexity while maintaining effective air exchange throughout the entire mattress cover surface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent applies universality by designing the cover fabric to perform multiple functions simultaneously: the honeycomb mesh structure provides ventilation, the knitted base provides flexibility and softness, and the integrated construction provides durability. This multi-functional fabric replaces what would otherwise require multiple separate components including ventilation strips.

Inventive Principle:

Principle #6Universality (Multi-functionality)
