Solution Overview

Problem

Current pillow designs are difficult to clean effectively, as they often fail to allow hot water and air to penetrate to the core, leading to incomplete killing of bacteria and molds, and are either not washable or require complex processes, compromising comfort and cleanliness.

Innovation Solution

A pillow design featuring a removable inner shell case with open mesh material and a polyurethane foam backing layer, allowing for easy washing and drying, with an outer shell case that enhances water and air penetration through perforations and a mesh internal layer, ensuring thorough cleaning and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pillows use higher density materials (e.g., 300, 200 or 100 count cotton, synthetic, blended, or other tightly woven materials) for pillow cases, then comfort and quality are improved, but water and air penetration to the center of the pillow is hampered

Engineering Contradiction:
Improvecomfort and qualityVSAvoidwater and air penetration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The pillow is divided into an outer shell case and an inner shell case that can be separated. The inner shell case containing the fill material can be removed and washed independently, allowing the outer shell to maintain high-density comfortable material while the inner components enable effective cleaning through water and air penetration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner shell case is made from breathable, porous material that allows water and air to penetrate through to the center of the pillow during washing and drying. This porous structure enables effective cleaning while the outer shell maintains comfort with higher density materials.

Inventive Principle:
Principle #31Porous materials

2Ease of operation

If pillows are designed to be washable in conventional washing machines, then ease of cleaning is improved, but effective killing of bacteria and molds is compromised due to inability of hot water and air to penetrate to the core

Engineering Contradiction:
Improveease of cleaningVSAvoidkilling of bacteria and molds
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By separating the pillow into removable inner and outer shell cases, the design enables conventional washing machine compatibility while allowing water and air to reach the core fill material effectively during the wash cycle, thus killing bacteria and molds.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner shell case uses breathable porous material that facilitates penetration of hot water and air to the center of the pillow during washing, ensuring effective sterilization while maintaining ease of cleaning in conventional machines.

Inventive Principle:
Principle #31Porous materials

3Reliability

If pillows are made with regular polyester, feathers, and/or down fill, then comfort is improved, but drying difficulty increases significantly

Engineering Contradiction:
ImprovecomfortVSAvoiddrying time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The inner shell case is constructed from breathable porous material that allows rapid air circulation and water evaporation during drying. This enables pillows with comfortable fill materials like polyester, feathers, and down to dry quickly without compromising comfort.

Inventive Principle:
Principle #31Porous materials

4Ease of operation

If chemicals and various materials are used to solve washing problems, then cleaning capability is improved, but comfort is compromised as chemicals settle and make the pillow uncomfortable

Engineering Contradiction:
Improvecleaning capabilityVSAvoidcomfort
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The separation of inner and outer shell cases allows effective cleaning through physical water and air penetration without relying on chemicals. The removable inner shell can be thoroughly washed and dried, eliminating the need for chemical treatments that would compromise comfort.

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments are directed towards a pillow with a removable core that includes a plurality of cut foam pieces of various or similar shapes/sizes. The pillow may include an outer shell case and an inner shell case (i.e., the removable core). The outer shell case may be made of a plurality of layers, including a backing layer positioned between an external layer and an internal layer. The backing layer may comprise a foam material. And the internal layer and the inner shell case may comprise an open mesh material. The inner shell case may be removably inserted into the outer shell case. A plurality of foam pieces may be disposed inside the inner shell case.
