Solution Overview

Problem

Existing steam cleaners often saturate carpets and require long drying times due to the lack of effective steam distribution accessories, which limits their cleaning performance and efficiency.

Innovation Solution

A quilted fabric steam pocket with a terry outer layer and inner knit fabric lining, featuring a 45-degree diagonal quilting pattern and hook-and-loop fasteners, is designed to fit over a steam frame, allowing for improved steam distribution and unlimited steering capabilities, while maintaining steam containment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a simple cloth or towel is placed on a steam frame, then the device is simple and easy to manufacture, but steam distribution is poor and carpets become overly saturated

Engineering Contradiction:
Improvesimplicity of towel constructionVSAvoidcleaning efficiency and steam distribution
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The towel is divided into multiple functional layers including an outer terry layer for steam distribution, an inner knit fabric lining with base mesh layer, padding layer, and jersey layer. This segmentation allows each layer to perform specific functions for optimized steam distribution and carpet drying

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses composite fabric construction combining different material properties: terry cloth for steam absorption and distribution, knit fabric for flexibility and fit, and padding layers for steam retention. This composite structure improves cleaning efficiency while preventing oversaturation

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If a standard towel without closure is used, then the device is simple to operate, but steam escapes and cleaning performance is reduced

Engineering Contradiction:
Improveease of towel installationVSAvoidsteam containment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The towel includes self-contained fastening features with fastening strips and snap fasteners that automatically secure the towel to the steam frame when installed, ensuring steam containment without requiring additional components or complex installation procedures

Inventive Principle:
Principle #25Self-service

3Device complexity

If a towel with limited steering capability is used, then the structure is simple, but cleaning versatility is reduced

Engineering Contradiction:
Improvestructural complexity of towelVSAvoidcleaning coverage and steering flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The towel is designed with flexible materials and a form-fitting envelope structure that allows dynamic movement and unlimited steering capabilities, enabling the user to adapt the towel to various cleaning surfaces and angles while maintaining steam containment

Inventive Principle:
Principle #15Dynamics

AI summary

A fabric steam towel for mounting onto a steam frame of a steam appliance is provided. The pocket includes two complimentary substantially planar layers of fabric joined at their peripheral edge with an open section for mounting onto the steam frame and allowing the open edges to butt against each other. The fabrics are constructed of an outer terry layer and inner material with an upper jersey layer, padding and a lower mesh layer with a 45 degree quilting pattern to improve performance. The fabric is sealed about the frame a first length of a fastener is secured to the inside face along the open edge of one layer with a complimentary length of fastener secured to the inside face of the second layer and extending beyond the edge to allow the open edges of each layer to abut each other and for the fasteners to engage and secure the fabric pocket about the edge of the frame.
