Solution Overview

Problem

Existing steam cleaning apparatuses, such as steam mops, are limited in their versatility and adaptability for cleaning different surface types and hard-to-reach areas, as they are typically designed for specific modes of operation.

Innovation Solution

A convertible steam cleaning apparatus that can be transformed between multiple modes of operation, including upright mopping, handheld, remote cleaning, and handheld accessory modes, allowing for efficient cleaning of various surfaces and hard-to-reach areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a steam cleaning apparatus is designed for a specific mode of operation (e.g., upright mopping), then it can effectively clean that specific surface type, but it lacks versatility for cleaning different surface types and hard-to-reach areas

Engineering Contradiction:
ImproveversatilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The steam cleaning apparatus is divided into separable components including a handle assembly, steam generator, and interchangeable cleaning heads. This segmentation allows users to detach and replace different cleaning heads (mopping head, brush attachment, extension wand) based on the specific cleaning task, thereby achieving versatility without requiring a completely different device for each surface type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The apparatus incorporates a universal interface system that allows a single steam generator to work with multiple types of cleaning heads and attachments. The standardized connection mechanism enables one base unit to perform multiple cleaning functions across different surface types (floors, tiles, countertops, hard-to-reach areas) by simply changing the attachment, thus achieving multi-functionality without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the steam delivery system uses a simple direct connection, then the structure is simple, but it does not allow for interchangeable attachments and different cleaning modes

Engineering Contradiction:
ImproveadaptabilityVSAvoidmanufacturability
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The steam delivery system incorporates a dynamic connection interface that transitions from a fixed direct connection to a modular interchangeable system. The connection mechanism includes detachable couplings and standardized mounting interfaces that allow the steam delivery path to be reconfigured based on the attached cleaning head, providing adaptability while maintaining relatively simple manufacturing through standardized components.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The convertible design enables efficient cleaning of diverse surfaces and hard-to-reach areas, enhancing versatility and adaptability while maintaining effective steam delivery.

Implementation Method 1

The pump or valve outlet is fluidly connected to a steam boiler with a heating element to heat the water. The steam boiler generates steam

Methodology Applied
Scientific EffectHeating: Heating

Implementation Method 2

The steam boiler generates steam, which is directed towards the surface to be cleaned through a nozzle or manifold mounted in a foot assembly that engages the floor surface

Methodology Applied
Scientific EffectSteam delivery:

Implementation Method 3

Steam vapor eventually saturates the entire cleaning pad as the moisture wicks outwardly from the point of steam application

Methodology Applied
Scientific EffectCapillary action: Capillary Action

AI summary

A steam cleaning apparatus (10) for delivering steam of a surface to be cleaned is provided with a steam unit (12), a handle tube (14), and an indexable base (16). The base (16) can be indexed between a wide orientation where a long edge (82) of the base (16) is orthogonal to the direction of travel and a narrow orientation where a short edge (84) of the base (16) is orthogonal to the direction of travel.
