Solution Overview

Problem

Existing steam cleaning devices face challenges in decoupling the usage of sanitizing compositions from the water supply and cleaning cloth, leading to inefficient usage, incorrect dosing, and potential residue or damage issues.

Innovation Solution

A steam cleaning device with a dedicated chamber for the composition, accessible separately from the cleaning cloth, that is perfused by steam and has a steam-tight seal, allowing independent composition refilling and preserving the composition's efficacy, along with an interlock mechanism for safety and optional time-delay mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the composition is introduced into the water reservoir of the steam cleaning device, then the composition is delivered with the steam during cleaning operations, but the composition is exhausted at the same time as the reservoir is emptied of water, requiring correct dosage to avoid residue or damage

Engineering Contradiction:
Improvecomposition deliveryVSAvoidcomposition dosage control
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The invention divides the composition delivery system into separate components: a reusable dispenser unit that can be detached and replaced independently from the water reservoir. This segmentation allows the composition supply to be decoupled from water consumption, enabling users to refill or replace composition without emptying the water reservoir, thus avoiding dosage control issues while maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the composition is provided in encapsulated form associated with a fabric layer of a cleaning cloth, then the composition can be released by exposure to steam, but whenever the cloth needs cleaning or replacing, the composition has to be treated in some way by a user at the same time

Engineering Contradiction:
Improvecomposition releaseVSAvoidcomposition maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention separates the composition containment function from the cleaning cloth function by introducing a dedicated dispenser unit that can be attached to or integrated with the steam cleaning device. This dispenser unit contains the composition in a controlled manner and releases it independently of cloth replacement cycles, ensuring reliable composition delivery while simplifying user operation as composition maintenance becomes independent of cloth maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dispenser unit acts as an intermediary between the steam generation system and the composition application point. It receives steam from the device, activates the composition through steam exposure, and delivers it to the cleaning surface. This intermediary mechanism ensures controlled composition release based on steam exposure rather than manual intervention during cloth changes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a dedicated chamber for composition is provided in the steam cleaning head, then the composition usage can be decoupled from water supply and cleaning cloth replacement, but the device structure becomes more complex with additional components

Engineering Contradiction:
Improveusage independenceVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dispenser unit is designed to perform multiple functions: it stores the composition, controls its release, and can be easily attached to or integrated with the steam cleaning device. This multi-functional design justifies the additional structural elements by consolidating several functions into a single modular component, reducing the need for separate mechanisms for each function.

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

Solution Approach 2:

The dispenser unit can be designed to nest within or integrate with existing components of the steam cleaning device, such as being housed within the steam cleaning head or attached to the handle assembly. This nesting approach minimizes the overall device footprint and reduces the visual and structural complexity while maintaining the functionality of independent composition delivery.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

In a first aspect, the present invention provides a steam cleaning device, the device comprising a supply of water for generating steam, and a steam cleaning head for ejecting steam generated from said supply of water in proximity to a surface to be cleaned, wherein the steam cleaning head comprises a portion for receiving a composition adapted to be used in conjunction with such a steam cleaning device, the portion being perfused by steam during ejection by said steam cleaning head of steam generated from said supply of water. This has the advantage that the composition may be changed by a user dependent only on the user's requirements and the rate of consumption of the composition, and independently of both the rate of consumption of water by the steam cleaning device and any need to remove, clean or replace a cleaning cloth mounted on the steam cleaning head. In a second aspect, the present invention also provides an encapsulated composition adapted to be used in conjunction with a steam cleaning device comprising a supply of water for generating steam, wherein the encapsulated composition has a shape adapted to fit a portion of a steam cleaning head of the steam cleaning device, which portion is perfused by steam during ejection by said steam cleaning head of steam generated from said supply of water. Such a "must-fit" adaptation of the encapsulated composition provides the possibility that only encapsulated compositions suitable for use in a particular steam cleaning device can be charged into that device, in order to ensure correct dosage by the composition of the steam generated by the device.
