Solution Overview

Problem

Conventional steam appliances are limited in their ability to effectively clean and sanitize surfaces other than floors, lacking the flexibility and versatility needed for uneven, corner, and tight spaces.

Innovation Solution

A flexible steam frame system with a base, support elements, and a steam-permeable material, such as a towel or pocket, that allows steam to be introduced and distributed from multiple surfaces, enabling efficient cleaning of various surfaces including walls, ceilings, and tight spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional steam appliances use a fixed mop head or nozzle design, then the structure is simple and easy to manufacture, but the device cannot effectively clean corners, tight spaces, and uneven surfaces

Engineering Contradiction:
Improveability to clean various surfaces including corners and tight spacesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the steam applicator frame flexible rather than rigid. The frame can bend and flex to adapt to different surface geometries including corners, edges, and uneven surfaces. This allows the same simple structure to serve multiple cleaning functions without requiring complex interchangeable attachments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs flexible elements within the frame structure that allow the steam applicator to conform to various surface shapes. These flexible components enable the frame to bend and flex while maintaining structural integrity, providing adaptability to clean diverse surfaces without increasing overall device complexity.

Inventive Principle:
Principle #30Flexible shells and thin films

2Length of moving object

If steam is introduced into a rigid chamber, then steam distribution is controlled and efficient, but the applicator cannot reach tight spaces and corners

Engineering Contradiction:
Improvereach and flexibilityVSAvoidsteam distribution effectiveness
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The chamber structure incorporates flexible elements that allow it to expand, contract, and bend while maintaining its ability to contain and distribute steam effectively. This dynamic structure can reach into tight spaces and corners while preserving reliable steam distribution through the steam-permeable material.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses flexible framing elements that allow the chamber to conform to various geometries including tight spaces and corners. The flexible structure maintains steam containment and distribution reliability by preserving the chamber's integrity while adapting its shape to reach difficult-to-access areas.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If the steam applicator uses a rigid frame structure, then manufacturing precision is easy to achieve, but the applicator catches on edges and cannot maneuver around obstacles

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidframe structure precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The frame structure transitions from rigid to flexible, allowing the applicator to bend and flex around obstacles and edges without catching. This dynamic flexibility improves maneuverability while the flexible elements are designed with sufficient structural integrity to maintain adequate manufacturing precision for effective steam application.

Inventive Principle:
Principle #15Dynamics
