Solution Overview

Problem

Existing portable steaming devices fail to achieve controlled and consistent diffusion of additives with steam, leading to uneven distribution and potential excessive additive emission.

Innovation Solution

A portable steaming device with a steam distribution circuit that includes a bypass circuit for incorporating additives into the steam flow, allowing for controlled emission through adjustable steam flow rates and a reservoir for limiting additive quantity, ensuring precise diffusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a portable steaming device uses a treatment face with steam outlet orifices and a cavity receiving an absorbent material impregnated with a perfume, then the device can diffuse an additive with the steam, but the diffusion is strongly linked to the contact of the treatment face with the garment and does not allow good diffusion

Engineering Contradiction:
Improveadditive diffusion quantityVSAvoiddiffusion consistency
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The steam distribution circuit is segmented into a main circuit and a bypass circuit. The bypass circuit separately handles additive diffusion while the main circuit provides primary steam flow, allowing independent control of each function and consistent additive diffusion regardless of garment contact.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bypass circuit acts as an intermediary pathway that introduces additive into the steam flow before the steam reaches the treatment face. This intermediary mechanism ensures additive is properly mixed with steam independent of direct garment contact with the treatment face.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If a portable steam remover uses a treatment face covered with a wipe allowing the diffusion of an additive, then the additive is diffused with the flow of steam, but the diffusion gradually decreases as the steam passes through the wipe

Engineering Contradiction:
Improveadditive diffusion quantityVSAvoiddiffusion duration
Core Design Contradiction:
Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The additive diffusion function is extracted from the treatment face and relocated to the bypass circuit. This separates the steam generation function (treatment face) from the additive diffusion function (bypass circuit), allowing continuous additive supply independent of steam passage through wipes.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The additive is introduced into the steam flow in advance through the bypass circuit before the steam reaches the treatment face. This preliminary mixing ensures consistent additive diffusion throughout the steaming process rather than gradual depletion through wipe saturation.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If the device incorporates a bypass circuit to control additive diffusion, then the quantity of additive emitted with the steam is better controlled, but the device complexity increases

Engineering Contradiction:
Improveadditive emission controlVSAvoidsteam distribution circuit complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The bypass circuit is merged with the existing steam distribution circuit rather than being a completely separate system. The bypass circuit integrates into the steam flow path, allowing additive control functionality to be added while sharing common components like the steam source and treatment face.

Inventive Principle:
Principle #5Merging (Combining)
