Solution Overview

Problem

Existing handheld steam generators face issues with perfume oils accumulating in refill tank units due to differing evaporation behaviors, making it difficult to easily add fragrance to the steam treatment process.

Innovation Solution

Incorporation of an electrically operable piezoelectric atomizer and a detachable reservoir for a second fluid, allowing spatial separation and controlled atomization of the fragrance with the steam output, facilitated by separate energy sources for the evaporator and atomizer units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If perfume oils are added to refill tank units for steam treatment, then fragrance function is improved, but accumulation of perfume oils occurs due to different evaporation behaviors

Engineering Contradiction:
Improvefragrance functionVSAvoidaccumulation risk
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The device is divided into two separate fluid systems: a first fluid (water) in the device housing for steam generation, and a second fluid (perfume oil) in the separate reservoir unit for fragrance provision. This segmentation prevents mixing and accumulation issues while maintaining both functions independently and reliably.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a separate reservoir unit with atomizing device is added to the adapter, then ease of adding fragrance is improved, but device complexity increases

Engineering Contradiction:
Improveease of adding fragranceVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The adapter body serves multiple functions: it connects the reservoir unit to the device housing, provides structural support, and guides the mixing of steam and atomized fragrance. The reservoir unit itself functions as both storage and atomization device. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

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

3Extent of automation

If piezoelectric atomizer is used for automatic atomization of second fluid, then atomization control is improved, but energy consumption increases

Engineering Contradiction:
Improveautomatic atomizationVSAvoidenergy consumption
Core Design Contradiction:
Extent of automationVSUse of energy by moving object

Solution Approach 1:

The piezoelectric atomizer operates periodically rather than continuously, activating only when fragrance atomization is needed. This periodic operation mode reduces overall energy consumption compared to continuous operation, while still providing effective automatic atomization control when required.

Inventive Principle:
Principle #19Periodic action
