Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry from existing washing-drying machines is often ultra-dry and hot, making it difficult to iron, and re-humidification can result in excessive wetting, complicating the ironing process.
Innovation Solution
A laundry conditioning device with a closed laundry holding space and a humidifying device using a piezoelectric aerosol generator to inject controlled, non-hot moisture, which includes a water reservoir, atomization tray, and electronic control for generating a cold aerosol flow to condition the laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a washing-drying machine uses conventional drying circuits (closed or open), then the laundry is effectively dried, but the laundry becomes ultra-dry and hot, making it difficult to iron
Solution Approach 1:
The invention changes the parameters of moisture application by using a piezoelectric aerosol generator to produce fine water droplets at controlled rates, delivering moisture in a non-hot state rather than through conventional heating methods, thus achieving suitable ironing conditions without excessive heat
Solution Approach 2:
The invention utilizes phase transition by converting liquid water into aerosol form through piezoelectric vibration, creating a fine mist that evaporates gently on the laundry surface, providing moisture without the high temperatures associated with conventional steam methods
2Quantity of substance
If re-humidification is applied to ultra-dry laundry, then ironing becomes easier, but the laundry becomes excessively wet, complicating the ironing process
Solution Approach 1:
The invention incorporates feedback control through a humidity sensor that continuously monitors the moisture content of the laundry and adjusts the aerosol generation rate accordingly, preventing over-wetting while ensuring sufficient moisture for easy ironing
Solution Approach 2:
The invention applies partial action by delivering moisture in controlled, incremental amounts through the aerosol generator rather than applying large amounts at once, achieving the optimal moisture level for ironing without excessive wetting
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 device effectively conditions the laundry for easier ironing by providing quality-controllable moisture, avoiding excessive wetting and maintaining a suitable temperature for ironing.
Implementation Method 1
a piezoelectric aerosol generator which in contact with water to be converted into moisture expands and shrinks in response to a potential difference applied to the piezoelectric crystal, thus applying a high-frequency vibration (in the ultrasounds range) to the water
Implementation Method 2
applying a high-frequency vibration (in the ultrasounds range) to the water, such as to generate an instantaneous, cold aerosol flow
