Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers face challenges in effectively reaching all parts of dishes, especially when loaded densely, leading to high water and detergent consumption, and increased energy costs for heating the washing liquid.
Innovation Solution
A washing method utilizing an ultrasound nebulizing system to create a fine aerosol of detergent solution that diffuses into the washing compartment, allowing for efficient cleaning of hard-to-reach areas without simultaneous mechanical washing, and incorporating a controlled heating system to optimize detergent enzyme activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If large amounts of water and detergent are used to ensure all parts of dishes are reached, then cleaning coverage is improved, but water and detergent consumption increases
Solution Approach 1:
The patent changes the physical state and distribution parameters of the washing liquid by using an ultrasonic nebulizer to convert liquid detergent solution into fine aerosol particles. This parameter change allows the washing substance to be distributed more uniformly and penetrate into previously inaccessible areas of dishes, improving cleaning coverage without increasing overall consumption.
Solution Approach 2:
The patent replaces the conventional mechanical spray system with an ultrasonic nebulization system. Instead of using high-pressure mechanical spraying that consumes large amounts of liquid, the system uses ultrasonic vibration to generate fine aerosol particles that diffuse naturally, achieving better penetration and coverage with reduced substance consumption.
2Reliability
If large quantities of washing liquid are heated, then washing effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent changes the thermal parameters by heating only the small quantity of detergent solution needed for nebulization rather than large volumes of washing liquid. The ultrasonic nebulizer requires minimal liquid volume, so heating this small amount significantly reduces energy consumption while maintaining washing effectiveness through the enhanced distribution of the heated detergent aerosol.
3Reliability
If more detergent is used to improve cleaning of hard-to-reach areas, then cleaning efficacy is improved, but environmental pollution and cost increase
Solution Approach 1:
The patent replaces conventional mechanical spraying with ultrasonic nebulization, which generates fine aerosol particles that naturally diffuse and penetrate into hard-to-reach areas of dishes. This substitution improves detergent distribution efficiency, allowing reduced detergent quantities to achieve the same or better cleaning efficacy, thereby reducing environmental pollution and costs.
Solution Approach 2:
The patent changes the particle size parameter of the detergent delivery system by converting liquid detergent into fine aerosol particles through ultrasonic nebulization. This parameter change enhances the penetration capability and distribution uniformity of the detergent, improving cleaning efficacy in hard-to-reach areas while reducing the total amount of detergent required.
