Solution Overview

Problem

Existing electrostatic atomizers for liquids face challenges in ensuring reliable emptying of the liquid tank and efficient supply to the atomizer nozzles without requiring pressure-generating components, while also being cost-effective.

Innovation Solution

The electrostatic atomizer design incorporates a delivery device between the liquid tank and the nozzles, connected by one-piece extruded plastic hoses, which acts as a passive component, eliminating the need for pressure-generating parts and allowing for low-cost production of the liquid tank, with each nozzle having a separate hose and a multi-channel hose pump for efficient liquid delivery.

Engineering Contradictions & Design Principles

Solution Approach 1:

Traditional mechanical pressure-generating components are replaced with an integrated delivery device that uses the liquid tank's own structure and electrostatic atomization principles to achieve liquid delivery. This substitution eliminates complex mechanical pumps while maintaining effective liquid supply through the atomizer nozzles.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the operating parameters by eliminating the need for high pressure generation. Instead, it uses controlled liquid flow through the integrated delivery device combined with electrostatic field effects at the nozzles to achieve efficient atomization and delivery without traditional pressure-mechanical components.
