Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aroma therapy and atomization systems are cumbersome, heavy, and lack integration, stability, and control over droplet size, making them inefficient and aesthetically unpleasing, with a high risk of spills and material waste.
Innovation Solution
A compact, integrated system with a pump-driven eductor and separator that atomizes liquids into a fine mist by using an oscillating motor to draw liquids from a reservoir and separate droplets by size, allowing for control over the atomization process and minimizing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a pump is used to atomize liquid, then atomization capability is improved, but weight increases
Solution Approach 1:
The patent merges the pump, reservoir, and atomizer into a single integrated unit. The pump housing serves as both the pump body and the reservoir container, eliminating the need for separate components. This integration reduces the overall weight while maintaining the atomization function through the integrated pump mechanism that draws liquid from the same housing.
2Quantity of substance
If a separate reservoir is used, then storage capacity is improved, but device complexity increases
Solution Approach 1:
The reservoir is merged with the pump housing, forming a single integrated component. The pump housing is designed to serve dual purposes: as the pump body that drives atomization and as the reservoir that stores the liquid. This eliminates the need for separate reservoir connections and reduces system complexity while maintaining adequate storage capacity.
3Productivity
If a large spray head is used, then atomization efficiency is improved, but footprint increases
Solution Approach 1:
The atomizer nozzle is nested within the pump housing structure. The pump housing is designed with an integrated nozzle assembly that fits inside its own body, creating a compact configuration. This nesting approach allows for efficient atomization without requiring a large external footprint, as the spray head is contained within the housing rather than extending outward.
4Stability of the object's composition
If integration is implemented, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The pump, reservoir, and atomizer are merged into a single integrated unit that can be manufactured as one piece or pre-assembled module. This integration provides stability by creating a unified structure with a fixed center of gravity, preventing tipping and ensuring consistent operation. The integrated design simplifies manufacturing by reducing the number of separate assembly steps and connection points.
5Loss of substance
If droplet separation is implemented, then material efficiency is improved, but device complexity increases
Solution Approach 1:
The patent uses pneumatic principles within the pump housing to separate droplets of different sizes. The pump creates air flow patterns that naturally separate larger droplets from smaller ones, allowing larger droplets to fall back into the reservoir while smaller droplets are expelled into the atmosphere. This pneumatic separation mechanism improves material efficiency by recovering larger droplets without requiring complex mechanical separation devices.

Function Achieved in This Case
The system provides a stable, aesthetically pleasing, and efficient method for distributing fragrances or essential oils, reducing droplet size and material usage while minimizing spills and waste, with adjustable control over the atomization process.
Implementation Method 1
a pump driven by an oscillating motor to draw liquids from a reservoir and distribute them through an eductor into the atmosphere
Implementation Method 2
a separator after the eductor relies on direction change and momentum of impact to further comminute the droplets into a more finely atomized mist
Implementation Method 3
a separator after the eductor relies on direction change and momentum of impact to further comminute the droplets into a more finely atomized mist, while separating out comparatively larger droplets

AI summary
An atomizer provides a control of duty cycle or a motor driving a diaphragm pump. By providing precise, high-speed flow through an eductor nozzle, improved atomization occurs. However, to control the total volume of atomized liquid discharged, the delay time between operational time periods may also be controlled. Thus, a very effective atomizer provides economical use of essential oils by control duty cycle. Precision modeling provides highly integrated subsystems providing superior performance and reliability.
