VOC-Free Mist Ejector for Essential Oil Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common aerosol cans emit volatile organic compounds (VOCs) that pose health risks and contribute to air pollution, necessitating alternative solutions that do not rely on VOCs.
Innovation Solution
An apparatus comprising a flexible housing with removable components, reservoirs for substances like essential oils, and an ejector system that mixes and ejects substances without using VOCs, featuring a cover, flow port, and ejector for mist-like ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If common aerosol cans are used to eject substances, then ejection efficiency is improved, but harmful VOCs are released into the atmosphere
Solution Approach 1:
The patent changes the chemical composition parameters of the ejectable substance from VOC-based propellants to essential oil-based formulations. This parameter change maintains the ejection function while eliminating harmful emissions, directly resolving the contradiction between productivity and harmful factors.
Solution Approach 2:
The patent creates an inert environment by replacing reactive VOCs with natural essential oils that do not contribute to air pollution. This substitution maintains the aerosol ejection mechanism while establishing a harmless atmospheric environment, addressing the contradiction between efficient ejection and harmful emissions.
2Object-generated harmful factors
If essential oils are used instead of VOCs, then harmful emissions are reduced, but ejection performance may be compromised
Solution Approach 1:
The patent converts the potential limitation of essential oils into a benefit by utilizing their natural aromatic properties and volatility characteristics. The essential oils, while different from VOCs, provide effective ejection performance combined with therapeutic and aromatic benefits, thus converting a perceived disadvantage into an advantage that maintains productivity while reducing harm.
Solution Approach 2:
The patent employs composite formulations combining essential oils with carrier substances to optimize ejection performance. This composite approach ensures that the natural essential oils achieve adequate spray characteristics and delivery efficiency, resolving the contradiction between using harmless substances and maintaining ejection performance.
3Ease of operation
If a flexible housing with removable components is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent divides the housing into flexible upper and lower portions with removable components, allowing users to access internal reservoirs and replace substances easily. This segmentation improves ease of operation by enabling user-friendly maintenance while the flexible material provides structural integrity, effectively managing the trade-off between accessibility and structural complexity.
