Solution Overview
Problem
Current fragrance diffusers lack customization options for blending essential oils and do not efficiently manage the mixing and vaporization of fragrant liquids, leading to potential cross-contamination and limited user control over fragrance delivery.
Innovation Solution
A fragrance diffuser system with a reservoir, docking stations, a droplet delivery system, and a vaporizer that allows for customizable blending and mixing of essential oils with a foundation liquid, featuring a piezoelectric device for atomization and a duct for controlled vapor release, along with a mobile app for user control and cleaning cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If essential oils are manually mixed and vaporized in conventional diffusers, then the device structure remains simple, but fragrance customization and blending precision are limited
Solution Approach 1:
The system segments the fragrance delivery process into separate functional modules: a reservoir for foundation liquid, multiple docking stations for different essential oils, a droplet delivery system for precise dispensing, and a vaporizer for atomization. This segmentation allows independent optimization of each component while enabling complex blending capabilities through coordinated operation of the modular units.
Solution Approach 2:
The droplet delivery system acts as an intermediary mechanism between the essential oil containers and the vaporizer. It precisely controls the transfer of fragrant liquid drops to the foundation liquid in the reservoir, enabling accurate blending ratios without requiring complex manual mixing procedures or direct exposure of essential oils to heat.
2Adaptability or versatility
If multiple essential oils are mixed in a single reservoir, then blending flexibility increases, but cross-contamination risk increases
Solution Approach 1:
The system maintains separate storage compartments for different essential oils at the docking stations and uses individual droplet delivery pathways for each oil type. This segmentation prevents cross-contamination between different essential oil containers while still allowing them to be combined in the reservoir during operation.
Solution Approach 2:
The essential oils are extracted from their sealed container environments and delivered as controlled droplets only when needed for vaporization. The droplet delivery system isolates the fragrant liquids from direct contact with the foundation liquid reservoir until the moment of dispensing, minimizing contamination risk while enabling flexible blending.
3Productivity
If manual cleaning of diffuser components is required, then device simplicity is maintained, but cleaning efficiency and hygiene standards are insufficient
Solution Approach 1:
The vaporizer element is designed to be easily removable from the diffuser assembly, allowing users to independently clean and maintain this critical component without disassembling the entire device or requiring special cleaning tools. The modular design enables self-service cleaning that maintains hygiene standards while adding minimal complexity to the overall system.
4Manufacturing precision
If precise droplet control is implemented, then fragrance dosing accuracy improves, but device complexity increases
Solution Approach 1:
The droplet delivery system replaces complex mechanical dosing mechanisms with a simpler droplet-based transfer method. By using controlled droplet dispensing rather than volumetric pumping or complex metering mechanisms, the system achieves precise fragrance dosing through the natural properties of liquid droplets while maintaining relatively simple device architecture.

AI summary
Methods and devices for atomizing a fragrant liquid are disclosed. A reservoir receives a volume of a base liquid. One or more drops of a substance are added to the base liquid to form a volume of an aromatic liquid. A vaporizer atomizes the aromatic liquid, forming a mist that is emitted from the device. The device allows a user to customize the blend of substances that are used to form the aromatic liquid.
