Porous Wick Fragrance Diffuser for Blockage-Free Dripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance diffusers require separate mechanisms for diffusion and dripping, which can be prone to blockages with fatty products and are influenced by air pressure equilibrium between bottles, complicating the drop-by-drop dripping process.
Innovation Solution
A fragrance diffusion device featuring a porous wick that extends between two opposing walls, with air intake openings allowing external air to compensate for fragrance flow, dissociating air pressure from the dripping mechanism and eliminating the need for small holes that can block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate mechanisms are used for diffusion and dripping functions, then the diffusion effect is achieved, but the device complexity increases and the dripping mechanism becomes prone to blockages
Solution Approach 1:
The patent combines the diffusion and dripping functions into a single porous wick component. The wick simultaneously performs fragrance absorption and diffusion while maintaining controlled dripping, eliminating the need for separate mechanisms and reducing structural complexity while improving reliability
Solution Approach 2:
The porous wick serves multiple functions: it absorbs fragrance from the upper bottle, diffuses it through its porous structure, and controls drop-by-drop dripping to the lower bottle. This multi-functional design simplifies the overall device structure while ensuring reliable operation
2Reliability
If small holes are used for drop-by-drop dripping, then the dripping control is achieved, but the holes become blocked by fatty products in fragrance compositions
Solution Approach 1:
The patent uses a porous wick material with controlled porosity to replace small holes for dripping. The porous structure provides multiple pathways for liquid flow, preventing blockage by fatty products while maintaining drop-by-drop control through capillary action and surface tension effects
3Stability of the object's composition
If bottles communicate via air-passage and flow tubes, then pressure equilibrium is established, but the pressure influence affects the drop-by-drop dripping function
Solution Approach 1:
The patent extracts the air passage function from the dripping mechanism by introducing separate air intake openings in the walls. This allows air to enter the cavity independently, establishing pressure equilibrium without interfering with the fragrance flow and dripping function through the porous wick
4Device complexity
If a single wick performs both diffusion and dripping functions, then the device is simplified, but the wick must handle multiple functions simultaneously
Solution Approach 1:
The porous wick is designed to perform multiple functions simultaneously: absorbing fragrance, diffusing it through its porous structure, and controlling drop-by-drop dripping. The material properties and structural design enable this multi-functionality while simplifying the overall device
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the diffusion and dripping process, preventing blockages and ensuring consistent drop-by-drop delivery independent of air pressure equilibrium between bottles.
Implementation Method 1
at least one wick made of porous material which extends in the cavity along the longitudinal axis passing through the two walls via its two respective opposite ends which each project into an external zone adjacent to the relevant wall
Implementation Method 2
said at least one wick becomes impregnated with fragrance and thus both diffuses fragrance (situated above the device, notably in an upper bottle) into the cavity and to the outside
Implementation Method 3
the intake air that compensates for the volume of fragrance flowing through said at least one wick comes from outside the device

AI summary
A Fragrance diffusion system is provided having a diffusion device which has two opposing walls spaced apart from one another, at least one wick, and at least one air intake. An upper first bottle has a first neck the opening of which is positioned facing one of the two opposing walls referred to as the upper wall, a lower second bottle having a second neck the opening of which is positioned facing the other wall referred to as the lower wall. The upper first bottle has the fragrance which, by impregnating the wick, on the one hand causes the fragrance to diffuse into the cavity and to outside of the device via said at least one opening, and on the other hand causes dripping drop by drop into the lower second bottle. The lower second bottle having a capacity which is dimensioned so that the level of the liquid transferred into said lower second bottle is situated below a lower end of the wick.
