Solution Overview
Problem
Existing air diffusion devices for volatile compounds, such as fragrances, suffer from non-uniform diffusion and limited area coverage, leading to uneven scent distribution and concentration hotspots.
Innovation Solution
The device incorporates a casing with an air circulation circuit featuring three fluidly independent chambers, each connected to its own air outlet, and a substrate movement path for easy maintenance, ensuring uniform diffusion and wide-area coverage by increasing the section of chambers downstream and using a guide rail for substrate handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air outlet is used in the diffusion device, then the device structure is simple, but the diffusion is non-uniform and concentration hotspots occur
Solution Approach 1:
The single air outlet is divided into multiple air outlets (first, second, and third air outlets) arranged at different positions and orientations. Each outlet is connected to the reception area through separate pathways, enabling air to be discharged in multiple directions simultaneously. This segmentation transforms the concentrated single-point discharge into distributed multi-point discharge, achieving uniform diffusion across the diffusion surface without creating concentration hotspots.
2Volume of moving object
If the air outlet section is small, then the device compactness is improved, but the volatile substance accumulation is insufficient for adequate diffusion
Solution Approach 1:
The air outlets are extended into elongated slots rather than simple circular openings. The first air outlet extends along the first side wall, the second air outlet extends along the second side wall, and the third air outlet extends along the third side wall. This dimensional extension increases the effective discharge area and volatile substance release capacity without significantly increasing the overall device volume, maintaining compactness while achieving adequate substance accumulation and diffusion.
