Scent Retaining Structure With Segmented Ventilation Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing scent providing devices face an issue with increased ventilation resistance due to the lack of separation between the air flow area and the perfume retainer area in the containment portion, leading to decreased flow velocity and flow rate of the released scent.
Innovation Solution
A perfume retaining structure is designed with a retaining space that includes a ventilation area and a retaining area, where the perfume retainer is positioned. This structure features first and second openings that allow the retaining space to be opened to the outside, with the ventilation area facing these openings and the retaining area adjacent to it, communicating with the ventilation area. The structure also includes ribs that limit the movement of the perfume retainer towards the ventilation area, thereby reducing ventilation resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air flow area and perfume retainer area are not separated in the containment portion, then the structure is simple, but the ventilation resistance increases and the flow rate of released scent decreases
Solution Approach 1:
The containment portion is divided into a ventilation area and a retaining area by a partition wall. The ventilation area is configured to allow air flow from the communication hole to the releasing portion, while the retaining area houses the perfume retainer. This segmentation prevents the perfume retainer from obstructing the air flow path, thereby reducing ventilation resistance and maintaining high flow rate of released scent while keeping the overall structure relatively simple.
2Productivity
If the ventilation area is separated from the retaining area, then the ventilation resistance decreases, but the device complexity increases
Solution Approach 1:
A partition wall is introduced to separate the containment portion into ventilation area and retaining area. This segmentation creates dedicated air flow paths that reduce ventilation resistance. The partition wall is designed to be integrated into the containment portion structure, minimizing additional complexity while achieving effective separation of functions.
Solution Approach 2:
The partition wall is strategically positioned to separate only the necessary areas for air flow and perfume retention. The design applies local quality by creating specific flow channels and retention zones within the containment portion, allowing air to flow freely through the ventilation area while keeping the perfume retainer confined to the retaining area, thus reducing ventilation resistance without unnecessarily complicating the entire device structure.
