Modified Liquid Electrical Vaporiser Chimney for Uniform Fragrance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid electrical vaporisers take time to reach steady state emanating conditions and often distribute fragrance unevenly, leading to consumer confusion and wall staining.
Innovation Solution
Incorporating a distal chimney extension angled away from the vertical plane and optionally featuring a convex inner surface, which redirects active-laden air away from the wall and into the room, utilizing the Coanda effect for faster and more uniform distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standard vertical chimney is used, then the device structure is simple, but the fragrance distribution is uneven and walls are stained
Solution Approach 1:
The chimney is designed with an asymmetric structure including a distal extension that protrudes from the side of the housing away from the plug. This asymmetric configuration redirects the fragrance plume away from the wall, preventing staining while maintaining manufacturing simplicity
Solution Approach 2:
The chimney extends not only vertically but also horizontally in the distal direction, adding a third dimensional component to the fragrance discharge path. This multi-dimensional approach directs fragrance into the room space rather than allowing it to contact the wall
2Object-affected harmful factors
If the chimney is extended distally, then fragrance distribution uniformity improves, but device complexity increases
Solution Approach 1:
The chimney is segmented into distinct functional portions: a vertical portion for structural support and a distal extension portion for fragrance redirection. This segmentation allows each portion to be optimized independently while maintaining overall simplicity
Solution Approach 2:
The distal extension serves multiple functions simultaneously: it acts as a structural component of the chimney, a flow director for fragrance, and a spacer to maintain distance from the wall. This multi-functionality reduces the need for additional components
3Reliability
If the device operates from cold state, then it can eventually provide steady emanation, but it takes considerable time to reach ideal conditions
Solution Approach 1:
The distal extension is pre-configured to optimize fragrance flow dynamics from the moment the device operates. By establishing the correct flow path geometry in advance, the system accelerates the transition to steady-state emanation without requiring additional heating time
