Volatile Substance Diffuser With Threadless Wick Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for diffusing volatile substances face issues with incompatible opening and regulation movements, limited airflow due to external threads, and inadequate wick exposure adjustment, leading to inefficient evaporation.
Innovation Solution
A device with a container and upper closing element connected by a threadless neck groove, allowing lateral movement for wick adjustment, enabling precise control of evaporation through defined positions and improved airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an external thread is used to connect the container and upper element, then the connection is robust, but air flow is blocked and evaporation is limited
Solution Approach 1:
The connection system is divided into two independent parts: an internal thread for robust closure and a threadless neck groove for air flow. This segmentation allows the closing function and ventilation function to operate independently without interfering with each other.
Solution Approach 2:
The external thread is removed from the design. Instead, only an internal thread within the upper element and a threadless neck groove on the container are used. This extraction eliminates the air flow blockage caused by external threads while maintaining connection strength through the internal threading system.
2Reliability
If the upper element is fixed to prevent opening, then security is improved, but adjustment of wick exposure is prevented
Solution Approach 1:
The upper element is designed with dynamic characteristics, allowing it to be securely closed through internal threading while simultaneously enabling easy opening and adjustment movements. The element can transition between a fixed closed state and a movable adjustment state.
Solution Approach 2:
The functions of secure closure and adjustable regulation are separated into different mechanical mechanisms: internal threading provides secure closure, while the threadless neck groove interface enables independent adjustment movements.
3Device complexity
If the opening movement and regulation movement are combined, then device complexity is reduced, but the movements become incompatible
Solution Approach 1:
The device separates opening/closing movements from regulation movements by using distinct mechanical interfaces: internal threading handles opening/closing while the threadless neck groove handles regulation, allowing both functions to operate independently and compatibly.
Solution Approach 2:
The external thread is removed to eliminate the conflict between opening movement and regulation movement. This allows the upper element to move laterally for adjustment without interfering with the opening/closing function.
4Strength
If the internal space around the wick is enclosed, then structural integrity is improved, but air flow and evaporation are limited
Solution Approach 1:
The container structure has different properties in different locations: the body maintains enclosed structural integrity while the neck region features a threadless groove that creates localized air flow channels, providing both strength and evaporation efficiency.

Implementation Method 1
a wick (3) jointed to the closing element (2), which is soaked with the liquid volatile substance
Implementation Method 2
the lower end of the wick (3) protrudes into the liquid, while the upper end protrudes from the liquid and from the container (1)... diffuses its scent or any other features to the air space surrounding the device
Implementation Method 3
diffuses its scent or any other features to the air space surrounding the device

AI summary
Device for diffusing volatile substances that comprises a container (1), an upper closing element (2) which closes the opening of the container (1) and a wick (3) jointed to the closing element (2). The container (1) comprises an opening, a reservoir containing a predetermined volume of a liquid volatile substance, and a lower neck (6). The closing element (2) further comprises at least one internal perimetral grove (4), and the lower neck (6) of the container (1) further comprises a groove with no thread pitch (7) in turn comprising protrusions (9) so that the internal perimetral grove (4) and the groove with no thread pitch (7) work together for an adjustment on a fixed pre-determined position of the upper closing element (2) with regards to the container (1).
