Variable-Diameter Cleaning Assembly for Aerosol Provision Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices face issues with residue buildup on internal surfaces, leading to reduced performance, unpleasant taste, and inadequate air flow due to uncleaned heating chambers and tubes.
Innovation Solution
A cleaning assembly with dual or multiple cleaning elements of varying diameters and materials, impregnated with cleaning fluid, designed to effectively clean internal surfaces of aerosol provision devices, including heating chambers and tubes, with a protective outer casing to maintain integrity and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cleaning element is used, then the device structure is simple, but it cannot effectively clean surfaces with varying diameters and geometries
Solution Approach 1:
The cleaning assembly is divided into multiple cleaning elements (first cleaning element and second cleaning element) with different diameters and geometries. Each element is specifically designed to clean different surfaces within the aerosol provision device, such as the heating chamber and tube, allowing effective cleaning of diverse surfaces without requiring a single complex adaptable element
Solution Approach 2:
The cleaning assembly functions as a multi-functional tool by incorporating multiple cleaning elements that can address various cleaning needs within a single device. The first cleaning element cleans the heating chamber while the second cleaning element cleans the tube, making the assembly universally effective for cleaning multiple different surfaces and geometries
2Reliability
If cleaning elements are exposed without protection, then cleaning access is easy, but the cleaning elements can be damaged or contaminated before use
Solution Approach 1:
The cleaning elements are nested within a protective outer casing that encloses them before use. The casing can be opened to expose the cleaning elements when needed, providing both protection during storage and transport, and easy access when the cleaning operation is required. This nested structure prevents damage and contamination while maintaining user-friendly accessibility

AI summary
Cleaning assemblies for aerosol provision devices are disclosed. In one example a cleaning assembly comprises: a shaft defining a longitudinal axis; and a cleaning element disposed at an end of the shaft. The cleaning element comprises a proximal portion and a distal portion adjacent to the proximal portion. The proximal portion has a greater cross section in the direction perpendicular to the longitudinal axis of the shaft than the distal portion. In another example, an aerosol provision device cleaning assembly comprises: a shaft; a first cleaning element disposed at a first end of the shaft; and a second cleaning element disposed at a second end of the shaft. The first cleaning element is larger than the second cleaning element
