Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning methods for aerosol-generating devices risk damaging the fragile heating element due to unintentional rotation during residue removal, particularly in devices with flat heating blades.
Innovation Solution
A cleaning tool with a rotatably attached handle and main body, featuring a bearing mechanism to prevent rotation of the main body during insertion, combined with elastic cleaning elements that scrape off residues without damaging the heating element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning tool allows free rotation of the handle during insertion, then the ease of operation is improved, but the heating element may be damaged due to unintentional rotation of the main body
Solution Approach 1:
The cleaning tool is divided into two independently rotatable segments: the handle and the main body. The handle can rotate freely for ease of insertion, while the main body remains rotationally constrained to prevent damage to the heating element. This segmentation allows each part to have different rotational characteristics.
Solution Approach 2:
A bearing mechanism serves as an intermediary between the handle and main body. This bearing allows the handle to rotate independently while preventing rotational transmission to the main body, thus mediating between the need for easy operation and the need to prevent damage.
2Stability of the object's composition
If the main body is firmly attached to the handle, then the structural stability is improved, but the handle cannot rotate independently which impairs ease of operation
Solution Approach 1:
The connection between the handle and main body is made dynamic rather than static. The bearing mechanism allows relative rotation between the handle and main body during operation, providing the necessary flexibility for ease of insertion while maintaining structural integrity for stable cleaning action.
3Productivity
If the cleaning elements are rigid, then the cleaning effectiveness is improved, but the heating element may be damaged due to excessive force
Solution Approach 1:
The cleaning elements are designed with elastic properties, changing the mechanical parameter from rigid to flexible. This allows the cleaning elements to maintain sufficient cleaning effectiveness while adapting to the fragile heating element geometry and preventing damage through controlled deformation.
Solution Approach 2:
The elastic cleaning elements provide beforehand cushioning by deforming under load to absorb excessive forces before they can damage the heating element. This protective cushioning effect occurs automatically during the cleaning process.

Function Achieved in This Case
Effectively cleans the heating element while preventing damage by allowing translational movement without rotational force, ensuring the heating element's integrity is maintained.
Implementation Method 1
The handle is rotatably attached to the main body of the cleaning tool, thereby preventing rotation of the main body during insertion into the heating chamber
