Vibrating Heating Element for Cleaner Aerosol Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices fail to prevent the formation of fixed matter on heating elements, leading to reduced cleanliness and compromised smoking quality due to burnt tastes, and struggle with ease of insertion and removal of heating elements.
Innovation Solution
Incorporating a vibration part to vibrate the heating element vertically, controlled by a controller based on conditions such as time, temperature, and puff detection, to prevent and remove fixed matter, enhancing cleanliness and ease of insertion/removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a heating element is used to heat the cigarette, then aerosol generation is achieved, but fixed matter forms on the heating element reducing cleanliness and causing burnt taste
Solution Approach 1:
The patent applies mechanical vibration to the heating element through a vibration unit that generates oscillating movements. This vibration prevents fixed matter from adhering to the heating element surface by disrupting the bonding between tobacco residues and the heating surface, thereby eliminating burnt taste while maintaining aerosol generation capability
Solution Approach 2:
The patent converts the harmful fixed matter formation into a beneficial self-cleaning mechanism. By allowing fixed matter to form and then using vibration to detach it, the system transforms the accumulation problem into a controlled removal process that maintains heating element cleanliness and prevents burnt taste
2Device complexity
If the holder simply guides insertion and removal of the cigarette, then the structure is simple, but residues remain in the inner space and on components
Solution Approach 1:
The holder is transformed from a simple guiding structure into a multi-functional component that not only guides cigarette insertion and removal but also actively participates in residue removal. The holder works in conjunction with the vibration unit to detach and remove fixed matter from the heating element and inner space surfaces
3Stability of the object's composition
If the heating element is fixed firmly to prevent movement, then heating stability is improved, but ease of insertion and removal is reduced
Solution Approach 1:
The vibration unit generates oscillating movements in the heating element that facilitate insertion and removal by reducing friction and breaking adhesive bonds. During normal operation, the heating element maintains sufficient stability, while during insertion/removal phases, vibration assists smooth movement without compromising overall system stability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The vibration part effectively prevents fixed matter formation, improves device cleanliness, and enhances smoking quality by mitigating burnt tastes, while facilitating easy insertion and removal of the heating element.
