Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices suffer from stuck-on residue formation on heating elements, leading to reduced cleanliness and compromised smoking quality due to burnt taste, and difficulty in inserting and removing heating elements.
Innovation Solution
Incorporating a vibration part to vibrate the heating element, controlled by a controller based on predetermined conditions such as time, temperature, and puff detection, to prevent and remove residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating element is used to heat the aerosol-generating article, then aerosol generation is enabled, but stuck-on residue forms on the heating element surface
Solution Approach 1:
The patent applies mechanical vibration to the heating element surface to prevent stuck-on residue formation. The vibration part generates vibrations that disrupt the adhesion between the aerosol-generating article and the heating element, effectively preventing residue from bonding to the heated surface while maintaining the necessary heating temperature for aerosol generation.
2Reliability
If the heating element is held firmly in the aerosol-generating article, then heating stability is improved, but insertion and removal become difficult
Solution Approach 1:
The vibration part is activated during the insertion and removal processes to reduce friction and adhesion forces between the heating element and the aerosol-generating article. This temporary vibration assistance enables easy insertion and removal while the heating element maintains stable positioning during the heating operation when vibration is not active.
3Device complexity
If the holder structure is simple, then device complexity is reduced, but the holder cannot prevent residue formation in the inner space
Solution Approach 1:
The vibration part generates vibrations that extend into the inner space of the holder, preventing aerosol-generating article material from adhering to the holder walls and internal surfaces. This vibration-based prevention mechanism adds minimal structural complexity while effectively eliminating residue accumulation in the holder's inner space.
