Conventional heat-not-burn electronic vaporizers face issues with residue buildup on heating bodies, making them difficult to clean and affecting the inhalation taste due to contact heating methods.
Innovation Solution
An aerosol-generation article that generates heat under an alternating electric field, eliminating the need for a heating body in the vaporizer and allowing for easier cleaning and improved taste, comprising a solid substrate with polar molecules and a heating-assisting material, and an electronic vaporizer with a power source and alternating electric field generation module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact heating technology is used with an external heating body, then heating function is achieved, but residues are easily adhered to the heating layer making it hard to clean and affecting inhalation taste
Solution Approach 1:
The patent extracts and removes the external heating body from the system. Instead of using a separate heating element that contacts the aerosol-generation article, the article itself is made electromagnetically inducible and generates heat internally when placed in an alternating magnetic field. This eliminates the heating body that would otherwise accumulate residues and require cleaning.
Solution Approach 2:
The patent replaces the mechanical contact heating system with an electromagnetic induction heating system. The external heating body that physically contacts the article is substituted with an electromagnetic field that induces current within the article material itself, causing internal heat generation without mechanical contact. This substitution eliminates the residue adhesion problem associated with contact heating surfaces.
2Ease of manufacture
If contact heating technology is used, then heating function is achieved, but the heating body requires frequent cleaning and maintenance
Solution Approach 1:
The patent extracts the heating function from the separate heating body and transfers it to the aerosol-generation article itself. By making the article electromagnetically inducible, the article becomes self-heating, eliminating the need for a maintainable heating body component in the vaporizer device.
Solution Approach 2:
The aerosol-generation article is designed to be self-heating through electromagnetic induction. When placed in the alternating magnetic field generated by the vaporizer, the article's inducible material generates heat internally without requiring an external heating element. This self-service heating mechanism eliminates maintenance requirements for heating bodies.
3Productivity
If high temperature pyrolysis is used, then vaporization efficiency is improved, but harmful substances are generated
Solution Approach 1:
The patent changes the heating parameter control by using electromagnetic induction heating which allows for precise temperature control through adjustment of the alternating magnetic field frequency and intensity. This enables heating to optimal vaporization temperatures without exceeding them, preventing pyrolysis and harmful substance generation while maintaining vaporization efficiency.
