Engineering Contradiction Analysis
1Object-generated harmful factors
If burning method is used to generate aerosol, then aerosol generation is achieved, but harmful combustion products are produced
Solution Approach 1:
The patent replaces the thermal combustion mechanism with an inductive heating mechanism. The heating element generates heat through electromagnetic induction when exposed to an alternating magnetic field, vaporizing the aerosol-generating material without combustion. This substitution eliminates harmful combustion products while maintaining aerosol generation capability.
Solution Approach 2:
The patent changes the heating parameter from high-temperature combustion to controlled inductive heating. By adjusting the frequency and power of the alternating magnetic field, the material is vaporized at optimal temperatures for aerosol generation without reaching combustion thresholds, thus eliminating harmful byproducts.
2Productivity
If heating method is used to generate aerosol, then combustion is avoided, but aerosol generation efficiency is insufficient
Solution Approach 1:
The patent employs inductive heating instead of conventional thermal heating. The heating element, when exposed to an alternating magnetic field, generates heat through electromagnetic induction, providing more efficient and controllable heating that enhances aerosol generation efficiency without excessive temperature rise.
Solution Approach 2:
The patent uses periodic alternating magnetic fields to generate heat in the heating element. This periodic action allows for controlled heat generation, enabling efficient aerosol vaporization while preventing temperature runaway, thus optimizing both efficiency and temperature control.
3Productivity
If seal is added to isolate air path, then aerosol generation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs a flexible seal element that forms an airtight barrier between the heating zone and the external environment. This flexible sealing mechanism isolates the air path, preventing leakage and improving aerosol generation efficiency while adding minimal structural complexity compared to rigid sealing systems.
