Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional combustion methods are used to create smoke, then smoke generation is achieved, but combustion occurs which is undesirable in heat-not-burn products
Solution Approach 1:
The patent replaces the thermal field of combustion with a magnetic field-based heating system. A varying magnetic field penetrates the smokable material directly, inducing eddy currents and hysteresis heating without requiring chemical combustion, thus eliminating harmful combustion byproducts while achieving efficient volatilization.
Solution Approach 2:
The patent changes the fundamental heating parameter from combustion temperature (uncontrolled high temperature) to controlled magnetic field-induced heating at lower temperatures. By adjusting magnetic field frequency and intensity, the heating parameters can be precisely controlled to achieve volatilization without combustion.
2Object-affected harmful factors
If heat-not-burn products are used to avoid combustion, then combustion is eliminated, but efficient and cost-effective heating methods are lacking
Solution Approach 1:
The patent replaces complex thermal management systems required for controlled heating with a direct magnetic field penetration system. This substitution simplifies the heating mechanism, reduces manufacturing complexity, and improves cost-effectiveness while maintaining the no-combustion advantage.
3Productivity
If magnetic field penetration heating is used, then rapid and continuous volatilization is achieved, but the system complexity increases
Solution Approach 1:
The patent employs a varying magnetic field system that serves multiple functions simultaneously: heating the smokable material, enabling rapid volatilization, and requiring no additional mechanical moving parts. This multi-functionality achieves high productivity without proportionally increasing system complexity.
