Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fibrous susceptor material is used for heating aerosol-generating material, then heating efficiency and aerosol production are improved, but the device complexity increases
Solution Approach 1:
The patent applies composite materials by combining fibrous susceptor material (metal or carbon fibers) with aerosol-generating material in a single composition. This composite structure enables the material to both generate aerosol and efficiently transfer heat through the susceptor's high thermal conductivity and inductive heating properties, thereby improving aerosol production efficiency while managing the complexity through integrated design
Solution Approach 2:
The fibrous susceptor material is designed with porous or fibrous structure that allows permeation of heating energy and facilitates rapid heat transfer throughout the composition. The porous nature of the fibrous material increases surface area for heat transfer and enables efficient aerosol generation while maintaining structural integrity
2Speed
If inductive heating is used to heat the susceptor material, then heating speed and efficiency are improved, but energy consumption increases
Solution Approach 1:
The patent replaces conventional resistive or conductive heating mechanisms with inductive heating technology. The fibrous susceptor material contains metal or carbon fibers that can be directly heated by electromagnetic induction, enabling rapid heating through electromagnetic field interaction rather than conventional thermal conduction, thus improving heating speed while potentially reducing overall energy consumption through more efficient energy transfer
Solution Approach 2:
The patent utilizes the electromagnetic parameters of metal or carbon fibers within the fibrous susceptor material to enable inductive heating. By selecting materials with appropriate electrical conductivity and magnetic properties, the system optimizes the interaction with electromagnetic fields to achieve rapid heating with efficient energy utilization
