Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional heating methods are used in non-combustible aerosol provision systems, then the system structure remains simple, but heat distribution across the aerosol generating material is inefficient and inconsistent
Solution Approach 1:
A heat transfer material is introduced as an intermediary component between the heat source and the aerosol generating material. This material conducts heat from the heating element throughout the aerosol generating material, ensuring uniform temperature distribution and consistent aerosol generation without requiring complex heating structures.
Solution Approach 2:
The aerosol provision system employs composite material construction by combining the heat transfer material with the aerosol generating material. This composite structure allows the heat transfer material to be integrated directly into the aerosol generating component, enabling efficient heat distribution while maintaining system simplicity.
2Productivity
If heat transfer material with high thermal conductivity is used, then heat distribution efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent specifies a minimum thermal conductivity parameter of 220 W/mK for the heat transfer material, allowing manufacturers to select materials meeting this criterion without requiring complex integration processes. This parameter-based approach simplifies manufacturing by providing a clear material selection criterion rather than requiring complex structural designs.
Solution Approach 2:
The heat transfer material can be implemented as discrete portions or a continuous matrix within the aerosol generating material. This segmentation approach allows for flexible manufacturing methods, where the heat transfer material can be added as separate components or mixed into the aerosol generating material during the manufacturing process.
3Stability of the object's composition
If heat transfer material is added to the aerosol generating material, then temperature uniformity is improved, but the weight of the article increases
Solution Approach 1:
The heat transfer material can be implemented in a porous or matrix form that is integrated into the aerosol generating material structure. This approach allows the heat transfer material to occupy space within the existing structure rather than adding significant external mass, thereby improving temperature uniformity with minimal weight increase.
Solution Approach 2:
By combining the heat transfer material with the aerosol generating material to form a composite structure, the patent ensures that the heat transfer material becomes part of the overall material matrix. This integration minimizes the additional weight compared to adding separate heat transfer components, while achieving uniform temperature distribution throughout the aerosol generating material.
