Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electrically heated smoking devices are used to avoid combustion, then harmful combustion products are reduced, but performance consistency deteriorates and battery size increases
Solution Approach 1:
A thermally conductive member is introduced as an intermediary between the heating element and the aerosol-forming material. This mediator efficiently transfers heat from the heating element to the material, ensuring consistent heating performance and reliable aerosol generation without requiring excessive battery power.
Solution Approach 2:
The thermally conductive member can be constructed from composite materials such as metal foam, ceramic foam, or carbon-based structures. These composite materials provide both high thermal conductivity for efficient heat transfer and appropriate structural properties to maintain consistent performance while managing battery requirements.
2Object-affected harmful factors
If electrically heated smoking devices are used to avoid combustion, then harmful combustion products are reduced, but battery capability requirements increase
Solution Approach 1:
The thermally conductive member acts as an efficient heat transfer intermediary, reducing energy losses and improving heating efficiency. This allows the system to achieve the required heating performance with lower battery capability, extending operational duration without increasing battery size.
Solution Approach 2:
By changing the thermal conductivity parameter of the system through the introduction of the thermally conductive member, heat transfer efficiency is improved. This parameter change enables the system to operate effectively with reduced battery capability requirements.
3Device complexity
If direct heating of aerosol-forming material is used, then device structure is simplified, but heat transfer efficiency deteriorates
Solution Approach 1:
The thermally conductive member serves as an intermediary that enhances heat transfer from the heating element to the aerosol-forming material. Rather than complicating the device structure, this intermediary component is strategically positioned to maximize thermal contact and minimize energy losses, improving heat transfer efficiency without significant structural complexity.
