Engineering Contradiction Analysis
1Object-affected harmful factors
If electrical energy is used to vaporize volatile materials instead of combusting tobacco, then harmful combustion by-products are reduced, but the device complexity increases due to the need for pumps and control components
Solution Approach 1:
The patent replaces the mechanical combustion process with an electrical vaporization system. Instead of burning tobacco mechanically, electrical energy is applied to vaporize volatile materials, eliminating combustion by-products while introducing electrical components and control systems that manage the vaporization process
Solution Approach 2:
The patent employs pneumatic principles by using a pump to deliver pressurized gas through a porous medium. This pneumatic system facilitates the vaporization and delivery of aerosolized substances without requiring combustion, using fluid dynamics to control the aerosol generation and delivery process
2Productivity
If pumps and control components are added to deliver aerosolized substances, then the functionality and delivery efficiency are enhanced, but the device complexity increases
Solution Approach 1:
The patent segments the aerosol delivery system into distinct functional components: a pump for delivering gas, a porous medium for vaporization, and control components for managing the process. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and enabling independent optimization of delivery parameters
3Reliability
If a porous medium is used for vaporization, then the aerosolization process is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes porous materials as the core vaporization medium. The porous structure provides a large surface area for vaporization while maintaining mechanical stability. The controlled porosity allows for consistent aerosol generation, and the material's inherent properties reduce the need for complex manufacturing processes compared to precision-machined alternatives
