Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional heaters are used to generate aerosol from medium, then aerosol can be produced, but significant warm-up time is required before aerosol delivery
Solution Approach 1:
The aerosol generating medium is pre-loaded onto a movable substrate (such as a spool or tape) before use. This preliminary preparation allows the medium to be readily available for immediate aerosol generation without requiring extensive warm-up of the entire system, thereby reducing warm-up time while maintaining productivity
Solution Approach 2:
The aerosol generating medium is divided into separate portions or segments on the substrate, allowing individual sections to be heated and used sequentially. This segmentation enables faster aerosol delivery by focusing heating energy on specific segments rather than requiring the entire system to reach operational temperature, thus reducing overall warm-up time
2Adaptability or versatility
If device configuration is changed to use different aerosol generating media, then media variety is improved, but device modification or reloading is required
Solution Approach 1:
The device is designed with a universal substrate holder and heating mechanism that can accommodate multiple types of aerosol generating media loaded on different substrate formats. This multi-functional design allows the same device to work with various media without requiring structural modifications, thereby improving adaptability while maintaining device simplicity
Solution Approach 2:
The substrate carrying the aerosol generating medium is designed as a disposable component that can be easily replaced. Different substrates with different media can be loaded into the same device without modification, allowing users to change media types by simply replacing the substrate rather than modifying the device, thus improving versatility while minimizing device complexity
3Speed
If aerosol generating medium is moved along a line at an angle to the flow path, then rapid aerosol delivery is achieved, but heating zone positioning becomes more complex
Solution Approach 1:
The substrate is positioned and moved at an angle relative to the aerosol flow path, creating a geometric arrangement where the medium travels through the heating zone efficiently. This angular positioning optimizes the path length and heating efficiency while maintaining rapid aerosol delivery, balancing speed requirements with heating zone positioning complexity
