Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional heating devices are used to generate aerosol, then aerosol can be produced, but long warm-up times are required before the user receives the aerosolized payload
Solution Approach 1:
The substrate is divided into multiple discrete doses of aerosol generating medium arranged in a grid pattern. Each dose can be independently heated and consumed, allowing the device to rapidly deliver pre-measured portions without requiring prolonged heating of a large continuous medium. This segmentation enables quick transition between doses, reducing overall warm-up time.
Solution Approach 2:
The aerosol generating medium is pre-loaded onto the substrate in ready-to-use doses before the device is activated. This preliminary preparation allows the heating element to immediately process individual doses without requiring extensive warm-up time to prepare the medium, as each dose is already positioned and ready for rapid aerosolization.
2Adaptability or versatility
If current aerosol provision devices are used, then various aerosol generating media can be offered, but frequent device changes are required to enable change in the aerosol generating medium
Solution Approach 1:
The substrate design with its grid arrangement of doses can accommodate multiple types of aerosol generating media. The universal substrate structure allows different media formulations to be applied to the same substrate type, enabling media variety without requiring specialized device components for each medium type. This reduces the need for frequent device changes while maintaining adaptability.
Solution Approach 2:
Multiple doses of different aerosol generating media can be nested within the grid structure of a single substrate. This allows a variety of media to be integrated into one substrate unit, providing media diversity without requiring multiple separate devices or frequent device changes. The nested arrangement enables efficient use of space and simplifies the overall system.
3Temperature
If significant levels of heating are applied to generate aerosol from suitable media, then aerosol can be formed, but extended heating duration is required
Solution Approach 1:
The heating element is configured to apply heat locally to individual doses on the substrate rather than heating a large volume of medium uniformly. This localized heating approach concentrates thermal energy on small, specific areas, achieving the necessary temperature for aerosol generation in a shorter time frame compared to heating entire batches of medium. The local quality principle enables rapid temperature attainment with reduced overall heating duration.
Solution Approach 2:
The device applies excessive or intensified heating to small, partial portions (individual doses) rather than moderate heating to the entire medium supply. This partial excessive action on localized doses achieves rapid aerosolization by concentrating thermal energy, thereby reducing the total heating duration required while maintaining effective aerosol generation.
