Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional aerosol-generating devices are used, then aerosol can be generated, but preheating time is required and device durability is reduced
Solution Approach 1:
The aerosol-generating article is divided into multiple segments with different functions: a first segment containing moisturizer for immediate aerosol generation, a medium segment with tobacco material, and a second segment with fragrance material. This segmentation allows different materials to be transferred at different temperatures, eliminating the need for preheating while extending device lifespan.
Solution Approach 2:
The invention utilizes temperature-dependent transfer characteristics of different materials. The moisturizer transfers at lower temperatures immediately, while tobacco and fragrance materials transfer at higher temperatures. This parameter-based differentiation enables aerosol generation without preheating and reduces thermal stress on the device, improving durability.
2Productivity
If high temperature heating is applied, then complete nicotine transfer occurs, but aerosol generation efficiency is reduced due to preheating requirements
Solution Approach 1:
The first segment containing moisturizer is designed to transfer immediately at lower temperatures before high-temperature heating begins. This preliminary action provides immediate aerosol generation, eliminating the need to wait for preheating while ensuring complete transfer of tobacco and fragrance materials follows afterward.
Solution Approach 2:
The moisturizer in the first segment acts as an intermediary that facilitates immediate aerosol generation at low temperatures. This intermediary enables users to start using the device immediately without preheating, while the subsequent high-temperature phase ensures complete transfer of active ingredients.
3Reliability
If low temperature operation is used, then device durability is improved, but aerosol transfer effectiveness is insufficient
Solution Approach 1:
The invention employs dynamic temperature control with multiple operating phases. Initially, low-temperature operation transfers the moisturizer for immediate aerosol generation and device durability. Subsequently, high-temperature operation transfers tobacco and fragrance materials completely. This dynamic approach optimizes both durability and effectiveness.
Solution Approach 2:
The aerosol generation process occurs in periodic stages: first, low-temperature transfer of moisturizer provides immediate aerosol; then, high-temperature transfer of tobacco and fragrance materials follows. This periodic action ensures device durability during initial use while achieving complete material transfer over time.
