Solution Overview
Problem
Existing aerosol generating devices generate a large amount of aerosol at the beginning of use but less towards the end, leading to decreased user satisfaction due to uneven heating of the aerosol generating article.
Innovation Solution
The device controls the heating area and power supply to the aerosol generating article over time by using deformable heaters and thermal switches to adjust the heating zones dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the heater quickly transfers heat to the entire area of the medium, then a large amount of aerosol is generated at the beginning, but relatively less aerosol is generated at the end, decreasing user satisfaction
Solution Approach 1:
The heater is designed with a deformable portion that changes its shape and heating area dynamically in response to temperature changes. The heater transitions from a state with larger heating area at lower temperatures to a state with smaller heating area at higher temperatures, creating a dynamic heating pattern that ensures uniform aerosol generation throughout the heating process
Solution Approach 2:
The deformable portion of the heater utilizes thermal expansion principles to change its configuration based on temperature. As the heater temperature increases, the deformable portion expands or contracts in a controlled manner, adjusting the effective heating area to prevent rapid heat transfer to the entire medium and ensuring consistent aerosol generation
2Productivity
If the entire area of the medium is heated at the same time, then a large amount of aerosol is generated in a short period, but the heating is uneven and causes decreased user satisfaction
Solution Approach 1:
The heater employs a deformable portion that dynamically adjusts its heating area based on real-time temperature feedback. The heater transitions between different configurations, initially heating a larger area and then transitioning to heat a smaller area, creating a progressive heating pattern that ensures uniform temperature distribution throughout the medium
Solution Approach 2:
The heating process incorporates periodic transitions of the deformable portion, alternating between expanding and contracting states. This periodic action creates cycles of heat transfer that prevent localized overheating and ensure uniform heating across the entire medium, resulting in consistent aerosol generation
