Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices suffer from condensate leakage through ventilation holes and long airflow channels, leading to user discomfort and reduced smoke generation, especially when the battery swells due to improper use.
Innovation Solution
The ventilation hole of the atomizing base is positioned outside the air passage, surrounded by a fence, and the airflow switch is installed on the upper end of the battery holder with an air intake hole, creating a shorter air intake channel that bypasses the battery assembly, ensuring smooth inhalation and preventing condensate leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a coil heater is used to heat the atomizing liquid, then the liquid can be heated to atomization temperature, but the liquid may be overheated causing decomposition and carbonization
Solution Approach 1:
A heat insulating member is introduced as an intermediary between the coil heater and the atomizing liquid. This mediator controls heat transfer to prevent overheating while ensuring sufficient heating for atomization, thereby avoiding liquid decomposition and carbonization.
Solution Approach 2:
The heat insulating member is pre-positioned between the heater and liquid to cushion against excessive heat transfer before it can cause decomposition. This preventive measure ensures the liquid reaches atomization temperature without exceeding the decomposition threshold.
2Productivity
If the heater surface area is increased to improve heating efficiency, then more liquid can be vaporized, but the device size and power consumption increase
Solution Approach 1:
The invention changes the thermal parameters by introducing a heat insulating member with specific thermal conductivity properties. This allows optimized heat transfer control, achieving high vaporization rates without requiring excessive heater surface area or power consumption.
3Reliability
If the heater surface area is increased to ensure sufficient heat supply, then atomization can be maintained, but the apparatus becomes larger and more complex
Solution Approach 1:
The heat insulating member serves as a mediator that simplifies the heater structure while ensuring reliable atomization. It provides controlled heat transfer, eliminating the need for complex high-surface-area heater designs.
4Loss of energy
If heat insulation is improved to prevent heat loss, then energy efficiency increases, but the device structure becomes more complex
Solution Approach 1:
The heat insulating member is merged with the existing heater or atomizer structure, combining insulation functionality with the existing design. This reduces overall structural complexity while effectively preventing heat loss and improving energy efficiency.
