Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette pot structures suffer from uneven heating of tobacco shreds due to point heating sources, leading to waste and inadequate air flow to carry away effective components, resulting in inefficient aroma release.
Innovation Solution
A pot structure with a cup-shaped heating device and a cage made of heat-conductive materials, featuring an air inlet channel and a heat conductive tube to ensure even heating and efficient smoke carrying, where the heating device is a surface heating source and the airflow passes through the tobacco fully.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a ring-shaped wall heating resistor is used as a point heating source, then the heating temperature can reach 400-650°C to release aroma from tobacco shreds, but the heating will be uneven causing some tobacco shreds to be baked too fully and wasted
Solution Approach 1:
The heating system is segmented into multiple heating resistors arranged in a grid pattern on the heating plate, rather than using a single ring-shaped heating element. This segmentation allows heat to be distributed across multiple zones, improving heating uniformity while maintaining the required temperature range for aroma release.
Solution Approach 2:
The heating approach transitions from a one-dimensional ring-shaped heater to a two-dimensional grid array of heating elements. This dimensional change enables more uniform heat distribution across the heating surface, addressing the uneven heating problem while maintaining effective temperature ranges.
2Device complexity
If air enters through the hole on the bottom of the pot and smoke discharges from the opening, then the structure is simple, but the airflow is not adequate to carry away the most effective components of the tobacco shreds
Solution Approach 1:
The airflow system is segmented into multiple air inlet holes distributed across the heating plate and multiple air outlet holes at the periphery. This segmentation creates multiple airflow pathways that enhance air circulation through the tobacco shreds, improving the carrying away of effective components while maintaining structural simplicity.
Solution Approach 2:
The heating plate serves as an intermediary structure that integrates both heating functions and airflow management. Air inlet holes are formed directly in the heating plate, creating an integrated design that simplifies the overall structure while improving airflow efficiency for aroma release.
