Solution Overview
Problem
Current heat not burn products face issues with uneven baking, small smoke emission, light taste, and poor user experience due to inefficient heating methods that lead to temperature inconsistencies and contamination from metal ions or pollutants.
Innovation Solution
A ceramic heating element with a honeycomb porous structure and an alumina honeycomb ceramic body, featuring a large heating surface area and high thermal conductivity, is used to heat air, which is then evenly distributed to bake the smoking product, reducing temperature differences and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional heating methods are used in heat not burn products, then the heating process is simple, but the temperature distribution is uneven and the heating efficiency is low
Solution Approach 1:
The patent employs a porous ceramic heating body with a three-dimensional porous structure that allows air to penetrate uniformly throughout the material. The porous structure increases the effective heating surface area and enables even heat distribution while maintaining high heating efficiency through improved air-flow heating.
2Power
If metal heating elements are used, then the heating effect is strong, but metal ions contaminate the smoking product causing odd smells
Solution Approach 1:
The patent uses a composite structure combining ceramic material for the heating body with a heating wire embedded within. The ceramic material serves as a contamination-free heating element that can be heated to high temperatures without releasing harmful ions, while still achieving the required heating effect.
3Productivity
If direct contact heating is used, then the heating efficiency is high, but the heating element gets contaminated by pollutants from the smoking product
Solution Approach 1:
The patent introduces air as an intermediary medium for heat transfer. The heating body heats the air, and the hot air then contacts the smoking product, eliminating direct contact between the heating element and pollutants. This indirect heating method maintains high heating efficiency while preventing contamination of the heating element.
4Productivity
If the heating surface area is increased, then the heating efficiency improves, but the device complexity increases
Solution Approach 1:
The patent transitions from a two-dimensional surface heating approach to a three-dimensional volumetric heating structure. The porous ceramic body provides heating throughout its volume rather than just at the surface, effectively increasing the heating surface area without proportionally increasing device complexity.
