Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating devices for aerosolisable materials, such as tobacco, struggle to efficiently heat these materials without combustion, leading to incomplete vaporization and inconsistent aerosol production.
Innovation Solution
The apparatus employs a method of assembly that includes a first chassis with a heating arrangement and a first sleeve, where the chassis and sleeve engage via snap-fit arrangements to form a secure casing, ensuring proper heating and vaporization of aerosolisable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If combustion is used to heat aerosolisable material, then high temperature is achieved, but combustion occurs instead of controlled vaporization
Solution Approach 1:
The patent changes the temperature parameter from combustion levels (>500°C) to controlled vaporization levels (200-400°C), and modifies the heating rate parameter to achieve complete vaporization without combustion. This resolves the contradiction by finding optimal parameter values that enable high-temperature vaporization without reaching combustion conditions.
Solution Approach 2:
The patent employs periodic heating cycles with controlled duration and intensity, where the heating element is activated in specific time intervals to vaporize material completely before the next cycle begins. This periodic control prevents continuous heating that would lead to combustion, while still achieving sufficient temperature for vaporization during each cycle.
2Use of energy by moving object
If heating is insufficient, then energy consumption is reduced, but vaporization is incomplete and aerosol production is inconsistent
Solution Approach 1:
The patent ensures continuous heating action throughout the material residence time in the heating chamber, eliminating gaps in thermal processing. The heating element maintains consistent temperature application to ensure complete vaporization of all material particles, thereby achieving reliable and consistent aerosol production without excessive energy waste from repeated heating cycles.
Solution Approach 2:
The patent performs preliminary heating of the heating chamber and heating element before material is introduced, ensuring the thermal field is already at optimal temperature. This preliminary action reduces the total energy required during actual vaporization while guaranteeing consistent and complete vaporization from the start, improving both energy efficiency and aerosol production reliability.
3Manufacturing precision
If assembly complexity is increased to improve heating precision, then manufacturing cost increases
Solution Approach 1:
The patent divides the heating system into modular segments: a standardized heating element, a removable heating chamber, and a separate control module. This segmentation allows each component to be manufactured and tested independently with high precision, while the overall assembly remains simple through standardized interfaces and snap-fit connections, reducing both manufacturing cost and assembly complexity.
