Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices face challenges in effectively heating aerosol generating materials without burning them, requiring a heater component design that efficiently transfers heat while maintaining control over the temperature and volume of the aerosol produced.
Innovation Solution
A heater component with a specific length-to-aerosol generating material length ratio between 1.03 and 1.25, combined with a coil for heating, ensures efficient heat transfer and temperature control, using materials like carbon steel or alloys with high iron content for effective heating, and a thin wall thickness for rapid heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heater component length is increased to ensure complete heating of aerosol generating material, then heating effectiveness is improved, but device complexity and manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by establishing a specific length ratio range (1.03-1.25) between the heater component and aerosol generating material. This quantitative parameter optimization ensures the heater is long enough to completely heat the material while preventing excessive length that would complicate manufacturing. The defined ratio range provides clear manufacturing guidance while guaranteeing heating effectiveness.
2Speed
If the wall thickness of the heater component is reduced for rapid heating, then heating speed is improved, but structural strength decreases
Solution Approach 1:
The patent applies parameter changes by optimizing the wall thickness parameter of the heater component. By controlling the thickness within an appropriate range, the design achieves rapid heat transfer to the aerosol generating material while maintaining sufficient structural strength to withstand operational stresses and handle assembly requirements.
3Reliability
If the heater component extends significantly beyond the aerosol generating material, then heating completeness is improved, but heat loss and energy inefficiency increase
Solution Approach 1:
The patent applies parameter changes by defining an optimal length ratio (1.03-1.25) that balances heating completeness with energy efficiency. This specific ratio ensures the heater component extends just enough to completely heat the aerosol generating material while minimizing excessive extension that would cause unnecessary heat loss and reduce energy efficiency.
