Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol generating systems, such as e-cigarettes, often experience misconnections or misalignments between the heating element and the vaporizable material cartridge, leading to leakage of vaporizable material and inefficient heating.
Innovation Solution
The system employs a conically shaped heating element and a corresponding conically shaped alignment element in the cartridge, ensuring automatic alignment and adjustment, thereby preventing leakage and ensuring efficient heating and aerosol generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional heating element and cartridge connection is used, then the device structure is simple, but misconnections or misalignments occur leading to leakage of vaporizable material
Solution Approach 1:
The heating element employs a conical shape with a sloped surface that complements the conical cavity in the cartridge. This curved geometric design enables automatic self-alignment when the cartridge is inserted, ensuring proper contact between the heating element and the vaporizable material while preventing misconnection and leakage.
2Productivity
If a conventional heating element is used, then the manufacturing process is simple, but inefficient heating occurs due to improper contacting
Solution Approach 1:
The conical geometry with a sloped surface allows the heating element to make optimal contact with the vaporizable material throughout the cartridge cavity. This curved design ensures efficient heat transfer across the entire contact surface, improving heating efficiency while maintaining manufacturability through conventional forming processes.
3Reliability
If a conventional heating element is used, then the device structure is simple, but leakage of vaporizable material occurs from the capsule
Solution Approach 1:
The conical heating element with its sloped surface fits precisely into the conical cavity of the cartridge, creating a self-sealing interface. This curved geometric配合 ensures that the capsule is properly contained and sealed during insertion, preventing leakage of vaporizable material while maintaining a relatively simple overall device structure.
