Solution Overview
Problem
Conventional electronic cigarette products using wick-coil technology face issues with local overheating due to liquid supply shortages, leading to 'dry puff' and potential pollutant release, which needs to be addressed for reliable and safe operation.
Innovation Solution
The evaporator insert features a carrier that mechanically stabilizes the evaporator, with a through-opening for liquid supply and an air duct design to promote efficient vaporization, including electrical contacts and sensors for control and monitoring, ensuring reliable and reproducible vaporization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wick-coil technology is used for liquid supply to the evaporator, then the device structure is simple, but insufficient wicking leads to localized overheating and dry puff
Solution Approach 1:
The patent extracts the wick component from the system and replaces it with a direct liquid supply mechanism where liquid is delivered directly to the evaporator surface without capillary action, eliminating the wicking limitation that causes localized overheating
Solution Approach 2:
The patent introduces a liquid distribution layer as an intermediary between the liquid supply and evaporator, ensuring uniform liquid distribution across the evaporator surface and preventing localized overheating through controlled liquid flow
2Device complexity
If the evaporator is integrated directly into the base part, then the structure is compact, but assembly and disassembly become difficult
Solution Approach 1:
The patent segments the device into modular components: a base part, an evaporator assembly, and a housing. The evaporator is mounted on a support structure that can be independently assembled and disassembled, facilitating manufacturing and maintenance while maintaining structural integration during operation
3Volume of stationary object
If the evaporator outlet side is not aligned parallel to the longitudinal axis, then space utilization may be improved, but effective arrangement and vapor addition to airflow are reduced
Solution Approach 1:
The patent aligns the evaporator outlet side parallel to the longitudinal axis of the device, optimizing the spatial arrangement for efficient vapor release into the airflow channel. This dimensional alignment ensures that vapor is effectively added to the airflow in the direction of flow, maximizing vaporization efficiency
