Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from oil leakage and a hot mouthpiece, leading to a poor user experience due to inadequate design and air tightness.
Innovation Solution
The electronic cigarette design incorporates a top cover with an oil injecting hole and aerosol outlet pipe, an atomizing assembly with an oil guiding port, and a light-emitting assembly to improve air tightness and user experience by preventing oil leakage and reducing mouthpiece temperature through heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional electronic cigarette atomizer is designed with an air inlet chamber, then air can be supplied for atomization, but oil leakage occurs from the air inlet chamber during use
Solution Approach 1:
The air inlet chamber is divided into two separate chambers: a first air inlet chamber that supplies air to the atomizing chamber, and a second air inlet chamber that supplies air to the aerosol outlet pipe. This segmentation prevents oil from leaking into the air supply path while maintaining adequate air supply for atomization.
Solution Approach 2:
A separating wall with a through-hole is introduced as an intermediary structure between the oil storing chamber and the air inlet chambers. The through-hole allows controlled air passage while the separating wall itself acts as a barrier that prevents oil from reaching the air inlet chambers, thus eliminating oil leakage.
2Temperature
If the aerosol outlet pipe is exposed to hot aerosol, then the atomization function is maintained, but the mouthpiece becomes hot during use
Solution Approach 1:
Cold air from the second air inlet chamber is introduced as a cooling intermediary that flows through the aerosol outlet pipe, absorbing heat from the hot aerosol and cooling the pipe before the aerosol reaches the mouthpiece, thus reducing mouthpiece temperature while maintaining atomization function.
Solution Approach 2:
The cooling air undergoes temperature change (a form of phase transition in thermal state) as it passes through the heated aerosol outlet pipe, absorbing heat and cooling down, thereby cooling the mouthpiece area without compromising the atomization process.
3Shape
If the electronic cigarette structure is simplified, then manufacturing cost is reduced, but aesthetic performance deteriorates
Solution Approach 1:
The first and second air inlet chambers are nested within the atomizer housing, with the separating wall integrated into the existing structure. The light-transmitting sleeve is also integrated into the housing, allowing multiple functional chambers to be nested within a single aesthetic外壳，improving appearance while avoiding excessive structural complexity.
