Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-cigarettes face issues with poor e-liquid supply and a smeared core due to difficulties in balancing internal and external pressure differences, leading to user experience degradation and potential device damage.
Innovation Solution
Incorporating a ventilation channel on the upper cover of the e-cigarette atomization device to establish communication between the liquid storage chamber and the atomization chamber, allowing for airflow balance and continuous e-liquid flow to the atomization assembly for heating and vapor generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If gas circulation is used to restore pressure balance in the liquid storage chamber, then pressure balance can be achieved, but e-liquid supply becomes poor and the core becomes smeared
Solution Approach 1:
The patent divides the pressure balance restoration function into two separate pathways: a first venting channel for gas circulation to restore pressure balance, and a second venting channel for e-liquid supply. This segmentation allows gas and e-liquid to flow through different channels, preventing the core from becoming smeared while maintaining pressure balance.
Solution Approach 2:
The patent introduces a venting channel structure as an intermediary component that mediates between the liquid storage chamber and the external environment. This intermediary structure enables controlled gas circulation for pressure balance while preventing direct e-liquid leakage that would cause core smearing.
2Stress or pressure
If the liquid storage chamber is sealed to maintain pressure, then pressure stability is improved, but e-liquid cannot flow continuously to the atomization assembly
Solution Approach 1:
The patent implements a dynamic venting channel structure that can open and close based on pressure conditions. The channel includes a closing member that responds to pressure changes, allowing the system to automatically adjust between sealed and open states to maintain pressure stability while enabling continuous e-liquid flow when needed.
Solution Approach 2:
The patent changes the state parameter of the venting channel from fixed to variable. The channel can transition between open and closed states based on pressure differential, allowing the system to optimize both pressure stability and e-liquid flow continuity by adjusting the venting channel's openness parameter dynamically.
3Productivity
If the venting channel is opened to allow e-liquid flow, then e-liquid supply improves, but pressure balance is disrupted and core smearing occurs
Solution Approach 1:
The patent segments the venting function into distinct channels: one dedicated to gas circulation for pressure balance and another for e-liquid supply. This segmentation ensures that when the e-liquid supply channel is open, the pressure balance channel remains functional, preventing core smearing while maintaining adequate e-liquid flow.
Solution Approach 2:
The patent extracts the e-liquid supply function from the general venting channel and creates a separate dedicated pathway. This extraction allows e-liquid to flow through its own channel without interfering with the pressure balance mechanism, resolving the conflict between e-liquid supply and pressure stability.
