Atomizing Unit Cover Member Design for Aerosol Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing units for non-burning flavor inhalers face issues with excessive aerosol source supply, leading to potential leakage and heat loss during thermal atomization, which reduces atomization efficiency.
Innovation Solution
An atomizing unit design featuring a liquid holding member with a cover member that restricts aerosol source supply, ensuring proper contact with a heating element while minimizing heat loss by using a cover member with lower thermal conductivity, preventing oversupply and enhancing atomization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid holding member is disposed to contact the heating element, then atomization efficiency is improved, but aerosol source oversupply and leakage occur
Solution Approach 1:
The liquid holding member is designed with different functional zones: an inner side surface that contacts the heating element for efficient atomization, and an outer side surface that is covered by a cover member to prevent oversupply and leakage. This local differentiation of properties resolves the contradiction between achieving good contact for atomization and preventing excessive supply.
2Use of energy by moving object
If the liquid holding member contacts the heating element, then heat transfer is improved, but heat loss increases
Solution Approach 1:
The cover member is disposed to cover only the outer side surface of the liquid holding member, leaving the inner side surface exposed to contact the heating element. This ensures good heat transfer where needed while the cover member prevents heat loss to the surrounding environment, resolving the contradiction between heat transfer efficiency and heat loss prevention.
3Loss of energy
If the liquid holding member is covered by a cover member, then heat loss is reduced, but aerosol source supply is restricted
Solution Approach 1:
The cover member is strategically disposed to cover only the outer side surface of the liquid holding member in the orthogonal direction, while leaving the inner side surface uncovered to maintain contact with the heating element. This localized covering reduces heat loss without restricting aerosol source supply to the heating element, resolving the contradiction between heat loss reduction and aerosol supply maintenance.
