Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol valves using compressed gas as a propellant face challenges with large spray particle sizes and inferior atomization due to the lack of liquid vaporization, leading to inefficient atomization effects.
Innovation Solution
An aerosol valve design featuring a gas intake structure, liquid intake structure, and flow guide structure that guides compressed gas and liquid into a vortex shape within the spray cavity, enhancing preliminary atomization before actuator use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If compressed gas is used as propellant to replace liquefied gas, then environmental harm is reduced (no ozone depletion, non-flammable), but atomization effect deteriorates (larger spray particle sizes, inferior atomization)
Solution Approach 1:
The valve body is divided into multiple functional regions: a compression chamber for gas storage, a mixing chamber for liquid-gas interaction, and a spray chamber for atomization. This segmentation allows compressed gas to be properly mixed with liquid to achieve fine atomization without requiring liquefied gas propellants, thus resolving the contradiction between environmental safety and atomization quality
Solution Approach 2:
A liquid reservoir and mixing mechanism are introduced as intermediaries between the compressed gas propellant and the final spray. The liquid in the reservoir is drawn into the mixing chamber where it combines with compressed gas, creating a two-phase flow that enables effective atomization while maintaining the use of environmentally friendly compressed gas propellants
2Device complexity
If traditional aerosol valve structure is used with compressed gas, then device simplicity is maintained, but spray particle size increases and atomization deteriorates
Solution Approach 1:
The patent combines multiple functions into an integrated valve assembly: the valve body houses both the compression chamber and mixing chamber, the valve stem controls both gas release and liquid dispensing, and the actuator integrates both sealing and spray delivery functions. This merging achieves fine atomization with compressed gas while maintaining overall structural simplicity and avoiding excessive complexity
Solution Approach 2:
The patent introduces a vertical dimension to the spray mechanism by incorporating a liquid reservoir positioned below the mixing chamber, with liquid rising through a capillary wick or pump mechanism. This dimensional arrangement allows compressed gas to effectively mix with and atomize liquid without significantly increasing horizontal complexity, resolving the contradiction between structure simplicity and atomization quality
