Aerosol Dispensing System with Dual Flow Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol texturing systems for DIY users lack the precision and control to match a variety of preexisting texture patterns, often requiring crude methods to adjust texture patterns, which are not highly repeatable and can lead to inefficiencies and waste of propellant.
Innovation Solution
An aerosol dispensing system with a container, conduit, valve system, and adjustable components that allow for precise control of the flow and outlet size, enabling users to match preexisting texture patterns by altering the cross-sectional area of the conduit passageway at multiple locations, thereby adjusting the texture pattern of the dispensed material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If commercial texture sprayers are used to achieve precise control of texture pattern, then manufacturing precision and adaptability are improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the single adjustment mechanism into two separate adjustment systems: a first adjustment system that controls propellant flow rate and a second adjustment system that controls outlet opening size. This segmentation allows independent control of each parameter, achieving precise texture pattern matching without the complexity of a fully integrated commercial sprayer system.
2Ease of operation
If aerosol systems are used for DIY texturing, then ease of operation and portability are improved, but manufacturing precision and adaptability deteriorate
Solution Approach 1:
The patent introduces two dynamic adjustment mechanisms that allow users to modify the spray characteristics in real-time. The first adjustment system dynamically controls propellant flow rate, while the second adjustment system dynamically changes outlet opening size, enabling the same aerosol device to produce multiple texture patterns adaptively.
Solution Approach 2:
The patent changes two key parameters independently: propellant flow rate (via the first adjustment system) and outlet opening size (via the second adjustment system). By allowing simultaneous variation of these parameters, the system can precisely match different texture patterns while maintaining ease of operation for DIY users.
3Adaptability or versatility
If propellant pressure is reduced to change texture pattern, then adaptability is improved, but loss of substance increases due to propellant drainage
Solution Approach 1:
Instead of solely relying on pressure reduction to change texture patterns, the patent introduces a second parameter control mechanism (outlet opening size adjustment) that works independently of propellant pressure. This allows texture pattern variation without necessarily draining propellant, as the outlet opening can be adjusted to achieve different patterns while maintaining efficient propellant usage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for more precise and repeatable texture pattern matching, reducing propellant waste and improving user control, making it comparable to commercial texture sprayers in terms of performance.
Implementation Method 1
The container contains the texture material and propellant under pressure. The valve is mounted to the container selectively to allow the pressurized propellant to force the texture material out of the container.
Implementation Method 2
The first adjustment system is arranged between the conduit inlet and the conduit outlet and alters a cross-sectional area of the conduit passageway to control flow of stored material
Implementation Method 3
The second adjustment system is arranged between the first adjustment system and the conduit outlet and alters a cross-sectional area of the conduit passageway to control flow of stored material
Implementation Method 4
The propellant material in the liquid phase is mixed with the texture material, and the texture material in the gas state pressurizes the mixture of texture material and liquid propellant material.

AI summary
An aerosol dispensing system for dispensing stored material in a spray comprises a container, a conduit, a valve system, a first adjustment system, and a second adjustment system. The container defines a chamber containing the stored material and pressurized material. The conduit defines a conduit passageway having a conduit inlet and a conduit outlet. The conduit inlet is arranged within the chamber, and the conduit outlet is arranged outside of the chamber. The valve system is arranged to allow and prevent flow of stored material along the conduit passageway. The first adjustment system is arranged to control flow of stored material along the conduit passageway. The first adjustment system is arranged between the conduit inlet and the conduit outlet. The second adjustment system is arranged to control flow of stored material along the conduit passageway. The second adjustment system is arranged between the first adjustment system and the conduit outlet.
