Aerosol Texture Dispenser with Drier Accelerant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol dispensing systems for texture materials lack effective formulations to produce an orange peel texture pattern, with existing materials either drying too quickly and being malodorous or taking too long to dry and not being odor-free.
Innovation Solution
A system comprising a tin-plated steel aerosol dispenser with a valve assembly and outlet assembly that alters the cross-sectional area of the outlet opening, using a texture material mixture of solvent carrier, latex binder, fillers, and drier accelerant, which is propelled by a bi-phase propellant to create a spray pattern that forms an orange peel texture pattern while promoting efficient drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If solvent-based texture material is used, then drying speed is improved, but odor and harmful factors increase
Solution Approach 1:
The patent modifies the chemical composition parameters of the texture material by incorporating specific drying agents (metal salts like zinc oxide, calcium oxide, or barium oxide) and controlling the ratio of water to organic solvents. This parameter adjustment enables the material to dry at speeds comparable to solvent-based materials while maintaining lower odor levels through controlled evaporation characteristics.
Solution Approach 2:
The invention creates a composite texture material formulation combining water, organic solvents (alcohols, esters, or ketones), latex binder, fillers, and drying agents. This composite structure leverages the evaporative properties of multiple components to achieve rapid drying while the water-based foundation reduces overall odor compared to purely solvent-based systems.
2Object-generated harmful factors
If water-based texture material is used, then odor is reduced, but drying time increases
Solution Approach 1:
The patent adjusts the water content parameter within specific ranges (60-95% by weight) and incorporates drying agents that catalyze evaporation. This parameter optimization allows the material to retain water-based odor benefits while achieving drying speeds through controlled moisture release and vapor pressure management.
Solution Approach 2:
The invention introduces organic solvents (alcohols, esters, or ketones) as intermediary substances that facilitate faster evaporation from the water-based matrix. These intermediaries have higher vapor pressures than water, accelerating the drying process while the predominant water content maintains low overall odor characteristics.
3Manufacturing precision
If outlet assembly cross-sectional area is reduced, then orange peel texture pattern is achieved, but spray coverage area decreases
Solution Approach 1:
The patent employs periodic or oscillating spray action through the valve assembly mechanism, creating multiple overlapping spray cycles. This periodic dispensing allows the use of smaller outlet openings to achieve precise orange peel patterns while compensating for reduced per-spray coverage through repeated applications that build up the desired texture over time.
Solution Approach 2:
The invention creates local quality variation in the spray output by using the restricted outlet opening to generate specific droplet size distributions and spray patterns. The smaller opening produces finer, more uniform droplets that create the characteristic orange peel texture locally, while the overall coverage is achieved through systematic application patterns.
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 efficiently dispenses a texture material that forms an orange peel pattern with a balanced drying time and minimal odor, suitable for small area coatings and repairs, using a combination of solvent and water-based components.
Implementation Method 1
The propellant material pressurizes the texture material within the container assembly. When the valve assembly is placed in its open configuration, the vapor portion of the bi-phase propellant material forces the texture material out of the container assembly along the dispensing path.
Implementation Method 2
When the valve assembly returns to its closed position, part of the liquid portion of the bi-phase propellant material changes to the vapor state because of the drop in pressure within the container assembly.
Implementation Method 3
The drier accelerant promotes drying of the dispensed texture material in the desired orange peel texture pattern.

AI summary
A system for dispensing texture material in an orange peel pattern has an aerosol dispenser and a contained material. The aerosol dispenser is a container assembly, a valve assembly, and an outlet assembly. The contained material is texture material and propellant material. The texture material comprises water as a solvent/carrer, latex binder, fillers, and drier accelerant. The outlet assembly alters the cross-sectional of the outlet opening to correspond to a desired orange peel texture pattern. The valve assembly allows the propellant material to force at least a portion of the texture material out of the outlet opening in a spray pattern corresponding to the desired orange peel texture pattern. The drier accelerant promotes drying of the dispensed texture material.
