Odor-Reducing Latex Paint with Embedded Adsorbents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Latex paints often emit unpleasant odors due to their components, and existing methods for odor reduction are temporary, require maintenance, and may have harmful side effects, necessitating a continuous, passive, and unobtrusive solution.
Innovation Solution
Incorporating odor-absorbing or adsorbing materials like zeolites, cyclodextrins, and activated carbon into latex paint compositions, along with optional odor-neutralizing agents and fragrance compounds, to reduce or neutralize odors both during application and after drying, while also providing long-term odor control in interior environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional latex paint is used, then the paint provides protective or decorative coating, but the paint emits unpleasant odors from its components
Solution Approach 1:
The patent introduces odor-absorbing materials (activated carbon, zeolites, cyclodextrins) as intermediary substances within the paint composition. These materials act as mediators that absorb or adsorb odor molecules generated by paint components, buffers, solvents, and other additives, thereby reducing unpleasant odors while maintaining the paint's protective and decorative functions
Solution Approach 2:
The patent creates a composite paint material by combining traditional latex paint components with odor-absorbing materials. This composite formulation integrates the functional properties of paint binders, pigments, and solvents with the odor-trapping capabilities of activated carbon, zeolites, or cyclodextrins, achieving both coating performance and odor reduction
2Object-generated harmful factors
If odor-reducing agents are used, then unpleasant odors are reduced, but the solution is temporary and requires monitoring or maintenance
Solution Approach 1:
The patent incorporates odor-absorbing materials directly into the paint composition before application. This preliminary action ensures that odor control capability is built into the paint itself, so when the paint is applied to the surface, the odor-absorbing materials are already in position to capture odor molecules, providing continuous long-term odor control without requiring subsequent maintenance or additional agents
Solution Approach 2:
The paint composition contains self-contained odor-absorbing materials that automatically perform odor reduction without external intervention. The activated carbon, zeolites, or cyclodextrins embedded in the paint continuously absorb odor molecules from the environment, providing autonomous, long-duration odor control that does not require monitoring, maintenance, or replacement
3Object-generated harmful factors
If conventional odor removal methods are used, then odors are temporarily reduced, but harmful or dangerous side effects occur
Solution Approach 1:
The patent converts potentially harmful conventional odor removal methods into beneficial passive absorption. Instead of using chemical agents or electrical devices that may produce harmful byproducts, the patent employs physically adsorbing materials (activated carbon, zeolites, cyclodextrins) that safely trap odor molecules through physical adsorption, eliminating harmful side effects while maintaining effective odor reduction
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 paint composition effectively reduces odors in the air by trapping or neutralizing odor particles, providing a continuous and pleasant scent, and preventing mold or mildew growth, thus addressing the issue of persistent odors in interior spaces.
Implementation Method 1
These materials are typically porous, such that an odor particle may associate with pores in the odor absorbing material to become trapped within the pore, thus removing the odor from the air
Implementation Method 2
Odor adsorbing materials include activated carbon, sodium bicarbonate, and cyclodextrins. Odor particles chemically or physically associate with the surface of the odor adsorbing materials
