Paint Storage Tube with Preservative Wick
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Artists face challenges in preserving and storing oil and acrylic paints, as they tend to dry out or oxidize quickly, leading to waste and inconvenience when transferring paint daubs from palettes to storage containers, especially when working outdoors.
Innovation Solution
A preserving storage accessory featuring a tray that fits into a cylindrical container with end caps containing a preservative, such as a felted wool wick for oil paints or silica gel for acrylics, maintains a humid environment, preventing oxidation and evaporation, and allows for easy transport and storage of paint daubs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If paint is transferred from palette to storage container using a palette knife, then paint can be stored for later use, but paint is lost during the transfer process and the process is messy
Solution Approach 1:
The paint tray is nested inside the storage container, allowing the paint daubs to remain on the tray while being stored within the container. This eliminates the need to transfer paint from the tray to the container, preventing paint loss during transfer while maintaining storage capability for extended duration
Solution Approach 2:
The tray acts as an intermediary between the paint tubes and the storage container. Paint daubs are placed on the tray and then the entire tray is placed in the container, eliminating the need for direct transfer from tray to container and preventing paint loss
2Ease of operation
If paint is stored in an open container, then access to paint is easy, but paint dries out or oxidizes quickly
Solution Approach 1:
The container is designed with a tight-fitting lid that creates a sealed environment. This flexible closure mechanism prevents air exposure while maintaining easy access to paint, preventing oxidation and drying out without compromising accessibility
Solution Approach 2:
The sealed container creates a protected environment that isolates paint from atmospheric oxygen. This inert environment prevents oxidation of oil paints and drying out of acrylic paints, maintaining paint freshness while allowing easy access through the lid
3Duration of action of stationary object
If paint is stored in a freezer to preserve it, then paint can be stored for extended periods, but the process is inconvenient and requires temperature control
Solution Approach 1:
The preservative substance automatically prevents oxidation and drying out without requiring external intervention or temperature control. The system serves itself by using the chemical properties of the preservative to maintain paint freshness, eliminating the need for freezer storage and complex temperature control mechanisms
Solution Approach 2:
The patent replaces the mechanical freezer system with a chemical preservation system. Instead of using temperature control to prevent paint degradation, the invention uses chemical preservatives that naturally prevent oxidation and drying, simplifying the storage system while maintaining extended storage capability
4Reliability
If a preservative is placed in direct contact with paint, then preservation effect is maximized, but the preservative may contaminate or alter the paint
Solution Approach 1:
The tray serves as an intermediary barrier between the preservative and the paint. The preservative is placed in the container bottom or on a separate layer, while the tray with paint daubs is placed on top. This intermediary structure allows the preservative to protect the paint without direct contact, preventing contamination while maintaining preservation effectiveness
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
This system keeps paints fresh for weeks, reducing waste and the need for frequent refilling, allowing artists to resume painting sessions with the same colors, while keeping the workspace clean and efficient, and eliminating the need for freezer storage for oil paints.
Implementation Method 1
oil paint hardens through oxidation after a day or so outside the paint tube
Implementation Method 2
Eugenol, which is the volatile component of the clove oil, will slowly evaporate from the wick and keep the daubs of oil paints fresh for weeks at room temperature
Implementation Method 3
acrylic paints, which dry out instead of oxidizing, can be kept moist by adding water to silica gel pillows or sponges mounted inside the end caps

AI summary
This palette accessory and paint storage system keeps oil paint fresh and pliable for weeks at room temperature. A linear paint tray, upon which daubs of paint are placed, is stored inside an airtight tube. Felt wicks mounted inside the end caps hold clove oil, which prevents the oxidation of oil paints. For heavy bodied acrylics, the end caps are mounted with sponge material or silica gel that would be moistened to create a humid environment that prevents acrylics from drying and hardening. When the artist is ready to paint, the paint tray is removed from the storage tube and secured with clips or Velcro to a mixing palette, paint box, or easel. The painter dips into the paint daubs on the tray to mix the desired colors on their palette. When done painting, the paint tray, with the unused paint, is re-inserted into the tube for storage and transport.
