Rotatable Paint Roller Tray with Segmented Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paint roller trays are difficult to move and prone to spillage due to their weight and design, which can lead to paint being spilled during use, especially when filled with a large amount of paint.
Innovation Solution
A paint roller tray with a rotatable roll-off platform that can be positioned above the container, allowing for easy lifting and movement without tilting, featuring a handle for secure handling and a design that keeps the container horizontal, reducing spillage risks and enabling larger paint volumes without increased complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the container volume is increased to hold more paint, then the paint roller tray can contain larger paint volumes, but the weight increases making it difficult to move and increasing spillage risk
Solution Approach 1:
The paint roller tray is divided into two separate components: a stationary container for holding paint and a movable roll-off platform with handle. This segmentation allows the container to be large for holding substantial paint volumes while the platform remains lightweight and easy to maneuver for applying paint.
Solution Approach 2:
The handle and roll-off platform are extracted as a separate movable component from the container. The platform can be detached and repositioned, allowing the user to move only the lightweight platform with the roller while the heavy container remains stationary, thus improving ease of movement without sacrificing paint capacity.
2Ease of operation
If the painter grabs a corner of the paint roller tray to move it, then the tray can be moved, but the tray bends under paint weight and paint is spilled
Solution Approach 1:
By separating the container from the roll-off platform, the platform becomes a lightweight component that does not bear the full weight of the paint. The user moves only the platform with the roller, eliminating the bending and spilling issues that occur when moving the entire heavy container.
Solution Approach 2:
The handle is extracted as part of the roll-off platform rather than the container. This allows the user to grip and move only the lightweight platform component, preventing the tray from bending under paint weight while maintaining ease of movement.
3Productivity
If the painter dips the roller directly into the paint bucket and uses the roll off area, then paint application is possible, but many heavy lifts of the heavy paint bucket are required
Solution Approach 1:
The system is segmented into a stationary container that holds paint and a separate roll-off platform with handle. The user keeps the lightweight platform close while the container remains in one position, eliminating the need to repeatedly lift and move heavy paint buckets while maintaining efficient paint application.
Solution Approach 2:
The roll-off platform with handle is extracted as a separate component that can be positioned close to the work area. The user moves only this lightweight platform to apply paint, while the heavy container remains stationary, thus improving productivity without requiring heavy lifts.
4Productivity
If the paint roller tray is moved while the painter presses the paint roller against the roll off area, then painting can continue, but paint is spilled due to quick movements or tray bending
Solution Approach 1:
By separating the container from the roll-off platform, the platform becomes a lightweight component that can be moved freely without carrying heavy paint weight. The user can move the platform to continue painting without risking spillage from bending or quick movements, maintaining productivity while preventing spills.
Solution Approach 2:
The roll-off platform is extracted as a separate movable component that does not bear the full weight of the paint container. This allows the user to move the platform freely during painting without the risk of bending and spilling that occurs when moving the entire heavy tray assembly.
