Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning paint rollers are time-consuming and messy, requiring manual effort and preventing efficient cleanup of other supplies when multiple rollers need to be cleaned.
Innovation Solution
A paint roller cleaning system comprising an elongated cylindrical member with end-caps for attaching a water supply, directing water through the roller to effectively wash away paint residue, allowing for quick and efficient cleaning of roller covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning method is used, then cleaning can be performed with simple tools, but cleaning time is excessive and productivity is low
Solution Approach 1:
The patent applies hydraulic principles by using pressurized water flow through the elongated cylindrical member to clean the roller cover. The water pressure forces paint residue off the roller surface, enabling rapid cleaning without manual effort and reducing cleaning time from minutes to seconds.
Solution Approach 2:
The cleaning system segments the cleaning function into a dedicated device with specific components (elongated cylindrical member, end caps, positioning member) that can be quickly assembled and disassembled. This segmentation allows for rapid cleaning cycles and efficient handling of multiple rollers.
2Productivity
If pressurized water system is used, then cleaning speed is improved, but device complexity increases
Solution Approach 1:
The elongated cylindrical member serves multiple functions: it contains the pressurized water flow path, provides structural support, and works with the positioning member to secure the roller. This multi-functionality reduces the number of separate components needed, simplifying the overall device despite using pressurized water.
Solution Approach 2:
The positioning member is nested within the elongated cylindrical member, and the roller is inserted into the cylindrical member. This nested arrangement compactly organizes components, reducing device complexity while maintaining the pressurized water cleaning function.
3Productivity
If roller is held firmly for cleaning, then cleaning effectiveness is improved, but positioning accuracy is difficult to achieve
Solution Approach 1:
The positioning member automatically positions the roller correctly when inserted into the elongated cylindrical member. The roller itself facilitates its own proper positioning through the interaction with the positioning member, eliminating the need for complex external positioning mechanisms and ensuring consistent alignment for effective cleaning.
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 enables rapid cleaning of 18-inch paint roller covers in under a minute, saving time and energy by using pressurized water to remove paint without manual squeezing, and can be adapted for other sizes.
Implementation Method 1
water under pressure from the water outlet member (10) is directed so as to strike the roller cover (18) such that the roller cover (18) rotates thereby cleaning the paint roller

AI summary
A paint roller cleaning system including an elongated cylindrical member configured to receive a paint roller, a first-end-cap, and a second-end-cap. The first-end-cap for attachment at a first-end of the elongated cylindrical member and the second-end-cap for attachment at a second-end of the elongated cylindrical member. The first-end-cap includes a threaded-member and may couple to a water supply and direct water through a receiving-aperture. The second-end-cap includes an exit-aperture and a positioning-member for positioning the paint roller above the exit-aperture allowing for water to drain therethrough. The paint roller cleaning system may be used for cleaning a paint roller when inserted into the elongated cylindrical member and the water supply is activated.
