Paint Roller Cover Cleaner With Fan Jet Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint roller cover cleaning methods are inefficient, wasteful of water, and often require a pressurized mains water supply, which is not always available, leading to excessive water usage and disposal challenges, as well as ineffective cleaning due to low pressure.
Innovation Solution
A paint roller cover cleaner system that uses a high-pressure jet within an enclosure to clean the roller cover, with a nozzle configured to produce a fan-shaped jet that rotates the roller cover, allowing for efficient cleaning with minimal water usage, and includes a clamp to secure the handle and a waste fluid reservoir for containment and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mains water supply is used for cleaning roller covers, then water is readily available, but water pressure is insufficient (below 150 psi) resulting in ineffective cleaning
Solution Approach 1:
The patent replaces the mechanical water pressure system with a portable high-pressure pump system that can generate sufficient pressure (above 150 psi) independently of mains water supply, thereby maintaining cleaning effectiveness without relying on inadequate external pressure sources
Solution Approach 2:
The patent changes the pressure parameter from low-pressure mains water (below 150 psi) to high-pressure pump output (above 150 psi), enabling effective cleaning while maintaining ease of operation through portable equipment
2Reliability
If high volume water is used to clean roller covers, then cleaning effectiveness is improved, but water waste and disposal costs increase substantially
Solution Approach 1:
The patent implements a self-contained system with integrated waste water containment and recycling capabilities, allowing the cleaning system to manage its own fluid resources efficiently without external disposal infrastructure, thereby reducing water waste while maintaining cleaning effectiveness
Solution Approach 2:
The patent recycles waste water through coagulation and filtration systems, recovering clean water for reuse and minimizing water loss, thereby maintaining effective cleaning while substantially reducing water consumption and disposal requirements
3Adaptability or versatility
If portable high-pressure pump and containment system are used, then water usage is reduced and no mains supply is needed, but device complexity increases
Solution Approach 1:
The patent merges multiple functions (high-pressure pumping, waste water containment, coagulation, filtration, and recycling) into a single integrated portable unit, thereby achieving adaptability and independence while managing device complexity through functional consolidation
4Reliability
If large volume waste water is produced, then cleaning effectiveness is achieved, but containment and transportation becomes impractical
Solution Approach 1:
The patent recycles waste water through coagulation and filtration, converting waste volume into reusable water, thereby maintaining cleaning effectiveness while dramatically reducing the volume of waste water that requires containment and transportation
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 effectively cleans paint roller covers using a small volume of water, leaving them almost dry and ready for immediate reuse, reducing waste and the need for external water supplies, while allowing for efficient recycling and transportation of cleaning fluids.
Implementation Method 1
one or more nozzles supplied with high pressure fluid from a high pressure pump, each nozzle configured to produce a jet of fluid directed at the nap of the roller cover to rotate the roller cover and facilitate cleaning

AI summary
A paint roller cover cleaner for cleaning a paint roller cover. The paint roller cover cleaner has one or more nozzles that spray the cover and that may each produce a fan-shaped jet in a plane that is at an angle to the longitudinal axis of the roller cover. The paint roller cover cleaner may also have a clamp for clamping a handle of the paint roller, another nozzle for cleaning an enclosure of the paint roller cover cleaner, a lid for the enclosure that drips within the mouth of the enclosure and does not move laterally across the roller cover to open. A system including a paint roller cover cleaner and a fluid supply that can contain the paint roller cover cleaner is also provided.
