Paint Roller Cover Cleaner with High-Pressure Jet
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 issues, as well as being messy and inconvenient.
Innovation Solution
A paint roller cover cleaner that uses a high-pressure pump to produce a fluid jet within an enclosure, allowing for efficient cleaning of the roller cover without the need for a pressurized water supply, with a nozzle and carriage system to rotate and clean the roller cover, and a waste fluid reservoir for containment and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressurised mains water source is used for cleaning roller covers, then cleaning effectiveness is improved, but water consumption increases to 20-300 litres per roller cover
Solution Approach 1:
The invention changes the pressure parameter of the water supply from typical mains pressure (well below 150 psi) to high pressure (200-4000 psi) using a dedicated high pressure pump. This parameter change enables effective cleaning with dramatically reduced water consumption (less than 4 litres per roller cover compared to 20-300 litres with mains water).
2Reliability
If high volume waste water is produced during cleaning, then cleaning effectiveness is improved, but waste water disposal and recycling becomes impractical and expensive
Solution Approach 1:
By changing the pressure parameter to high pressure (200-4000 psi), the system achieves effective cleaning with less than 4 litres of water per roller cover, transforming waste water from an unmanageable volume (20-300 litres) to a manageable volume that can be contained, transported, and recycled practically.
Solution Approach 2:
The invention enables recovery and recycling of waste water by reducing the volume to less than 4 litres per roller cover. The enclosed system contains the waste fluid, making it practical to collect, transport, and recycle, thereby recovering the water resource that would otherwise be lost.
3Device complexity
If mains water pressure is used for cleaning, then equipment simplicity is maintained, but cleaning performance becomes impractical in many cases
Solution Approach 1:
The invention introduces a high pressure pump to create a hydraulic system that delivers water at 200-4000 psi. This hydraulic approach replaces inadequate mains water pressure (well below 150 psi) while maintaining relative equipment simplicity through the use of a straightforward pump-nozzle-carriage mechanism.
4Device complexity
If manual cleaning operations are used, then device complexity is reduced, but cleaning performance and convenience deteriorate
Solution Approach 1:
The invention introduces dynamic elements including an automatically moving carriage that traverses the roller cover length and a roller cover rotation mechanism driven by the high pressure water jet. These dynamic features automate the cleaning process, improving convenience and performance while maintaining reasonable device complexity through simple mechanical designs.
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 solution enables quick, effective cleaning of paint roller covers using minimal water, reducing waste and allowing immediate reuse, as the high-pressure jet effectively removes paint residue, and the enclosed system ensures containment and practical recycling of cleaning fluids.
Implementation Method 1
a high pressure pump capable of producing a fluid supply at a pressure of between 200 to 4000 psi; a nozzle supplied with pressurised fluid from the pump positioned to direct a jet of fluid at the nap of the roller cover to rotate the roller cover and facilitate cleaning
Implementation Method 2
direct a jet of fluid at the nap of the roller cover to rotate the roller cover and facilitate cleaning

AI summary
A paint roller cover cleaner including an enclosure for a roller cover, a high pressure pump and a nozzle supplied with pressurised fluid which directs a jet of fluid at the nap of the roller cover to rotate the roller cover and facilitate cleaning. In one embodiment a carriage moves the nozzle along the length of the roller cover to effect cleaning along the length of the roller cover. In another embodiment a plurality of controllable nozzles are provided at intervals along the length of the roller cover. In another embodiment the nozzle includes an inner sleeve and an outer sleeve which relatively rotate to align apertures in the respective sleeves to produce jets sequentially along the nozzle.
