Solution Overview

Problem

Conventional paint roller cleaning methods are inconvenient, time-consuming, and wasteful, often requiring separate cleaning apparatuses, handling paint-filled rollers, and excessive water or cleaning solution usage, which can lead to damaged rollers if not cleaned promptly and are not suited for quick reuse during painting processes.

Innovation Solution

A self-cleaning paint roller system that integrates a cleaning apparatus within the roller, allowing for quick and efficient cleaning of the roller sleeve without removal, using a nozzle to emit a fanned fluid spray that spins the roller sleeve, reducing cleaning time and water/cleaning solution consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate cleaning apparatus is used to clean the roller sleeve, then cleaning effectiveness is improved, but device complexity and storage requirements increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the cleaning apparatus with the paint roller by integrating a cleaning shield that attaches to the roller frame. The shield includes a fluid delivery system with nozzles positioned to spray cleaning solution directly onto the roller sleeve during rotation, merging two separate tools (paint roller and cleaner) into a single integrated device that performs both painting and cleaning functions

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated cleaning shield serves multiple functions: it shields the user from paint splatter during operation, delivers cleaning solution to the roller sleeve, and facilitates rapid cleaning without requiring separate cleaning equipment. This multi-functional design eliminates the need to transport and store separate cleaning apparatus

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the roller sleeve is removed from the roller for cleaning, then cleaning access is improved, but time consumption and mess increase

Engineering Contradiction:
Improvecleaning accessVSAvoidtime consumption
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The cleaning shield is pre-positioned and attached to the roller frame before cleaning is needed. The fluid delivery system is pre-configured with nozzles positioned to optimally spray the roller sleeve surface. When cleaning is required, the user simply activates the fluid delivery system while the roller rotates, eliminating the time-consuming steps of removing the sleeve and manually positioning cleaning equipment

Inventive Principle:
Principle #10Preliminary action

3Reliability

If conventional cleaning methods are used, then cleaning capability is achieved, but water and cleaning solution consumption increase

Engineering Contradiction:
Improvecleaning capabilityVSAvoidwater consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The cleaning shield concentrates cleaning resources precisely where needed by positioning nozzles to spray cleaning solution directly onto the roller sleeve surface during rotation. The shield structure contains and directs the fluid flow to contact only the necessary areas of the roller sleeve, preventing waste through overspray or unnecessary flooding of the entire roller assembly

Inventive Principle:
Principle #3Local quality

4Ease of manufacture

If the roller sleeve is not cleaned promptly, then paint removal is easier, but roller damage occurs and productivity decreases

Engineering Contradiction:
Improvepaint removal easeVSAvoidroller reuse capability
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The integrated cleaning system enables the roller to be cleaned immediately after use by the same user who used it, without requiring transport to a separate cleaning facility or assistance from another person. The quick-clean capability allows the roller to be serviced on-demand at the painting location, ensuring prompt cleaning that prevents paint drying and extends roller life

Inventive Principle:
Principle #25Self-service
