Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing paint roller squeegees are often designed for a fixed diameter, making them ineffective on roller covers of varying diameters, leading to incomplete paint removal, potential damage, and the need for excessive water or solvent use, which is wasteful and costly.

Innovation Solution

A squeegee tool with adjustable scraping blades that fit snugly around roller covers of different diameters, allowing for effective paint removal with minimal water or solvent use, using a pivot mechanism and optional diameter limiting system to accommodate various sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed diameter squeegee is used, then it can effectively clean roller covers of that specific diameter, but it cannot accommodate roller covers of varying diameters

Engineering Contradiction:

Improveadaptability to different roller cover diametersVSAvoidcomplexity of adjustable mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The squeegee employs a dynamic jaw mechanism where the first and second jaws can move relative to each other along the roller cover's circumference. This allows the opening between jaws to be adjusted to match different roller cover diameters, transforming a static fixed-diameter tool into a dynamic adaptable tool that maintains effective cleaning contact across varying sizes

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The squeegee is divided into separate functional components: a first jaw, a second jaw, and a mechanism allowing independent movement of each jaw. This segmentation enables the opening between jaws to be varied to accommodate different roller cover diameters while keeping the overall device relatively simple in construction

Inventive Principle:

Principle #1Segmentation

2Productivity

If excessive pressure is applied to remove all paint, then complete paint removal is achieved, but damage to the roller cover occurs

Engineering Contradiction:

Improvepaint removal completenessVSAvoiddamage to roller cover

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The squeegee applies pressure locally and uniformly through the first and second jaws that contact the roller cover surface. The pressure distribution is optimized at the jaw-roller interface, concentrating cleaning force exactly where needed while avoiding excessive pressure on any single point that could damage the roller cover material

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The squeegee design allows the user to apply force in the cleaning direction (parallel to roller axis) separately from the squeezing direction (perpendicular to roller axis). This self-service mechanism enables the tool to maintain consistent contact pressure while moving along the roller, achieving complete paint removal without requiring excessive squeezing force that could damage the cover

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple squeegees are purchased for different diameters, then each diameter can be cleaned effectively, but storage and cost increase

Engineering Contradiction:

Improvecoverage of different roller cover sizesVSAvoidnumber of squeegee tools

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The squeegee is designed as a universal tool that can clean roller covers of varying diameters through its adjustable jaw mechanism. By allowing the opening between jaws to be varied, a single squeegee performs the function of multiple fixed-diameter squeegees, eliminating the need to purchase and store multiple tools for different roller cover sizes

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If both hands are used to operate existing squeegees, then control is improved, but cleaning efficiency decreases

Engineering Contradiction:

Improvecontrol during cleaningVSAvoidcleaning efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The squeegee separates the control dimensions by allowing the user to apply force in the cleaning direction (parallel to roller axis) independently from the squeezing direction (perpendicular to roller axis). This dimensional separation enables one-handed operation where the thumb or finger applies cleaning force along the roller length while the jaw mechanism maintains contact pressure, improving both ease of operation and cleaning efficiency

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An adjustable paint roller cover squeegee tool is disclosed. The squeegee tool has two congruent members bolted using a common screw wherein the common screw is used for movement of the members similar to movement of a scissors. Each member has an elongated handle portion and a curved jaw portion, the jaw portions are configured to make a circular hole for a snug fit around a roller cover. In embodiments with an optional diameter limiting system, an adjustment screw can be laterally passed through one of the members along a continuous opening and can abut against a peg to limit the minimum diameter of the opening of the squeegee tool. In embodiments without an optional diameter limiting system, a use can simply squeeze the tool together around the roller cover using light pressure. The squeegee tool can be manually forced down the length of the roller cover to remove paint.
