Solution Overview

Problem

Existing paint roller systems with moving parts are laborious to use due to paint lodging in frame components, leading to uneven application and increased user effort, and are prone to frame instability or breakage from continuous flexing.

Innovation Solution

A paint roller system with a frame devoid of moving parts, featuring parallel frame arms with end pieces that prevent paint from entering the roller and incorporate a snap connection mechanism for easy assembly and disassembly, allowing for free rotation and even paint distribution with minimal user effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a frame with moving parts is used to allow paint roller engagement and disengagement, then the paint roller can be removed and replaced, but paint lodges in the connection elements and moving parts causing difficult rolling motion and uneven paint application

Engineering Contradiction:
Improvepaint roller removabilityVSAvoidrolling motion consistency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The invention removes all moving parts and connection mechanisms from the frame structure. Instead of using joints, hinges, or flexible connections that can accumulate paint, the frame is constructed as a rigid, continuous structure with integrated roller engagement features that eliminate crevices where paint could lodge.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than designing a frame that flexes or moves to accommodate the roller, the invention inverts the approach by making the frame completely rigid and stationary, and instead providing mechanisms for the roller to be securely held in place without requiring any movement of the frame structure.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If frame arms are flexed continuously to engage and disengage paint rollers, then the paint roller can be mounted and removed, but the frame arms stretch resulting in unstable mounting or breakage

Engineering Contradiction:
Improveroller assembly easeVSAvoidframe arm integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The invention divides the roller engagement function into separate, non-flexing components. Instead of requiring the entire frame arm to flex, the engagement mechanism is segmented into fixed frame elements with specific engagement features that interface with corresponding features on the roller, eliminating the need for continuous flexing of structural components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame is pre-configured with engagement features during manufacturing that allow for easy roller attachment without requiring the user to flex or deform the frame arms. The engagement mechanism is prepared in advance with appropriate geometry and clearance to facilitate simple assembly and disassembly actions.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If paint can enter the paint roller interior, then the roller can be loaded with paint, but paint work its way into frame components interfering with function

Engineering Contradiction:
Improvepaint loading capacityVSAvoidpaint contamination of frame
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention accepts that paint will enter the roller interior for proper function, but converts this potential harm into a benefit by designing the frame with features that actively prevent paint from escaping the roller and contaminating the frame. The frame structure includes protective elements that utilize the paint containment need to further protect against contamination.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The invention introduces intermediate protective elements between the paint roller and the frame structure. These intermediaries act as barriers that prevent direct contact between any paint that might escape the roller and the frame components, thus eliminating the harmful contamination effect while maintaining the necessary paint loading function.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention is a paint roller system comprising a frame, a paint roller that may be supported by the frame. The frame may not include any moving parts. The paint roller may have end caps incorporated therein or connected thereto that may prevent liquids from entering the paint roller. The paint roller system of the present invention may be configured to prevent paint becoming lodged in elements of the paint roller system, and to prevent corrosion or plugging. The paint roller may rotate substantially freely when positioned within the frame. The paint roller system may be utilized to adhere paint to a surface with minimal effort or force being applied by a user. The paint roller system may include a paint roller container operable for storage of a paint roller as well as engagement and disengagement of the paint roller from the frame without the user handling the paint roller directly.
