Offset Handle Roller for Painter Control and Grip Comfort

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional roller handles do not provide adequate control or comfort for painters, leading to strained grip and reduced efficiency, especially when painting high areas or ceilings.

Innovation Solution

An offset handle design positions the painter's hand above the roller, featuring a dovetail groove and threaded extension for attaching a pole, allowing for easier grip and extended reach with the roller.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional roller handle is used (handle in line with roller), then the structure is simple, but the painter has poor control and strained grip

Engineering Contradiction:

Improvepainter control and grip comfortVSAvoidhandle structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The handle is offset from the roller axis, creating an asymmetric configuration where the handle does not align with the roller centerline. This asymmetric positioning allows the painter's hand to grip above the roller plane, providing better control and a more natural grip position while maintaining structural simplicity through the offset mounting arrangement.

Inventive Principle:

Principle #4Asymmetry

2Ease of operation

If the handle is offset above the roller plane, then the painter's control and grip comfort improve, but the handle cannot be positioned beneath the roller for overhead painting visibility

Engineering Contradiction:

Improvepainter controlVSAvoidadaptability to overhead painting

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system allows dynamic adaptation through the extensible pole mechanism. The handle is fixed in its offset position for optimal control during wall painting, while the telescoping or extendable pole provides the additional reach and angle adjustment capability needed for overhead and ceiling painting applications, making the system adaptable to different painting scenarios.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The roller handle system is divided into separable components: the offset handle assembly and an extensible pole section. This segmentation allows the handle to remain in its optimized offset position for control, while the detachable or extendable pole portion can be adjusted or extended to reach overhead areas, providing versatility without compromising the handle's primary positioning benefits.

Inventive Principle:

Principle #1Segmentation

3Length of moving object

If the handle is extended for high area painting, then the reach is improved, but the grip control may be reduced

Engineering Contradiction:

Improvehandle length for reachVSAvoidgrip control

Core Design Contradiction:

Length of moving objectVSEase of operation

Solution Approach 1:

The extensible pole provides dynamic length adjustment, allowing the painter to extend the handle only when reaching high areas is necessary. When painting at normal height, the pole remains retracted, maintaining the optimal grip control distance. This dynamic adjustment ensures that the painter retains maximum control during close-quarters work while gaining extended reach when needed for ceilings or high walls.

Inventive Principle:

Principle #15Dynamics

AI summary

The articles of manufacture a roller with an offset handle that is part of paint brush and roller system. The roller has an offset handle in which the painter grips above the plane of the roller. The handle is removable from the roller and can be used with different sizes of brush heads. The handle is designed such that the ordination of the roller's painting surface can be changed.
