Solution Overview

Problem

Extension ladders lack a stable platform for securely holding a gallon paint can, making it difficult to access the paint handle for easy dipping of a brush.

Innovation Solution

A self-leveling one-gallon paint can holder attachment for extension ladders, featuring a circular aluminum cylinder that swivels, providing a stable and accessible platform for painting, and preventing the paint can handle from obstructing the brush.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional S-shaped wire holder is used to secure the paint can on an extension ladder, then the paint can can be held securely at height, but the paint can handle obstructs access for dipping the paint brush

Engineering Contradiction:

Improvesecure holding of paint canVSAvoidaccess to paint can handle

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent employs a spherical ball joint mechanism that allows the paint can holder to rotate and self-level. The spherical geometry enables multi-directional movement, allowing the holder to automatically orient the paint can handle toward the user while maintaining secure attachment to the ladder, thus resolving the obstruction problem without compromising security

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Device complexity

If a rigid fixed holder is used to attach the paint can to the extension ladder, then the structure is simple and strong, but it cannot adapt to different ladder angles and positions

Engineering Contradiction:

Improvesimplicity of holder structureVSAvoidadaptation to ladder angles

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic self-leveling mechanism using a ball joint and gravity-based leveling system. This allows the holder to automatically adjust its orientation based on the ladder's angle and position, providing adaptability to various working conditions while maintaining a relatively simple overall structure. The dynamic adjustment capability enables the holder to maintain proper paint can orientation regardless of ladder inclination

Inventive Principle:

Principle #15Dynamics

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

Enables safe and convenient painting from high heights by allowing the paint can and its contents to self-level, ensuring easy access for dipping the brush and enhancing the stability and usability of the paint can on an extension ladder.

Implementation Method 1

The one gallon paint can and it's contents self levels because of the circular fashioned aluminum cylinder that swivels
