Angle Converter Adapter for Brush Positioning on Extension Poles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional painting aids, such as extension poles attached to brushes or rollers, often fail to maintain the correct angle relative to the painted surface, necessitating the use of scaffolding or ladders for higher areas and causing ergonomic issues when painting low areas.
Innovation Solution
An angle converter adapter is introduced, allowing adjustable angles from 0 to 110 degrees in both directions, with 18-degree intervals, to ensure proper alignment of the brush or roller, reducing the need for scaffolding and improving ergonomics by enabling standing painting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a traditional extension pole is attached directly to a brush or roller, then the painting tool can reach higher areas, but the brush cannot be positioned at the correct angle relative to the painted surface
Solution Approach 1:
The painting tool is segmented into three main components: extension pole, angle converter adapter, and brush/roller. The adapter acts as an intermediate segment that provides angular adjustment capability between the pole and brush, allowing the brush to be positioned at correct angles while maintaining extended reach.
Solution Approach 2:
The angle converter adapter serves as an intermediary component between the extension pole and the brush/roller. It mediates the connection by providing a joint mechanism that allows angular adjustment, enabling the brush to achieve proper positioning relative to the painted surface while maintaining the extended reach of the pole.
2Ease of operation
If scaffolding or ladders are used to reach higher areas, then the brush can be positioned at the correct angle, but the device complexity and setup requirements increase
Solution Approach 1:
The angular adjustment function is extracted from the complex scaffolding or ladder systems and integrated into a compact adapter component. This allows the angle positioning capability to be achieved without the need for bulky external support structures, reducing overall device complexity while maintaining operational effectiveness.
Solution Approach 2:
The extension pole and angular adjustment mechanisms are merged into a single integrated painting tool system. The adapter combines the functions of connection and angular adjustment, eliminating the need for separate scaffolding or ladder equipment and reducing overall system complexity.
3Length of stationary object
If a straight extension pole is used for painting low areas, then the tool can reach lower positions, but work ergonomics deteriorate requiring crouching or low work positions
Solution Approach 1:
The adapter introduces dynamic angular adjustment capability to the painting tool. When painting low areas, the brush can be angled upward relative to the pole, allowing the user to maintain an upright standing position while the brush reaches downward surfaces, thereby improving work ergonomics without sacrificing reach depth.
4Adaptability or versatility
If the adapter allows extensive angle adjustment, then versatility for different painting surfaces improves, but the device complexity increases
Solution Approach 1:
The adapter provides angle adjustment beyond what might be minimally required (excessive action), offering 110 degrees of adjustment in each direction. This extensive range ensures versatility for all possible painting scenarios while the locking mechanism at 18-degree intervals prevents the complexity from becoming unmanageable by providing stable discrete positions.

AI summary
The invention relates to an angle converter adapter (1 and 2) designed to enhance the versatility of painting aids, such as extension poles (4) and brushes (3). Traditional extension poles, when directly attached to brushes or rollers, often maintain an incorrect angle relative to the painting surface. This angle converter adapter (1 and 2), positioned between the extension pole (4) and the painting tool (3), allows the angle to be adjusted from a straight position (1B) to 110 degrees in both directions, totaling a 220-degree range, and locks in place at approximately 18-degree intervals (1A and 1C). This adjustability ensures optimal paint coverage and application, whether painting high or low surfaces, thus improving work ergonomics and reducing the need for ladders or scaffolding. Constructed from plastic and metal, the adapter includes an upper part (1) with a specially sized taper for compatibility with common brushes (3) and rollers, and a lower part that accommodates either a taper (2) or universal screw (11) attachment for extension poles. The adapter components are connected via a purpose-designed j oint mechanism, allowing easy adjustment with a locking screw operable by hand. Key Features • Adjustable angle up to 220 degrees, lockable at 18-degree intervals. • Enhances painting efficiency and ergonomics for high and low surfaces. • Compatible with common brush and roller frames via a specially sized taper. • Dual attachment options for extension poles: taper and universal screw. • Easy to adjust and lock with a metal screw, requiring no tools.
