Extension Adapter Assembly With Compression Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapter devices for attaching paint brushes to extension poles often fail to securely hold the brush in place, leading to potential detachment during use, especially when painting hard-to-reach areas.
Innovation Solution
A cylinder with two wells, one for the extension pole and another for the paint brush handle, featuring a nut with a compression fitting that securely grips the brush handle when tightened, preventing removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple clamp or sleeve is used to attach the paint brush to the extension pole, then the device complexity is reduced, but the reliability of attachment deteriorates
Solution Approach 1:
The adapter is divided into two separate halves that can pivot relative to each other. The first half contains a clamp mechanism while the second half contains a spring mechanism, allowing each segment to perform its specific function independently while working together to secure the brush handle reliably
Solution Approach 2:
The adapter employs a dynamic spring mechanism that provides continuous frictional force against the brush handle, and a pivotal joint that allows the clamp to open and close smoothly. This dynamic design enables reliable attachment without requiring complex rigid structures
2Ease of operation
If a friction-based grip mechanism is used, then the ease of operation is improved, but the reliability of attachment deteriorates
Solution Approach 1:
The invention combines two attachment mechanisms: a friction-based spring mechanism that provides continuous holding force and a mechanical clamp mechanism that provides positive locking. This merging of approaches ensures both ease of operation through the simple friction grip and high reliability through the mechanical lock
Solution Approach 2:
The pivotal joint acts as an intermediary between the clamp mechanism and the spring mechanism, allowing the system to transition smoothly between different attachment states while maintaining both ease of operation and reliable holding
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
The solution provides a secure attachment of the paint brush to the extension pole, allowing for effective painting of hard-to-reach areas without the risk of detachment, ensuring stability and ease of use.
Implementation Method 1
A compression fitting is positioned in the nut and the compression fitting compresses against the handle of the paint brush when the nut is tightened
Implementation Method 2
A nut is threadably coupled to the cylinder and the paint brush extends through the second nut

AI summary
An extension adapter assembly includes a cylinder that has a first well extending therein and a second well extending therein. The first well insertably receives an end of an extension pole and the second well insertably receives a handle of a paint brush for attaching the paint brush to the extension pole. A nut is threadably coupled to the cylinder and the paint brush extends through the second nut. A compression fitting is positioned in the nut and the compression fitting compresses against the handle of the paint brush when the nut is tightened. In this way the handle of the paint brush is inhibited from being removed from the second well.
