Pool Cleaning Tool Neck Joint Reinforcement Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaning tools, such as rakes and brushes, suffer from weak neck joints that break easily under normal use, requiring frequent replacement and posing safety hazards during disassembly, and conventional metal-backed brushes are costly and ineffective in preventing breakage.
Innovation Solution
A modularly designed cleaning tool with a reinforcement member in the neck area, featuring angled sidewalls and a collar that circumscribes the handle, providing additional support and reducing the need for metal backing, along with removable corner brushes equipped with magnets for debris pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional metal backing is used to reinforce pool brushes, then manufacturing cost increases, but breakage resistance does not significantly improve
Solution Approach 1:
The patent removes the conventional metal backing from the brush head design. Instead of using metal reinforcement, the invention employs a modular plastic construction with an integrated reinforcement channel that receives a separate reinforcement rod, eliminating the need for expensive metal backing while maintaining structural integrity.
Solution Approach 2:
The patent uses composite construction by combining plastic brush head material with a separate reinforcement rod material. The reinforcement channel in the plastic housing contains the rod, creating a composite structure that leverages the advantages of both materials - the plastic provides corrosion resistance and the rod provides tensile strength.
2Ease of operation
If prior art disassembly methods are used with sleeve clips and frames, then tool-free assembly is difficult to achieve, but component replacement becomes cumbersome and dangerous
Solution Approach 1:
The patent divides the brush head into separable modular components - the brush body, corner brushes, and reinforcement elements can be independently replaced. The snap-fit design allows these segments to be easily attached and detached without tools, enabling safe and simple maintenance.
Solution Approach 2:
The patent employs a snap-fit mechanism as an intermediary between components that enables tool-free assembly and disassembly. The snap-fit features provide a safe intermediate state during assembly, allowing components to be easily connected and disconnected without requiring dangerous manual manipulation of clips or fasteners.
3Reliability
If reinforced metal backing is installed in brush heads, then manufacturing complexity increases, but breakage prevention remains ineffective
Solution Approach 1:
The patent employs a dynamic reinforcement system where the reinforcement rod is inserted into a channel rather than being permanently bonded. This allows the reinforcement element to flex and move with the brush head during use, adapting to various stress conditions while maintaining structural support.
Solution Approach 2:
The patent applies reinforcement only where needed - the reinforcement rod is positioned specifically in the channel within the brush head structure to provide localized strength at the critical joint areas, rather than requiring comprehensive metal backing across the entire brush head surface.
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 design significantly reduces breakage at the neck joint and eliminates the need for metal backing, enhancing durability and usability while allowing for easy assembly and disassembly without tools, and effectively picks up magnetic debris without additional tools.
Implementation Method 1
The corner brush head further comprises a magnet in communication with the channel

AI summary
A modularly designed cleaning tool such as a pool is provided with a reinforced neck area to substantially reduce breakage during use. The cleaning tool includes a brush head, a stem assembly, and a reinforcement fitting positioned at the joint area between the brush head and the stem assembly. The cleaning tool is adapted to mate with an elongated tubular pole or handle in a manner such that the pole or handle extends into the annular space defined by the reinforcement fitting and the stem assembly. The cleaning tool also includes a brush having an elongated frame and removable corner bristles extending therefrom. In some implementations, magnetic attachments are disposed on the brush frame and are adapted to pick up magnetic debris along a surface during cleaning.
