Pool Net Flexible Rim and Pole Locking System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pool cleaning accessories, such as telescopic poles, brushes, nets, and vacuum heads, suffer from insecure attachment systems that lead to wobbling and inefficiencies, particularly due to reliance on spring-loaded clips and metal screws prone to rust and corrosion, and fail to effectively capture debris in pool corners and angles.
Innovation Solution
A locking system with a rectangular-like cross-section pole and toggle arm mechanism, along with accessory connecting elements that provide secure, multi-point attachment and adjustable angles for accessories like brushes and nets, and a flexible rim for skimmer nets to conform to pool surfaces, enhancing stability and maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-loaded plastic clip is used to attach accessories to the pole, then the attachment is simple and quick, but the connection is loose and causes wobbling
Solution Approach 1:
The attachment system is divided into multiple connection points (at least two holes positioned apart from each other) instead of relying on a single clip mechanism. This segmentation distributes the attachment forces across multiple locations, providing both simplicity of attachment and stability during use.
Solution Approach 2:
The invention combines multiple attachment features (multiple holes, optional threaded holes, optional flanges) into a single integrated accessory design. This merging allows the accessory to achieve secure attachment through multiple contact points while maintaining ease of installation through a unified attachment process.
2Reliability
If a threaded screw and nut system is used to attach accessories, then the connection is more secure, but it takes considerable time to change attachments
Solution Approach 1:
The attachment system allows for dynamic adjustment between different attachment modes. Users can quickly attach/detach accessories using the simple hole-and-clip method when speed is needed, or engage threaded holes for permanent installations requiring maximum security. The system adapts to different operational requirements.
Solution Approach 2:
The invention changes the attachment parameter from a single fixed method to multiple adjustable methods. By providing both simple hole alignment (for quick changes) and threaded holes (for permanent secure attachment), the system allows users to change the attachment parameter based on whether priority is speed or maximum security.
3Stability of the object's composition
If a hard rigid frame is used for skimmer nets, then the net structure is stable, but it scratches pool surfaces and cannot capture debris in corners
Solution Approach 1:
The invention replaces the traditional hard rigid frame with a flexible rim made of soft material. This flexible rim can deform to conform to pool surfaces and corners without scratching them, while still providing sufficient structural support to maintain net stability during skimming operations.
Solution Approach 2:
The net frame transitions from a static rigid structure to a dynamic flexible structure that can adapt its shape. The flexible rim allows the net to dynamically adjust to various pool geometries including corners and curved surfaces, enabling debris capture in previously inaccessible areas while maintaining operational stability.
4Device complexity
If brush head angle is fixed in one position, then the brush structure is simple, but the user cannot adapt to different cleaning needs
Solution Approach 1:
The brush head is designed with a pivotable connection to the pole, transforming it from a fixed static structure to a dynamic adjustable one. The brush can rotate or pivot to achieve different working angles while maintaining a relatively simple overall structure through the use of a straightforward pivot mechanism.

AI summary
A net for use with a pool cleaning system includes a net material portion and a frame body. The frame body has a flexible inner frame portion providing structural support but deformable when pressed against a surface, and an outer, flexible rim portion that is more malleable than the flexible inner frame portion and configured to provide a flexible rim edge for scooping.
