Pool Cleaning Cart with Adjustable Wheels and Rapid Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pool cleaning equipment, particularly the connection mechanisms between vacuum heads and poles, and the transportation of these devices, are inefficient due to wear and tear issues and lack of secure, rapid attachment systems, as well as inadequate cart designs for easy assembly and transportation over uneven surfaces.
Innovation Solution
A pool cleaning system featuring a rapid latch system for secure attachment of the vacuum head to a cradle on the cart, a pole coupler with a catch/snap mechanism to reduce wear on the vacuum head-pole connection, and a cart with adjustable wheels for navigating curbs and stairs, along with a debris collection system and motor protection features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard telescopic pole connection is used for the vacuum head, then the vacuum head can be attached to the pole, but the connection suffers from wear and tear and lacks security
Solution Approach 1:
The connection system is divided into separate components: a pole coupler with a quick-release mechanism that can be independently attached to the pole and then connected to the vacuum head. This segmentation allows each component to be optimized for its specific function, reducing wear on critical connection points.
Solution Approach 2:
The connection mechanism incorporates a dynamic quick-release system that allows the vacuum head to be rapidly attached and detached from the pole. This dynamic capability improves security during operation while extending durability by minimizing the time connection points are under stress.
2Productivity
If manual pool cleaning vacuum systems are used, then the vacuum head can clean the pool surface, but the user must manually move the vacuum head along the bottom surface which is labor-intensive
Solution Approach 1:
The vacuum head incorporates a self-propelling mechanism with wheels and a drive system that automatically moves the vacuum head along the pool bottom. The system serves itself by using the vacuum motor to drive the wheels, eliminating the need for manual pushing while maintaining cleaning effectiveness.
3Ease of operation
If a standard cart is used to transport pool cleaning equipment, then the equipment can be moved from location to location, but the cart is poorly constructed and does not offer features for easy assembly and transportation
Solution Approach 1:
The cart is constructed from modular components including a foldable frame, detachable shelves, and separable storage compartments. This segmentation allows the cart to be easily assembled and disassembled for storage or transport, while maintaining structural integrity during use.
Solution Approach 2:
The cart incorporates dynamic features such as collapsible handles, adjustable shelves, and foldable legs that can change configuration based on operational needs. These dynamic elements improve transportation convenience without significantly increasing overall construction complexity.
4Reliability
If the vacuum head is securely attached to the cart, then the vacuum head is stable during transport, but the attachment mechanism adds complexity to the cart design
Solution Approach 1:
The vacuum head attachment system uses a standardized interface that provides stable support at multiple equivalent points around the vacuum head. This equipotential distribution of support points ensures stability during transport while using a simple, repeatable attachment mechanism that does not add significant complexity.
