Pool Cleaner Removable Cover and Handle Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled pool cleaners often require complex maintenance procedures due to internal components being fouled by debris, which involves multiple latches and screws for access, making maintenance difficult for users.
Innovation Solution
A wheeled pool cleaner with a removable cover and handle closure system that allows easy access to internal components, featuring an inner cover to protect the turbine and gears, and solid inner walls to prevent debris entry, facilitating maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple latches and screws are used to secure the access cover, then the internal components are securely enclosed, but the maintenance procedure becomes complex and difficult for users
Solution Approach 1:
The pool cleaner body is segmented into multiple access openings, each with its own removable access cover. This allows users to access specific internal components without having to open the entire cleaner body, simplifying maintenance while maintaining secure enclosure of other components.
Solution Approach 2:
The access covers are designed to be completely removable from the cleaner body, extracting the need for complex fastening mechanisms. Users can simply remove the cover to access internal components and then reattach it, eliminating the need to manipulate multiple latches and screws.
2Ease of operation
If the cleaner body is opened for maintenance, then internal components can be accessed, but debris may enter and foul the components during the maintenance process
Solution Approach 1:
Users are instructed to remove the pool cleaner from the water and perform maintenance on a dry surface before reattaching the access cover. This preliminary action sequence prevents water and debris from entering the cleaner body during the maintenance process, eliminating the need for complex sealing mechanisms.
3Reliability
If the access cover is securely fastened, then internal components are protected from debris, but the cover becomes difficult to remove for maintenance
Solution Approach 1:
The access covers are designed to be completely removable from the cleaner body, extracting the need for complex fastening mechanisms. Users can simply remove the cover to access internal components and then reattach it, eliminating the need to manipulate multiple latches and screws.
Solution Approach 2:
The access covers use simple, inexpensive fastening mechanisms that are easily replaced or reattached. The design prioritizes ease of removal and reattachment over permanent secure fastening, allowing users to quickly service the cleaner without investing in complex locking systems.

AI summary
A pool cleaner includes a pool cleaner body and at least two wheels mounted to the pool cleaner body so as to be rotatable about a common wheel axis. An access cover selectively closing an access opening defined in the body. A handle closure is mounted to the body so as to be rotatable about the common wheel axis independently of the at least two wheels. The handle closure is rotatable relative to the body so as to be movable between a closed position, in which the handle closure secures the access cover over the access opening, and an open position. An inner cover can selectively cover a turbine and gears of the pool cleaner within the body, and is held in place via engagement with the access over. Wheel well sidewalls can be substantially solid to help further enclose an inner volume of the body.
