Removable Battery Pack for Pool Cleaner Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile filters for swimming pools and similar water structures are cumbersome due to electrical or vacuum connections, making them difficult to maneuver manually, and lack a convenient and waterproof battery replacement system.
Innovation Solution
A mobile filter with a wheeled chassis, powered by a submersible electric motor and featuring a removable battery pack with a flexible electrical conductor that slides along a handle, allowing easy installation and replacement, and using IP65 underwater connectors to prevent water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery pack is integrated into the chassis, then the power supply is stable, but the maneuverability deteriorates due to increased weight and bulk
Solution Approach 1:
The battery pack is separated from the main chassis into a removable module that can be independently handled. This segmentation allows the heavy battery to be detached and placed separately, improving maneuverability while maintaining power supply reliability when attached.
Solution Approach 2:
The battery pack is positioned in a different spatial arrangement - suspended from the handle rather than integrated into the chassis body. This dimensional change in positioning reduces the moment of inertia and improves handling characteristics while maintaining electrical connection.
2Ease of operation
If the battery pack is made removable for easy replacement, then the ease of operation improves, but the electrical connection reliability deteriorates due to potential water ingress
Solution Approach 1:
A waterproof connector acts as an intermediary between the battery pack and chassis electrical contacts. This mediator component provides IP65-rated protection against water ingress while enabling reliable electrical connection and easy detachment for battery replacement.
Solution Approach 2:
The electrical connector incorporates waterproof sealing elements that create a protective barrier against water ingress. These sealing mechanisms allow the connector to maintain electrical contact while preventing water from reaching internal components during attachment and detachment operations.
3Ease of operation
If the battery pack weight is reduced for better maneuverability, then the ease of operation improves, but the power supply capacity deteriorates
Solution Approach 1:
The battery pack system transitions from a fixed weight to a dynamic configuration where the battery can be attached or removed based on operational needs. This allows the user to optimize between having full power capacity when the battery is attached and improved maneuverability when the battery is removed or partially detached.

AI summary
A mobile filter for removing solid contaminants from water such as swimming pools. The mobile filter has a handle maneuvered chassis, a powered propeller housed in a propeller housing, which propeller propels water through a removable bag mesh filter installable on the propeller housing. A submersible battery pack is slidably coupled to the handle, and is readily removable therefrom. An electrical conductor spans and connects the submersible battery pack and the submersible electric motor.
