Magnetic Pool Chemical Dispenser for Controlled Capsule Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment devices for swimming pools, such as floating and fixed dispensers, suffer from issues like rapid chemical dissolution, lack of versatility, and frequent replacement needs, and cannot maintain optimal chemical concentrations over time, especially when using encapsulated products.
Innovation Solution
A dosing device that attaches to the pool's internal surface, allowing gradual and controlled release of chemicals from porous capsules, with magnetic attachment for secure positioning, adjustable dosage based on pool size, and secure closure to prevent tampering, featuring a removable product holder for easy refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fixed dispensers are attached to the water delivery nozzle to force chemical dissolution, then chemical release speed is improved, but product duration deteriorates (short-lived)
Solution Approach 1:
The device extracts the chemical dissolution process from the high-velocity water delivery nozzle environment and relocates it to a stationary chamber positioned away from the direct water flow. This separation allows chemicals to dissolve gradually through controlled water access via through-openings, extending product duration while maintaining effective treatment.
Solution Approach 2:
The invention introduces an intermediary chamber structure that mediates between the water delivery system and the chemical capsules. The chamber acts as a buffer zone where water flow is moderated and distributed through controlled openings, enabling gradual chemical dissolution without the harsh conditions of direct nozzle injection.
2Manufacturing precision
If fixed dispensers are configured for specific nozzle dimensions, then chemical release control is improved, but device versatility deteriorates (cannot be interchanged)
Solution Approach 1:
The device achieves universality through a standardized mounting interface that can accommodate different pool types (above-ground and in-ground) and various nozzle configurations. The magnetic attachment system and universal chamber design allow the same device to function across multiple pool models and chemical capsule types, maintaining precision chemical release control while enabling broad interchangeability.
Solution Approach 2:
The dispenser is segmented into modular components: a universal mounting mechanism, a standardized chamber body, and interchangeable chemical capsule holders. This segmentation allows the core device to remain universal while accommodating different pool configurations and chemical types through simple component variations.
3Device complexity
If only one capsule is housed in the dispenser, then device complexity is reduced, but maintenance frequency deteriorates (frequent replacement needed)
Solution Approach 1:
The device merges multiple chemical capsule functions into a single integrated chamber, allowing several capsules to be housed simultaneously. This combination enables continuous chemical supply as capsules can be arranged in sequence or used together, significantly reducing maintenance frequency while maintaining manageable device complexity through standardized capsule compartments.
4Area of stationary object
If floating dispensers are used to allow free movement in water, then chemical distribution coverage is improved, but user convenience deteriorates (causes inconvenience)
Solution Approach 1:
The invention replaces the mechanical floating and moving system with a magnetic attachment system that secures the device to the pool wall. This substitution eliminates the unwanted free movement and floating behavior while maintaining effective chemical distribution through controlled water flow access, significantly improving user convenience.

AI summary
A dosing device for swimming pool water treatment, attachable to an internal surface of a swimming pool for the release of soluble chemicals, comprising: - an outer casing (2) with an inner chamber (6) and through openings (7) for communication between the inner chamber (6) and the exterior; - a product holder (3) housed in and removable from the inner chamber (6) of the casing (2); and - means of closing (5) and locking for immobilisation of the product holder (3) in the internal chamber (6) of the casing (2). The device comprises at least one magnetic attachment element (4) for removable and direct attachment of the casing (2) to the inner surface of the pool. Thanks to these magnetic attachment elements (4) the device can be temporarily and securely attached directly to the wall of any swimming pool without the need to alter it.
