Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aquarium maintenance practices, particularly water changes and filtration system servicing, are cumbersome, risk electrical failures, and lead to unhealthy aquarium conditions due to the need for external equipment and potential messes.
Innovation Solution
An integrated aquarium system with a removable filtration element and pump that allows for continuous water circulation and filtration, enabling easy servicing of filtration media and water changes without exposing electrical components or causing messes, by using a dry chamber to contain the filtration media and allowing for direct recirculation of water during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional external cooling systems and heating elements are used with electrical wires leading into the water column, then temperature management is achieved, but electrical failures and safety risks occur
Solution Approach 1:
The patent removes electrical components from the water environment by extracting the heating element from the water column and placing it in a dry chamber. The heating element is connected to the water indirectly through thermal conduction via the chamber wall, eliminating the need for electrical wires in the water and preventing electrical failures.
Solution Approach 2:
The dry chamber acts as an intermediary between the heating element and the water. The heating element heats the chamber wall, which then conducts heat to the water, providing thermal coupling without electrical coupling. This mediator approach maintains temperature control while isolating electrical components from water.
2Ease of repair
If filtration media is serviced by removing filter cartridges from the aquarium, then filtration maintenance is performed, but water spills and messes occur
Solution Approach 1:
The filtration system is segmented into a removable filter cartridge housed within a dry chamber. The dry chamber can be detached as a complete unit, allowing the filter cartridge to be serviced inside the dry chamber away from the aquarium water. This segmentation isolates the servicing process from the water environment, preventing spills and messes.
Solution Approach 2:
The filter cartridge is extracted from the water environment and placed inside a dry chamber. The entire dry chamber assembly can be removed from the aquarium, allowing filter maintenance to be performed in a dry environment away from the tank, eliminating water spills during the servicing process.
3Reliability
If water changes are performed by removing water from the aquarium, then water quality is improved, but the process is cumbersome and time-consuming
Solution Approach 1:
The dry chamber serves multiple functions: it houses the filtration media, provides a dry environment for filter servicing, and acts as a water collection reservoir during water changes. By integrating these functions into a single component, the system simplifies the water change process and reduces maintenance time while maintaining water quality.
Solution Approach 2:
The system enables self-service water changes by using the dry chamber as a collection point. Water can be diverted into the dry chamber for collection and disposal, or fresh water can be added through the chamber, allowing the filter housing to participate actively in the water change process without requiring separate equipment or complex procedures.
4Temperature
If multiple separate equipment are used for heating, cooling, and filtration, then each function is optimized, but device complexity increases
Solution Approach 1:
The patent combines the filtration system and heating element into a single integrated unit. The dry chamber houses both the filtration media and the heating element, merging two separate functions into one compact assembly. This reduces the number of separate equipment pieces in the aquarium while maintaining both filtration and temperature control functions.
Solution Approach 2:
The dry chamber is designed as a multi-functional component that simultaneously provides mechanical filtration housing, thermal heating, and a dry environment for electrical component protection. This universal design consolidates multiple functions into a single structure, reducing overall system complexity while maintaining optimized performance for each function.

Function Achieved in This Case
This solution maintains healthy aquarium conditions by ensuring continuous oxygenation and water circulation during maintenance, reduces the risk of electrical failures, and facilitates clean and efficient filtration media changes and water changes, enhancing the success rates of aquarium maintenance.
Implementation Method 1
a pump (30) disposed in a pump chamber (34)
Implementation Method 2
an external heating element is added to the tank to raise the temperature of the tank. These heating elements are fundamentally resistive heating elements contained within a waterproof plastic, glass, or metal housing
Implementation Method 3
The filtration system most typically incorporates a variety of filtration methods including mechanical (a coarse and sometimes fine filter material)

AI summary
An aquarium includes a first chamber arranged to contain a first volume of liquid, a dry chamber that is adjacent the first chamber and defines a second volume, and a removable element at least partially disposed within the dry chamber. The removable element is selectively removable from the dry chamber. The aquarium also includes a filter at least partially disposed within the removable element, and a pump including an intake and an outlet. The intake is arranged to draw a flow of liquid from the first volume of liquid during pump operation. The aquarium also includes a tube having a first end connected to the outlet and a second end movable between a first position in which the flow of liquid passes through the filter and is then discharged into the first volume and a second position in which the flow of liquid flows directly into the first volume.
