Innovation Solution
A box-shaped filtration device with grid panels and dual filtration bodies, where the inner filtration body has higher permeability than the outer, and specific buffer spaces for different filtration materials, preventing backflow and enhancing filtration efficiency and ease of replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an out-aquarium filtration barrel is used, then filtration effect is improved, but device volume and area occupation increase
Solution Approach 1:
The filtration device is designed to be nested within the aquarium tank structure, with the filtration chamber integrated into the tank wall. The inner filtration body is nested within the outer filtration body, and both are nested within the grid panels, creating a compact nested structure that provides effective filtration without occupying additional external space.
2Reliability
If a filter is installed at the upper or rear-end of the aquarium, then filtration effect is improved, but structural restriction and poor universality occur
Solution Approach 1:
The filtration device is designed with a standardized box-shaped structure that can be installed in various positions (upper, rear-end, or side of the aquarium) and integrated with different aquarium configurations. The device includes multiple connection interfaces and can function as both an internal and external filter, providing universal applicability across different aquarium setups.
3Ease of operation
If a submersible filter is used, then installation convenience is improved, but filtration section area and water filtration efficiency decrease
Solution Approach 1:
The filtration device is segmented into distinct functional zones: an inner filtration body for fine filtration, an outer filtration body for coarse filtration, and grid panels for structural support and flow distribution. This segmentation allows each component to be optimized for its specific function, maintaining high filtration efficiency while keeping the overall structure compact and easy to install.
4Ease of operation
If a cardcase-shaped filtration insert is used, then installation convenience is improved, but filtration body blocking and dirt backflow occur
Solution Approach 1:
Instead of allowing water to flow through a single-direction cardcase structure that blocks easily, the invention inverts the flow path design by using a dual-body structure with multiple flow channels. The inner and outer filtration bodies create parallel flow paths that prevent blocking, and the integrated design ensures dirt is contained and does not backflow into the aquarium during operation or maintenance.
5Ease of repair
If filtration consumable replacement is performed, then maintenance is simplified, but dirt backflow to aquarium occurs
Solution Approach 1:
The filtration consumables (inner filtration body, outer filtration body, and filtration materials) are designed as extractable components that can be removed separately from the main device structure. This extraction design allows maintenance personnel to replace consumables without disturbing the sealed containment structure, preventing dirt backflow into the aquarium while simplifying the maintenance process.
