Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning of filters is performed, then filters can be cleaned, but the operation is very long and laborious
Solution Approach 1:
The filter cleaning system operates automatically using the aquarium's own pump and water flow. The motor reverses the pump direction to create backwash flow that cleans the filter media, eliminating the need for manual intervention. The timer controls the cleaning cycles automatically, and the system uses the aquarium's existing water circulation infrastructure to perform the cleaning without external assistance.
2Ease of operation
If a tap system is installed at the bottom of the aquarium for filter cleaning, then filter cleaning is facilitated, but the system becomes complex and expensive
Solution Approach 1:
The aquarium's existing pump serves multiple functions: it performs both the normal water circulation/filtering operation and the filter cleaning operation by simply reversing its rotation direction. The same pump inlet and outlet pathways are used for both filtering mode and cleaning mode, eliminating the need for separate taps, valves, or piping systems. The motor can be controlled to rotate in either direction, making the single pump universally functional for both operations.
3Ease of operation
If a tap system is installed at the bottom of the aquarium, then filter cleaning is facilitated, but there may be leaks at the bottom where the tap is located
Solution Approach 1:
The tap and associated external piping system is completely removed from the aquarium design. Instead, the system uses the internal pump mechanism that is already integrated into the aquarium's filtration housing. The pump inlet is positioned to draw water from the aquarium bottom, and the outlet discharges to the filter media, eliminating any external connection points that could leak. All operations are contained within the aquarium's existing sealed structure.
4Productivity
If food is present in the aquarium during pumping, then animals are fed, but food is sucked and pumped inside the filtering device causing clogging
Solution Approach 1:
The system operates in periodic cycles, alternating between feeding mode and cleaning mode. During feeding mode, the pump operates normally to circulate water and distribute food. When cleaning is required, the pump direction is reversed to perform backwash cleaning of the filter media. This periodic switching prevents food particles from accumulating and clogging the filter, as the reverse flow periodically flushes out trapped debris. The timer controls these periodic transitions automatically.

AI summary
Filtering device (20) to draw water from an aquarium and the like and make water circulate inside, including a container (30) comprising a first housing portion (32) having a first inlet (174) and a second inlet (176) for the entry of water taken from the aquarium into the first housing portion (32) which is able to contain at least one filter for filtering water, further including a flow control device (50) having an entry (60) for taking water from the aquarium and it has two operating positions, a first operating position or filtering position wherein the entry (60) is in communication with the first inlet (174), so that water taken from the aquarium is put into the first housing portion (32), passes through the first inlet (174), is filtered and then is put back into the aquarium, and a second operating position or cleaning position or backwash position, wherein the entry (60) is in communication with the second inlet (176), water taken from the aquarium enters into the first housing portion (32) through the second inlet (176), so reversing the flow of water inside the first housing portion (32) and then is discharged so cleaning the filters.
