Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish tank cleaning devices require electricity to operate, posing safety risks and limiting their use.
Innovation Solution
A siphon fish tank cleaning device that utilizes a support assembly with a sucker for fixation and a pipeline assembly comprising a snake-shaped water pipe, a feeding portion floating on the water surface to collect oil dirt, and a discharging portion outside the tank, forming a siphon structure to autonomously discharge dirt without a water pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a water pump is used to clean the fish tank, then the cleaning efficiency is improved, but the device requires electricity which affects safety
Solution Approach 1:
The patent replaces the electrical water pump system with a mechanical siphon system. The siphon structure utilizes gravity and pressure differential to move water and oil dirt from the fish tank without requiring electrical power, thereby eliminating safety concerns while maintaining cleaning functionality.
Solution Approach 2:
The patent employs hydraulic principles through the siphon mechanism, where water flow is driven by pressure differential created by the height difference between the feeding portion and discharging portion. This hydraulic approach enables pump-free operation while achieving effective waste removal.
2Productivity
If a water pump is used to convey oil dirt, then the dirt discharge capability is improved, but the device complexity increases due to electrical components
Solution Approach 1:
The patent extracts and removes the water pump component from the system, replacing it with a simpler siphon-based conveyance mechanism. This extraction of the complex electrical pump while retaining the essential dirt discharge function simplifies the overall device structure.
Solution Approach 2:
The siphon structure is designed to automatically convey oil dirt without requiring external power sources or complex control systems. The system self-regulates through the natural pressure differential created by the height difference between intake and discharge points, eliminating the need for electrical components.
3Force
If the feeding portion is positioned high to enable siphon action, then the siphon force is improved, but the device height increases
Solution Approach 1:
The patent positions the discharging portion horizontally outside the fish tank rather than vertically above it. This spatial reconfiguration allows the system to achieve the necessary height difference for siphon action while minimizing the vertical profile of the device, effectively using horizontal space to resolve the height constraint.

Facilitates safe and efficient dirt discharge without electricity, ensuring convenient fixation and enhanced cleaning efficiency through a siphon action.
Implementation Method 1
a siphon structure is formed based on the feeding portion, the water pipe, and the discharging portion, so that the oil dirt is sucked by a siphon force
Implementation Method 2
the feeding portion is connected to a water inlet of the water pipe and floats on a water surface

AI summary
The present application provides a siphon fish tank cleaning device comprising a support assembly and a pipeline assembly. A feeding portion is connected to a water inlet of a water pipe and floats on a water surface, sucks oil dirt and conveys the oil dirt to the water pipe. A discharging portion is connected to a water outlet of the water pipe and located outside a fish tank, receives the oil dirt and discharges the oil dirt outside the fish tank. The discharging portion and the feeding portion are located inside and outside the fish tank respectively. A position of the discharging portion is lower than that of the feeding portion, and a siphon structure is formed based on the feeding portion, the water pipe and the discharging portion, so that the oil dirt is sucked by a siphon force, to facilitate autonomous discharge of the oil dirt.
