Innovation Solution
A water lifting device for pet water dispensers, featuring a housing with a lifting inner cavity, a stirring assembly, and a driving assembly. The device integrates the stirring and driving components into a modular housing, allowing for easy disassembly and cleaning, while keeping the driving assembly separate from the water to prevent electrical issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a submersible pump is used as water pumping power, then the device can effectively pump water, but the components become slippery and affected by dirt after long-term use, making them difficult to disassemble and clean
Solution Approach 1:
The water lifting device is divided into separate functional modules: a driving assembly (motor) housed in a first cavity, a stirring assembly in a second cavity, and a filter assembly in a third cavity. This segmentation allows each component to be independently accessed and cleaned without disassembling the entire device, resolving the contradiction between maintaining pumping efficiency and enabling easy cleaning.
Solution Approach 2:
The driving assembly is extracted from direct contact with water and placed in a separate first cavity, while only the stirring assembly contacts the water in the second cavity. This extraction of the motor from the water environment eliminates corrosion and makes the driving assembly easily removable for cleaning or replacement without exposing it to water damage.
2Productivity
If a submersible pump is placed below the liquid level, then water can be pumped effectively, but electric leakage risk increases when running for a long time
Solution Approach 1:
The device is segmented into electrically isolated zones: the driving assembly in the first cavity is separated from the water-contacting second cavity containing the stirring assembly. This spatial segmentation ensures that electrical components remain dry while water pumping functions are maintained through mechanical coupling via the stirring assembly, eliminating electric leakage risks.
Solution Approach 2:
The stirring assembly acts as an intermediary mechanism that transmits mechanical motion from the driving assembly to move water, without requiring direct electrical contact with water. The filter assembly serves as another intermediary, separating water flow while allowing mechanical drive transmission, thus maintaining electrical isolation while achieving water pumping functionality.
3Volume of moving object
If components are integrated into a compact structure, then the device size is reduced, but disassembly and maintenance become more difficult
Solution Approach 1:
The compact device integrates multiple assemblies (driving, stirring, filter) into different cavities within a unified housing structure. Each assembly is independently positioned in its own cavity with dedicated access points, allowing maintenance personnel to access and service specific components without disassembling the entire compact structure, thus maintaining both compactness and ease of repair.

Function Achieved in This Case
The solution facilitates easy cleaning and maintenance, maintains hygiene and safety, and prevents water pollution, thereby enhancing the user experience and ensuring the quality of the water provided to pets.
Implementation Method 1
The driving assembly drives the stirring assembly to rotate, to stir the water in the lifting inner cavity and provide a vorticity to make the water in the lifting inner cavity rotate, with a liquid level profile being in the shape of an inverted bell (parabola with an upward opening). High liquid levels on two sides will rise along an inner wall of the lifting inner cavity, and the water overflows to the water outlet portion
