Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet water dispensers face issues such as water overflow, contamination, and difficulty in adjusting water flow to suit different pet preferences, leading to inefficient water supply and potential noise disturbance.
Innovation Solution
A pet water dispenser design featuring a detachable inner assembly with a pump, water supply plate, and guide that allows adjustable water flow, integrated filtration, and UV sterilization, enabling pets to drink from a flowing surface or falling water, while preventing contamination and noise through variable pumping capacity and noise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water flow is increased to ensure adequate supply, then water supply efficiency is improved, but noise disturbance increases
Solution Approach 1:
The pump capacity is made variable rather than fixed, allowing the system to dynamically adjust water flow rates. The controller can modify pump operation to provide adequate water supply when needed while reducing flow during periods when pets are not present, thereby maintaining productivity while minimizing noise disturbance.
Solution Approach 2:
The system changes the operational parameters of the pump by adjusting its capacity. By varying the pump capacity according to detected pet presence or absence, the system optimizes water supply efficiency during active periods while reducing noise during inactive periods, thus resolving the contradiction between productivity and harmful noise generation.
2Productivity
If pump capacity is increased to improve water circulation, then water supply efficiency is improved, but energy consumption increases
Solution Approach 1:
The pump operates dynamically with variable capacity rather than at constant high power. The controller adjusts pump capacity based on actual water supply needs, ensuring efficient water circulation when pets are present while reducing energy consumption during periods when full circulation is not required.
Solution Approach 2:
The system modifies the operational parameters of the pump by changing its capacity setting. This allows the system to maintain high water supply efficiency when needed while operating at lower energy consumption levels during other times, effectively resolving the contradiction between productivity and energy use.
3Reliability
If water flow rate is increased to prevent stagnation, then water cleanliness is improved, but water overflow risk increases
Solution Approach 1:
The system incorporates feedback control through the controller that monitors water flow and pump operation. This feedback mechanism allows the system to adjust pump capacity to maintain adequate water circulation for cleanliness while preventing conditions that would lead to overflow, thus resolving the contradiction between reliability and harmful overflow effects.
Solution Approach 2:
The pump capacity is dynamically adjusted rather than operating at maximum flow continuously. This dynamic operation ensures sufficient water movement to prevent stagnation and maintain cleanliness while avoiding excessive flow rates that could cause overflow, effectively balancing reliability with harm prevention.

AI summary
A pet water dispenser may be configured such that water may fall or may flow along a surface. Such a pet water dispenser may include a water tank, a pump, a water supply pipe connected to the pump, and a water supply hole communicating with the water supply pipe. A water supply plate having an upper surface over which water supplied from the water supply hole flows and a plate support supporting the water supply plate to be above the water tank. The plate support may be an inclined surface or a vertical surface. When a large amount of water is pumped from the pump, water may drop directly from an edge of the water supply plate through a water guide back into the water tank. When a small amount of water is pumped, water may flow along an outer circumferential surface of the plate support to the water guide.
