Water Dispenser Dual Pump High Outlet Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water dispensers face insufficient water pressure when the water outlet is positioned high due to limited internal space, requiring a low water outlet position to discharge water by gravity.
Innovation Solution
The water dispenser employs two pumps, a first water pump for cold water and a second water pump for warm water, which communicate directly with the water outlet component, increasing water pressure and allowing the outlet to be positioned higher without the need for a water pump near the water source, optimizing internal space and balancing the center of gravity for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single water pump is used to pump water from one side of the water inlet, then the device complexity is reduced, but the water pressure becomes insufficient when the water outlet component is positioned at a high position
Solution Approach 1:
The patent divides the water pumping function into two separate water pumps: a first water pump for pumping water to the water cooling module and a second water pump for pumping water to the water heating module. This segmentation allows each pump to independently generate sufficient water pressure for its respective module, resolving the pressure insufficiency issue that occurs with a single pump configuration when the outlet is positioned high.
2Stress or pressure
If the water outlet component is positioned at a low position, then the water pressure requirement is reduced, but the adaptability of the water dispenser is limited
Solution Approach 1:
The patent employs hydraulic principles by using two water pumps to actively generate and maintain water pressure in the system. This allows the water outlet component to be positioned at various heights without relying on gravity alone, enabling flexible installation positions and improving the adaptability of the water dispenser to different installation environments.
3Stress or pressure
If two water pumps are used to increase water pressure, then the water outlet can be positioned at a high position, but the device complexity increases
Solution Approach 1:
The two water pumps in the patent serve multiple functions: they not only increase water pressure to enable high-position outlet placement, but also independently supply water to different functional modules (cooling and heating). This multi-functionality justifies the increased device complexity by providing both pressure enhancement and modular water distribution capabilities.

Function Achieved in This Case
This configuration enables the water dispenser to discharge water at a higher position with increased pressure, utilizing smaller pumps to maximize internal space and improve stability by balancing the center of gravity, while maintaining efficient water output.
