Liquid Dispensing Device Segmented Nozzles and Rotational Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensing devices for sinks face challenges in efficiently dispensing sterilized water, as they often mix sterilized water with purified water, leading to contamination issues, and the coupling structure between the discharge part and the sink is difficult to manage, especially in narrow spaces, affecting workability and the ability to maintain desired water temperatures.
Innovation Solution
A liquid dispensing device with separate nozzles for purified, cold, hot, and sterilized water, featuring a unique coupling structure that allows for independent rotation and easy access, along with a sterilized liquid module and valves to manage water flow, ensuring sterilized water is used only when needed and maintaining desired temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sterilized water and purified water are discharged through one cock, then the device complexity is reduced, but the purification reliability deteriorates due to mixing and contamination
Solution Approach 1:
The single discharge cock is segmented into multiple separate discharge nozzles (first discharge nozzle for purified water, second discharge nozzle for sterilized water). This segmentation allows each type of water to be discharged through dedicated pathways, preventing mixing and contamination while maintaining a relatively simple overall device structure.
Solution Approach 2:
The sterilized water discharge function is extracted from the common discharge pathway and separated into a dedicated second discharge nozzle. This extraction ensures that sterilized water, which contains hypochlorous acid, does not mix with purified water in the discharge tube, thereby maintaining purification reliability.
2Shape
If the coupling structure is installed below the sink, then the aesthetic appearance is improved, but the ease of operation deteriorates due to narrow working space
Solution Approach 1:
The discharge part is designed with rotational capability, allowing it to rotate relative to the coupling structure. This dynamic feature enables the discharge nozzles to be positioned in different orientations, making it easier to access and manipulate the valves and coupling structure during installation and maintenance, thereby improving ease of operation without compromising the concealed aesthetic appearance when in use.
Solution Approach 2:
The discharge part is designed to extend in multiple dimensions - vertically upward from the coupling structure and horizontally outward for discharge. This multi-dimensional configuration allows the discharge nozzles to be positioned away from the narrow space below the sink, improving accessibility for operations while maintaining the concealed aesthetic appearance of the coupling structure.
3Device complexity
If remaining sterilized water is not drained, then the device complexity is reduced, but the harmful factors increase due to precipitation and erosion
Solution Approach 1:
A drainage valve is provided that can be operated to drain remaining sterilized water from the discharge tube before normal operation or maintenance. This preliminary drainage action prevents the precipitation and erosion problems that would occur if sterilized water remained in the tube, without requiring a complex continuous drainage system.
Solution Approach 2:
The drainage function is designed to be manually operable by the user, allowing them to drain remaining sterilized water when needed. This self-service approach eliminates the need for complex automatic drainage systems while still preventing the harmful effects of remaining sterilized water through periodic manual drainage.

AI summary
Provided is a liquid dispensing device. The liquid dispensing device includes an internal member coupled to a sink and a nozzle. A liquid processing module is installed separately from the dispenser and may include components to generate, for example, a heated liquid, a cooled liquid, or a liquid having a sterilizing agent. Piping coupling the liquid processing module to the nozzle may extend through the internal member, and one or more components may couple the internal member under the sink. One or more valves may be positioned on the piping to direct fluid from the liquid processing module to the nozzle or to discharge fluid.
