Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water discharging devices require air suction holes to generate bubbles, which complicates the manufacturing process, increases costs, and does not efficiently produce microbubbles for improved user experience.
Innovation Solution
A water discharging device design that eliminates the need for air suction holes by using a dispenser with specially configured dispensing holes and a jet regulation device to generate microbubbles from the water flow itself, creating a closed system that reduces air pollution and maintains microbubbles for longer periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If air suction holes are disposed at the annular wall of the housing to generate bubbles, then bubbled water can be formed, but the manufacturing process is complicated, mold development difficulty increases, and cost increases
Solution Approach 1:
The patent extracts the air suction holes from the housing structure and relocates them to the dispenser component. This separation simplifies the housing to a basic protective shell while concentrating the bubble-generating functionality in the dispenser assembly, thereby reducing manufacturing complexity and mold development difficulty.
Solution Approach 2:
The patent introduces a filter as an intermediary component between the water source and the dispenser. This filter serves multiple functions: it cleans the water before it enters the dispenser, and its presence facilitates the bubble generation process by controlling water flow characteristics, thereby achieving bubble generation without requiring complex housing structures with integrated suction holes.
2Object-generated harmful factors
If conventional air suction holes are used to generate bubbles, then water can be mixed with air, but microbubble generation efficiency is insufficient for improved user experience
Solution Approach 1:
The patent applies local quality by positioning air suction holes at specific locations on the dispenser where water flow creates optimal negative pressure conditions. The holes are strategically placed to maximize air entrainment efficiency, and the dispenser geometry is designed to concentrate water flow in a way that enhances microbubble generation at specific zones, thereby improving overall microbubble production efficiency.
Solution Approach 2:
The patent utilizes parameter changes by leveraging the dynamic pressure conditions created by water flow through the dispenser. As water flows through the restricted passages of the dispenser, local negative pressure zones are generated, which actively draw air in through the suction holes. The varying flow rates and pressure gradients transform the water-air mixing process, enabling efficient microbubble generation without external power sources.
3Ease of manufacture
If the dispenser has uniform diameter throughout, then manufacturing is simpler, but microbubble generation is less effective
Solution Approach 1:
The patent employs asymmetry in the dispenser design by creating a non-uniform diameter profile along the water flow direction. The dispenser features a narrower inlet section that gradually transitions to a wider outlet section. This asymmetric geometry is crucial for generating the pressure differential needed for effective microbubble formation, as it creates acceleration zones and negative pressure regions that uniform designs cannot achieve.
Solution Approach 2:
The patent addresses the manufacturing complexity issue by implementing the asymmetric diameter change primarily in the axial dimension (along the water flow direction) rather than requiring complex radial variations. This one-dimensional tapering approach maintains relative manufacturing simplicity while still achieving the necessary hydrodynamic conditions for effective microbubble generation, balancing ease of manufacture with functional effectiveness.

Function Achieved in This Case
The device effectively produces abundant microbubbles without external air intake, enhancing user experience through improved cleaning and maintaining a foamy effect, while simplifying production and reducing costs by eliminating the need for suction holes.
Implementation Method 1
water flows from the dispenser to the housing to form a negative pressure inside the housing, which negative pressure causes external air to be drawn into the housing from the suction holes
Implementation Method 2
a filter provided at an inlet end of the housing, the water flow entering the dispenser first passing through the filter to remove impurities in the water entering the dispenser
