Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple components (vortex column, vortex column shell, pressurizing pipe, gas-liquid mixing pipe, hole mesh) are used to generate micro-bubbles, then micro-bubble generation effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple separate components (vortex column, pressurizing pipe, gas-liquid mixing pipe, and hole mesh) into a single integrated spray head structure. The spray head includes a body with an inlet, a Venturi tube structure formed within the body, and a hole mesh positioned at the outlet, all merged into one unified component that accomplishes the micro-bubble generation function without requiring separate assembly of multiple parts.
Solution Approach 2:
The spray head body serves multiple functions simultaneously: it acts as the housing structure, contains the Venturi tube for gas-liquid mixing, provides the outlet chamber, and positions the hole mesh for micro-bubble generation. This multi-functional design eliminates the need for separate components for each function, reducing overall device complexity while maintaining effectiveness.
2Productivity
If multiple components with connection structures are used, then micro-bubble generation function is achieved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple components into a single spray head assembly, eliminating the need for complex connection structures between separate parts. The integrated design reduces manufacturing steps, assembly operations, and associated costs while maintaining the complete micro-bubble generation function.
3Ease of manufacture
If a simplified one-piece spray pipe structure is used, then manufacturing cost and complexity are reduced, but micro-bubble generation performance may deteriorate
Solution Approach 1:
The simplified one-piece spray head structure successfully integrates all necessary functional elements (inlet, Venturi tube, hole mesh, and outlet) into a single component, reducing manufacturing complexity while maintaining effective micro-bubble generation performance through proper internal flow path design.
Solution Approach 2:
The Venturi tube structure within the one-piece spray head utilizes hydraulic principles to create negative pressure that draws gas into the water flow, enabling effective gas-liquid mixing and micro-bubble generation without complex external mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The simplified design enhances micro-bubble water generation performance while significantly reducing manufacturing costs and complexity, achieving efficient micro-bubble production with fewer components.
Implementation Method 1
A Venturi tube structure is formed in the one-piece spray pipe, and a suction port is provided on the one-piece spray pipe, so that a large amount of outside air can be sucked into the one-piece spray pipe through the suction port by means of a negative pressure produced by the Venturi tube structure
Implementation Method 2
The bubble water flows to the micro-bubble filter screen bag, and the bubble water is cut and mixed by the micro-bubble filter screen bag to produce a large amount of micro-bubble water containing a large number of micro-bubbles

AI summary
A micro-bubble spray head and a washing device with the same. The microbubble spray head comprises an integrated nozzle (521) and a microbubble filter bag (522) fixed in the outlet end (212) of the integrated nozzle (521), and a Venturi tube structure is formed in the integrated nozzle (521), and a suction port (216) is provided with the integrated nozzle (521), so that the air is sucked into the integrated nozzle (521) through the suction port (216) by means of a negative pressure made by the Venturi tube structure, and mixed with the water flow in the integrated nozzle (521) to produce bubble water; the microbubble filter bag (522) comprises an opening (223), a bottom (221) and a side wall between the opening (223) and the bottom (221), the opening (223) faces the venturi tube structure, and a outlet space (524) is formed between the side wall (222) and the inner wall (212a) of the outlet end (212), so that the bubble water can pass through the side wall (222) and the bottom (221) to form microbubble water. Not only the bottom portion (221) of the microbubble filter bag (522) participates in mixing and cutting of the bubble water, but also the side walls (222) of the larger area of the micro-bubble filter bag (522) also participate in mixing and cutting of the bubble water, so that the yield of the microbubble water of the microbubble spray head can be significantly increased.
