Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional minute bubble generators require significant time and effort for assembly and adjustment due to the need to handle and assemble multiple small male thread members, leading to poor productivity.
Innovation Solution
A minute bubble generator with a colliding part integrated or separate from the flow path member, which simplifies assembly by eliminating the need for additional parts and adjustments, and is manufactured using a mold with a resin injection method to prevent molding failures and enhance productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple small male thread members are assembled into the flow path member, then the colliding part can be formed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent merges multiple separate male thread members into a single integrated colliding part that is molded as one piece with the flow path member. This eliminates the need to assemble multiple small components, thereby reducing assembly complexity and improving productivity simultaneously.
2Manufacturing precision
If multiple small male thread members are used to create the colliding part, then the flow path cross sectional area can be reduced, but the assembly and adjustment process requires considerable time and effort
Solution Approach 1:
The colliding part is pre-formed during the molding process with the exact cross sectional area reduction needed. This preliminary formation eliminates the need for post-assembly adjustments, allowing precise control of the flow path cross sectional area while saving significant assembly and adjustment time.
3Ease of operation
If male thread members with sharpened tips are screwed into the flow path member, then the colliding part can be created, but the handling and assembly become difficult
Solution Approach 1:
The patent combines multiple difficult-to-handle male thread members into a single colliding part that is integrated with the flow path member through molding. This merging eliminates the handling and assembly difficulties associated with multiple small components while maintaining the functional effectiveness of the colliding part.

AI summary
A minute bubble generator includes a flow path member including a flow path allowing a liquid to pass therethrough; and a colliding part provided in the flow path and generating minute bubbles in the liquid passing through the flow path by locally reducing a cross sectional area of the flow path. The colliding part is formed integrally with the flow path member and is provided closer to an upstream end or a downstream end relative to a lengthwise center of the flow path.
