Foaming Dispenser Liquid Passage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foaming dispensers face challenges in producing high-viscosity or gritty foams at low pressure and often suffer from clogging issues with scrub matter, particularly when dealing with liquid compositions containing additives like powders or abrasives.
Innovation Solution
The design incorporates a foaming dispenser with a mixing chamber, a porous member, and a liquid passage system that includes a first liquid passage and multiple second liquid passages allowing content liquid to flow in multiple directions, ensuring effective mixing with air to create foamy discharge without clogging, using a porous member to separate air and liquid flows and a fixing member to stabilize the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing foaming dispensers are used to produce high-viscosity or gritty foams, then the foaming function is provided, but clogging issues occur with scrub matter and additives like powders or abrasives
Solution Approach 1:
The liquid passage is divided into multiple second liquid passages that allow content liquid to flow in multiple directions (at least two directions) into the mixing chamber. This segmentation prevents clogging by distributing the flow path and reducing the likelihood of scrub matter blocking a single passage.
Solution Approach 2:
The liquid passage system transitions from a single linear flow path to a multi-directional flow system where content liquid can flow in at least two different directions. This dimensional change in flow paths enables the system to handle gritty and high-viscosity content liquids without clogging.
2Device complexity
If conventional liquid passage design is used, then the structure is simple, but it cannot effectively mix air and content liquid to produce foam without clogging
Solution Approach 1:
The liquid passage is segmented into a first liquid passage and multiple second liquid passages. This segmentation increases clogging resistance while maintaining reasonable structural complexity, as the multiple passages provide alternative flow paths for gritty content liquids.
Solution Approach 2:
The liquid passage system serves multiple functions: it transports content liquid from the container to the mixing chamber and provides multi-directional flow to prevent clogging. This multi-functionality achieves both structural efficiency and reliable operation with abrasive materials.
3Productivity
If high pressure is used to discharge foamy content liquid with additives, then discharge efficiency is improved, but the system becomes less suitable for low pressure operation
Solution Approach 1:
The system is designed to operate effectively across a range of pressures, particularly optimized for low pressure operation. The multi-directional liquid passages and mixing chamber configuration enable efficient foam production and discharge without requiring high pressure, thus maintaining adaptability across different pressure conditions.

AI summary
Systems, apparatuses, and methods for making content liquid foamy for discharge are described herein. A dispenser for making content liquid discharge foamy by mixing air flow from an air chamber with the content liquid flow from a liquid chamber can be provided. The dispenser can include a mixing chamber configured to mix air and content liquid; a porous member between an air passage from the air chamber and the mixing chamber; and a liquid passage from the liquid chamber to the mixing chamber. The liquid passage can have a first liquid passage and a plurality of second liquid passages. The liquid passage can be configured such that content liquid flows from the first liquid passage to the second liquid passages to the mixing chamber. The second liquid passages can be configured to provide flow of the content liquid in at least two directions.
