Compact device for producing foam for wellness and/or hygiene applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for producing foam for wellness and hygiene applications are limited by their small foam production capacity and require significant space, making them unsuitable for large-scale foam production and mobility.
Innovation Solution
A compact device comprising multiple vertically stacked vessels with air introduction systems to produce foam, where the foam from each vessel merges in an outlet region, increasing the foam volume with reduced water content and allowing for efficient reuse of water and foam components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single vessel is used for foam production, then the device structure is simple, but the foam production volume is limited and the device occupies more space
Solution Approach 1:
The patent transitions from a horizontal arrangement of vessels to a vertical stacking arrangement. Multiple vessels are arranged in tiers one above another, utilizing the vertical dimension to increase foam production capacity without expanding the device's footprint. The vessels are open towards an outlet region where foam merges, enabling high-volume foam production in a compact space.
Solution Approach 2:
The foam production system is divided into multiple independent vessels arranged vertically. Each vessel can independently produce foam, and the foams from different vessels merge in the outlet region. This segmentation allows the system to achieve high productivity while maintaining a compact base area, as each vessel contributes to the total foam output without requiring horizontal expansion.
2Quantity of substance
If more water and foam components are used, then larger foam volume can be produced, but resource consumption increases
Solution Approach 1:
The patent implements a water and foam component recovery system. Water and foam components that separate from the produced foam are collected and fed back into the vessels for reuse. This closed-loop approach allows the system to produce large volumes of foam while minimizing consumption of water and foam components, as these resources are continuously recovered and recycled within the system.
3Productivity
If the vessel height is increased to produce more foam, then foam volume increases, but foam destruction occurs when foam strikes the upper vessel sides
Solution Approach 1:
The upper sides of the vessels are formed with curved surfaces instead of flat or angled surfaces. This curvature design allows foam to flow smoothly along the curved path to the outlet region without striking against sharp edges or flat surfaces that would cause foam destruction. The curved geometry maintains foam integrity while enabling the vessels to accommodate sufficient mixture volume for high foam production.
