Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam production devices for wellness and hygiene applications are limited by their small capacity, require significant space, and cannot be manually moved, as they produce a relatively small volume of foam and are not efficient in water and foam-forming component usage.
Innovation Solution
A device with multiple vertically stacked vessels that increase the surface area for foam generation, allowing for larger foam bubbles and reduced water and foam-forming component consumption, featuring adjustable air introduction and water level control systems to optimize foam production and reuse of settled components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single large vessel is used for foam generation, then a large volume of foam can be produced, but the device occupies a large amount of space and cannot be moved manually
Solution Approach 1:
The device divides the foam generation system into multiple separate vessels (at least two vessels) arranged vertically in a tiered configuration. Each vessel independently generates foam, and the combined foam volume from multiple vessels achieves the required large foam output without needing a single large vessel, thus reducing the device's overall footprint and improving portability.
Solution Approach 2:
The vessels are arranged vertically in a tiered configuration, transitioning from a horizontal spread layout to a vertical stacking layout. This dimensional change allows multiple foam generation surfaces to be stacked upward, increasing foam production capacity while minimizing the horizontal footprint of the device.
2Quantity of substance
If more water and foaming component are used, then a larger volume of foam can be produced, but resource consumption increases
Solution Approach 1:
The device incorporates a drainage system with channels that collect water and foaming components that settle out of the generated foam. These recovered liquids are redirected back into the vessels for reuse in subsequent foam generation cycles, reducing waste and minimizing the consumption of water and foaming components while maintaining high foam volume output.
3Productivity
If the surface area for foam generation is increased, then more foam can be produced per unit time, but the device occupies more space
Solution Approach 1:
Multiple vessels with foam generation surfaces are stacked vertically in a tiered arrangement. This vertical stacking increases the total foam generation surface area available for producing foam per unit time, while the compact vertical configuration minimizes the horizontal footprint of the device, thereby increasing productivity without proportionally increasing the device's occupied space.
4Quantity of substance
If conventional single-vessel devices are used, then the device structure is simple, but the amount of foam produced is relatively small compared to size
Solution Approach 1:
The device uses multiple separate vessels (at least two) instead of a single vessel, with each vessel having its own foam generation surface and being independently filled with the water-foaming agent mixture. This segmentation allows the combined foam output to be significantly larger than that of a single vessel of comparable individual size, while the modular nature of the segmented design keeps the overall structure relatively simple and manageable.
