Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for producing high-quality food foams, such as milk foam, are complex, difficult to clean, and lack precision in controlling foam quality, making them unsuitable for home use and requiring frequent cleaning, which is time-consuming and prone to product contamination.
Innovation Solution
An inline fluid foaming device with a controlled air valve and a centrifugal pumping and foaming element, configured as a single disc with patterned and smooth surfaces, applies high shear stress to mixtures of fluid and air, allowing adjustable foam density and integration with a heating unit for temperature control, simplifying the system and enabling easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional whisk-based foaming devices are used, then foam can be produced, but the process requires time, multiple manipulations, and frequent cleaning
Solution Approach 1:
The invention extracts the foaming function from traditional whisk-based devices and integrates it directly into the beverage dispensing nozzle. The foaming element is built into the nozzle structure, eliminating the need for separate whisk attachments and reducing cleaning requirements to simple nozzle maintenance.
Solution Approach 2:
The invention merges the foaming mechanism with the beverage dispensing system. The nozzle serves dual purposes: dispensing liquid and creating foam through integrated air injection and shear stress generation, eliminating separate foaming devices and their associated cleaning needs.
2Manufacturing precision
If complex foaming systems with multiple components are used, then foam quality can be controlled, but device complexity increases and cleaning becomes cumbersome
Solution Approach 1:
The nozzle serves multiple functions: it dispenses liquid, injects air, generates shear stress for foam creation, and controls foam density. This multi-functionality eliminates the need for separate components for each function, simplifying the overall system while maintaining foam quality control.
Solution Approach 2:
The invention controls foam quality by adjusting parameters such as air injection rate, liquid flow rate, and nozzle geometry rather than adding complex mechanical components. This allows precise foam control through parameter optimization while keeping the device structure simple.
3Measurement precision
If traditional foaming devices are used, then foam can be produced, but regulation and control of foaming is complicated and not precise
Solution Approach 1:
The system incorporates feedback control through sensors that monitor foam characteristics and adjust air injection and liquid flow rates accordingly. This closed-loop control ensures precise foam regulation while maintaining simple device architecture through automated parameter adjustment.
Solution Approach 2:
The invention replaces complex mechanical foam control mechanisms with fluid dynamic control through adjustable air injection and shear stress generation. This substitution of mechanical control with fluid-based control simplifies the device while improving precision through easier parameter adjustment.
4Reliability
If frequent cleaning is required, then product contamination is prevented, but time consumption increases and user attraction decreases
Solution Approach 1:
The invention extracts the foaming function from removable components and integrates it into the fixed nozzle structure. This eliminates the need to disassemble and clean separate foaming attachments, reducing cleaning frequency to simple nozzle rinsing while maintaining product safety.
Solution Approach 2:
The nozzle design allows for easy self-cleaning through simple rinsing or flushing operations. The integrated structure enables users to maintain cleanliness without complex disassembly procedures, making routine maintenance quick and attractive for home use.
