Interchangeable Choke Mixer for Adjustable Foam Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning sprays for home use cannot be easily adjusted to produce either dry or wet foam consistency, making them less versatile for cleaning different surfaces such as tiles, upholstery, and carpets.
Innovation Solution
A spray kit with a container, manual pump, and a mixer device that allows adjustment of air and liquid proportions by interchangeable mixer devices with varying choke diameters to produce desired foam consistencies, enabling the user to switch between dry and wet foam settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spray uses a fixed mixer device, then the structure is simple and easy to manufacture, but the adaptability to produce different foam consistencies is poor
Solution Approach 1:
The spray device is divided into modular components, specifically the mixer device that can be detached and replaced. This segmentation allows users to switch between different mixer devices with varying choke diameters to achieve different foam consistencies, while maintaining a simple overall structure when using a single fixed mixer device.
Solution Approach 2:
The spray device transitions from a static fixed mixer configuration to a dynamic interchangeable mixer system. Users can adjust the device by replacing mixer devices with different choke diameters (1.5mm, 2mm, 3mm) to adapt to different cleaning needs, making the device dynamically adaptable while keeping each individual mixer device simple in structure.
2Manufacturing precision
If the spray uses a single fixed choke diameter, then the device complexity is low, but the precision of foam consistency control is insufficient
Solution Approach 1:
The invention changes the physical parameter of choke diameter to control foam consistency. By providing mixer devices with specific choke diameters (1.5mm for dry foam, 2mm for medium foam, 3mm for wet foam), the system achieves precise control over foam moisture content and consistency, allowing users to select the appropriate mixer device for their specific cleaning requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to customize the foam consistency for specific cleaning tasks, improving the spray's adaptability and effectiveness on various surfaces by allowing precise control over the moisture content of the cleaning foam.
Implementation Method 1
a manual pump to increase the pressure of the air occupying the rest of the internal capacity of the container
Implementation Method 2
A dip pipe for the liquid picks this up close to the bottom of the container, driven by the pressure of the air present in the container
Implementation Method 3
The mixer device is also designed to produce a controlled mixture of the liquid originating from the container and air also from the container, which will give rise to the formation of a mass with a foam consistency
Implementation Method 4
between the lower end where the liquid enters and the opening where the air enters the mixer device has a choke with a cross-section whose specific value will give rise to different types of cleaning mass
Implementation Method 5
an outlet tube with a damping mass of felt at its delivery outlet
