Solution Overview
Problem
Existing foam discharging devices struggle to form foam into desired shapes, as they fail to adjust discharge amount and flow effectively to multiple discharging openings, limiting the ability to create specific shapes beyond twisted three-dimensional forms.
Innovation Solution
A foam discharging nozzle with a foam diffusion space and multiple discharging openings at its bottom, where the area of the bottom portion is wider than the supply opening, and the centroids of the discharging openings do not align with the projected supply opening, allowing for stable formation of desired shapes by controlling the foam flow and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If foam is discharged through multiple openings to form specific shapes, then shape diversity is improved, but the ability to maintain stable foam flow and consistent discharge amount deteriorates
Solution Approach 1:
The foam diffusion space is divided into multiple regions with different discharging openings positioned at specific locations. Each opening discharges foam in a controlled manner, allowing formation of different shape portions. The segmentation of the diffusion space enables independent control of foam flow to each opening, maintaining stable discharge while achieving shape diversity.
Solution Approach 2:
Different portions of the foam diffusion space are given different properties by positioning discharging openings at specific locations with different areas. The local quality variation in terms of discharge area and position allows each opening to contribute differently to the overall foam shape, enabling both stability and shape control.
2Adaptability or versatility
If the bottom portion area is made wider than the supply opening to improve shape formation, then foam diffusion capability is improved, but the precision of discharge amount control to specific openings deteriorates
Solution Approach 1:
The bottom portion of the foam diffusion space is designed with varying local qualities through different discharging opening areas positioned at specific locations. This allows the overall wide area to provide good diffusion capability while each local opening maintains precise control over its discharge amount, resolving the contradiction between diffusion capability and control precision.

AI summary
A foam discharging nozzle of the invention is a foam discharging nozzle for a foam discharging device, including: a foam diffusion space to which foam produced by mixing a liquid and a gas is supplied from a foam supply opening located on an upper side; and at least one foam discharging opening formed in a bottom portion of the foam diffusion space. The area of the bottom portion of the foam diffusion space is wider than the area of the foam supply opening. The centroid of the foam discharging opening does not match the centroid of a supply opening projected portion formed by projecting the foam supply opening onto the bottom portion parallel to a central axis of the foam diffusion space.
