Solution Overview
Problem
Existing foam discharging devices struggle to consistently form foam into desired shapes, as they face challenges in adjusting discharge amounts and flow to multiple openings, limiting the ability to create shapes other than twisted three-dimensional forms.
Innovation Solution
A foam discharging nozzle with a foam diffusion space and multiple discharging openings, 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 supply opening, incorporating a porous element to stabilize and shape the foam discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If foam is discharged through multiple openings to form shaped products, then shape variety is improved, but discharge uniformity and formability deteriorate due to difficulty in adjusting discharge amounts and flow to multiple openings
Solution Approach 1:
A foam diffusion space is introduced as an intermediary between the foam supply opening and the foam discharging openings. This diffusion space allows foam to distribute uniformly before reaching multiple discharging openings, ensuring consistent discharge amounts and flow rates across all openings regardless of their positions, thereby maintaining formability while enabling shape variety
Solution Approach 2:
The invention transitions from a direct one-dimensional discharge path to a two-dimensional foam diffusion space followed by multiple discharge points. The foam diffusion space has a bottom area wider than the supply opening, creating a lateral expansion zone that enables uniform distribution before discharge, solving the uniformity problem while maintaining shape formation capability
2Manufacturing precision
If the bottom area of foam diffusion space is made wider than the supply opening to improve distribution, then foam discharge uniformity is improved, but device complexity increases
Solution Approach 1:
The foam diffusion space is merged with the nozzle body structure, and the porous element is integrated into the discharging openings. This consolidation achieves uniform foam distribution through the widened bottom area without requiring separate complex distribution mechanisms, thereby improving discharge uniformity while minimizing increases in device complexity
3Reliability
If porous elements are added to foam discharging openings to stabilize discharge, then foam formability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Porous elements are incorporated into the foam discharging openings to stabilize foam discharge and improve formability. These porous structures control foam flow and ensure consistent discharge characteristics. The porous elements can be integrated during molding or attachment, balancing the improvement in reliability with manageable manufacturing complexity

AI summary
A foam discharging nozzle (3) of the invention is a foam discharging nozzle (3) for a foam discharging device, including: a foam diffusion space (3B) to which foam produced by mixing a liquid and a gas is supplied from a foam supply opening (11) located on an upper side; and at least one foam discharging opening (13) formed in a bottom portion (12) of the foam diffusion space (3B). The area of the bottom portion (12) of the foam diffusion space (3B) is wider than the area of the foam supply opening (11). The centroid of the foam discharging opening (13) does not match the centroid of a supply opening projected portion (11A) formed by projecting the foam supply opening (11) onto the bottom portion (12) parallel to a central axis of the foam diffusion space (3B).
