Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam discharging devices can only form simple-shaped foam objects, lacking the capability to create elaborate three-dimensional designs.
Innovation Solution
The foam discharging device incorporates a discharging portion with ejection-port forming wall portions that have varying thickness and adhesive properties, allowing for the formation of complex shapes by controlling the height and shape of the foam body discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the ejection-port forming wall portion has uniform thickness, then the manufacturing process is simple, but the foam object cannot form elaborate three-dimensional designs
Solution Approach 1:
The ejection-port forming wall portion is designed with non-uniform thickness, where the thickness varies in the discharge direction. Specifically, the thickness is greater at the upper portion and smaller at the lower portion, allowing different sections of the wall to control foam discharge at different heights and rates, thereby enabling complex three-dimensional foam object formation
2Shape
If all wall portions have the same adhesive property, then the manufacturing process is simple, but the foam body cannot be discharged at different heights to form elaborate designs
Solution Approach 1:
Different wall portions of the ejection-port forming wall are provided with different adhesive properties. The adhesive property varies according to the position, with the upper wall portions having different adhesive characteristics from the lower wall portions. This allows the foam body to adhere at different heights and be discharged at controlled rates, enabling elaborate three-dimensional design formation
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 the creation of foam objects with intricate, elaborate three-dimensional designs by varying the adhesive properties and discharge patterns, enhancing the shaping capabilities of foam discharging devices.
Implementation Method 1
an adhesive property of the foam body relative to the lower edge of the first wall portion is stronger than the adhesive property of the foam body relative to the lower edge of the second wall portion

AI summary
A foam discharging device includes: a storage portion that stores a liquid agent; a foamer mechanism that changes the liquid agent into foam to generate a foam body; and a discharging portion that discharges the foam body. The discharging portion includes a foam passing chamber that allows the foam body to pass, and one or a plurality of ejection-port forming wall portions that extend downward below the foam passing chamber, are formed into a closed-loop shape in plan view, have the inner space communicating with the foam passing chamber, and have the lower edge having an ejection port formed thereon. At least part of the ejection-port forming wall portion has a bottom end portion formed into a shape that has a thickness reduced toward the lower side. The ejection-port forming wall portion and a second portion. The height position of a lower edge of the first portion is higher than the height position of a lower edge of the second portion.
