Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam dispensing systems face issues with package failures, sputtering, noise, and residues due to premature foaming inside the package, especially when dealing with higher foam density, higher vapor pressure blooming agents, or delayed/blooming foams.
Innovation Solution
A package design with a flexible gas-impermeable inner container and a sealed rigid outer container filled with a driving gas, where the pressure of the driving gas remains higher than the vapor pressure of the emulsified liquid blooming agent throughout usage, controlling the pressure to prevent premature foaming and reduce residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vapor pressure of the blooming agent is increased to achieve better foaming performance, then the foaming capability is improved, but the risk of premature foaming and package failure increases
Solution Approach 1:
The patent changes the physical state of the blooming agent from gas to emulsified liquid form, which fundamentally alters its vapor pressure characteristics. This parameter change allows the blooming agent to remain stable at lower pressures during storage and transport, preventing premature foaming, while still achieving effective foaming when dispensed under controlled conditions.
Solution Approach 2:
The patent introduces an emulsion system as an intermediary between the blooming agent and the composition. The emulsified liquid form acts as a controlled-release mechanism, where the blooming agent is dispersed in droplets within the emulsion, preventing direct vaporization and premature foaming while maintaining the ability to foam when the emulsion is disrupted during dispensing.
2Productivity
If the foam density is increased to improve product performance, then the foaming quality is enhanced, but the likelihood of premature foaming inside the package increases
Solution Approach 1:
The patent changes the physical state of the blooming agent to emulsified liquid form, which allows the system to maintain high foam density capability while preventing premature foaming. The emulsion structure stabilizes the blooming agent in a non-volatile form during storage, but enables rapid foam generation with high density when dispensed, thus resolving the contradiction between foam quality and stability.
3Ease of operation
If the blooming agent is used in a delayed foam or blooming foam formulation to improve application characteristics, then the ease of application is enhanced, but the risk of package failure and sputtering increases
Solution Approach 1:
The emulsified liquid blooming agent acts as an intermediary that enables delayed foam formulations to work reliably. The emulsion structure allows the blooming agent to remain stable during storage and transport without premature foaming, while still providing the desired delayed foaming effect during application. This resolves the contradiction by using the emulsion as a controlled-release mechanism that prevents package failure while achieving the desired application characteristics.
