Cryogenic Pressurized Formulation for Shake-Free Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer products in pressurized cans often require vigorous shaking for consistent dispensing, leading to variable mixing and inconsistent experiences, and would benefit from being intensely cool upon dispensing.
Innovation Solution
A pressurized containment/dispensing system where a cryogenic, kinetically active formulation is created by co-mingling active agents with non-flammable and/or flammable liquid refrigerants under controlled pressure and temperature, allowing for dispensing without shaking and maintaining refrigerants in a liquid state for intense cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If products are dispensed from pressurized cans without shaking, then dispensing convenience is improved, but mixing consistency deteriorates
Solution Approach 1:
The formulation is pre-mixed at high speed under controlled pressure and temperature conditions during manufacturing, creating a homogeneous cryogenic composition before dispensing. This preliminary mixing action ensures consistent product distribution without requiring consumer shaking, resolving the contradiction between dispensing convenience and mixing consistency.
2Temperature
If liquid refrigerants are used for intense cooling, then cooling effect is improved, but safety deteriorates due to flammability
Solution Approach 1:
The invention changes the chemical parameters of the refrigerant system by using non-flammable liquid refrigerants (such as HFC-134a, HFC-125, or HFC-135a) instead of traditional flammable refrigerants. This parameter change maintains the cryogenic cooling effect while eliminating the fire hazard, resolving the contradiction between cooling performance and safety.
3Temperature
If refrigerants are kept in liquid state for cryogenic effect, then cooling performance is improved, but phase stability deteriorates under pressure changes
Solution Approach 1:
The invention uses a composite formulation containing multiple components including non-flammable liquid refrigerants, propellants, and active ingredients in specific proportions. This composite structure maintains phase stability under pressure changes while preserving the cryogenic cooling effect, resolving the contradiction between cooling performance and phase stability.
