Stable Foaming Composition for Non-Contact Diaper Rash Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating diaper rash in infants and toddlers require direct contact with the affected skin, leading to contamination risks and discomfort, and are difficult to apply accurately due to the thick, viscous nature of traditional creams.
Innovation Solution
A stable viscous foaming composition containing oil-soluble inorganic compounds like zinc oxide, high levels of organic oils, a foaming agent, a propellant, and a polymeric thickener, dispensed through a dispenser with a biased exit port that opens upon activation, allowing for targeted application without direct skin contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional thick cream is used to treat diaper rash, then effective skin treatment is provided, but the composition is difficult to spread and apply accurately
Solution Approach 1:
The patent changes the physical state and rheological parameters of the treatment composition by incorporating foaming agents and surfactants. This transforms the traditional thick cream into a foamable composition that can be easily dispensed and spread, while maintaining the therapeutic active ingredients for effective treatment.
Solution Approach 2:
The invention utilizes phase transition by creating a foam structure from the treatment composition. The foamable composition transitions from a dense cream state to an expanded foam state during application, improving spreadability and ease of application while delivering the same therapeutic benefits.
2Reliability
If hand application method is used to spread the cream, then adequate coverage is achieved, but contamination risk and discomfort increase due to direct contact
Solution Approach 1:
The patent introduces a foamable composition as an intermediary medium that can be dispensed through an applicator device. This allows the treatment to be applied without direct hand contact with the affected skin, reducing contamination risk while maintaining adequate coverage through the foaming action that facilitates even distribution.
Solution Approach 2:
The invention replaces the manual mechanical spreading action with a foam-based delivery system. The foamable composition can be dispensed and spread through gentler mechanical means or even self-spreading properties of the foam, eliminating the need for direct hand contact and reducing discomfort to the affected skin.
3Stability of the object's composition
If thick cream consistency is maintained, then treatment stability is preserved, but aesthetic appeal and user acceptance decrease
Solution Approach 1:
The patent modifies the physical parameters of the composition by incorporating foaming agents and surfactants, transforming it from a thick cream to a foamable formulation. This change improves aesthetic appeal and user acceptance while the underlying formulation maintains stability through proper ingredient selection and concentration control.
