Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand in cosmetics, pharmaceuticals, and nutraceuticals for novel products that address gestural, sensorial, and galenic aspects, with existing technologies failing to provide innovative solutions for efficient and effective dispensing and preservation of liquid compositions within solid structures.
Innovation Solution
A product comprising a solid composition with high porosity and a liquid composition, where the liquid is housed in the cavities of the solid, offering unique sensorial handling, improved dispensing, and preservation, and allowing the use of potentially incompatible raw materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid composition is housed in the cavities of the solid composition, then the liquid composition is preserved and dispensing is improved, but the liquid composition may be difficult to extract when the product is nearly exhausted
Solution Approach 1:
The solid composition is designed with a porous structure containing multiple cavities that can store and release the liquid composition. The porosity allows the liquid to be retained during storage while enabling easy extraction through the porous matrix when needed, resolving the contradiction between preservation and extractability.
Solution Approach 2:
The liquid composition is nested within the cavities of the solid composition, creating a hierarchical structure where the liquid is contained within the solid matrix. This nesting arrangement allows the liquid to be protected during storage while remaining accessible through the porous structure for easy extraction.
2Ease of operation
If the second composition is scarcely viscous, then it can rise via capillarity into the cavities, but it becomes difficult to extract from the bottom of the holder when nearly exhausted
Solution Approach 1:
The porous structure of the solid composition provides capillary channels that allow low-viscosity liquid to rise and be stored within the cavities. The same porous structure enables easy extraction by allowing the liquid to flow out through the pores, resolving the contradiction between easy dispensing and reliable extraction.
3Quantity of substance
If the solid composition has high porosity, then raw material usage is reduced and handling properties are improved, but the structure may be weaker
Solution Approach 1:
The solid composition utilizes a porous structure with controlled porosity to reduce raw material usage while maintaining structural integrity. The porous architecture provides high surface area and volume efficiency, allowing reduced material content while preserving handling properties and structural strength through optimized pore distribution and size.
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
The product provides a novel galenic form, unique dispensing experience, enhanced user compliance, and reduced preservative content, with the liquid composition rising via capillarity to facilitate easy extraction, even when the product is nearly exhausted.
Implementation Method 1
the second composition is able to rise via capillarity into the cavities of the first composition, facilitating dispensing thereof

AI summary
A product includes at least one first composition and at least one second composition: the first composition is a solid composition comprising at least one cavity such that the composition has porosity greater than or equal to 20% by volume relative to the total volume of the solid composition; the second composition is a liquid composition, preferably in the form of a cream, and advantageously having viscosity higher than 5000 cps, and wherein all or part of the second composition is housed in all or part of the cavities of the first composition.
