Deformable Cellular Screen for Complete Cosmetic Product Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product packaging devices with screens are complex to manufacture and do not efficiently allow for the uniform application and complete emptying of the product, lacking in user-friendly design and product control.
Innovation Solution
A device featuring a container with a cellular and deformable screen made from materials like polyurethane foam, allowing the screen to mold to the container's bottom and provide a large surface area for product access, enabling easy product pickup and complete emptying by being elastically deformable and having a concave shape towards the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional screen structure is used, then the device can be manufactured, but the manufacturing process is complex and the screen cannot efficiently allow for uniform application and complete emptying of product
Solution Approach 1:
The screen is made of cellular material with open porosity that allows product to pass through easily from the lower surface to the upper surface, enabling complete emptying of the container while simplifying the manufacturing process
Solution Approach 2:
The screen material is elastically deformable, allowing it to change shape and come into contact with the container bottom when product is used up, ensuring complete emptying while maintaining manufacturing simplicity
2Area of stationary object
If a traditional screen structure is used, then the device can function, but the screen does not provide a large surface area for product access and cannot mold to the container bottom
Solution Approach 1:
The cellular material provides a large surface area for product access while maintaining a simple screen structure that can be easily manufactured
Solution Approach 2:
The screen is made elastically deformable, allowing it to dynamically change shape and come into contact with the container bottom when product is used up, maximizing surface area utilization without adding structural complexity
3Loss of substance
If the screen is rigid, then the structure is simple, but the screen cannot come into contact with the container bottom when product is used up, leaving residual product
Solution Approach 1:
The screen material is elastically deformable, allowing it to change shape and come into contact with the container bottom when product is used up, ensuring complete emptying while maintaining reasonable structural simplicity
Solution Approach 2:
The cellular material provides both the necessary flexibility to contact the container bottom and the porosity to allow product passage, minimizing residual product without significantly increasing device complexity
4Ease of operation
If the screen does not have cellular material, then the manufacturing process is simpler, but the product cannot pass through easily and application is not uniform
Solution Approach 1:
The cellular material with open porosity allows product to pass through easily from the lower surface to the upper surface, enabling uniform application while the manufacturing process remains relatively simple
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 solution simplifies manufacturing, ensures complete product usage, and allows for controlled and uniform application of cosmetic products by allowing the screen to come into contact with the container bottom when empty, facilitating easy product access and minimizing residual product.
Implementation Method 1
the screen is able to mould itself to the shape of the bottom of the container when the product (P) in the container has been used up
Implementation Method 2
The cellular nature of the material constituting the screen can, in particular in the case of open porosity, allow the product contained in the container to easily pass through the screen from its lower surface to its upper surface
