Bio-Cellulose Sheet Without Supporting Means for Cosmetic Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bio-cellulose sheets with supporting means face issues such as dryness, foreign material attachment, absorption of cosmetic compositions by the supporting material, inconvenient use, increased production costs, and potential health risks from synthetic preservatives like parabens.
Innovation Solution
A bio-cellulose sheet produced without a supporting means, using coconut as the primary material, and incorporating a plant extract preservative, which is sterilized and dehydrated, then pressed and cut to maintain moisture and prevent bacterial growth, reducing production complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a supporting means is attached to a bio-cellulose mask sheet, then the bio-cellulose sheet can be formed in a desired shape and handled during production, but the cosmetic composition is absorbed into the supporting means, reducing the effectiveness of the mask sheet
Solution Approach 1:
The invention extracts and removes the supporting means from the bio-cellulose mask sheet structure. By culturing bio-cellulose directly on a mesh and then removing the mesh, the final product consists only of the bio-cellulose sheet without any supporting fabric, thereby preventing cosmetic composition absorption by supporting material
Solution Approach 2:
The invention changes the physical parameters of the bio-cellulose by controlling its thickness (0.5-3.0 mm) and moisture content (40-90%) through specific culturing and drying processes, enabling the bio-cellulose to maintain structural integrity and desired shape without requiring a supporting means
2Ease of manufacture
If a supporting means is attached to a bio-cellulose mask sheet, then the bio-cellulose sheet can be handled during production, but the user must remove the supporting means before application, increasing usage complexity
Solution Approach 1:
The supporting means (mesh) is completely removed from the final product structure. The bio-cellulose is cultured on the mesh during production for structural support, then the mesh is extracted away, leaving only the flexible bio-cellulose sheet that can be directly applied to the face without removal steps
Solution Approach 2:
The bio-cellulose sheet becomes self-sufficient and self-supporting through controlled thickness and moisture content parameters, eliminating the need for external supporting means. The product serves itself structurally without requiring an additional supporting layer
3Ease of manufacture
If a supporting means is attached to a bio-cellulose mask sheet, then the bio-cellulose sheet can be handled during production, but the production process becomes more complex and costly
Solution Approach 1:
The supporting means is removed from the final product, simplifying the production process by eliminating the attachment step. The mesh is used only temporarily during culturing for structural support, then extracted away, reducing overall process complexity
Solution Approach 2:
The bio-cellulose is cultured with the desired thickness and structural properties in advance on the mesh, allowing it to be self-supporting after mesh removal. This preliminary structuring during culturing eliminates the need for subsequent supporting means attachment
4Reliability
If synthetic preservatives like parabens are used in bio-cellulose sheets, then bacterial growth is prevented, but potential health risks arise from accumulation in the human body
Solution Approach 1:
The invention uses naturally occurring, biodegradable components (bio-cellulose with high moisture content and plant extracts) that provide temporary preservation suitable for single-use cosmetic products, eliminating the need for persistent synthetic preservatives that accumulate in the body
Solution Approach 2:
The invention creates a composite preservation system combining bio-cellulose's natural properties (high moisture content creating unfavorable environment for bacteria) with plant extracts, replacing synthetic preservatives while maintaining effective bacterial growth prevention
