Nanofiber Beauty Care Pack for Skin Adhesion and Ingredient Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beauty care packs face issues with insufficient adhesion to the skin, leading to ineffective ingredient transfer, excessive essence leakage, and discomfort, while hydrogel packs provide limited adhesion and require separate removal due to essence flow. Additionally, existing nanofiber-based solutions involve complex processes and potential solvent contamination.
Innovation Solution
A beauty care pack comprising a nanofiber web formed by simultaneous electrospinning of water-soluble polymers and functional materials, which is easily stored and applied as a dried sheet, providing effective ingredient absorption through moisture, preventing solvent-related skin troubles, and featuring a moisturizing layer and mesh support for enhanced absorption and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional beauty care packs are manufactured on woven or nonwoven fabric, then they provide basic structure and essence containment, but they achieve insufficient adhesion to the skin and cannot transfer ingredients effectively to deep skin layers
Solution Approach 1:
The patent changes the fundamental parameter of the base material from conventional woven or nonwoven fabric to a nanofiber membrane with fiber diameters of 1-100 nm. This parameter change in fiber dimension provides vastly increased surface area and contact points with the skin, achieving superior adhesion and ingredient transfer effectiveness without complicating the manufacturing process, as the nanofiber membrane is produced through electrospinning technology.
2Reliability
If excessive essence is added to conventional beauty care packs to improve adhesive strength, then adhesion improves, but the essence flows out during user movement causing discomfort and loss of active ingredients
Solution Approach 1:
The patent changes the physical state parameter of the essence from free liquid form to a gel state with controlled viscosity. This parameter change allows the essence to maintain strong adhesion to the skin without flowing out during user movement, preventing both discomfort and loss of active ingredients while achieving the required adhesive strength.
Solution Approach 2:
The patent creates a composite structure where nanofiber membranes are combined with gel-type essence containing active ingredients. This composite material system allows the nanofiber network to provide structural support and adhesion while the gel essence provides nourishment without excessive flow, solving both the adhesion and essence retention problems simultaneously.
3Ease of operation
If hydrogel beauty care packs are used to improve fit and allow daily activities, then comfort and mobility improve, but the packs become too thick causing limited adhesion and require separate removal
Solution Approach 1:
The patent changes the dimensional parameter of the beauty care pack by transitioning from thick hydrogel structure to ultra-thin nanofiber membrane with thickness of 1-100 nm. This parameter change provides excellent conformability to skin contours for comfort during daily activities while maintaining strong adhesion through the high surface area-to-volume ratio of the nanofiber structure, eliminating the need for separate removal.
4Reliability
If double-layered nanofiber structure with plasma treatment is used to improve skin contact, then adhesion and ingredient transfer improve, but the process cost increases and the structure becomes complex
Solution Approach 1:
The patent changes the fiber diameter parameter to the nanoscale range of 1-100 nm, which inherently provides vastly increased surface area and skin contact area compared to conventional microfiber structures. This single parameter change achieves superior adhesion and ingredient transfer without requiring complex multi-layer constructions or additional plasma treatment processes, simplifying the overall manufacturing approach.
