Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional facial masks contain harmful preservatives that can damage skin tissue, and their manufacturing process results in uneven thickness, leading to material waste and increased production and consumer costs.
Innovation Solution
A preservative-free facial mask manufacturing method using a specific blend of natural ingredients and advanced equipment, including a steam-jacketed kettle, drying mixer, mixing agitator, colloid grinder, coating machine, and drying machine, which ensures uniform application and instantaneous high-temperature sterilization, eliminating the need for preservatives and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If preservatives are added to facial mask liquid and paste to ensure freshness, then the product can be stored longer, but the preservatives harm human skin and can damage skin tissue
Solution Approach 1:
The patent removes preservatives from the facial mask formulation entirely. Instead of using chemical preservatives to extend storage life, the invention employs a preservative-free formula that relies on the inherent stability of its natural ingredients and proper packaging to maintain freshness without harmful additives.
Solution Approach 2:
The patent changes the chemical composition parameters by eliminating preservative ingredients and using natural, biodegradable components. This parameter change allows the product to achieve adequate shelf life through natural means rather than chemical preservation, resolving the contradiction between storage duration and skin safety.
2Ease of operation
If traditional facial mask is immersed in non-woven fabric, then the mask can be applied, but the mask becomes thicker with uneven adhesion, resulting in material waste and increased costs
Solution Approach 1:
The patent applies the facial mask slurry to the non-woven fabric in a controlled coating process before the product is used. This preliminary, uniform application ensures even distribution of the mask material, preventing both excessive thickness and material waste while maintaining ease of application.
Solution Approach 2:
The patent ensures uniform adhesion and thickness distribution across the facial mask by controlling the coating process. Each area of the non-woven fabric receives an consistent amount of mask slurry, eliminating the uneven adhesion problems of traditional immersed masks and reducing overall material usage.
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 method produces facial masks that are safer for human skin, reduce material waste, and lower production costs by using all-natural ingredients and advanced processing techniques, ensuring anti-corrosion and anti-bacterial effects without preservatives and minimizing microbial growth.
Implementation Method 1
transporting the non-woven cloth coated with the facial mask slurry into a fully closed thermostatic steam dryer, drying at 80-100° C. to form a facial mask, performing instantaneous high-temperature sterilization
Implementation Method 2
transferring the grinded paste liquid into a static liquid storage tank to defoam and forming a facial mask slurry; transporting the facial mask slurry into a coating machine; transporting the non-woven cloth coated with the facial mask slurry into a fully closed thermostatic steam dryer, drying at 80-100° C.
