Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic container puff sterilization methods using silver nanoparticles are prone to discoloration and skin penetration, causing harm and are expensive.
Innovation Solution
A puff sterilization patch made by weaving copper yarns into a net or fabric with a synthetic resin material, coated copper yarns, and an adhesive layer, providing a safe and cost-effective sterilization solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silver nanoparticles are used in the antibacterial member, then sterilization power is provided, but discoloration occurs and skin necrosis may be caused
Solution Approach 1:
The patent extracts the harmful silver nanoparticles from the sterilization system and replaces them with copper yarns that provide sterilization power without the harmful side effects of discoloration and skin penetration
Solution Approach 2:
The patent changes the material parameter from silver nanoparticles to copper yarns, maintaining the sterilization function while eliminating the harmful effects associated with silver nanoparticle usage
2Reliability
If silver nanoparticles are used in the antibacterial member, then sterilization power is provided, but manufacturing cost increases
Solution Approach 1:
The patent employs copper yarns that are more cost-effective than silver nanoparticles, reducing manufacturing costs while maintaining adequate sterilization functionality for the intended application lifecycle
3Shape
If copper yarns are woven into a net structure, then a fabric form is achieved, but structural complexity increases
Solution Approach 1:
The patent segments the sterilization patch into distinct functional layers (adhesive layer, copper yarn layer, synthetic resin layer) that can be manufactured separately and assembled, simplifying the overall manufacturing process despite the fabric structure
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 copper yarn-based patch effectively sterilizes without harming the body and offers a lower manufacturing cost while maintaining sterilization efficacy.
Implementation Method 1
a puff sterilization patch which is manufactured in the form of a net or fabric by using yarns made of copper having sterilizing power
Implementation Method 2
an adhesive layer provided on the underside of the pad layer
