Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic plates lack antimicrobial activities, which is a concern for hygiene and user resistance, especially in applications like fingerprint detection and home electric appliances.
Innovation Solution
A fiber optic plate is designed with a glass body containing silver oxide, providing antimicrobial properties through light absorbability and silver ion emission, while avoiding deterioration by separating the antimicrobial glass portion from Fe ions using a non-silver oxide covering layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fiber optic plate is made with conventional materials, then the transmittance and production are maintained, but the antimicrobial activities are lacking
Solution Approach 1:
The invention divides the fiber optic plate into three distinct segments: cores for light propagation, claddings for covering the cores, and a glass body for absorbing stray light and providing antimicrobial activities. This segmentation allows each component to be optimized independently, with the glass body specifically designed to contain silver oxide for antimicrobial properties without affecting the optical performance of the cores and claddings.
Solution Approach 2:
The glass body serves multiple functions simultaneously: it absorbs stray light that leaks from the cores and enters the claddings, and it provides antimicrobial activities through silver oxide content. This multi-functionality resolves the contradiction by adding antimicrobial capability without requiring separate components, thus maintaining production feasibility while achieving the desired reliability.
2Reliability
If silver oxide is contained in the glass body, then antimicrobial activities are achieved, but chemical durability deteriorates causing easy Ag ion emission
Solution Approach 1:
The invention converts the harmful effect of poor chemical durability into a beneficial antimicrobial function. The silver oxide in the glass body intentionally emits Ag ions due to moisture exposure, which would normally be considered a degradation mechanism, but here it serves the beneficial purpose of providing antimicrobial activities. The glass body contains silver oxide specifically to enable controlled Ag ion emission for sterilization purposes.
3Reliability
If the glass body contains silver oxide, then sterilization effect is obtained, but Fe ions coexistence deteriorates the sterilization effect
Solution Approach 1:
The invention extracts or removes Fe ions from the glass body composition to eliminate their harmful interference with the sterilization effect. By specifically excluding Fe ions while maintaining silver oxide content, the glass body can provide effective antimicrobial activities without the deteriorating influence of Fe ion coexistence. This selective material composition resolves the contradiction by removing the harmful element while preserving the beneficial one.
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 fiber optic plate achieves reliable antimicrobial activities without compromising transmittance or production difficulties, ensuring effective sterilization and maintaining optical characteristics.
Implementation Method 1
a glass body which is disposed among the cores and has light absorbability for absorbing stray light that leaked from the cores and entered the claddings
Implementation Method 2
the glass containing silver oxide does not have chemical durability, so that it has properties of easily emitting Ag ions due to moisture
Implementation Method 3
Ag ions have an excellent antimicrobial effect. Due to silver oxide contained in the glass body, the glass body can obtain a sterilization effect according to the action of Ag ions

AI summary
In an FOP 1, a glass body 8 is configured by including antimicrobial glass portions 10 made of antimicrobial glass containing Ag2O. Here, the glass containing silver does not have chemical durability, so that it has properties to easily emit Ag ions due to moisture. Ag ions have an excellent antimicrobial effect. Therefore, by configuring the glass body 8 to include the antimicrobial glass portions 10 containing Ag2O, the glass body 8 can obtain a sterilization effect due to the action of Ag ions. Therefore, the FOP 1 can be provided with antimicrobial activities.
