Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV light radiation systems for neutralizing microorganisms, such as bacteria and viruses, pose health risks due to their interaction with human DNA and RNA, and require long exposure times, while alternative systems using lasers and photo-sensitizers are difficult to implement.
Innovation Solution
A system emitting UV light radiation with a narrow wavelength band, preferably between 1nm and 3nm, is used to induce optical resonance in microorganisms, ensuring the radiation is harmful only to the microorganisms and not human tissues, utilizing LED light sources or lasers with optical devices and filters to focus and select specific wavelengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UV light radiation is used to neutralize microorganisms, then the germicidal action is effective, but the radiation interacts with human DNA and RNA causing harmful effects
Solution Approach 1:
The patent applies local quality by using a specific narrow wavelength band (207-213 nm) that is selectively absorbed by microorganisms to induce optical resonance and neutralization, while this same wavelength band does not interact with human DNA and RNA. This creates a localized effect that is harmful only to the target microorganisms and safe for human tissues.
Solution Approach 2:
The patent changes the parameter of wavelength selection from broad UV spectrum to a narrow band (207-213 nm) that specifically induces optical resonance in microorganisms. This parameter change allows selective neutralization of microorganisms while avoiding interaction with human biological molecules, thereby resolving the contradiction between effectiveness and safety.
2Reliability
If UV light radiation is used to neutralize microorganisms, then the germicidal action is effective, but the exposure time required is sufficiently long
Solution Approach 1:
The patent employs periodic pulsed light radiation rather than continuous illumination. The system delivers high-intensity light pulses at specific intervals, which induces optical resonance in microorganisms during each pulse. This periodic action achieves effective neutralization in much shorter total exposure time compared to conventional continuous UV irradiation.
Solution Approach 2:
The patent maintains continuous useful action by using overlapping pulses that ensure continuous exposure of microorganisms to the neutralizing wavelength band. The pulsed delivery method with appropriate timing ensures that the germicidal action remains effective and continuous while minimizing total exposure time.
3Reliability
If lasers and photo-sensitizers are used to generate light radiation for neutralizing microorganisms, then the neutralization effect is achieved, but the system becomes difficult to implement
Solution Approach 1:
The patent extracts and eliminates the need for photo-sensitizers and complex laser systems by using a LED light source that directly emits the required narrow wavelength band (207-213 nm). This extraction of unnecessary components simplifies the system while maintaining the optical resonance neutralization effect.
Solution Approach 2:
The patent replaces expensive and complex laser systems with relatively simple and cost-effective LED light sources that can be mass-produced. The LED-based system is more economical and easier to manufacture while achieving the same germicidal effect through direct emission of the resonant wavelength band.
