Solution Overview
Problem
Current Fluorescent Enhancement Theragnosis (FET) technologies used in medical and dental practices to identify and treat bacteria and viruses expose both practitioners and patients to harmful light, necessitating a solution to prevent inadvertent viewing while allowing controlled application for diagnosis and treatment.
Innovation Solution
Devices equipped with light-emitting diodes (LEDs) that emit specific wavelength ranges, including UV and blue light, are designed with filters and sensors to ensure controlled timed application, preventing harmful light exposure through the use of excitation and emission filters, and a sensor system to ensure proper positioning before activating the light, along with a viewing port for image capture and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blue and/or ultra-violet light is applied to identify and treat bacteria and viruses, then the ability to view and reduce bacterial activity is improved, but harmful light exposure to the eyes of practitioners and patients increases
Solution Approach 1:
The patent introduces an intermediary device (the light therapy device with integrated sensors and filters) that mediates between the harmful UV/blue light source and the human eyes. The device includes excitation filters and emission filters that selectively transmit only specific wavelength ranges, blocking harmful wavelengths while allowing therapeutic wavelengths to pass through. This intermediary structure enables the therapeutic function while protecting against harmful effects.
Solution Approach 2:
The patent applies parameter changes by precisely controlling the wavelength parameters of the light emitted. The device emits light in specific wavelength ranges (e.g., 380-425nm, 415-425nm, 460-480nm) while blocking other wavelengths. By changing and controlling the spectral parameters of the light, the device achieves therapeutic effectiveness while minimizing harmful exposure to human eyes.
2Object-affected harmful factors
If light filters and sensors are added to prevent harmful light exposure, then eye safety is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated device structure. The light source, excitation filters, emission filters, sensors for detecting proper positioning, and viewing ports are all combined into one unified device. This merging approach achieves the safety function through integrated filtration and sensing, while the compact design prevents the complexity from becoming excessive.
Solution Approach 2:
The device performs multiple functions simultaneously: it emits therapeutic light, filters harmful wavelengths, detects proper positioning through sensors, captures images through viewing ports, and provides real-time feedback. This multi-functionality is achieved within a single integrated device structure, making the added safety features part of the core device rather than separate additions.
