Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light therapy devices lack adequate variance in wavelength and power, making them impractical and uneconomical for treating a wide range of subjects without trained technician assistance, and struggle with inadequate penetration into deeper tissues due to strong absorption and scattering by blood and tissue components.
Innovation Solution
A light therapy device comprising a synergistic combination of light sources emitting at specific wavelengths (500-700 nm, 700-850 nm, 800-900 nm, and 850-1050 nm) to enhance penetration and therapeutic effects, including a controller for adjusting parameters such as power density and pulse rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If existing light therapy devices use single or limited wavelengths, then device simplicity is maintained, but penetration into deeper tissues is inadequate due to strong absorption and scattering
Solution Approach 1:
The light therapy device segments the light spectrum into multiple discrete wavelength ranges (first, second, third, and fourth wavelength ranges) with each set of light emitting elements targeting specific tissue depths and therapeutic needs. This segmentation allows the device to overcome absorption and scattering limitations by using different wavelengths for different penetration depths, while maintaining manageable device complexity through modular light emitting element arrays.
2Adaptability or versatility
If light therapy devices lack variance in wavelength and power, then manufacturing and operation remain simple, but they become impractical and uneconomical for treating a wide range of subjects
Solution Approach 1:
The light therapy device achieves universality by incorporating multiple sets of light emitting elements that can emit across four distinct wavelength ranges, allowing a single device to treat various conditions (inflammation, pain, tissue regeneration, wound healing) across different body areas and depths. The controller enables flexible configuration of wavelength combinations and power levels, making the device adaptable to diverse clinical needs without requiring multiple specialized devices.
Solution Approach 2:
The device incorporates dynamic control capabilities where the controller can independently adjust the power, pulse rate, and wavelength selection for each set of light emitting elements. This dynamic adjustability allows treatment parameters to be optimized in real-time based on the specific condition being treated, the body area targeted, and the desired penetration depth, thereby achieving high treatment versatility without permanently increasing device structural complexity.
3Reliability
If uniform light emission is used, then device operation is simple, but inadequate therapeutic effects are achieved due to varying tissue absorption and scattering properties
Solution Approach 1:
The light therapy device applies local quality by assigning different wavelength ranges and power levels to different sets of light emitting elements based on the specific therapeutic needs of different body areas. For example, shorter wavelengths may be used for superficial inflammation while longer wavelengths target deeper tissues. The controller enables independent adjustment of each light emitting element set, allowing the operator to tailor the light emission profile to match the local tissue properties and condition being treated, thereby improving therapeutic effectiveness while keeping operation straightforward through preset programs.
