Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scalp care devices using low-level laser therapy (LLLT) face challenges in evenly distributing laser light and maximizing hair loss treatment effects, often requiring multiple laser light sources that can lead to excessive heat generation and increased power consumption.
Innovation Solution
A light outputting device with a dome-shaped design featuring a plurality of light guide mechanisms that distribute laser light from a fewer number of high-intensity laser light sources, minimizing the number of sources and optimizing their placement for maximum hair loss treatment efficacy, while incorporating LEDs for broader scalp coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple laser light sources are used to evenly distribute laser light, then light distribution uniformity is improved, but heat generation and power consumption increase
Solution Approach 1:
The device divides the scalp treatment area into multiple zones and uses light guide mechanisms to distribute laser light from fewer sources across these zones, achieving even coverage without proportionally increasing the number of laser sources
Solution Approach 2:
Light guide mechanisms act as intermediaries between the laser light sources and the scalp, distributing and redirecting light to multiple areas, thereby reducing the need for multiple direct light sources and minimizing heat generation
2Productivity
If multiple laser light sources are used to maximize treatment coverage, then treatment effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
Each light guide mechanism serves multiple functions: it distributes light from a single source to multiple scalp zones, redirects light at appropriate angles, and ensures even coverage across different treatment areas, replacing what would otherwise require multiple dedicated light sources
Solution Approach 2:
The light guide mechanisms redirect laser light at various angles to reach different scalp zones, adding angular dimensionality to light distribution and enabling comprehensive coverage with fewer sources arranged in an optimized pattern
3Adaptability or versatility
If laser light sources are concentrated in specific areas, then treatment focus on problem areas is improved, but overall scalp coverage is reduced
Solution Approach 1:
The scalp is divided into multiple treatment zones with different light source densities, allowing concentrated treatment in problem areas while maintaining coverage in other regions through the light guide distribution system
Solution Approach 2:
Different regions of the scalp receive different intensities and distributions of light based on their specific needs, with problem areas receiving more concentrated light while other areas receive adequate coverage through the light guide mechanisms
