Dermatoscope Polarization Control for Skin Lesion Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dermatoscope devices lack sufficient optical visibility and light irradiation adjustment capabilities, leading to suboptimal observation of skin lesions, as they do not effectively enhance resolution, reduce distortion, or allow for tailored light irradiation based on skin conditions.
Innovation Solution
A dermatoscope device with an optical tube structure, a light emitting unit, and a control module that includes multiple LEDs and polarizing plates, allowing for adjustable light polarization and brightness control, along with a focal length adjustor and battery-powered operation, to enhance optical resolution and reduce distortion while optimizing light irradiation for skin conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional dermatoscope devices use simple light irradiation or no polarization control, then the device structure remains simple, but the optical visibility and ability to clearly observe skin lesions is insufficient
Solution Approach 1:
The patent applies parameter changes by controlling the polarization state of light through voltage application to the liquid crystal layer. By changing the voltage parameter, the polarization direction of light is adjusted, enabling selective observation of skin lesions with different polarization states (parallel or perpendicular to skin surface), thereby improving optical visibility without significantly increasing device complexity
Solution Approach 2:
The patent implements dynamics by using a controllable liquid crystal polarization control unit that can dynamically adjust the polarization state of light during observation. This allows the observer to switch between different polarization modes (parallel and perpendicular) based on the specific skin condition being examined, enhancing the flexibility and effectiveness of lesion observation
2Adaptability or versatility
If conventional dermatoscope devices use fixed light irradiation, then the device structure remains simple, but the ability to optimize light irradiation for different skin conditions is limited
Solution Approach 1:
The patent implements dynamics by using a controllable liquid crystal polarization control unit that can dynamically adjust the polarization state of light during observation. This allows the observer to switch between different polarization modes (parallel and perpendicular) based on the specific skin condition being examined, enhancing the flexibility and effectiveness of lesion observation
