Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a low-cost, at-home imaging device or method for the early detection, monitoring, and treatment of acne for personal and point-of-care applications outside of professional dermatology offices.
Innovation Solution
A hand-held personal care implement using light treatment with a safety mechanism to control light emission, combined with a system and method for stitching images together to create a composite image of the skin, and monitoring changes in skin health to determine a skin evaluation or treatment routine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held personal care implement with light treatment is used for at-home acne detection and treatment, then accessibility and convenience are improved, but device complexity and safety control mechanisms are worsened
Solution Approach 1:
The system performs preliminary actions by detecting skin conditions (acne, wrinkles, pigmentation) before treatment begins. Image capture and analysis occur first to identify target areas, then light treatment is applied only to detected conditions. This preliminary detection phase enables the device to provide comprehensive skin analysis without requiring complex manual operation or professional intervention.
2Reliability
If light emission is controlled by ambient light sensing, then safety is improved, but device complexity is worsened
Solution Approach 1:
The device incorporates a light sensor that continuously monitors ambient light conditions and provides feedback to the controller. The controller adjusts light emission based on this feedback, preventing operation when ambient light is insufficient or when the device is not properly positioned on the skin. This closed-loop feedback mechanism ensures safe operation while using simple sensor-controller integration rather than complex safety systems.
3Measurement precision
If multiple images are stitched together to create composite skin images, then measurement precision is improved, but device complexity is worsened
Solution Approach 1:
The system divides the skin analysis task into segments by capturing multiple individual images of different skin areas and then stitching them together to form a comprehensive composite image. This segmentation approach allows detailed examination of specific conditions (acne, wrinkles, pigmentation) across the entire skin surface, improving detection precision while using standard image processing techniques rather than complex specialized systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables early detection and monitoring of acne, allows for effective treatment at home, and provides a means to assess the effectiveness of skin treatment routines without the need for professional dermatological services.
Implementation Method 1
an electromagnetic source for projecting electromagnetic radiation onto an area of skin, the electromagnetic source having emission characteristics to treat a skin condition
Implementation Method 2
a light sensor configured to sense an amount of ambient light present at the emitting end
Data Source
AI summary
In one embodiment, a system for monitoring acne is disclosed. A sensor device includes an image sensor and a position sensor. A processing device receives image data and position data from the sensor device. The processing device then combines portions of the image data for different images to generate composite image data, the combination being based on the corresponding position data for each image. A user interface displays a composite image of the user's skin based on the composite image data, the composite image including a skin condition indicator.
