Solution Overview
Problem
Current skin treatment methods lack a comprehensive solution that effectively combines physical cleansing, sanitization, and phototherapy to address various skin issues such as aging, acne, and inflammation while allowing for the application of skin care ingredients and temperature-based therapies.
Innovation Solution
A light therapy device with a translucent head plate and rotatable applicator disc that incorporates multiple light sources, temperature control, and interchangeable surface elements, enabling simultaneous phototherapy, skin cleansing, and application of ingredients, with adjustable light frequencies and temperature settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple treatment functions (cleansing, phototherapy, temperature therapy) are combined into a single device, then treatment comprehensiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple treatment functions (physical cleansing via brush, phototherapy via LED lights, temperature therapy via heating/cooling elements, and ingredient application) into a single handheld device. The brush head integrates all these components, allowing simultaneous or sequential delivery of multiple treatments during one application session, thereby improving treatment comprehensiveness while managing device complexity through integrated design.
Solution Approach 2:
The device is designed as a multi-functional tool that can perform various skin treatments depending on the attached brush head and activated features. Different brush heads (soft, medium, firm, exfoliating) can be interchanged, and the device can switch between light frequencies (red, blue, green, yellow LEDs), temperature modes (heating, cooling, or ambient), and cleansing intensities, making it a universal skin treatment device that adapts to different skin concerns and treatment protocols.
2Reliability
If multiple light sources with different frequencies are used, then phototherapy effectiveness is improved, but energy consumption increases
Solution Approach 1:
The device employs different light frequencies (red, blue, green, yellow LEDs) that can be activated periodically or sequentially based on treatment needs. The controller enables selective activation of specific LED wavelengths for different skin concerns (e.g., blue light for acne, red light for anti-aging), allowing the system to deliver comprehensive phototherapy effectiveness while consuming energy only when and where needed, rather than continuously operating all light sources.
3Productivity
If physical cleansing and ingredient application are combined, then treatment efficiency is improved, but risk of ingredient contamination increases
Solution Approach 1:
The device employs separable, interchangeable brush heads that can be easily removed and replaced. Each brush head can be dedicated to specific functions (cleansing, exfoliation, application) and can be independently cleaned or replaced if contamination occurs. This segmentation allows for better hygiene management while maintaining treatment efficiency, as users can swap brush heads between different treatment steps or discard contaminated ones.
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 device provides enhanced skin treatment by combining physical cleansing with targeted phototherapy and temperature benefits, improving skin health through increased collagen production, reduced inflammation, and bacterial/viral killing, while allowing for the activation of skin care ingredients and temperature-specific therapies.
Implementation Method 1
Light of different frequencies are emitted from a light source on the skin which can support production of collagen, increase blood flow, kill viruses and bacteria and reduce inflammation
Implementation Method 2
Phototherapy can also be used outside of the field of skin care to provide cleaning and sanitization benefits
Implementation Method 3
Hot and cold materials placed on the skin have also been demonstrated to have medical, cosmetic and therapeutic benefits
Implementation Method 4
Hot and cold materials placed on the skin have also been demonstrated to have medical, cosmetic and therapeutic benefits
Implementation Method 5
vibration from an electric source and sonic waves from an electrical device have been demonstrated to have medical, cosmetic and therapeutic benefits

AI summary
A handheld light treatment device that aims to provide a wide variety of uses in personal care and household cleaning. The device contains a panel with light sources positioned behind a translucent or transparent head plate, to which is attachable an applicator disc and, optionally, applicator disc attachments with selected functionalities. The light panel shines light of different frequencies that may be useful for cleaning and sanitizing various surfaces. The applicator disc and applicator disc attachments have a substantially translucent or transparent base, allowing light from the light sources to shine through the head plate as well as applicator disc and applicator disc attachment, and the applicator disc to rotate while the light panel remains fixed. The applicator disc and applicator disc attachments may have bristles or other surface elements to facilitate cleaning or other uses, and the device may dispense an ingredient.
