Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing phototherapy devices, particularly masks, pose issues such as exposure to LEDs and circuits, discomfort due to direct contact, claustrophobia, uneven light distribution, and potential skin reddening, limiting effective treatment of the entire face.
Innovation Solution
A facial mask with a frame supporting light-emitting diodes arranged along meridian and parallel lines, varying light power density to optimize light distribution, and a flexible design for comfort and safety, using translucent materials to minimize direct contact and glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional phototherapy devices use large UV-C lamps, then sterilization effectiveness is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent divides the sterilization function into multiple small UV-C LED modules instead of using a single large UV-C lamp. Each module contains multiple UV-C LEDs arranged in an array, allowing the sterilization function to be segmented into portable, lightweight units that can be easily positioned and operated while maintaining effective sterilization coverage
2Power
If phototherapy devices use high power UV-C sources, then treatment effectiveness is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines multiple low-power UV-C LEDs into a single modular array unit that functions as an integrated sterilization source. By merging multiple simple LED components into one module, the system achieves high effective power for sterilization while keeping individual component manufacturing simple and scalable
Solution Approach 2:
The UV-C LED module is designed as a universal component that can be applied to various phototherapy and sterilization applications. The modular design with standardized mounting and electrical connections allows the same module to be used in different device configurations, simplifying manufacturing across product lines
3Reliability
If UV-C lamps are used for sterilization, then sterilization capability is improved, but device portability and flexibility deteriorate
Solution Approach 1:
The sterilization system is segmented into multiple independent UV-C LED modules that can be individually positioned and configured. Each module operates as a separate functional unit, allowing flexible arrangement to adapt to different sterilization scenarios and device form factors while maintaining effective UV-C coverage
Solution Approach 2:
The patent employs controllable UV-C LED modules that can be dynamically activated or deactivated based on operational requirements. The modular design allows flexible positioning and orientation of active modules to adapt to different treatment areas and configurations, providing dynamic adaptability while maintaining sterilization capability

AI summary
The invention relates to a face mask (10) which comprises a frame (12) defining a front face directed towards a user's face and an opposite back face, the frame (12) supporting a plurality of light-emitting light points arranged in the mask (10) in order to produce energetic illumination of the user's face through the front face. According to the invention, the face mask (10) defines, so as to correspond to the face, at least one remarkable line referred to as the meridian line from the forehead to the chin and a plurality of remarkable lines referred to as parallel lines extending between each side of the face substantially transversely to the meridian line, and the light points are arranged substantially along the parallel lines in order to produce a spatial distribution of the energetic illumination of the face having maximum light power density along these lines.
