Solution Overview
Problem
Conventional wearable air purification systems often obscure facial features, making communication challenging and are bulky, which limits their practicality for daily wear.
Innovation Solution
A wearable air purification system with a head-mounted support and an air delivery mask featuring a directional illumination source that illuminates the mouth region, combined with audio earpieces for enhanced functionality and visual appeal, allowing for clear communication while maintaining air purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tight-fitting mask is worn to provide comprehensive filtering functionality, then air purification effectiveness is improved, but facial features are obscured and communication becomes challenging
Solution Approach 1:
The patent introduces an illumination source as an intermediary element that illuminates the user's face through the mask, enabling clear communication while maintaining the mask's protective function. The light acts as a mediator between the obscured face and the external environment, allowing others to see the user's facial expressions and mouth movements.
Solution Approach 2:
The illumination source emits light that changes the visual appearance of the mask and user's face. By introducing controlled illumination, the system transforms the opaque, obscuring mask into a visually informative device that displays facial features and expressions, thereby improving communication without compromising air purification.
2Reliability
If a bar-like mask or visor is used to deliver filtered air, then air purification functionality is improved, but the device becomes bulky and limits practicality for daily wear
Solution Approach 1:
The patent merges multiple functions into the mask structure: air delivery, illumination, and visual appeal. By combining the air delivery mask with an integrated illumination source and sleek design elements, the system reduces perceived bulkiness while maintaining air purification functionality. The mask becomes a multi-functional device that is both practical and aesthetically pleasing.
Solution Approach 2:
The mask is designed to serve multiple purposes: delivering filtered air, providing illumination for communication, and enhancing visual appeal. This multi-functionality allows the device to be more than just a protective mask, making it suitable for daily wear while maintaining air purification effectiveness.
3Reliability
If conventional fabric masks are worn to protect against airborne pollutants, then air purification is provided, but facial features are obscured making conversation difficult
Solution Approach 1:
The illumination source serves as an intermediary that allows facial features to be seen through the mask. By introducing light as a mediating element, the system enables information transfer (facial expressions, mouth movements) while the mask continues to provide air protection, thus reducing the loss of information.
Solution Approach 2:
The illumination system changes the optical properties of the mask by introducing controlled light emission. This allows the mask to transition from an opaque barrier to a visually informative device that displays facial features and expressions, thereby reducing the information loss about the user's face during conversation.
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 system provides effective air purification while keeping the user's face visible for better communication and is designed to be more aesthetically pleasing and practical for daily use, addressing the limitations of conventional masks.
Implementation Method 1
The air delivery mask comprises an illumination source configured to illuminate the air delivery region
Data Source
AI summary
A wearable air purification system including a wearable support configured to be supported on or around a head region of a user, and an air delivery mask connected to the wearable support which is shaped to bound an air delivery region and to deliver a flow of air to the air delivery region. The air delivery mask includes an illumination source configured to illuminate the air delivery region, wherein the illumination source is directional and is oriented to target the air delivery region. The system or ‘air purifier’ is configured to direct light to the area occupied by the user's mouth when the air purifier is worn, as well as in some examples providing illumination to a mask or visor of the product itself. Examples herein are more visually appealing but the form of illumination means that the user's face is more visible to others which reduces facial features being obscured.
