Mask-Mounted Display Mode Switching for Firefighter Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display systems for firefighters do not address the timing of screen display when a person is wearing a mask, failing to provide appropriate timing for displaying critical information.
Innovation Solution
An information display system with display means attached to a mask and display control means that switches the displaying mode of the screen, allowing for the display of environmental information and images at appropriate times, including urgent messages, using sensors and voice recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is continuously displayed on the screen for firefighters wearing masks, then information availability is improved, but distraction and cognitive overload increase
Solution Approach 1:
The display control means switches between different display modes at periodic intervals or based on trigger events. Information is not continuously displayed but shown periodically or event-driven, reducing distraction while maintaining information availability. For example, the system may switch between showing environmental information, camera images, and urgent messages at different times or based on detected conditions.
Solution Approach 2:
The display mode is made dynamic and adaptable rather than static. The display control means adjusts the displaying mode based on situational context, firefighter actions, or environmental conditions. This dynamic switching allows the system to optimize between information provision and distraction reduction in real-time.
2Loss of information
If multiple types of information are displayed simultaneously, then information completeness is improved, but readability and focus deteriorate
Solution Approach 1:
Different types of information are segmented into separate display modes or time slots. Environmental information, camera images, and urgent messages are displayed in different modes rather than all simultaneously. This segmentation maintains information completeness while improving readability by presenting one type of information at a time.
Solution Approach 2:
Different regions or aspects of the display have different qualities optimized for their specific purpose. Urgent messages may be displayed with high visibility characteristics (bright colors, large text) in specific locations, while other information uses different display characteristics. This local optimization maintains overall information completeness while ensuring critical information remains readable and focused.
3Loss of information
If the display system provides comprehensive environmental information, then situational awareness is improved, but device complexity increases
Solution Approach 1:
The display means serves multiple functions through a single device. The same display component presents environmental information, camera images, and urgent messages by switching modes rather than requiring separate dedicated displays for each function. This multi-functionality maintains comprehensive situational awareness while reducing overall device complexity.
