Respiratory Device Wireless Communication Hub
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern respiratory devices for first responders are limited by their ability to communicate with only one audio device at a time and require separate power sources for each accessory, which can be bulky and vulnerable to extreme temperatures.
Innovation Solution
A respiratory device with a rechargeable power source and universal expansion port that allows simultaneous wireless communication with multiple devices and powers multiple interchangeable electronic components, including a display and thermal imaging camera, using a transformer for voltage regulation and shielding the power source from extreme temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a respiratory device is configured to communicate with only one audio device at a time, then the device maintains simple communication protocols, but the user's communication range and networking capabilities are limited
Solution Approach 1:
The respiratory device is equipped with a universal communication interface that can simultaneously connect to multiple audio devices (headsets, smartphones, tablets, computers) through different communication protocols (Bluetooth, Wi-Fi, DECT). This allows the device to function as a multi-functional communication hub, enabling users to network with multiple devices at once while maintaining manageable protocol handling through automated protocol selection and management software.
2Reliability
If each accessory (in-mask display, thermal imaging camera) has its own power source, then each accessory can operate independently, but the overall bulk of the respiratory device increases
Solution Approach 1:
The respiratory device incorporates a single centralized rechargeable power source that electrically connects to and powers all accessories (in-mask display, thermal imaging camera, communication modules). This consolidated power approach reduces the total volume compared to multiple separate batteries, while maintaining reliable power supply to all components through a unified electrical distribution system within the device architecture.
3Reliability
If each accessory has its own power source, then each accessory can be independently powered, but the power sources are not shielded from extreme temperatures which could result in battery failure or explosion
Solution Approach 1:
By consolidating all power sources into a single centralized rechargeable battery unit, the device creates one protected compartment that can be thermally managed and shielded from extreme temperatures. This unified approach allows for better thermal protection strategies (insulation, temperature monitoring, controlled ventilation) compared to multiple exposed batteries, while still providing independent power to all accessories through internal electrical connections.
4Use of energy by moving object
If multiple accessories are powered by separate power sources, then each accessory has dedicated power, but the device requires multiple charging operations and power management
Solution Approach 1:
The centralized power source is integrated with a unified power management system that automatically distributes electrical energy to all connected accessories based on their power requirements. This single charging interface and centralized control eliminates the need for multiple charging operations, while the power management system handles load balancing and energy distribution to maintain dedicated power supply to each accessory through intelligent electrical routing.
