Solution Overview
Problem
Respiratory devices used in emergency situations often rely on external power sources that can fail, leading to interruptions in power supply during patient transport, posing a risk to critical-care patients who may struggle to breathe or receive necessary medication.
Innovation Solution
An uninterruptible power supply system integrated with respiratory devices that includes a battery pack, power supply circuit, and warning system to maintain continuous power, allowing for seamless operation during power outages or transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If respiratory devices are plugged into external power sources for operation, then the devices can function properly to assist patients, but the power supply may cease functioning during transport or emergencies
Solution Approach 1:
The patent applies preliminary action by incorporating a battery pack into the uninterruptible power supply system that is pre-charged and ready to immediately take over when external power fails. The battery pack is prepared in advance within the housing, with charging circuits already configured, so that no additional setup is needed during emergencies or transport when power continuity is critical.
2Reliability
If a battery pack is added to provide backup power, then uninterrupted power is achieved, but the device becomes heavier and more complex
Solution Approach 1:
The patent merges the battery pack, charging circuits, power management components, and control systems into a single integrated uninterruptible power supply unit housed in one housing. This consolidation combines multiple functions (power storage, charging, switching, and monitoring) into one compact assembly, reducing the overall weight compared to having separate battery packs and power supplies, while maintaining reliable power continuity.
3Reliability
If power supply circuit is designed to bypass battery pack, then seamless power transition is achieved, but the circuit complexity increases
Solution Approach 1:
The patent uses a controller as an intermediary that automatically manages the switching between external power and battery pack power. The controller monitors power availability and seamlessly transitions between power sources without requiring complex manual intervention or complicated circuit design, simplifying the overall system while ensuring uninterrupted power delivery to the respiratory device.
4Loss of information
If warning system is added to indicate power level, then user awareness of battery status is improved, but the device complexity increases
Solution Approach 1:
The patent implements a warning system that uses color changes in visual indicators (such as LED lights) to communicate battery power levels to users. Different colors represent different charge states, providing intuitive power level information without requiring complex displays or interfaces, thus minimizing added complexity while effectively preventing information loss about battery status.
