Ventilator Removable Display Segmentation for Power and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic graphical user interfaces (GUIs) in devices like medical ventilators rely on large, power-consuming displays for both control and monitoring, leading to issues such as display failure affecting operability, high power consumption, and the need for continuous power for status information, which can hinder device functionality and battery life.
Innovation Solution
A ventilator system with a removable primary display and a system status display (SSD) that provides limited, independent status information, allowing the SSD to remain operational even when the primary display is powered down or removed, using a low-power LCD display and separate power control to conserve energy and maintain system status visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large electronic GUI display is used for control and monitoring, then information display capability is improved, but power consumption increases
Solution Approach 1:
The display system is segmented into two independent parts: a primary electronic GUI display for control and a secondary system status display for monitoring. The secondary display uses a low-power LCD technology and can operate independently when the primary display is powered down, allowing information monitoring without continuous high power consumption.
Solution Approach 2:
The monitoring function is extracted from the primary electronic display and assigned to a separate secondary display system. This extraction allows the primary display to be powered down while monitoring continues through the secondary display, reducing overall power consumption while maintaining information availability.
2Reliability
If the primary display is always on for monitoring, then operational visibility is improved, but battery life decreases
Solution Approach 1:
The display system is divided into primary and secondary independent displays. The secondary display is specifically designed to provide essential status information with minimal power consumption, enabling the primary display to enter low-power or off states while maintaining operational monitoring capability through the secondary display.
Solution Approach 2:
The system changes the power state parameter of the displays dynamically. The secondary display operates at a lower power level and can remain active while the primary display is powered down, altering the power consumption parameter without sacrificing operational visibility.
3Ease of operation
If the primary display is removed for transport, then portability is improved, but status monitoring capability deteriorates
Solution Approach 1:
The monitoring function is extracted from the removable primary display and embedded in the secondary display that remains with the device. This ensures that status monitoring capability is retained even when the primary display is removed for transport or other purposes.
Solution Approach 2:
The secondary display is built into the device beforehand as a backup monitoring system. This prior cushioning ensures that if the primary display is removed or fails, the device can still provide status information, preventing loss of monitoring capability.
