Portable Breathing Assist Display With Flexible Remote Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional breathing assistance apparatuses have integrated displays that are often positioned too low, making it difficult for users to view therapy data and adjust settings, increasing the risk of infectious disease transmission and limiting usability due to the fixed screen orientation.
Innovation Solution
A portable display unit that can be tethered to the base unit via a flexible and retractable cable or wireless interface, allowing it to be positioned separately and at a more convenient height for user interaction, with features like a touch screen and adjustable angle for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is integrated into the base unit, then the device structure is simplified, but the display position is fixed and too low for comfortable viewing and interaction
Solution Approach 1:
The display unit is separated from the base unit and implemented as a portable, wireless display device. This segmentation allows the display to be positioned independently at an optimal viewing height while the base unit remains compact and simple in structure.
Solution Approach 2:
A wireless communication interface acts as an intermediary between the base unit and the portable display unit. This enables data transmission and control functionality without requiring a physical connection, thus maintaining structural simplicity while achieving positioning flexibility.
2Ease of operation
If the display is positioned at a higher, more visible location, then user interaction is improved, but the risk of infectious disease transmission increases due to closer proximity to the patient
Solution Approach 1:
By separating the display unit from the base unit, the system allows the display to be positioned at a higher location that is more visible to users while maintaining a greater distance from the patient's breathing zone, thus reducing infectious disease transmission risk.
Solution Approach 2:
The display positioning is moved from the horizontal plane (near the base unit) to the vertical dimension (higher elevation), allowing optimal visibility and user interaction while maintaining safe distance from the patient.
3Ease of operation
If the display has a fixed orientation, then the device structure is simpler, but the usability is limited when users need to view from different angles
Solution Approach 1:
The portable display unit incorporates an adjustable screen orientation feature that allows the display angle to be dynamically changed according to user needs. This dynamic adjustment capability improves usability while the portable nature of the device keeps the overall structure relatively simple.
