Ventilator Touchscreen Interface for Faster Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ventilators often have complex operation with unintuitive menu navigation, requiring users to navigate through deep, nested menu structures for setting adjustments.
Innovation Solution
An operating device for a ventilator featuring a touch-sensitive graphic display and a single mechanical control element, allowing for intuitive setting adjustments by touching the display to select values and confirming with a mechanical button, with the device storing and applying settings directly to ventilation parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate operating elements and displays are used for ventilator controls, then the device can provide comprehensive control functions, but the operation becomes complex with unintuitive menu navigation
Solution Approach 1:
The patent merges separate operating elements and displays into a unified touch-sensitive graphic display where the entire display surface serves as the control interface. Users directly touch parameter representations on the display to adjust settings, eliminating the need for separate physical controls and complex menu navigation while maintaining comprehensive ventilator control functions.
2Adaptability or versatility
If deep nested menu structures are used for parameter adjustment, then comprehensive control options are available, but the time required for setting adjustments increases
Solution Approach 1:
The patent extracts parameters from deep nested menu structures and presents them directly on the main display screen. Each ventilator parameter is represented as a touchable graphic element accessible on the main interface, allowing users to adjust settings immediately without navigating through multiple menu levels, thus reducing setting adjustment time while maintaining comprehensive parameter control.
3Ease of operation
If multiple control elements are provided for ventilator operation, then precise control is achievable, but the device complexity increases
Solution Approach 1:
The patent implements a universal touch-sensitive graphic display that performs multiple control functions simultaneously. The display shows ventilator parameters, accepts user input through direct touching of parameter representations, provides visual feedback, and maintains settings in memory - replacing multiple specialized control elements with a single multi-functional interface that achieves precise control without increasing device complexity.
