Breathing Apparatus Graphical Interface Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Breathing apparatuses are challenging to control intuitively, leading to potential incorrect settings that can negatively impact patient safety, especially in anesthesia, due to complex and time-consuming adjustment processes.
Innovation Solution
A breathing apparatus with a graphical user interface and control unit that displays values on axes, allowing users to set input values by selecting portions of the interface, reducing the risk of incorrect settings through intuitive control and visual feedback, including sub-areas for preferred and non-preferred operational settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional control interfaces with multiple separate controls are used, then precise control of individual parameters is achievable, but the complexity of operation increases and intuitive control becomes difficult
Solution Approach 1:
The patent merges multiple independent control parameters (first input value and second input value) into a single graphical area where both parameters can be adjusted simultaneously through one selection action, rather than requiring separate controls for each parameter
Solution Approach 2:
The patent transforms the control interface from a one-dimensional linear arrangement of separate controls to a two-dimensional graphical area where the position within the area simultaneously encodes both input values, adding a spatial dimension to the control mechanism
2Productivity
If multiple separate controls are used for adjusting parameters, then individual parameter control is precise, but the time required for adjustment increases
Solution Approach 1:
The patent combines the adjustment of multiple parameters into a single graphical selection operation, allowing the user to set both the first and second input values simultaneously through one interaction rather than sequentially adjusting each parameter separately
Solution Approach 2:
The graphical interface pre-organizes the relationship between parameters in visual space, allowing users to directly select desired parameter combinations without needing to understand the complex interrelationships between parameters
3Reliability
If complex control interfaces are used to provide comprehensive control options, then functionality is enhanced, but the risk of incorrect settings increases
Solution Approach 1:
The graphical user interface provides visual feedback by displaying the relationship between the first and second input values in the graphical area, allowing users to see the effect of their selections and confirm correct settings before applying them
Solution Approach 2:
The patent uses different sub-areas within the graphical area to visually distinguish between preferred and non-preferred operational settings, helping users avoid incorrect configurations through visual cues rather than complex warnings or restrictions
