Solution Overview

Problem

Current medical device displays often lead to visual misinterpretation and confusion due to slow updates and unsuitable representations of multiple values, particularly in emergency situations like resuscitation and ventilation, where clear and quick visualization of critical parameters is essential.

Innovation Solution

A tachometer-like display is implemented in medical devices, such as defibrillators and ventilators, to provide a clear and intuitive output of parameters and measured values, with color-coded limits, numerical values, and trend plots, allowing for easy reading of vital information during emergencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional displays are used to show multiple parameters and measured values, then comprehensive information can be provided, but visual misinterpretation and confusion occur due to slow updates and unsuitable representations

Engineering Contradiction:
Improveinformation clarityVSAvoidupdate speed
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The display is segmented into multiple independent gauge elements, each dedicated to displaying a specific parameter or measured value. This segmentation allows each parameter to be visualized independently with its own optimal representation format, preventing visual confusion while maintaining comprehensive information display. Each gauge can update at its own optimal rate without affecting others.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional two-dimensional tabular or numerical displays to a multi-dimensional gauge visualization system. Each parameter is represented with multiple visual dimensions including needle position, color coding, scale ranges, and graphical indicators, enabling faster comprehension of parameter states and trends simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If multiple parameters are displayed simultaneously in traditional formats, then complete monitoring is achieved, but optical confusion occurs between several displayed values

Engineering Contradiction:
Improvereading accuracyVSAvoiddisplay structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Each gauge element is designed with local quality optimization tailored to its specific parameter type. Different gauges can use different scale types (linear, logarithmic, categorical), color schemes, and visual indicators appropriate for their specific measurement, ensuring optimal readability for each parameter while maintaining a unified overall display structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The display system employs color changes and color coding to differentiate between various parameters and their states. Each gauge can use color to indicate parameter ranges (normal, warning, critical), trends, or parameter types, enabling rapid visual discrimination between multiple displayed values without increasing structural complexity.

Inventive Principle:
Principle #32Color changes

3Measurement precision

If detailed numerical values are displayed for all parameters, then precision is maintained, but quick visualization of critical information is hindered

Engineering Contradiction:
Improveparameter accuracyVSAvoidinformation processing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The gauge needles provide continuous visual feedback through their position and movement, creating a dynamic visual representation that updates instantly as parameters change. This mechanical-like movement of needles across scales provides immediate visual detection of parameter changes without requiring detailed numerical processing, maintaining precision while enabling rapid information processing.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

Each gauge provides immediate visual feedback through needle position, color indicators, and scale markings that continuously reflect current parameter values. This feedback mechanism allows operators to quickly assess parameter states and trends without mentally processing detailed numerical data, maintaining measurement precision while dramatically improving information processing speed.

Inventive Principle:
Principle #23Feedback
