Solution Overview

Problem

Traditional medical displays for managing patient cardiovascular and ventilation systems, as well as medication and fluid administration, are inadequate as they do not effectively utilize human perceptual capabilities, leading to high attention demands and potential human error due to their reliance on one-sensor/one-indicator technology and lack of representation of inter-relationships between system variables.

Innovation Solution

A human-machine system employing Ecological Interface Design principles, which organizes displays into abstraction hierarchies to present goals, functional parameters, and controls, utilizing anatomical graphical representations and mass conservation principles to facilitate real-time monitoring and control of cardiovascular and ventilation systems, and medication and fluid management, thereby supporting attention allocation, situation awareness, and decision-making.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional one-sensor/one-indicator displays are used, then device complexity is reduced, but attention demands increase and human error risk increases

Engineering Contradiction:

Improvedisplay complexityVSAvoidhuman error risk

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent combines multiple sensors and indicators into an integrated display system that presents multiple system variables and their inter-relationships simultaneously. This merging approach reduces the number of separate displays clinicians must monitor while providing comprehensive system information, thereby reducing attention demands without increasing device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary processing layer that transforms raw sensor data into meaningful system state representations. This intermediary layer processes and synthesizes information from multiple sensors before presentation to the clinician, reducing the cognitive load of interpreting raw data while maintaining system reliability through structured information presentation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If traditional numeric and meter displays are used, then manufacturing precision requirements are reduced, but data transmission effectiveness to human decreases

Engineering Contradiction:

Improvedisplay manufacturing precisionVSAvoiddata transmission effectiveness

Core Design Contradiction:

Manufacturing precisionVSLoss of information

Solution Approach 1:

The patent changes the parameter of information presentation from traditional numeric/meter formats to ecological interface displays that represent system states visually. This parameter change transforms how information is encoded and presented, improving data transmission effectiveness by leveraging human perceptual capabilities to understand system states more efficiently.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If traditional displays showing raw data are used, then measurement precision is maintained, but problem-solving effort increases

Engineering Contradiction:

Improvedata measurement precisionVSAvoidproblem-solving effort

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms that automatically process raw data and present derived system states to clinicians. This feedback loop maintains measurement precision by preserving accurate sensor data while reducing problem-solving effort by automatically calculating and displaying meaningful system states, allowing clinicians to focus on decision-making rather than data processing.

Inventive Principle:

Principle #23Feedback

4Device complexity

If traditional displays with fixed information hierarchy are used, then device complexity is reduced, but adaptability to different clinical situations decreases

Engineering Contradiction:

Improvedisplay structure complexityVSAvoidadaptability to clinical goals

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic display structures that can adapt to different clinical situations and goals. The ecological interface display system dynamically reconfigures information presentation based on system state and clinical context, allowing the display to adapt to varying clinical needs without requiring complex fixed hierarchical structures for each scenario.

Inventive Principle:

Principle #15Dynamics
