Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical monitoring systems lack flexibility and capability to provide additional information beyond pre-defined parameters, limiting medical personnel's ability to derive and monitor custom biometric parameters, which restricts their ability to respond effectively to patient conditions.
Innovation Solution
A medical monitoring system that includes biometric monitors, an expression evaluator, and further processing components to generate and process user-defined biometric parameters from monitored parameters, allowing medical personnel to create and analyze custom parameters using user-defined expressions and pre-defined functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If medical monitoring systems provide only pre-defined monitored parameters, then the system complexity is reduced and ease of operation is improved, but the adaptability and versatility of the monitoring system deteriorates
Solution Approach 1:
The monitoring system is designed to perform multiple functions: it can monitor both pre-defined parameters and user-defined parameters, evaluate user-defined expressions, and process various types of biometric data through a unified architecture. This multi-functionality allows the system to adapt to different monitoring needs without requiring separate specialized systems.
Solution Approach 2:
An expression evaluator component is introduced as an intermediary between data collection and data processing. This mediator evaluates user-defined expressions and generates additional biometric parameters, enabling flexible monitoring capabilities without directly complicating the core monitoring architecture. The expression evaluator acts as a buffer that handles customization while maintaining system stability.
2Loss of information
If medical personnel perform manual calculations and estimations using existing monitoring data, then additional information can be derived, but the loss of time and productivity deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically evaluating user-defined expressions and generating additional biometric parameters in real-time, before medical personnel would need to manually calculate them. This eliminates the need for manual calculations and ensures that all required information is immediately available for clinical decision-making.
Solution Approach 2:
The monitoring system serves itself by automatically processing monitoring data through user-defined expressions and generating derived parameters without requiring external manual intervention. The system self-manages the calculation and estimation processes that would otherwise require medical personnel's time and expertise.
3Adaptability or versatility
If the system processes user-defined biometric parameters differently from monitored biometric parameters, then customization is improved, but the device complexity and ease of operation worsen
Solution Approach 1:
The further processing component is designed to handle both monitored biometric parameters and user-defined biometric parameters through the same processing pipeline. This universal processing approach maintains operational simplicity while accommodating parameter customization, as the system treats both types of parameters uniformly despite their different origins.
Data Source
AI summary
In a medical monitoring system, one or more biometric monitors collect data of a plurality of monitored biometric parameters. An expression evaluator evaluates a user-defined expression incorporating one or more of the monitored biometric parameters to generate data for a user-defined biometric parameter. A further processing component performs processing and display of data of at least one parameter selected from the monitored biometric parameters and the user-defined biometric parameter. The further processing component operates in the same way regardless of whether the at least one parameter is selected from the monitored biometric parameters or the user-defined biometric parameter.
