Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for displaying physiological information, such as cardiotocography, produce large amounts of paper that are costly and difficult to manage, and digital viewers often struggle with analyzing the vast amount of data effectively.
Innovation Solution
A system and method for displaying waveform information using a user interface with a virtual graph that plots physiological signals over time, allowing for a digital representation similar to paper strip charts, with shifting time and signal indicators to mimic the movement of paper, enabling efficient analysis and storage of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional paper strip chart systems are used to display physiological information, then the ease of review and analysis is maintained, but the quantity of paper produced increases significantly, leading to higher costs and difficulty in management
Solution Approach 1:
The patent creates a virtual copy of the traditional paper strip chart display using digital technology. The waveform module generates a digital representation of physiological signals that replicates the appearance and functionality of paper strip charts, allowing users to review and analyze data without producing physical paper. This digital copy maintains the familiar interface while eliminating the need for continuous paper consumption.
2Quantity of substance
If digital viewers are used to eliminate paper production, then paper costs and management difficulty are reduced, but the ability to analyze information effectively deteriorates
Solution Approach 1:
The virtual graph is divided into multiple segments that can be independently navigated and analyzed. The system allows users to scroll through historical data, pause at specific time points, and examine waveform details closely. This segmentation enables effective analysis of large datasets by breaking them into manageable portions while maintaining the digital advantage of reduced paper usage.
3Ease of operation
If a virtual graph with shifting indicators is used to display waveform information, then the digital display maintains the appearance and functionality of paper strip charts, but the device complexity increases
Solution Approach 1:
The virtual graph incorporates dynamic elements that move and shift to simulate the appearance of paper strip chart movement. The graph indicators and gridlines shift horizontally to represent the passage of time and the continuous display of new data, creating an immersive experience that familiar users of paper charts will recognize and find easy to operate.

AI summary
A system for displaying physiological information. The system includes a graph module that is configured to provide a two-dimensional virtual graph having a time dimension and a signal dimension. The virtual graph includes time indicators that are spaced along the time dimension and signal indicators that are spaced along the signal dimension. The system also includes a waveform module that is configured to obtain physiological signals as a function of time. The waveform module is configured to plot a waveform based upon the physiological signals onto the virtual graph. A user interface is configured to display the waveform and the virtual graph in a viewable area. The time and signal indicators of the virtual graph shift along the time dimension at a recording speed as the waveform is plotted. The plotted waveform has a fixed relationship with respect to the time and signal indicators and shifts at the recording speed.
