Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for medical diagnostics struggle to efficiently display both the current state and historical trends of measurement data on a variety of displays, often requiring compromises between detail and compression, which affects readability and memory usage.
Innovation Solution
A method for processing measurement signals that calculates display state parameters based on current and previous measurement data, using a combination of display regions and parameters like brightness and color intensity, to efficiently illustrate current states and trends while conserving memory and display space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the full history of measurements is displayed in detail, then the completeness of measurement history is improved, but the display space and memory requirements increase
Solution Approach 1:
The display is divided into multiple display regions, each representing a specific time window or measurement category. This segmentation allows the system to organize measurement history into manageable segments that can be displayed efficiently without requiring excessive display space, while still preserving the complete measurement history across all regions.
Solution Approach 2:
The patent transitions from displaying measurements in a single linear sequence to a multi-dimensional display structure with multiple regions representing different time windows or measurement types. This dimensional transformation enables comprehensive measurement history to be presented in a compact spatial arrangement that fits various display formats.
2Area of stationary object
If measurement data is compressed to save display space, then the display space efficiency is improved, but the readability and detail of measurement trends deteriorate
Solution Approach 1:
Different display regions are allocated with different levels of detail and compression based on their specific purpose. Recent measurements or critical time windows may be displayed with higher resolution and less compression, while older or less critical measurements use greater compression. This local quality differentiation maintains trend readability in important areas while optimizing overall display space efficiency.
3Measurement precision
If the display shows detailed measurement snapshots, then the current state identification is improved, but the trend detection over time is worsened
Solution Approach 1:
The patent merges multiple measurement snapshots across different time windows and display regions to create a comprehensive view that simultaneously preserves current state details and historical trends. By combining information from multiple regions representing different time periods, the system enables users to identify current states with precision while also detecting trends through the aggregated temporal pattern.
Solution Approach 2:
The display system provides feedback by showing how current measurements relate to historical patterns across multiple regions. This feedback mechanism helps users understand both the precise current state and its context within broader trends, as the multi-region display reveals temporal patterns that connect current readings to historical behavior.
4Adaptability or versatility
If different display formats are supported, then the adaptability to various devices is improved, but the complexity of the display system increases
Solution Approach 1:
The multi-region display structure serves multiple functions simultaneously: it adapts to different display formats and sizes, preserves complete measurement history, enables trend detection, and maintains current state visibility. This universal structure can be configured for various device types (smartphones, tablets, desktops, medical devices) without requiring fundamentally different display approaches, thereby reducing overall system complexity despite supporting diverse formats.
