Display Control Unit for Medical Inspection Trend Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical examination techniques fail to accurately determine whether inspection results are abnormal or normal, particularly when the last result is borderline, making it difficult for examiners to support appropriate diagnosis.
Innovation Solution
A display control device and method that displays a graph of inspection results over time, using different colors or densities based on frequency, to help identify abnormal values and trends, allowing for better visualization of inspection history and supporting examiner diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only the last inspection result is displayed, then the display is simple, but it is difficult to determine whether the result is abnormal occasionally or shows a strong tendency
Solution Approach 1:
The patent transitions from displaying only the last inspection result (one-point display) to displaying a time series of multiple inspection results (multi-point display along time axis). This dimensional expansion from single point to temporal sequence enables examinationers to distinguish between occasional abnormalities and consistent trends, resolving the contradiction between display simplicity and diagnostic accuracy.
Solution Approach 2:
The patent performs preliminary display of multiple previous inspection results before the last result, allowing examinationers to pre-assess trends and patterns. By showing the temporal context in advance, the system enables better judgment of whether an abnormal result is isolated or part of a continuing pattern, improving measurement precision without significantly complicating the display interface.
2Measurement precision
If multiple previous inspection results are displayed, then the ability to determine abnormal trends is improved, but the display complexity increases
Solution Approach 1:
The patent segments the display into distinct visual elements: the last inspection result is highlighted separately, while previous results are displayed as a time series sequence. This segmentation allows the system to present multiple data points (improving abnormality determination) while maintaining clear visual hierarchy and avoiding overwhelming complexity through organized presentation.
Solution Approach 2:
The patent employs color coding to distinguish between normal and abnormal inspection results, with abnormal values highlighted in different colors. This visual differentiation enables examinationers to quickly identify trends and abnormalities without needing to analyze every data point in detail, thus improving measurement precision while keeping the display interface manageable and not overly complex.
3Ease of operation
If inspection results are displayed without frequency information, then the display is simple, but it is difficult to identify patterns and trends
Solution Approach 1:
The patent creates a visual copy or representation of the frequency distribution pattern alongside the time series display. By incorporating frequency information as an additional visual layer (such as density indicators or frequency charts), the system preserves pattern information that would otherwise be lost, enabling examinationers to identify trends without significantly increasing display complexity.

AI summary
A display control device includes: a display control unit that displays a graph representing a history of inspection results including a last inspection result of a subject individual and a predetermined number of previous inspection results from the last inspection result for a predetermined inspection item among plural inspection items in the subject, the graph having a first axis representing the inspection results and a second axis representing a time series, and performs control for displaying information representing plural inspection results of at least one of the subject individual or the same variety as a variety of the subject individual on a position corresponding to a specific point of time of the second axis along a direction of the first axis with a different color or density according to a frequency of each inspection result.
