Coordinate-Space Display for Abnormality and Reliability Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of target equipment face challenges in effectively managing multiple index values such as abnormality degree and reliability degree, as the actual degree of abnormality and necessity for intervention vary with the reliability level, even when the abnormality degree is high, requiring a solution to easily check and consider these index values simultaneously.
Innovation Solution
A system comprising a data acquisition unit, a first index value calculation unit, a second index value calculation unit, and a display control unit that displays a coordinate space defined by axes representing the first and second index values, allowing operators to visualize and assess the magnitude of both values simultaneously.

Engineering Contradiction Analysis
1Loss of information
If multiple index values (abnormality degree, reliability degree) are displayed separately, then each index can be calculated and monitored, but operators cannot easily check and compare multiple index values simultaneously
Solution Approach 1:
The patent combines multiple index values (abnormality degree, reliability degree, and other operation indices) into a single coordinate space display. Each index becomes an axis, and process data is represented as representative points in this multi-dimensional space, allowing operators to view all indices simultaneously in one unified visualization rather than separate displays.
Solution Approach 2:
The patent transforms the display of multiple index values from separate one-dimensional representations into a multi-dimensional coordinate space. By adding dimensions for each index type, the system enables simultaneous visualization of multiple parameters, allowing operators to assess relationships between indices (such as abnormality degree versus reliability degree) in a single view.
2Device complexity
If only abnormality degree is displayed, then the display is simple, but operators cannot assess the actual necessity for intervention as reliability degree varies
Solution Approach 1:
The patent adds reliability degree as an additional dimension (axis) to the coordinate space, perpendicular to the abnormality degree axis. This allows the display to remain conceptually simple (still a 2D visual representation) while providing precise assessment capability, as operators can evaluate the combination of abnormality degree and reliability degree to determine actual intervention necessity.
3Loss of information
If individual index values are analyzed separately, then each index can be understood in detail, but decision-making requires considering multiple indices together which is time-consuming
Solution Approach 1:
The patent merges multiple individual index analyses into a single integrated coordinate space visualization. Operators can see all index values and their relationships simultaneously, eliminating the need to switch between separate displays or mentally integrate multiple separate assessments, thus reducing decision-making time while preserving all necessary information.
Solution Approach 2:
By organizing indices as dimensions in a coordinate space, the patent enables simultaneous visualization of multiple parameters that would otherwise require separate analysis. The spatial arrangement allows operators to quickly grasp relationships between indices (such as high abnormality with low reliability) without sequential analysis, significantly reducing decision time.
