Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrity testing devices face difficulties in clearly displaying and analyzing multiple vibration data results, particularly when using contour graphs or three-dimensional line graphs, making it hard to determine trends over time.
Innovation Solution
A display device that shows a first two-dimensional display of frequency and spectral intensity of vibration, with measurement values and composite values displayed successively, including intermediate values generated between measurement times, allowing for easier analysis and visualization of vibration data.

Engineering Contradiction Analysis
1Loss of information
If multiple vibration data results are simultaneously displayed in contour graphs or three-dimensional line graphs, then comprehensive analysis information is provided, but the results become difficult to determine and analyze, making trend determination hard
Solution Approach 1:
The patent segments multiple vibration measurement results into separate two-dimensional displays, each showing one measurement value or composite value over time. This segmentation allows each result to be clearly visible and analyzable individually, while still providing comprehensive information through multiple separate views rather than one cluttered combined view.
Solution Approach 2:
The patent transitions from three-dimensional line graphs to multiple two-dimensional displays arranged in a temporal sequence. By adding the time dimension as a sequential arrangement of 2D displays rather than crowding multiple 3D graphs in space, the system maintains comprehensive information while improving clarity and ease of analysis.
2Reliability
If measurement values are displayed continuously over time, then vibration trends can be determined, but the display complexity increases
Solution Approach 1:
The patent segments the continuous time display into discrete time periods, with each display showing measurement values for a specific time period. This segmentation reduces display complexity by breaking down the continuous data stream into manageable segments while still enabling trend determination through sequential comparison of the segments.
Solution Approach 2:
The patent generates intermediate values between measured values in advance by dividing time periods and calculating intermediate points. This preliminary calculation allows for smoother trend visualization without requiring complex real-time processing, as the intermediate data points are pre-computed and ready for display.

AI summary
An inertial measurement system includes three acceleration sensors detecting along three orthogonal axes, a display having several display areas, and a processor programed to perform a process. The processor calculates frequencies and spectral intensities of vibrations based on detected time series accelerations by three acceleration sensors and obtains relationship values between the calculated frequencies and the calculated spectral intensities. The processor causes the display to successively display an N-th value, intermediate values, and an (N+1)-th value of the relationship values at one display area in time series.
