Material Test Display Layout for Load and Displacement History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display methods for material testing machines fail to clearly distinguish between the time-series transitions of test force and displacement, requiring users to switch between screens and making it difficult to understand the measurement history of the load applied to a test piece and the change in the test piece.
Innovation Solution
A test apparatus and method that displays the load measurement history and change measurement history on a single screen, with distinct areas for load and change measurements, using images and graphs to clearly indicate the current values and transitions, facilitating easy understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the current measured value is displayed on a single display, then the display is simple, but the time-series transition of the measured value cannot be grasped
Solution Approach 1:
The display screen is segmented into multiple functional areas: a current value display area showing the latest measured value, and a time-series graph area showing the transition over time. This segmentation allows users to simultaneously access both the current state and historical trend without switching screens, resolving the contradiction between display simplicity and ease of grasping time-series data.
2Ease of operation
If the time-series transition graph of test force and displacement are displayed superimposed on a common time axis, then both parameters are shown on one screen, but it is difficult to distinguish which graph indicates test force and which indicates displacement
Solution Approach 1:
Different visual qualities are applied to different graph areas: the test force graph area and the displacement graph area are differentiated through distinct visual characteristics such as different color tones, line styles, or background patterns. This local quality differentiation allows users to easily distinguish between the two parameters while maintaining both on a single screen, preventing information confusion.
3Ease of operation
If only the current measured value is displayed on the screen, then the display is simple, but the measurement history cannot be displayed
Solution Approach 1:
The display utilizes the time dimension by presenting measurement history as a time-series graph where the horizontal axis represents time and the vertical axis represents the measured value. This dimensional approach allows the measurement history to be visualized efficiently without consuming excessive screen area, as the data is compressed along the time dimension rather than requiring separate detailed views for each measurement point.

AI summary
A test apparatus includes a display controller. The display controller displays a load measurement value image indicating a measured value of a load measured by a load measurement unit at a predetermined measurement time point, a load measurement graph image showing a time-series transition of the load measured by the load measurement unit during a predetermined measurement period including the predetermined measurement time point, and a load measurement label image, in a first area of a test monitor screen. The display controller also displays a change measurement value image indicating a measured value of a change measured by a change measurement unit at the predetermined measurement time point, a change measurement graph image showing a time-series transition of the change measured by the change measurement unit during the predetermined measurement period, and a change measurement label image, in a second area different from the first area.
