Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material test machines using strain rate control face challenges in confirming the progress of tensile tests, making it difficult to ensure worker safety when the test piece breaks during the test.
Innovation Solution
A material test machine equipped with a detection unit to measure strain, a calculation unit to determine strain rate, and a display control unit to visualize the strain rate changes, allowing for easy monitoring of the test progress through graphical representations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strain rate control is implemented in material test machines, then the material test can be executed with controlled deformation rate, but it becomes difficult to confirm the progress of the test and ensure worker safety
Solution Approach 1:
The patent implements a feedback mechanism by displaying the calculated strain rate on a display device. The control unit receives strain amount data from the detection unit, calculates strain rate, and feeds back this information visually to the operator. This allows real-time monitoring of test progress while maintaining strain rate control, resolving the contradiction between control reliability and test progress visibility.
2Ease of operation
If manual assessment of test progress is required, then worker safety can be monitored, but the complexity of operation increases and safety confirmation becomes difficult
Solution Approach 1:
The system performs self-service by automatically calculating and displaying strain rate information without requiring manual intervention. The detection unit automatically detects strain amount, the control unit calculates strain rate, and the display device shows the results. This automated self-monitoring improves both ease of operation and safety confirmation reliability, as the system continuously tracks and displays test progress without operator burden.

AI summary
A tensile test machine is a tensile test machine that executes a tensile test by applying a test force to a test target to deform the test target and includes a detection unit that detects an elongation amount of the test target, a calculation unit that calculates an elongation rate of the test target on the basis of a detection result of the detection unit, and a display control unit that displays a graph showing a change in the elongation rate.
