Multi-Grip Tensile Tester Support Structure to Prevent Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material testing machines face issues with guide rails that restrict grip movement, leading to resistance during tensile tests and potential forward tilting of grips.
Innovation Solution
A material testing machine with three or more horizontally disposed grips, featuring a support member that allows horizontal movement and restricts vertical movement, preventing grip tilting and resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide rail is disposed below the grips to prevent forward tilting, then grip stability is improved, but resistance occurs during tensile test
Solution Approach 1:
The support function is segmented into multiple discrete support points (first support member and second support member) positioned at different locations below the grips. This segmentation allows the grips to remain stable while reducing concentrated resistance that would occur with a continuous guide rail, enabling smoother tensile testing.
2Stability of the object's composition
If a guide rail is used to restrict grip movement, then forward tilting is prevented, but device complexity increases
Solution Approach 1:
The invention extracts only the essential support function from the traditional guide rail structure. Instead of using a continuous guide rail that restricts all movements, only the necessary vertical support function is retained through discrete support members, eliminating the complex restraining structure while maintaining grip stability.
3Manufacturing precision
If conventional guide rail is used, then grip positioning is maintained, but test accuracy deteriorates due to resistance
Solution Approach 1:
By segmenting the support into discrete members rather than a continuous guide rail, the grips can maintain precise positioning while experiencing minimal resistance during movement. This segmentation eliminates the friction and binding issues that would compromise test accuracy, ensuring reliable tensile testing results.

AI summary
A material testing machine grips a specimen with three or more substantially horizontally disposed grips and applies a test force to the specimen in a centrally symmetric manner, wherein the material testing machine includes, below the grips, a support member that allows substantially horizontal movement of the grips and restricts substantially vertically downward movement thereof.
