Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material testing machines are designed for a single load case, limiting their ability to perform a variety of tests and are not durable enough to handle the high forces involved in material testing.
Innovation Solution
A material testing apparatus with a specimen holder, rod arrangement, and electromechanical actuator that allows for adjustable speeds between 0 m/s to 12 m/s, enabling multiple load cases including tensile, compressive, and impact tests, with features like detachable clamping, magnet fixation, and a horizontal impact direction to minimize gravitational interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If testing machines are designed for one specific load case, then sufficient testing performance for that load case is achieved, but the machine cannot perform other types of tests
Solution Approach 1:
The testing machine is designed with a universal rod arrangement that can perform multiple load cases including tensile testing, compressive testing, impact testing, and bending flexural testing. The rod arrangement serves as a multi-functional component that replaces multiple specialized testing machines, enabling one machine to perform various tests by adjusting the rod's position and configuration
2Force
If high forces are applied during material testing, then sufficient testing performance is achieved, but durability and vibration safety are compromised
Solution Approach 1:
The rod arrangement is designed with counterbalancing mechanisms that compensate for the high forces applied during testing. By implementing force distribution and counterweight systems, the machine can handle high mechanical loads while reducing the stress on individual components, thereby improving durability and vibration safety
3Force
If high forces are applied during material testing, then sufficient testing performance is achieved, but vibration safety is compromised
Solution Approach 1:
The machine incorporates vibration damping and shock absorption systems that are pre-installed to cushion against the harmful vibrations generated during high-force testing. These protective mechanisms are built into the rod arrangement and support structures to mitigate vibration effects before they can cause damage

AI summary
An apparatus for material testing of a specimen, in particular a battery device. The apparatus includes a specimen holder arrangement with a specimen holder for holding a specimen to be tested, a rod arrangement for moving in direction to the specimen holder for transmitting a mechanical load to the specimen, and an electromechanical actuator for moving at least one of the rod arrangement and the specimen holder arrangement with respect to each other along a longitudinal impact direction. The electromechanical actuator arrangement is configured to adjust the speed to any speed between 0 m/s to 12 m/s between the rod arrangement and the specimen holder arrangement other for transmitting a mechanical load to the specimen.
