Solution Overview
Problem
Existing material testing equipment cannot accurately evaluate mechanical properties under complex load conditions and fails to simulate multi-physical field effects such as temperature, electric, and magnetic fields, limiting its application to novel functional materials.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional offsite testing methods are used, then macromechanical properties can be tested, but real-time dynamic observation of microstructural profiles cannot be obtained
Solution Approach 1:
The patent combines the testing system with an in-situ observation module that includes optical microscopy, scanning electron microscopy, and atomic force microscopy capabilities. This merging allows simultaneous mechanical testing and microstructural observation, enabling real-time dynamic observation of microstructural profiles during loading without requiring separate offsite testing facilities.
Solution Approach 2:
The testing system is designed with multi-functionality to perform both mechanical property testing and microstructural observation. The in-situ observation module can switch between different microscopy modes (optical, scanning electron, atomic force) to observe microstructural changes under various loading conditions, making the system universally applicable for both macromechanical and microstructural analysis.
2Measurement precision
If single load testing is performed, then testing simplicity is maintained, but accurate evaluation of material under complex load cannot be achieved
Solution Approach 1:
The patent implements a dynamic loading system that can apply multiple types of loads (tension, compression, bending, torsion, fatigue) simultaneously or sequentially. The system uses programmable control to dynamically adjust loading parameters, enabling simulation of complex multi-load conditions that accurately reflect real-world material behavior while maintaining measurement precision through coordinated control of multiple actuators.
3Adaptability or versatility
If multifunctional material testing machine is used, then complex load can be applied, but certain load types cannot be separately or successively applied
Solution Approach 1:
The testing system is segmented into independent loading modules, each capable of applying specific load types (tension, compression, bending, torsion, fatigue). This segmentation allows any combination of loads to be applied separately or successively by activating individual modules, providing both complex load capability and operational flexibility. The modular design enables precise control over the sequence and combination of loads applied to the test specimen.
