Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical testing systems for materials are limited in throughput and can only test one large sample at a time, making it difficult to conduct high-throughput, multi-parameter, cross-scale testing of complex materials, especially in the development of new materials.
Innovation Solution
A high-throughput system that allows simultaneous tension, compression, and bending tests on multiple small-sized samples using a single motor, with modular sample testing modules equipped with ball screws, displacement sensors, and force value sensors, enabling independent testing and data collection for each sample while allowing for expansion and varying physical field conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single motor is used to drive multiple sample testing modules, then productivity is improved through simultaneous testing of multiple samples, but device complexity increases due to the need for transmission devices to distribute power to multiple modules
Solution Approach 1:
The system divides the testing apparatus into multiple independent sample testing modules, each capable of testing one sample. These modules are arranged in parallel and can be driven by a single motor through transmission devices, allowing simultaneous testing of multiple samples while maintaining modular independence for ease of setup and maintenance
Solution Approach 2:
A single motor serves multiple functions by driving multiple sample testing modules simultaneously through transmission devices. This multi-functional approach allows one power source to perform the work of what would traditionally require multiple motors, improving productivity while managing complexity through universal power distribution
2Productivity
If small-sized samples are used for testing, then productivity is improved by reducing sample preparation time and enabling more tests, but measurement precision may deteriorate due to challenges in accurately measuring mechanical properties of very small samples
Solution Approach 1:
Force value sensors and displacement sensors serve as intermediary measurement devices that bridge the gap between small sample dimensions and accurate measurement requirements. These sensitive sensors can detect minute forces and displacements, enabling precise measurement of mechanical properties even for very small samples, thus maintaining measurement precision while benefiting from the productivity gains of small sample testing
3Productivity
If multiple sample testing modules are arranged in parallel, then productivity is improved through concurrent testing, but device complexity increases due to additional sensors and control systems required for each module
Solution Approach 1:
Each sample testing module is designed as an independent segment with its own force value sensor and displacement sensor. This segmentation allows multiple modules to operate concurrently for improved productivity while maintaining individual module simplicity, making the overall system easier to control and maintain despite having multiple modules
Solution Approach 2:
Each module is equipped with force value sensors and displacement sensors that provide real-time feedback on the testing process. This feedback mechanism enables precise control of each individual module while they operate in parallel, allowing the system to manage the complexity of multiple concurrent tests through automated monitoring and adjustment
