Engineering Contradiction Analysis
1Measurement precision
If traditional vibration testing systems are used without sensor configuration optimization, then the development cost and development cycle are high, but the test accuracy and portability remain poor
Solution Approach 1:
The patent integrates sensor configuration optimization, data acquisition, and analysis functions into a unified testing system. The software combines multiple previously separate functions (sensor optimization, data acquisition, signal processing) into a single integrated platform, reducing system complexity while improving measurement precision through coordinated optimization of all components.
Solution Approach 2:
The system performs self-optimization of sensor configuration through embedded algorithms that automatically determine optimal sensor placement and parameters. The testing system includes self-diagnostic and self-adjustment capabilities that eliminate the need for complex manual configuration, thereby improving test accuracy without proportionally increasing device complexity.
2Ease of operation
If multiple separate software systems are used for sensor optimization and vibration testing, then sensor configuration optimization can be achieved, but the operation convenience deteriorates
Solution Approach 1:
The testing system is designed with multi-functional capabilities that allow it to perform sensor configuration optimization, data acquisition, signal processing, and analysis within a single unified software platform. This universal system eliminates the need to switch between multiple separate software applications, improving ease of operation while maintaining high measurement precision through integrated optimization algorithms.
3Adaptability or versatility
If existing testing systems are used for hydro-pneumatic suspension vehicles, then basic testing functionality is available, but the portability and cost-effectiveness are poor
Solution Approach 1:
The testing system is designed with modular and segmented architecture that allows it to be adapted to different vehicle types and testing scenarios. The system can be configured for specific applications (hydro-pneumatic suspension testing) while maintaining portability through standardized interfaces and modular components, reducing development costs through reuse of core functionality across different platforms.
