Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional prestressed anchor bolt systems are used, then the structure is simple and easy to manufacture, but the system cannot adapt to large deformation in rock masses, leading to fractures and instability
Solution Approach 1:
The patent introduces a dynamic testing system that can control and measure large deformations in real-time. The testing machine incorporates movable components and control systems that adapt to varying deformation conditions, allowing the system to transition from static to dynamic operation modes to match the actual rock mass behavior during mining activities.
Solution Approach 2:
The testing system enables variation of key parameters such as deformation magnitude, loading rate, and stress conditions to simulate different rock mass scenarios. By changing these parameters, the system can evaluate anchor bolt performance under diverse large deformation conditions, enhancing adaptability without requiring multiple specialized systems.
2Measurement precision
If accurate testing of constant-resistance and large-deformation anchor shanks is performed, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent incorporates electronic sensing and control systems that replace purely mechanical measurement methods. Sensors and digital measurement devices are integrated into the testing machine to accurately capture force, displacement, and deformation data, providing precise measurement of anchor shank mechanical properties while reducing the need for complex mechanical linkages.
Solution Approach 2:
The testing system uses intermediate components such as sensors, transducers, and control units that mediate between the mechanical testing process and the measurement/analysis systems. These intermediaries enable accurate data acquisition and processing without requiring direct complex mechanical coupling, simplifying the overall system architecture while maintaining measurement precision.
3Reliability
If comprehensive testing of force, displacement, and time parameters is conducted, then the reliability of experimental data is improved, but the testing time and complexity increase
Solution Approach 1:
The testing machine is designed to continuously measure and record force, displacement, and time parameters throughout the entire testing process without interruption. The integrated control system maintains continuous data acquisition, ensuring that all relevant mechanical properties are captured in a single uninterrupted test, thereby improving data reliability while minimizing total testing time compared to multiple separate tests.
Solution Approach 2:
The testing system is designed as a multi-functional apparatus that can simultaneously measure multiple parameters (force, displacement, time) and test different types of anchor shanks under various conditions. This universal design allows comprehensive mechanical property evaluation to be performed in a single integrated testing operation, reducing the need for multiple specialized tests and associated time losses.
