Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single simulation device is used, then resource efficiency is improved, but the ability to simulate different fault types (normal and reverse faults) and adjust parameters (fault angle, fracture initiation position) deteriorates
Solution Approach 1:
The simulation device is designed with multiple loading apparatuses (first loading apparatus for vertical loading, second loading apparatus for lateral loading) and adjustable components (angle adjusting apparatus, position adjusting apparatus) that enable a single device to perform multiple simulation functions including normal faults, reverse faults, and various fault angles, eliminating the need for multiple specialized devices
Solution Approach 2:
The device incorporates adjustable components including the angle adjusting apparatus that can change the inclination angle of the baffle plate, and the position adjusting apparatus that can move the fracture initiation position, allowing the device to dynamically adapt to different simulation requirements rather than being fixed for a single fault type
2Device complexity
If existing simulation devices are used, then device simplicity is maintained, but the precision of controlling fault angle and fracture initiation position deteriorates
Solution Approach 1:
The loading system is divided into separate first and second loading apparatuses, and the adjusting functions are segmented into distinct angle adjusting and position adjusting apparatuses, allowing each component to be relatively simple while collectively achieving precise control of fault angle and fracture initiation position
3Adaptability or versatility
If multiple devices are used to simulate different faults, then simulation versatility is improved, but time consumption and operational complexity increase
Solution Approach 1:
A single simulation device is designed with multiple loading apparatuses and adjusting mechanisms that can simulate both normal and reverse faults with various angles and fracture initiation positions, eliminating the need to switch between multiple devices and significantly reducing setup time and operational complexity

AI summary
A coal measures fault formation simulation experimental device and a normal and reverse fault simulation experiment method relate to the field of similar material simulation experiment technology. The device includes a hydraulic lifting apparatus, a lower angle adjusting apparatus, a push rod apparatus, an upper loading apparatus, an upper angle adjusting apparatus, a lateral loading apparatus and a transparent side plate. The hydraulic lifting apparatus and the lower angle adjusting apparatus are below the experimental body, the upper loading apparatus and the upper angle adjusting apparatus are above the experimental body, the transparent side plate is disposed at a rear side surface of the experimental body, and the lateral loading apparatus is disposed at an end face of the experimental body. When the normal fault is simulated with the device, the inclination angle of an inclined plate of the lower angle adjusting apparatus is same as that of an inclined push plate of the upper angle adjusting apparatus, the upper loading apparatus loads downward to form a normal fault.
