Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If hydraulic cylinders are used to push two box bodies for simulation, then the device structure is simple, but the fracture zone activity area is insufficient and activity intensity is limited
Solution Approach 1:
The device is divided into multiple box bodies (first box body, second box body, third box body) with a fracture zone formation space between them. This segmentation allows the fracture zone to have sufficient activity area while maintaining manageable device complexity through modular design.
Solution Approach 2:
Telescopic rods with universal joints are introduced to replace simple hydraulic cylinder pushing. The telescopic rods can extend and retract, providing dynamic adjustment capabilities that increase fracture zone activity area and intensity while allowing flexible simulation of earthquake fault movements.
2Area of stationary object
If a three-box-body test device is used to increase fracture zone width, then the fracture zone activity area is improved, but the test cost increases and operational flexibility is reduced
Solution Approach 1:
The telescopic rods are equipped with universal joints that can adapt to multiple directions and angles of movement. This universal connection assembly allows the same device structure to simulate various earthquake fault movement patterns, enhancing operational flexibility while maintaining an expanded fracture zone area.
Solution Approach 2:
The telescopic rods can dynamically adjust their length and orientation during testing, providing adaptability for different test scenarios. This dynamic capability allows the device to maintain operational flexibility while achieving sufficient fracture zone width through the spaced arrangement of box bodies.
3Stability of the object's composition
If fixed connection methods are used between box bodies, then the device structure is stable, but the simulation of realistic fault activities is limited
Solution Approach 1:
The connection between box bodies transitions from fixed to dynamic through the introduction of telescopic rods with universal joints. These joints allow the connection to adapt to various movement patterns while maintaining structural stability, enabling realistic simulation of earthquake fault activities including multi-directional dislocation and rotation.
Solution Approach 2:
The universal joint acts as an intermediary connection element between the telescopic rod and box bodies. It provides a stable yet flexible connection that accommodates complex movements, bridging the gap between structural stability and simulation versatility.
4Power
If telescopic rods with universal joints are used to connect box bodies, then the fracture zone activity intensity is improved, but the device complexity increases
Solution Approach 1:
The universal joint is a standardized mechanical component that provides multi-directional rotation capability. By using this universal component, the device achieves high fracture zone activity intensity without proportionally increasing complexity, as the universal joint is a well-understood and readily available mechanical element.
Solution Approach 2:
The connection assembly is segmented into modular components (telescopic rod, universal joints, support assemblies) that can be independently manufactured and assembled. This segmentation reduces overall complexity by allowing each component to be optimized separately and assembled through standard connection methods.
