Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the physical model test system is made large to improve simulation accuracy, then the similarity to real site environment is improved, but excessive similar materials are required and large numbers of manpower and material resources are needed to replace the geologic form, wasting time and labor
Solution Approach 1:
The geologic body is divided into multiple detachable modules that can be independently assembled and disassembled. Each module represents a specific geologic structure (such as fault zones, landslide bodies, or normal geologic formations) and can be quickly replaced without affecting the entire model system, thus reducing the time and labor required for model reconfiguration while maintaining large-scale simulation accuracy.
Solution Approach 2:
The detachable modules can be removed (discarded) after one test and reused or replaced for subsequent tests. This allows the same physical model test system to be reused for multiple different geologic scenarios, significantly reducing the need to create entirely new large-scale models and thereby saving time and labor resources while preserving simulation accuracy.
2Loss of substance
If the physical model test system is made small to reduce material resources, then the resource consumption is reduced, but the similarity to real site environment decreases and the simulation result is quite different from real site environmental detection result
Solution Approach 1:
The physical model test system is designed with detachable modules that can be configured to represent different geologic structures and conditions. A single modular system can simulate various scenarios (faults, landslides, different stratigraphy) by reconfiguring the modules, making the system universally applicable to multiple detection scenarios. This allows a moderately-sized system to maintain high simulation accuracy across diverse applications without requiring excessive materials for each specific scenario.
3Stability of the object's composition
If the geologic body is fixed in the model test system to maintain structural stability, then the structural integrity is improved, but the geological form cannot be rapidly changed according to the site environment, and the model test system cannot be reused
Solution Approach 1:
The geologic body is segmented into detachable modules that maintain structural integrity within each module while allowing easy replacement at the module level. Each module is designed with connection interfaces that ensure stable assembly, so the overall system can be reconfigured by swapping modules rather than redesigning the entire structure, thus maintaining both structural stability and adaptability.
4Device complexity
If the observation mode is fixedly installed to simplify the system structure, then the device complexity is reduced, but rapid combination of different observation modes cannot be realized and the research efficiency is reduced
Solution Approach 1:
The observation system is designed with movable and adjustable components that can be dynamically reconfigured for different observation modes. Detachable observation devices can be positioned at various locations and orientations within the model, allowing rapid switching between different detection scenarios without requiring a completely fixed installation, thus balancing structural simplicity with operational flexibility and research efficiency.
