Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current simulation test equipment is used, then simple environmental changes can be simulated, but complex marine dynamic environments cannot be simulated
Solution Approach 1:
The simulation test equipment is divided into multiple independent functional modules: seawater circulation module, water level control module, climate simulation module, and force loading module. Each module independently simulates a specific marine environment factor, allowing complex marine dynamic environments to be simulated through coordinated operation of multiple simple modules, thus improving simulation capability without significantly increasing overall equipment complexity
Solution Approach 2:
The test chamber is designed as a multi-functional platform that can simultaneously accommodate seawater immersion, climate exposure, and mechanical loading tests. The circulation mechanism serves multiple purposes including seawater simulation, water level control, and flow rate regulation. This multi-functionality allows a single equipment system to simulate complex marine dynamic environments encompassing multiple environmental factors
2Adaptability or versatility
If seawater circulation is simulated, then marine erosion can be studied, but water level control becomes difficult
Solution Approach 1:
A water level sensor is installed in the test chamber to detect the actual water level position. The sensor signal is fed back to the control system, which automatically adjusts the circulation mechanism to maintain the water level within the preset range. This closed-loop feedback control enables precise water level control while maintaining seawater circulation, resolving the operational difficulty
3Measurement precision
If comprehensive marine environment simulation is implemented, then research accuracy improves, but test system complexity increases
Solution Approach 1:
The test system is segmented into independent functional modules (seawater circulation, water level control, climate simulation, force loading), each responsible for simulating a specific environmental factor with high precision. This modular segmentation allows accurate simulation of comprehensive marine environments while keeping each individual module relatively simple and manageable
Solution Approach 2:
A central control system acts as an intermediary that coordinates the operation of multiple simulation modules. The control system receives preset parameters for various environmental factors and automatically regulates each module to achieve the desired comprehensive marine environment, thereby improving simulation accuracy without requiring complex manual coordination of each component
