Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If field observation is used to study water-sediment motion, then direct measurement data can be obtained, but the difficulty is high, cost is high, and safety is low
Solution Approach 1:
The patent creates a physical model system that copies the complex natural water-sediment environment in a controlled laboratory setting. The model flume reproduces key hydraulic and sediment transport characteristics without requiring field deployment, thereby achieving measurement objectives while avoiding the difficulties, costs, and safety risks of field observation.
2Productivity
If numerical simulation is used to study water-sediment motion, then simulation results can be obtained, but high performance computers are required and long-sequence simulations are costly and difficult
Solution Approach 1:
The patent segments the complex water-sediment system into controllable physical components within a model flume, allowing incremental experimentation and observation. This physical segmentation replaces the need for complex computational models, enabling long-sequence simulations through repeated physical experiments rather than computationally intensive numerical calculations.
3Device complexity
If a single-structure experiment device is used, then the structure is simple, but it cannot satisfy water-sediment asynchronous inflow conditions and sediment peak scheduling requirements
Solution Approach 1:
The patent introduces dynamic control capabilities to the experiment device, including variable flow rate mechanisms and adjustable sediment supply systems. These dynamic components allow the device to adapt to different experimental conditions such as water-sediment asynchronous inflow and various sediment peak scheduling scenarios, transforming a static simple structure into a versatile adaptive system.
4Manufacturing precision
If existing experiment devices are used, then the device is relatively low in cost, but it cannot achieve high-precision simulation of reservoir sediment peak scheduling
Solution Approach 1:
The patent designs a multi-functional experiment system that can perform various sediment peak scheduling simulations (different timing scenarios, different sediment types, different flow conditions) using a single integrated apparatus. This universal design achieves high-precision simulation capabilities without proportionally increasing system complexity, as the same core components serve multiple experimental purposes.
