Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional hydropower generation is implemented with dams, then power generation capacity is improved, but construction cost and environmental impact increase significantly
Solution Approach 1:
The invention segments the hydropower generation system into modular components: a water hammer power generation device that can be independently installed without requiring large-scale dam construction. The system divides the water flow utilization into discrete impact events rather than continuous flow through turbines, enabling distributed generation across multiple small units.
Solution Approach 2:
The invention extracts the core energy conversion mechanism from traditional hydropower by isolating the water hammer effect as the primary power source. Instead of using the entire water flow system with dams and reservoirs, only the essential water flow and impact mechanism are retained, eliminating the need for extensive civil engineering infrastructure.
2Device complexity
If the water hammer effect is used for power generation, then construction cost is reduced, but power output stability deteriorates
Solution Approach 1:
The system employs periodic water flow interruption to generate repeated water hammer impacts. The control valve opens and closes at regular intervals, creating a sequence of pressure waves that drive the piston reciprocally. This periodic action transforms intermittent water hammer events into continuous rotational motion of the crankshaft, ensuring stable power output.
Solution Approach 2:
The invention ensures continuous power generation by maintaining an unbroken sequence of water hammer impacts. The control valve is designed to close rapidly after each opening, ensuring that water flow is continuously interrupted to generate successive pressure waves. This continuous cyclic action prevents gaps in power generation and maintains stable output.
3Force
If rapid valve closure is used to generate water hammer effect, then impact force is improved, but water leakage increases
Solution Approach 1:
The invention converts the harmful water leakage that occurs during rapid valve closure into a beneficial feature. The loosened ring is specifically designed to allow controlled water drainage during the valve closure process, which actually helps reset the system for the next water hammer event. What would normally be considered waste or damage is transformed into a functional element that facilitates continuous operation.
Solution Approach 2:
The system changes the parameters of water flow control by using a loosened ring structure instead of tight sealing. This structural parameter change allows the system to tolerate and utilize water leakage during valve operation, converting a potential disadvantage into an operational advantage that enables faster valve closure and stronger water hammer effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves efficient energy conversion by maximizing the water hammer impact, ensuring continuous and stable power output, reducing environmental impact, and enabling widespread hydropower generation without large dams.
Implementation Method 1
When the trigger valve (16) is closed, an instantaneous pressure wave is generated due to an inertia of water flow, and the instantaneous pressure wave will impact the piston (25) and the wall of pipes like a hammer, thereby generating the water hammer effect.

AI summary
A power system of water hammer effect includes a pressure cylinder connected to a pressure water pipe. A pressure branch pipe is disposed on the pressure water pipe, and a trigger valve is mounted on the pressure branch pipe. The pressure cylinder defines a hollow chamber, a piston is slidably mounted inside the hollow chamber, and a piston rod is mounted on an end of the piston, penetrates to an outside of the pressure cylinder and slidably connected to the pressure cylinder. The hollow chamber defines a drainage cavity therein, which includes a loosened ring and a drainage collection ring, and the drainage collection ring defines a drainage port thereon. The loosened ring and the drainage collection ring on cylinder body inner wall drain and release pressurized water inside the system, so that the piston quickly returns to its position without impact or compression, and enters a next stamping stroke.
