Engineering Contradiction Analysis
1Reliability
If complex devices and technologies are used for separating and combining fluids, then the reliability of fluid separation and combination is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines the separation and combination of fluids into a single integrated mixing chamber design, eliminating the need for separate complex devices. The mixing chamber geometry itself performs both functions through its specific structural configuration, reducing device complexity while maintaining reliability.
Solution Approach 2:
The mixing chamber is designed to automatically separate and combine fluids based on pressure gradients and flow dynamics without requiring additional control mechanisms or complex auxiliary devices. The system uses the inherent properties of the fluids and the chamber geometry to achieve reliable separation and combination.
2Productivity
If energy is consumed for pumping fluids to generate high-energy jets, then the flow rate and temperature of the fluid jet are improved, but the energy efficiency of the power plant decreases
Solution Approach 1:
The patent converts the pressure difference, which would normally represent energy loss, into a beneficial force that accelerates the suction fluid. The pressure gradient that exists after fluid combination is utilized to drive the mixing process and accelerate the jet, transforming what would be waste energy into useful kinetic energy.
Solution Approach 2:
The invention changes the pressure parameters within the mixing chamber to create a favorable pressure gradient. By designing the chamber geometry to produce higher pressure in the suction fluid introduction area compared to the propellant fluid area, the system achieves automatic acceleration of the suction fluid without additional pumping energy.
3Productivity
If energy is consumed for pumping fluids to generate high-energy jets, then the temperature of the fluid jet is improved, but the energy efficiency of the power plant decreases
Solution Approach 1:
The patent utilizes phase transition of the suction fluid as it accelerates through the pressure gradient. The fluid undergoes adiabatic expansion and cooling as it moves from high to low pressure regions, which can induce phase changes that contribute to the thermal characteristics of the final jet while maintaining energy efficiency.

The nozzle module increases the efficiency of the power plant by energically enriching the propellant fluid, leading to improved temperature and flow rate of the fluid jet, thus enhancing energy production with minimal energy input and reducing material fatigue.
Implementation Method 1
a gas pressure in the mixing chamber in an area after the first nozzle is lower than a gas pressure in the mixing chamber in an area after the introduction opening
Implementation Method 2
Due to the higher vapor pressure of the suction fluid, this evaporates more easily than the propellant fluid and can be present in gaseous form after flowing through the inlet opening
Implementation Method 3
the propellant fluid and the suction fluid are combined, with energy from the suction fluid being transferred to the propellant fluid
