Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional elements such as flap valves are used for flow regulation, then flow control capability is improved, but pressure drop increases and turbulence is generated requiring silencers
Solution Approach 1:
The nozzle incorporates a mobile element that can dynamically adjust the passage area to regulate flow. This dynamic adjustment mechanism allows the nozzle to adapt to different flow requirements without requiring additional static regulation elements, thereby maintaining lower pressure drops while providing effective flow control capability.
Solution Approach 2:
The nozzle is designed to perform multiple functions: it serves as both the flow delivery component and the flow regulation component. The mobile element integrated into the nozzle structure enables the same component to both transport fluid and control its flow rate, eliminating the need for separate flap valves and reducing overall system complexity.
2Ease of operation
If additional elements such as flap valves are used for flow regulation, then flow control capability is improved, but turbulence increases requiring silencers
Solution Approach 1:
The mobile element provides dynamic flow regulation by adjusting the passage area in a controlled manner. This dynamic adjustment creates smoother flow transitions compared to static flap valves, reducing turbulence generation while maintaining effective flow control capability across different operating conditions.
3Ease of operation
If conventional flow regulation devices are used, then flow control is achieved, but device complexity increases due to need for silencers and additional regulators
Solution Approach 1:
The nozzle is designed as a multi-functional component that simultaneously serves as the flow delivery mechanism and the flow regulation device. The integrated mobile element within the nozzle structure eliminates the need for separate flap valves, silencers, and flow regulators, thereby reducing device complexity while maintaining effective flow control.
Solution Approach 2:
The invention merges the functions of flow delivery and flow regulation into a single integrated nozzle component. By combining these previously separate functions into one unified device with a mobile adjustment element, the system reduces the total number of components needed while achieving the same or improved flow control performance.
4Speed
If passage area is reduced to increase fluid speed, then kinetic energy is improved, but pressure drop increases
Solution Approach 1:
The mobile element enables dynamic adjustment of the passage area, allowing the system to optimize the balance between fluid speed and pressure drop. By providing controlled, incremental adjustments rather than fixed reductions, the nozzle can achieve the desired fluid speed while minimizing unnecessary pressure losses through optimized flow path management.
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 adjustable nozzle achieves low pressure drop and low-turbulence profiles, enabling efficient flow control and noise reduction across a range of operating conditions, simplifying the control mechanism and reducing the need for additional noise mitigation equipment.
Implementation Method 1
transforming the energy stored in the fluid in the form of enthalpy (pressure energy + energy or thermal state) into kinetic energy. This transformation is achieved by means of variations of the flow passage area.
Implementation Method 2
The high-speed fluid leaving the nozzle is normally called a jet and the carrying phenomenon caused by this jet is called induction or entrainment depending on the field of application.
