Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex structure with fixed partition wall and aperture is used in the vortex throttle device, then the device can maintain a stable throttling effect, but the device becomes difficult to adapt to different installation situations and flow requirements
Solution Approach 1:
The partition wall with the aperture is made as a separate, detachable component from the housing. This segmentation allows the aperture section to be easily removed, replaced, or adjusted without affecting the main housing structure, enabling adaptation to different installation situations and flow requirements while maintaining a relatively simple overall device design.
2Adaptability or versatility
If the aperture opening is fixed in size, then the manufacturing process is simplified, but the device cannot be adjusted to accommodate different outflow characteristics and discharge requirements
Solution Approach 1:
The aperture opening is designed to be dynamically adjustable rather than fixed. The detachable partition wall component can be replaced with different aperture sizes or configurations to match different discharge requirements, allowing the device to adapt to varying outflow characteristics while maintaining manufacturing simplicity through standardized connection interfaces.
3Ease of operation
If a modular housing structure is implemented for flexible installation depths, then the device becomes easier to install at different locations, but the structural integrity and sealing may become more challenging
Solution Approach 1:
The housing is divided into modular sections that can be assembled at different installation depths. Standardized connection interfaces and sealing elements are provided at the joints between modular sections, enabling flexible installation while maintaining reliable sealing through consistent connection designs that can be manufactured and installed uniformly across different locations.
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 solution simplifies the structure, enhances adaptability, and improves the throttling effect by allowing for easy adjustment of the aperture opening and modular installation, ensuring efficient water management and flood protection.
Implementation Method 1
The liquid inlet flows essentially tangentially into the vortex chamber (50), thereby stimulating the formation of a vortex flow in the vortex chamber (50)
Implementation Method 2
the air-filled vortex core extends through the aperture (32). This limits the cross-sectional area of the aperture used for the passage of water and increases the throttling effect of the aperture (32)
