Discharge Nozzle Tip Positional Stability Under Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional discharge devices experience deviations in the relative positional relationship between the nozzle tip and support body due to changes in internal pressure, leading to unstable discharge modes and potential failure in discharging contents properly.
Innovation Solution
A discharge device design where the support body is formed separately from the flow tube and nozzle tip, with a shaft portion and annular flange portion that maintain a stable positional relationship, ensuring consistent discharge even with increased internal pressure, through a discharge path with communication holes and grooves for even content distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nozzle tip is fitted to the flow tube and support body in a conventional integrated manner, then the structure is simple and easy to manufacture, but the relative positional relationship between the nozzle tip and support body changes when internal pressure increases, causing unstable discharge
Solution Approach 1:
The support body is separated from the flow tube and nozzle tip, forming an independent component. This segmentation allows the support body to move independently with pressure changes while maintaining the nozzle tip's stable position, preventing relative positional changes that would cause discharge instability. The separation resolves the contradiction by making the system more reliable without significantly increasing overall complexity.
Solution Approach 2:
The support body is designed to be movable relative to the flow tube, allowing it to dynamically adjust its position in response to internal pressure changes. This dynamic design enables the support body to move outward when pressure increases, while the nozzle tip remains fixed, thereby maintaining a stable discharge path and positional relationship.
2Reliability
If the support body is formed separately from the flow tube and nozzle tip, then the relative positional relationship is maintained under pressure changes, but the device structure becomes more complex
Solution Approach 1:
The support body is divided as a separate component from the flow tube and nozzle tip, allowing independent movement and position maintenance. This segmentation enables the support body to respond to pressure changes without affecting the nozzle tip's position, ensuring positional stability while keeping the separation manageable.
Solution Approach 2:
The support body serves multiple functions: it provides structural support, guides the discharge path, and acts as a movable element that responds to pressure changes. By consolidating these functions into a single separable component, the design achieves positional stability without proportionally increasing the number of components.
3Ease of manufacture
If the nozzle tip moves with respect to the flow tube and support body due to increased internal pressure, then the结构简单 (structure is simple), but the discharge mode becomes unstable and spinning is improper
Solution Approach 1:
The support body is segmented as a separate component that can move independently, allowing the nozzle tip to maintain a precise, stable position relative to the flow tube. This segmentation ensures that even though the support body moves with pressure changes, the critical nozzle tip position remains stable, maintaining discharge precision.
Solution Approach 2:
The support body is designed to move dynamically in response to pressure changes, while the nozzle tip remains fixed in its precise position. This dynamic design allows the system to accommodate pressure variations without compromising the precision of the discharge path and spinning effect.
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 design allows for stable and consistent discharge of contents without being affected by changes in internal pressure, ensuring proper spinning and even distribution, thus maintaining a constant discharge mode.
Implementation Method 1
when an internal pressure of a flow tube increases, the contents can be introduced from the inside of the flow tube to the discharge hole through the discharge path
Implementation Method 2
a spin flow path which allows communication between an inside of the flow tube and the discharge hole is formed between an inner surface of the nozzle tip and an outer surface of the support body
