Off-Center Nozzle Arrangement for Container Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing foreign substances from containers using gas flow are hindered by stagnation when nozzles are aligned along the centerline of the container, leading to reduced performance in dislodging foreign substances.
Innovation Solution
The nozzles are strategically positioned off-center, with a first nozzle spaced apart from the centerline on one side and a second nozzle on the other side, to prevent gas flow collision and stagnation, allowing for effective removal of foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If blower nozzles are disposed along the center line of the container, then the structure is simple and easy to implement, but the gas flow stagnates due to collision between inflow and outflow, deteriorating foreign substance removal performance
Solution Approach 1:
The patent applies asymmetry by positioning the blower nozzle at an off-center location relative to the container's center line. This asymmetric arrangement prevents the gas inflow from directly colliding with the outflow, eliminating flow stagnation and improving foreign substance removal performance while maintaining structural simplicity
Solution Approach 2:
The patent introduces a lateral dimension offset from the center line, moving the nozzle arrangement from a one-dimensional center-aligned configuration to a two-dimensional off-center configuration. This dimensional change creates non-collinear flow paths that prevent stagnation
2Force
If strong gas flow is inputted into the container, then foreign substances are more effectively discharged, but gas flow stagnation occurs when nozzles are centered, reducing the effectiveness
Solution Approach 1:
The asymmetric nozzle positioning ensures that strong gas flow can be maintained without stagnation by creating a flow path that does not collide with the outflow, thereby maintaining both high force and flow stability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This arrangement reduces gas flow stagnation and enhances the removal efficiency of foreign substances by maintaining consistent flow velocity and shear stress, effectively dislodging substances from the container's inner walls.
Implementation Method 1
a first nozzle configured to eject a gas toward the opening portion of the container
Implementation Method 2
maintaining consistent flow velocity and shear stress, effectively dislodging substances from the container's inner walls
