Adjustable Air Duct for Bubble Machine Blowing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble machines have a fixed horizontal blowing angle, which is not adaptable to diverse practical requirements and results in weak airflow and inefficient bubble production due to bubble rings being arranged radially on the rotary table, leading to small airflow and high intermediate loss.
Innovation Solution
A bubble machine with an adjustable blowing angle, featuring a double-shaft motor, rotary table with bubble rings arranged normally, a rotatable air duct, and an adjustable slideway allowing the air outlet to be adjusted from 0-90 degrees, along with remote control and automatic liquid replenishment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the blowing angle is fixed horizontally, then the structure is simple, but the adaptability to diverse practical requirements is poor
Solution Approach 1:
The air duct is designed with a rotatable joint that allows it to change its blowing angle dynamically. The air duct can rotate relative to the housing, transforming from a fixed horizontal structure to an adjustable one, enabling adaptation to different practical requirements while maintaining structural simplicity through a single rotational degree of freedom
Solution Approach 2:
The invention introduces angular adjustment capability by adding a rotational dimension to the air duct. The air duct can now operate in multiple angular positions (0-90 degrees) in addition to its original horizontal orientation, effectively adding a dimensional degree of freedom that enhances adaptability without significantly complicating the overall structure
2Productivity
If the bubble rings are arranged radially on the rotary table, then the structure is compact, but the airflow is weak and intermediate loss is high
Solution Approach 1:
Instead of arranging bubble rings radially on the rotary table, the invention inverts the arrangement by placing the bubble rings on a separate circular track that is positioned perpendicular to the rotary table's rotation axis. This inversion allows the air flow to approach the bubble rings from a more favorable direction, reducing intermediate loss and improving bubble production efficiency
Solution Approach 2:
The invention introduces an intermediary circular track structure that mediates between the rotary table and the bubble rings. This intermediary track allows for optimized airflow paths and better positioning of bubble rings relative to the air supply, reducing energy loss while maintaining compact structure
3Adaptability or versatility
If the air duct angle is adjustable from 0-90 degrees, then the versatility for various scenarios is improved, but the control complexity increases
Solution Approach 1:
The air duct incorporates a rotatable joint that enables dynamic angle adjustment from 0 to 90 degrees. This single rotational degree of freedom provides versatile control for different scenarios while keeping the adjusting mechanism relatively simple, avoiding the need for complex multi-axis adjustment systems
