Solution Overview
Problem
Conventional bubble generating machines are large, inefficient, and unable to produce continuous streams of bubbles in a vertical direction, leading to bubble wastage and contamination.
Innovation Solution
A compact bubble generating machine design with a motor and impeller configuration reversed and the bubble wheel positioned at a right angle, allowing for simultaneous rotation of the impeller and turntable, and an airflow channel redirecting airflow from horizontal to vertical, reducing the machine's size and improving bubble production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the bubble generating machine is placed on a horizontal surface and blows bubbles in a horizontal direction, then the machine structure is simple, but a significant number of bubbles burst on the horizontal surface causing waste and contamination
Solution Approach 1:
The patent inverts the conventional horizontal bubble blowing direction to a vertical direction by repositioning the impeller above the bubble wheel and redirecting airflow upward. This inversion prevents bubbles from contacting the horizontal surface, eliminating burst bubbles and associated waste without requiring complex additional components.
Solution Approach 2:
The patent changes the bubble release from a two-dimensional horizontal plane to a three-dimensional vertical trajectory by positioning the bubble wheel vertically and directing airflow upward through an extension. This dimensional change allows bubbles to rise away from surfaces, preventing contact and burst.
2Volume of moving object
If the motor and gear box are positioned in-line with the bubble wheel to rotate it, then the wheel can be rotated effectively, but the machine requires a long horizontal length making it quite large
Solution Approach 1:
The patent nests the motor and gear box within the vertical space occupied by the bubble wheel assembly rather than positioning them in-line horizontally. The motor is positioned above the bubble wheel, and the gear box is integrated into this vertical arrangement, allowing the components to occupy overlapping spatial volumes and reducing the overall machine footprint.
Solution Approach 2:
The patent transitions from a horizontal component arrangement to a vertical arrangement, stacking the motor, gear box, and bubble wheel along the vertical axis. This dimensional reorganization reduces the horizontal length requirement while maintaining effective power transmission to the bubble wheel.
3Productivity
If the motor and gear box are positioned to rotate the bubble wheel, then the wheel rotation is achieved, but the motor and gear box partially block the airflow produced by the impeller reducing efficiency
Solution Approach 1:
The patent extracts the motor and gear box from the airflow path by positioning them vertically above and around the bubble wheel rather than in-line with the impeller. This separation removes the blocking effect on airflow while maintaining the mechanical connection needed for bubble wheel rotation.
Solution Approach 2:
The patent rearranges components from a horizontal in-line configuration that blocked airflow to a vertical configuration where the motor and gear box are positioned above the bubble wheel, allowing airflow to pass unobstructed through the bubble wheel area while still achieving effective rotation.
4Ease of operation
If the bubble wheel is positioned at right angles to the impeller airflow, then vertical bubble streams are produced, but the machine requires reconfiguration reducing compactness
Solution Approach 1:
The patent inverts the conventional configuration by positioning the impeller above the bubble wheel and directing airflow upward rather than horizontally. This inversion achieves vertical bubble streams while maintaining compact dimensions by utilizing the vertical space within the existing machine footprint.

Function Achieved in This Case
The machine produces a continuous stream of bubbles in a vertical direction, reducing waste and contamination, while being more compact and efficient, with a safer design due to the friction-based attachment of the turntable rotator.
Implementation Method 1
an impeller positioned inside the housing; and a motor positioned inside the housing and operatively coupled to the impeller
Implementation Method 2
