Motorized Bubble Wand Coating and Air Flow System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble generating toys require frequent dipping into a solution dish, leading to messy and wasteful handling of bubble solution, as they need continuous pouring and re-pouring, which results in spillage and inefficiency.
Innovation Solution
A bubble machine with a fan assembly, bubble dispenser, and wand motor assembly that automatically coats bubble wands with solution and blows air through them to generate bubbles vertically, eliminating the need for manual dipping and solution handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bubble rings are dipped into a dish of bubble solution to produce films, then bubbles can be generated, but continuous pouring and re-pouring of solution results in spillage and waste
Solution Approach 1:
The bubble machine automatically dips the bubble ring into the bubble solution and coats it with solution using a coating mechanism, eliminating the need for manual pouring and handling by the child. The system serves itself by automatically managing the solution application process.
Solution Approach 2:
A motorized mechanism acts as an intermediary between the bubble solution container and the bubble ring, automatically transferring and coating the solution onto the ring without requiring direct human handling of the solution container, thus preventing spillage.
2Productivity
If multiple bubble rings are used to generate a plurality of bubbles, then more bubbles can be produced, but the complexity of dipping and managing multiple rings increases
Solution Approach 1:
Multiple bubble rings are mounted together on a single rotating hub assembly, allowing them to be dipped, coated, and operated as one integrated unit rather than separate components, thus maintaining high productivity while reducing operational complexity.
Solution Approach 2:
The motor continuously rotates the hub assembly with multiple rings through the bubble solution and positions them for bubble generation, maintaining continuous operation without requiring repeated manual dipping actions for each ring.
3Productivity
If a motor is used to generate air against the bubble film, then bubbles are produced efficiently, but the device becomes more complex and requires power source management
Solution Approach 1:
An electric motor drives a fan or blower that generates a stream of air (pneumatic force) to blow against the bubble film on the rings, efficiently producing bubbles through aerodynamic pressure rather than manual blowing.
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 machine efficiently generates multiple bubbles vertically, reducing spillage and waste, while providing increased play variety and amusement by automating the bubble generation process.

AI summary
A bubble machine has a fan housing that is positioned inside a machine housing, and a fan coupled to the fan housing. A bubble dispenser is disposed over the machine housing and has an outer wall that defines a trough along a portion of its circumferential edge. The bubble dispenser includes an inner hub having a raised platform, and a bubble wand guiding mechanism on the platform. The outer wall and the inner hub define at least one space through which air generated by the fan can flow upwardly. A bubble wand assembly has a base, and a plurality of bubble wands that are disposed above the bubble dispenser in a manner such that each of the plurality of bubble wands is rotated past the trough to be coated with bubble solution, and then rotated over the at least one space so that air from below can be blown through the bubble wand to generate bubbles.
