Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble generating machines require frequent dipping into a solution dish, leading to messy spillage and increased production costs due to complex constructions and pump systems, while lacking simplicity and variety in bubble sizes.
Innovation Solution
A bubble machine with a fan assembly and bubble wand assembly that automatically generates different-sized bubbles by rotating bubble wands over a solution collection section, eliminating the need for manual dipping and using motors to blow air through the wands, thus producing large and small bubbles simultaneously.
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 the child must continuously pour and re-pour solution which causes spillage and waste
Solution Approach 1:
The bubble solution container is designed to automatically dispense solution to the bubble rings through gravity feed and capillary action, eliminating the need for manual pouring. The system serves itself by maintaining a continuous supply of solution to the generating elements without human intervention.
Solution Approach 2:
The bubble solution is pre-loaded into the container before use, and the system is pre-configured with the solution reservoir positioned above the bubble rings. This preliminary preparation eliminates the need for continuous pouring during operation.
2Extent of automation
If a pump system is used to deliver bubble solution to bubble generating wands, then automatic bubble generation is achieved, but the construction becomes complex and production costs increase
Solution Approach 1:
The mechanical pump system is replaced with a gravity-based passive delivery system. Bubble solution flows automatically from the elevated container to the bubble rings through gravity and capillary action, eliminating motors, pumps, and complex mechanical components while maintaining automatic operation.
Solution Approach 2:
The pump mechanism is completely extracted from the system. Instead of using active mechanical delivery, the invention uses passive gravity-fed solution transfer, removing the complex pump system entirely while achieving the same automatic bubble generation function.
3Productivity
If multiple bubble rings are used to generate numerous bubbles, then productivity increases, but the device complexity and production costs increase
Solution Approach 1:
The bubble generating system is segmented into multiple independent rings arranged in a cluster, each capable of generating bubbles simultaneously. This segmentation allows high productivity through parallel operation while keeping each individual ring simple in design and easy to manufacture.

AI summary
A bubble machine has a fan assembly that has a fan housing, and a fan coupled to the fan housing. A bubble dispenser is disposed above the fan housing, and has a mounting section that is secured inside the fan housing, and a bubble solution collection section covering the fan below. The housing, the mounting section and the bubble solution collection section define at least one space through which air generated by the fan can flow upwardly. A bubble wand assembly has 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 over the bubble solution collection section 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.
