Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble production devices, such as machines, are often large, complex, and not portable, making them difficult for children to operate and limiting the portability and ease of use for creating soap bubbles.
Innovation Solution
A bladeless bubble fan device that uses a housing with an impeller and air guide to create a plenum, directing airflow through a bubble ring with closely spaced fins to produce bubbles without blades, allowing for portable and child-friendly bubble creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional bubble machines are used to produce quantities of bubbles, then bubble production capability is improved, but device size and complexity increase, reducing portability and ease of operation
Solution Approach 1:
The device segments the bubble generation function into a simple bubble ring with slots that interfaces directly with airflow, eliminating the need for complex mechanical bubble-making components. The housing is segmented into functional zones (air intake, impeller chamber, bubble ring area, outlet) that work independently but cooperatively.
Solution Approach 2:
The invention extracts and eliminates the traditional fan blades that were necessary in conventional bubble machines, replacing them with a bladeless design where the impeller is enclosed within the housing. This removes the complexity of blade mechanisms while maintaining air movement capability for bubble production.
2Productivity
If traditional bubble machines are used to produce quantities of bubbles, then bubble production capability is improved, but device size increases, reducing portability
Solution Approach 1:
The impeller is nested within the housing, with the bubble ring positioned at the outlet where it receives airflow directly from the impeller. The air guide channels are nested within the housing structure, creating a compact nested arrangement of functional components that maximizes space efficiency.
Solution Approach 2:
The housing serves multiple functions simultaneously: it encloses the impeller, provides structural support, defines the air outlet, and positions the bubble ring. The air guide both directs airflow and supports the bubble ring, combining multiple functions into single components to reduce overall device volume.
3Productivity
If traditional bubble machines are used, then bubble production capability is improved, but ease of operation for children decreases due to complexity
Solution Approach 1:
The device is designed to be operated simply by a child holding and activating it, with the bubble ring positioned to receive solution from the user's hand or a attached reservoir. The automatic airflow generation and bubble formation process requires minimal user intervention beyond providing bubble solution, making it self-operating once activated.

AI summary
A bladeless bubble fan includes a housing defining a plurality of inlets and having enclosed therein an impeller for drawing air through the inlets from an exterior thereof, at least a portion of the housing forming a closed geometrically shaped outer shell and defining an axial passageway therethrough. An inner air guide is received in the housing and coaxial with the closed geometrically shaped outer shell and in combination with the outer shell defines a plenum therebetween in fluidic communication with an output of the impeller and further defines a peripheral outlet of the plenum. A bubble ring is affixed to the inner air guide and coaxial therewith. The bubble ring has a plurality of closely spaced fins extending inwardly toward an axis of the axial passageway.
