Bubble Wall Fruit Fly Trap Using Recirculating Air Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for removing fruit flies, such as toxic chemicals and physical traps, pose health risks and are unsightly or require frequent disposal, making them unsuitable for public areas like bars and restaurants.
Innovation Solution
A chemical-free fly trap that uses an air pump to create a cascading wall of bubbles, which appears as a solid surface to flies, entrapping them, and a reusable design with a bait/bubble solution that recirculates to collect and drown flies, maintaining sanitation and ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional physical traps (dangling adhesive tapes) are used to remove fruit flies, then some flies are successfully removed from the local environment, but the traps become unsightly and require frequent disposal in public areas
Solution Approach 1:
The trap system automatically recirculates the bubble solution through pumping mechanisms, creating continuous bubble walls without manual intervention. The system self-maintains the bubble generation process, reducing the need for frequent human disposal and replacement of trap components.
Solution Approach 2:
The trap design allows the solution to be separated from captured flies through filtration or decanting, enabling the solution to be reused multiple times. This recovering process extends the operational life of the trap medium, reducing disposal frequency while maintaining fly removal effectiveness.
2Productivity
If toxic chemicals are used to remove fruit flies, then fly removal effectiveness is improved, but health risks increase if not handled or disposed properly
Solution Approach 1:
The patent converts the naturally occurring attraction of flies to fermenting liquids (which could be seen as a harmful aspect of their behavior) into a beneficial trapping mechanism. The same fermenting aroma that attracts flies is used to lure them into the trap, while the physical bubble wall and drowning mechanism eliminate the need for toxic chemicals.
Solution Approach 2:
The patent replaces chemical trapping mechanisms with a physical-mechanical system involving air pumps, bubble generation, and fluid circulation. This mechanical approach uses pressurized air to create bubble walls and pumping systems to circulate the solution, eliminating toxic chemicals while maintaining fly removal effectiveness.
3Productivity
If traditional trap systems are used, then flies are captured, but the traps require frequent disposal and replacement
Solution Approach 1:
The trap design allows the solution to be separated from captured flies through filtration or decanting, enabling the solution to be reused multiple times. This recovering process extends the operational life of the trap medium, reducing disposal frequency while maintaining fly removal effectiveness.
Solution Approach 2:
The continuous circulation of the bubble solution through pumping mechanisms ensures the trap remains effective over extended periods. The system maintains continuous bubble generation and solution refreshment, preventing the degradation that would normally require trap replacement.
4Productivity
If dangling adhesive tapes are used in public areas, then flies are removed, but the visual appearance becomes unsightly and intrusive
Solution Approach 1:
The trap uses a transparent or translucent container design with thin wall structures that allow the internal bubble activity to be visible yet not intrusive. The transparent construction enables the trap to blend into public environments while maintaining aesthetic appeal, unlike opaque adhesive tapes.
Solution Approach 2:
The cascading water feature design creates a visually appealing replication of natural water flow patterns, transforming the functional trap into an aesthetic element. This copying of natural phenomena makes the trap desirable in public spaces rather than intrusive.
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
Effectively captures fruit flies without using toxic chemicals, maintaining sanitation and reducing maintenance, as the trap is reusable and easy to clean, making it suitable for public areas.
Implementation Method 1
The air forms bubbles in the solution that rise in the space formed between the outer wall and the inner wall and that cascade downward within the inner wall and into the solution
Implementation Method 2
The air forms bubbles in the solution that rise in the space formed between the outer wall and the inner wall
Implementation Method 3
The bait/bubble solution continually circulates creating a moving body of bubbles (e.g., like a conveyer belt, for example), which returns back to the original location and becomes liquid again to make more bubbles

AI summary
Disclosed herein is a trap for flying pests that does not require the use of chemicals and can be packaged in such a way that it can be present in public areas without being unsightly or intrusive. The trap is reusable, easy to set up, easy to clean, and easy to operate. An example trap includes an outer wall containing a solution, an inner wall extending into the solution, and a space formed between the outer wall and the inner wall. The trap also includes an air pump and one or more air supply conduits that supply air from the air pump to the solution. The air forms bubbles in the solution that rise in the space formed between the outer wall and the inner wall and that cascade downward within the inner wall and into the solution. The cascading bubbles serve to capture flies that land on the bubbles and retain the flies within the trap.
