Bubble Presentation Vortex Airflow for Stable Midair Floating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing presentation devices utilizing bubbles do not effectively utilize the characteristics of floatable and light mass properties of bubbles, as they are typically confined to contact with containers or human fingers.
Innovation Solution
A system comprising a tornado fan with multiple blowers generating vortex air flows, a bubble pump, suction and ceiling/floor fans, and sensors for controlling air flow and bubble generation, allowing bubbles to float and sustain in a presentation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bubbles are used in conventional presentation devices, then light diffusion and visual atmosphere are improved, but the floatable characteristic of bubbles is not utilized and bubbles remain confined to contact with containers or fingers
Solution Approach 1:
The patent applies the anti-weight principle by using upward air flow generated by fans to counteract the gravitational force acting on bubbles. The air flow creates a buoyant effect that opposes gravity, allowing bubbles to float and suspend in midair rather than settling on surfaces or requiring container contact for stability.
2Reliability
If multiple fans are used to generate vortex air flow, then bubble floating and suspension are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple fan units into a coordinated system where multiple fans work together to generate a unified vortex air flow pattern. The fans are positioned and controlled to create a combined aerodynamic effect that suspends bubbles collectively, rather than using individual fans for separate functions.
Solution Approach 2:
The patent employs vortex air flow with curved, rotational motion patterns created by the arranged fans. This curved airflow structure naturally traps and suspends bubbles in a stable manner, utilizing the rotational dynamics to maintain bubble position without requiring complex mechanical constraints.
3Adaptability or versatility
If vortex air flow is generated to float bubbles, then midair presentation is enabled, but control and measurement of bubble position becomes more difficult
Solution Approach 1:
The patent implements a feedback control system where sensors detect the positions of floating bubbles and this information is fed back to the control unit. The control unit adjusts the air flow from the fans in real-time based on the detected positions, maintaining stable bubble suspension and enabling precise control despite the dynamic air flow environment.

AI summary
The presentation system 100 comprises: a tornado fan in which a plurality of blowers each perform blowing so that clockwise or counterclockwise air flow is generated in a presentation space surrounded by exhaust ports 114 of the plurality of blowers when viewed in a plan view; and a supply device 12 that supplies a float body such as a bubble into the presentation space. It is possible to cause an aggregate of bubbles to float in the vicinity of the center in the presentation space by means of a vortex air flow formed in the presentation space.
