Pressurized Bubble Maker With Elastic Liquid Storage Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble makers for inflatable amusement devices face challenges in producing continuous bubbles due to the bulkiness and weight of soap water containers, which are inconvenient to load and install, especially when a better bubble effect requires the container to be positioned higher than the device.
Innovation Solution
A bubble maker design featuring a pressurized container with a liquid storage bag made of elastic material, connected by a drainage tube to a bubble generator, where the pressurized container introduces fluid to squeeze the bubble solution into the generator, using tap water or air to facilitate continuous bubble production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large container or liquid storage bag is used to store soap water for continuous bubble production, then the bubble production continuity is improved, but the weight and bulkiness increase making it inconvenient to load and install
Solution Approach 1:
The system is divided into two separate functional components: a pressurized container that receives external fluid pressure and an elastic liquid storage bag that actually holds the soap solution. This segmentation allows the heavy pressurization system to be separate from the liquid storage, enabling continuous operation without proportionally increasing the weight of the liquid-carrying component.
Solution Approach 2:
The patent introduces a pressurized container with fluid inlet that uses external fluid (water or air) pressure to compress the elastic liquid storage bag and force soap solution through the drainage tube to the bubble generator. This pneumatic/hydraulic mechanism enables continuous bubble production by maintaining pressure on the liquid storage bag without requiring the container itself to be heavily weighted or permanently mounted at height.
2Manufacturing precision
If the container is positioned higher to achieve better bubble effect, then the bubble generation quality is improved, but the installation difficulty increases
Solution Approach 1:
The liquid storage bag is made of elastic material and is disposed within the pressurized container, allowing the system to be dynamically positioned. The elastic bag can deform and adapt to different positions while maintaining its function, enabling installation at various heights without requiring rigid structural support at elevated positions.
Solution Approach 2:
By using fluid pressure from the pressurized container to drive the soap solution through the drainage tube to the bubble generator, the system eliminates the need for gravitational feed requiring high positioning. The pressurization mechanism allows the bubble generator to be positioned at optimal height for bubble generation while the liquid storage can be positioned conveniently for installation and refilling.
3Duration of action of moving object
If a bulky container is used to store sufficient soap water, then the bubble production duration is improved, but the device complexity increases
Solution Approach 1:
The elastic liquid storage bag is disposed inside the pressurized container, creating a nested structure where the liquid storage bag is contained within the pressure application chamber. This nesting allows the system to maintain a compact overall form factor while providing sufficient soap water storage capacity and continuous pressurization, avoiding the need for separate heavy-duty external tanks and mounting structures.

AI summary
A bubble maker includes a pressurized container; a liquid storage bag; a bubble generator; and a drainage tube connecting the liquid storage bag and the bubble generator. The liquid storage bag is configured to store a bubble solution. The drainage tube is configured to convey the bubble solution to the bubble generator; and the bubble generator is configured to convert the bubble solution into bubbles. The liquid storage bag includes elastic material and is disposed in the pressurized container. The pressured container includes a fluid inlet so that a fluid is introduced to the pressured container via the fluid inlet to squeeze the liquid storage bag, and thus the bubble solution in the liquid storage bag is squeezed into the bubble generator via the drainage tube.
