Ultrafine Bubble Liquid Buffer Tank for Uninterrupted Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrafine bubble-containing liquid production apparatuses face interruptions when a constituent element, such as the UFB generator or pump, malfunctions, leading to disruptions in the production process.
Innovation Solution
Incorporating a buffer tank and controller to accumulate and manage ultrafine bubble-containing liquid, allowing continuous delivery even when the producing unit stops operating, ensuring uninterrupted supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a circulation route is implemented to repeatedly pass liquid through the UFB generator, then the concentration of contained UFBs is raised, but the system becomes vulnerable to interruptions when components break
Solution Approach 1:
The buffer tank accumulates UFB-containing liquid in advance during normal operation, creating a reserve that can be used when the producing unit stops operating. This preliminary accumulation ensures that the liquid delivering unit can continue delivering accumulated liquid even when the producing unit is stopped for maintenance or repair of components like the UFB generator or pump.
Solution Approach 2:
The buffer tank acts as an intermediary between the producing unit and the liquid delivering unit. It decouples the continuous delivery function from the intermittent production function, allowing the delivering unit to operate continuously by drawing from the buffer while the producing unit can be stopped for maintenance without affecting delivery continuity.
2Ease of repair
If the producing unit is stopped for replacement or repair of broken elements, then maintenance can be performed, but the supply of UFB-containing liquid is intermitted
Solution Approach 1:
The buffer tank accumulates UFB-containing liquid in advance during normal operation, creating a reserve that can be used when the producing unit stops operating. This preliminary accumulation ensures that the liquid delivering unit can continue delivering accumulated liquid even when the producing unit is stopped for maintenance or repair.
Solution Approach 2:
The system maintains continuous useful action by separating the delivery function from the production function. The liquid delivering unit continues to deliver liquid from the buffer tank while the producing unit is stopped for maintenance, ensuring that the useful action of liquid delivery continues without interruption.
3Reliability
If a buffer tank is added to accumulate liquid, then continuous delivery is enabled during maintenance, but the device complexity increases
Solution Approach 1:
The buffer tank serves multiple functions: it accumulates UFB-containing liquid during normal operation, provides a reserve for continuous delivery during maintenance, and acts as a decoupling element between production and delivery. This multi-functionality justifies the addition of the buffer tank despite the increased device complexity.

AI summary
The apparatus includes: a producing unit that generates ultrafine bubbles in a liquid supplied from a liquid introducing unit to produce an ultrafine bubble-containing liquid containing the ultrafine bubbles, and delivers the ultrafine bubble-containing liquid; a liquid delivering unit that delivers the ultrafine bubble-containing liquid to an outside; a buffer tank that receives the liquid delivered from the producing unit and delivers the liquid to the liquid delivering unit; and a controller that controls the delivery of the ultrafine bubble-containing liquid from the buffer tank to the liquid delivering unit such that, if the producing unit stops operating, an ultrafine bubble-containing liquid accumulated in the buffer tank is delivered to the liquid delivering unit to enable the liquid delivering unit to deliver the ultrafine bubble-containing liquid to the outside.
