Innovation Solution
A fine bubble generation apparatus that uses an electrolysis bath with an anode and cathode plate to charge water positively, combined with a mixing tank and nozzles to generate fine bubbles, which are then used in a water treatment system with ultrasound waves to sterilize and disinfect germs, eliminating the need for chemical agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fine bubble generation apparatuses use negatively charged bubbles for water treatment, then the apparatus structure is simple, but particle removal efficiency deteriorates and excessive pretreatment is required
Solution Approach 1:
The patent changes the electrostatic parameter of bubbles from negative charge to positive charge through electrolysis. This parameter change enables positive bubbles to attract negative particles effectively, resolving the inefficiency of negative-negative repulsion while maintaining apparatus simplicity
Solution Approach 2:
The patent replaces chemical agents (surface absorbents) with an electrostatic field generated by electrolysis to achieve particle attachment. This substitution eliminates chemical contamination risks while improving particle removal efficiency through electrostatic attraction
2Productivity
If chemical agents such as surface absorbents are used to produce positively charged bubbles, then particle removal efficiency improves, but water contamination occurs and safety deteriorates
Solution Approach 1:
The patent replaces chemical agents with an electrostatic field generated by electrolysis. This substitution produces positive bubbles without introducing chemical contaminants, eliminating water contamination risks while maintaining particle removal efficiency
Solution Approach 2:
The system uses electrolysis of water itself to generate positive bubbles, making the water treatment process self-sufficient without external chemical agents. The water is electrolyzed to produce positive bubbles that then treat the water, creating a closed-loop system without contamination
3Force
If conventional negatively charged bubbles are used, then no additional charging equipment is needed, but attractive force with foreign matter deteriorates
Solution Approach 1:
The patent changes the electrostatic charge parameter from negative to positive through electrolysis, enabling attractive force between positive bubbles and negative particles. This parameter change provides the necessary attractive force while using only simple electrolysis equipment
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
The apparatus generates a large amount of positively charged fine bubbles that effectively attract and sterilize negatively charged foreign matter, reducing treatment costs and preventing water contamination, while ensuring efficient germ removal without chemical agents.
Implementation Method 1
an electrolysis bath having an anode plate and a cathode plate in an interior space, into which a predetermined amount of treated water is supplied, to electrolyze the treated water
Implementation Method 2
a mixing tank, to which the electrolyzed treated water is supplied in a pressurized state by a pump disposed at an intermediate portion of a water feeding pipe extending from the electrolysis bath, and to which air supplied through an air inflow control valve is supplied, the mixing tank being provided therein with a plurality of interior nozzles through which the treated water mixed with the air passes to form fine bubbles
Implementation Method 3
an ultrasonic oscillator generating ultrasound waves having a predetermined intensity upon application of electric power such that the fine bubbles supplied into the treatment container and floating towards a water surface explode
Implementation Method 4
when such fine bubbles having an ivory color contract and extinguish in water through continuous explosion while ascending at a very slow speed, impact waves including ultrasound waves of 40 kHz are generated and propagate at a speed of 400 km per hour

AI summary
Provided is a water treatment apparatus using an apparatus for generating fine bubbles having a positive charge. The water treatment apparatus comprises: an apparatus for generating fine bubbles having a positive charge; a treatment bath into which the fine bubbles generated in the apparatus for generating fine bubbles are supplied and in which raw water is stored; and an ultrasonic oscillator for generating ultrasonic waves having a predetermined intensity when power is applied to explode the fine bubbles floating up to a water level after the fine bubbles are supplied into said treatment bath. Thus, germs attached to the fine bubbles may be sterilized by an exploding force generated when the fine bubbles are exploded.
