Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fine bubble generation means is used in hard water storage unit, then metal ions are removed from hard water, but removing effect of metal ions is insufficient
Solution Approach 1:
The patent changes the physical parameters of bubbles from conventional large bubbles to fine bubbles with diameter of 100 μm or less, and further to ultrafine bubbles with diameter of 1 μm or less. This parameter change in bubble size dramatically increases the surface area for adsorption, thereby improving metal ion removal efficiency while ensuring sufficient removal effect
Solution Approach 2:
The patent transitions from conventional bubble generation to fine bubble and ultrafine bubble generation, representing a dimensional change in the scale of bubbles. This dimensional transition from millimeter/micrometer scale to sub-micrometer/nanometer scale enables significantly enhanced adsorption capacity and removal effectiveness for metal ions
2Reliability
If fine bubbles are used to adsorb metal ions, then metal ion removal is achieved, but there is room for improvement in enhancing removing effect
Solution Approach 1:
The patent replaces conventional mechanical bubble generation methods with specialized fine bubble and ultrafine bubble generation means. This substitution enables the creation of bubbles with dramatically reduced diameter (100 μm or less, preferably 1 μm or less), which provides vastly increased surface area for metal ion adsorption, thereby simultaneously achieving high reliability and high productivity in metal ion removal

AI summary
An ion removal system includes: an electrolysis device configured to generate alkaline water and acid water by electrolysis; a hard water flow path to supply the electrolysis device with hard water; a first flow path and a second flow path through which the alkaline water and the acid water generated by the electrolysis device can alternately flow; a fine bubble generation device configured to generate and supply fine bubbles to the hard water flow path, the first flow path, or the second flow path so as to adsorb and remove metal ions in water by the fine bubbles generated; and a controller, wherein the controller controls the electrolysis device to perform a first mode in which the alkaline water is allowed to flow through the first flow path and the acid water is allowed to flow through the second flow path and a second mode in which the acid water is allowed to flow through the first flow path and the alkaline water is allowed to flow through the second flow path.
