Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water softening device is installed to remove ionic substances, then the durability of piping and heat exchangers is improved, but the device complexity and installation cost increase due to requiring replacement of entire piping or water-heating devices
Solution Approach 1:
The water softening function is segmented from the main water-heating device into a separate, modular filter unit. This filter unit can be independently installed in the piping system without replacing the entire water-heating device, thus improving durability while reducing installation complexity
Solution Approach 2:
A separate filter unit acts as an intermediary component between the water source and the water-heating device. This intermediary handles the ion removal function, allowing the main device to remain unchanged while still achieving the durability benefits of softened water
2Manufacturing precision
If electro-deionization is used to remove ionic substances, then the purity of water is improved, but the energy consumption increases
Solution Approach 1:
The electro-deionization process operates periodically with alternating current that reverses direction, allowing ions to be removed during charging phases and electrodes to be regenerated during discharging phases. This periodic operation maintains high water purity while reducing overall energy consumption compared to continuous direct current operation
Solution Approach 2:
The system changes the electrical parameter (current direction) periodically to achieve both ion removal and electrode regeneration. By varying the electrical parameters in a cyclic manner, the system maintains purification effectiveness while improving energy efficiency

AI summary
An ion removal kit according to the present invention comprises: a kit case; a filter unit, which is provided inside the kit case, receives raw water from a main flow path for supplying the raw water to a water-requiring place so as to remove, through electrodeionization, at least some of ionic substances included in the received raw water, thereby discharging soft water containing less ionic substances than raw water; a filter flow path which is provided inside the kit case; and a control part which is provided inside the kit case and which controls the filter unit.
