Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current desalination systems are inefficient in removing ionic impurities from water, leading to high salinity in desalinated water and increased demand for fresh water due to limited natural sources.
Innovation Solution
A desalination system and method utilizing a separable main container with electrodes or conductors to create electric or magnetic fields, concentrating ions of one charge type in specific regions, allowing for the separation and removal of ions, thereby reducing salinity in one region and concentrating high-salinity ions for discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional desalination systems are used, then water treatment is provided, but ionic impurities are not effectively removed resulting in high salinity
Solution Approach 1:
The main container is divided into multiple regions (first region, second region, third region) separated by fluidic separation mechanisms. This segmentation allows different stages of ion concentration and separation to occur in distinct zones, improving the efficiency of ionic impurity removal while maintaining system reliability.
Solution Approach 2:
Electrodes are introduced as intermediary elements that generate electric fields to manipulate ion movement. These electrodes act as mediators between the power source and the ionic impurities, enabling effective separation of ions from water without direct mechanical contact, thus improving removal efficiency while preserving water quality.
2Quantity of substance
If natural fresh water sources are relied upon, then fresh water supply is maintained, but sources are limited and cannot meet increasing demand
Solution Approach 1:
The system enables salt water to be converted into fresh water through self-contained electrochemical processing. The desalination system serves itself by using electric fields to automatically separate ions from water, transforming abundant salt water into usable fresh water and eliminating dependence on limited natural fresh water sources.
3Manufacturing precision
If ion concentration is increased in one region, then salinity is reduced in another region, but complex fluidic separation mechanisms are required
Solution Approach 1:
The fluidic separation mechanisms are designed to be dynamically controllable, allowing the system to adapt the separation process based on real-time conditions. This dynamic control enables precise ion concentration management in different regions while keeping the mechanical complexity manageable through automated adjustment rather than fixed complex structures.
