Solution Overview

Problem

Current ion separation methods in aqueous solutions are inefficient, as they often require sequential processing, entrap ions rather than purging them, and struggle to differentiate between metallic and nonmetallic ions, leading to suboptimal purification and energy consumption.

Innovation Solution

The use of a deionization chamber with a sinusoidal network of finite differences, where electrodes are operated with alternating electrical currents to accelerate ions exponentially, allowing for parallel processing and efficient separation of ions based on electrical forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional ion-exchange methods are used, then ion separation can be achieved, but the process requires sequential processing and entangles ions rather than purging them efficiently

Engineering Contradiction:

Improveion separation rateVSAvoidprocessing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system divides the ion separation process into multiple independent electrode zones arranged in series, where each zone handles specific ion removal tasks. This segmentation enables parallel processing of different ion types simultaneously across multiple zones, eliminating the sequential bottleneck of traditional ion-exchange methods and achieving exponential separation rates.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using ion-exchange resins that entrap ions through adsorption, the patent inverts the approach by using electrochemical reactions at electrode surfaces to directly convert and purge ions from the solution. This inversion transforms the separation mechanism from entrapment-based to conversion-based, dramatically improving processing efficiency and enabling parallel operation.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If conventional desalination methods are employed, then water purification is achieved, but high energy consumption is required

Engineering Contradiction:

Improvepurification qualityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces mechanical/thermal desalination processes (such as reverse osmosis or distillation) with an electrochemical system using electrode arrays. This substitution utilizes electrical energy to drive direct ion conversion reactions, which consume significantly less energy than the high-pressure or high-temperature processes required by conventional methods, while maintaining high purification quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the operational parameters by applying controlled electrical potentials to electrode surfaces, enabling ion removal through electrochemical reactions rather than mechanical forcing. This parameter change from mechanical/thermal to electrical control allows for lower energy consumption while achieving reliable water purification.

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If ion-exchange resins are used, then ion binding occurs, but the ligand undergoes undesirable physical transformation such as denaturation

Engineering Contradiction:

Improveion separation selectivityVSAvoidphysical transformation of ligand

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the chemical adsorption mechanism of ion-exchange resins with electrochemical conversion at electrode surfaces. This substitution eliminates the need for ligand binding and subsequent desorption steps that cause physical transformation and denaturation. Ions are directly converted at the electrode interface, preserving the integrity of any associated ligands or biomolecules.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electrode surface acts as an intermediary that facilitates ion removal through surface reactions without requiring bulk solution binding. This intermediary mechanism allows for selective ion removal through controlled electrochemical reactions, avoiding the harsh binding conditions of ion-exchange resins that cause ligand denaturation.

Inventive Principle:

Principle #24Intermediary (Mediator)
