Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a three chamber structure with rigid guide plates is used, then salt in acidic output is minimized, but ion flow is impeded and system efficiency is limited

Engineering Contradiction:
Improvesalt content in acidic outputVSAvoidsystem efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The invention removes the rigid guide plates and intermediate chamber structure from the electrolyzing system. By extracting these obstructive components, the system allows free ion flow between chambers while maintaining separation of acidic and alkaline outputs, thus resolving the contradiction between minimizing salt content and maintaining system efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses separate electrolyzing chambers for acidic and alkaline production with ion-exchange membranes for separation. This segmented approach allows independent optimization of each chamber's ion flow paths, minimizing salt contamination in acidic output while maintaining high efficiency through unobstructed ion movement.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If electrode plates with openings are used, then ion passage is enabled, but electric field consistency is compromised

Engineering Contradiction:
Improveion passage capabilityVSAvoidelectric field consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The invention employs ion-exchange membranes as porous materials that selectively allow ion passage while maintaining continuous electrode surfaces. This resolves the contradiction by enabling ion transport through the membranes without creating openings in the electrodes, thereby preserving electric field consistency.

Inventive Principle:
Principle #31Porous materials

3Device complexity

If a single ion membrane is used, then system complexity is reduced, but salt levels in acidic solution increase leading to scale buildup

Engineering Contradiction:
Improvemembrane structure complexityVSAvoidscale buildup from high salt levels
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The invention divides the electrolyzing system into separate acidic and alkaline chambers with dedicated ion-exchange membranes for each. This segmentation allows independent control of ion flow to each chamber, effectively preventing salt accumulation in the acidic solution while maintaining relatively simple membrane structures.

Inventive Principle:
Principle #1Segmentation

AI summary

An electrolyzing system for electrolyzing a brine solution of water and an alkali salt to produce acidic electrolyzed water and alkaline electrolyzed water is provided. The system includes an internal chamber for receiving the brine solution and two electrolyzer cells immersed in a brine bath. Each electrolyzer cell includes an electrode, at least one ion permeable membrane supported relative to the electrode to define a space communicating between a fresh water supply and a chemical outlet into which brine enters only through the membrane. One of the electrodes is coupled to a positive charging electrical supply and the other to a negative charging electrical supply.
