Solution Overview

Problem

Existing electrolyzed liquid generators face issues with scale accumulation due to pH changes during ozone generation, which can compress and deform the housing and electrolytic parts, leading to pressure and reduced efficiency.

Innovation Solution

The design incorporates a housing with a channel system and electrolytic part configuration where grooves on the conductive film and electrodes are exposed, allowing for a space between the electrodes and housing to prevent water stagnation and scale accumulation, featuring a stacked body with a conductive film interposed between the anode and cathode, and a channel with inlet and outlet ports for efficient liquid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the electrolytic part is accommodated in a housing with outer periphery in contact with inner surface of housing, then compact structure is achieved, but minute gaps are formed during stacking that allow water to enter and stay, leading to scale accumulation

Engineering Contradiction:

Improvecompactness of electrolytic partVSAvoidscale accumulation in gaps

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the problematic minute gap between the electrolytic part and housing by introducing a resin layer that fills this gap. This prevents water from entering and staying in the gap, thereby eliminating the condition for scale accumulation while maintaining the compact structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a resin layer as an intermediary substance between the electrolytic part and the housing. This resin layer serves multiple functions: it fills the minute gap, prevents water intrusion, and eliminates the harmful effect of scale accumulation without compromising the compact design.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If water is electrolyzed to generate ozone with water staying around the electrolytic part, then ozone generation is achieved, but pH value rises and scale accumulates in the minute gap

Engineering Contradiction:

Improveozone generation efficiencyVSAvoidscale generation from electrolysis

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of water staying in the gap (which causes scale accumulation) into a beneficial outcome by using the resin layer to prevent water intrusion. This allows continuous ozone generation without the harmful side effect of scale formation in the gap.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If scale accumulates in the minute gap around the electrolytic part, then pH changes during electrolysis are not addressed, but the housing and electrolytic part are compressed and deformed

Engineering Contradiction:

Improvestructural stabilityVSAvoidpressure from scale accumulation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by preventing scale accumulation before it can cause compression and deformation. The resin layer fills the gap and prevents water intrusion, thereby preemptively eliminating the source of scale formation that would otherwise compress and deform the housing and electrolytic part.

Inventive Principle:

Principle #9Preliminary anti-action
