Solution Overview

Problem

Existing ultrafine bubble generating apparatuses using ozone water are prone to corrosion, leading to impurities in the generated ozone ultrafine bubbles, which degrades the purity and quality of the ozone ultrafine bubble-contained liquid.

Innovation Solution

The apparatus employs a silicon substrate with enhanced corrosion resistance for the heating element and a stainless steel or borosilicate glass flow channel member to prevent corrosion and maintain the purity of ozone ultrafine bubbles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional materials are used for liquid contact portions in ozone water, then the apparatus structure is simple and cost-effective, but corrosion occurs leading to impurities in the generated ozone ultrafine bubbles

Engineering Contradiction:

Improvepurity of ozone ultrafine bubble-contained liquidVSAvoidmaterial selection complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by selecting corrosion-resistant materials specifically for liquid contact portions (heating element, flow channel member) while other non-contact components can use conventional materials. This targeted approach ensures purity where needed without unnecessarily complicating the entire apparatus.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent employs composite material solutions by combining stainless steel or borosilicate glass for the flow channel member with corrosion-resistant coatings or treatments on the heating element. This use of composite or treated materials provides both corrosion resistance and structural integrity.

Inventive Principle:

Principle #40Composite materials

2Reliability

If corrosion-resistant materials are used for liquid contact portions, then the purity of generated ozone ultrafine bubbles is maintained, but the cost and complexity of the apparatus increases

Engineering Contradiction:

Improvepurity of ozone ultrafine bubble-contained liquidVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By limiting corrosion-resistant materials to only the liquid contact portions (heating element and flow channel member), the patent minimizes manufacturing complexity while ensuring purity where it matters most. Other components can be manufactured using standard, simpler processes.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent considers using disposable or easily replaceable corrosion-resistant components for liquid contact portions, allowing the use of simpler, potentially less durable materials in non-critical areas while maintaining purity in critical areas through periodic replacement rather than permanent installation of complex corrosion-resistant systems throughout.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If metal or organic materials are used in contact with ozone water, then the apparatus is easy to manufacture, but corrosion and deterioration occur causing contamination

Engineering Contradiction:

Improveease of manufacturing liquid contact portionsVSAvoidcorrosion and deterioration

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by treating or selecting materials specifically for liquid contact portions where corrosion occurs, while other parts of the apparatus can use conventional easily-manufactured materials. This localized approach balances ease of manufacture with corrosion resistance where needed.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary protective layer or coating on the heating element and flow channel member that acts as a barrier between the ozone water and the base material. This intermediary layer prevents direct corrosion while allowing the underlying material to remain easily manufacturable.

Inventive Principle:

Principle #24Intermediary (Mediator)
