Solution Overview

Problem

Conventional ceramic non-stick coatings for cookware and other applications face challenges in maintaining durability and non-stick properties over time, particularly under heat exposure and abrasion, leading to degradation and loss of structural integrity.

Innovation Solution

An enhanced ceramic coating composition incorporating 0.2 wt %-2 wt % diamond additive, combined with a non-stick ceramic coating composition, which includes silica or zirconia, and a sol-gel formulation with specific binder, silica, and far-infrared radiation-emitting ceramic powder, significantly enhances non-stick durability, scratch resistance, and thermal conductivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional ceramic non-stick coatings are used, then the coating provides initial non-stick properties, but the non-stick durability is lost quickly over time due to heat and abrasion

Engineering Contradiction:

Improvenon-stick durabilityVSAvoidservice life of non-stick property

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies composite materials by combining ceramic coating composition with diamond particles (0.1-2 wt%) to create an enhanced ceramic coating. This composite structure integrates the non-stick properties of ceramic with the extreme hardness and thermal stability of diamond, resolving the contradiction between initial non-stick performance and long-term durability under heat and abrasion conditions

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent changes the chemical composition parameters of the coating by incorporating specific amounts of diamond particles (0.1-2 wt%) into the ceramic coating formulation. This parameter modification transforms the coating's physical and chemical properties, enhancing its resistance to degradation from heat exposure and mechanical abrasion while maintaining non-stick functionality

Inventive Principle:

2Reliability

If silicone oil is added to sol gel to improve non-stick properties, then initial non-stick effect is enhanced, but the benefit is temporary and properties are lost quickly

Engineering Contradiction:

Improvenon-stick propertyVSAvoidduration of non-stick effect

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent changes the compositional parameters by replacing or supplementing silicone oil with diamond particles (0.1-2 wt%) in the sol gel system. This parameter change transforms the temporary non-stick effect provided by silicone oil into a permanent enhancement through the incorporation of thermally stable and abrasion-resistant diamond particles that maintain non-stick properties over extended service life

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent addresses the temporary nature of silicone oil-based non-stick properties by introducing diamond-reinforced ceramic particles that provide long-lasting performance. The diamond-enhanced coating replaces the need for frequent reapplication or replacement associated with short-lived silicone oil coatings

Inventive Principle:

Solution Approach 1:

The patent applies composite materials by integrating diamond particles (0.1-2 wt%) into the ceramic coating matrix, creating a multi-functional composite where diamond provides extreme hardness and thermal stability for structural integrity, while the ceramic phase maintains non-stick properties. This composite structure resolves the contradiction by ensuring both structural strength and functional performance are maintained simultaneously under harsh cooking conditions
