Solution Overview

Problem

Nonstick coatings on cookware are prone to scratching and damage from sharp utensils, limiting their durability and cross-use, and they often fail to prevent food from sticking effectively, especially on heated surfaces.

Innovation Solution

A cookware surface design featuring a base material layer with embedded mesh layers and a nonstick coating, where the mesh segments extend beyond the nonstick coating to create a protective barrier against utensils and enhance food release, using materials like aluminum and stainless steel for the base and mesh layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a nonstick coating layer is applied to the cookware surface, then food release is improved, but the coating becomes susceptible to scratching and damage from utensils

Engineering Contradiction:

Improvefood releaseVSAvoidcoating durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The surface is segmented into multiple functional layers: a base material layer, a nonstick coating layer, and a protective mesh layer with network segments. The mesh layer is divided into discrete segments that extend beyond the nonstick coating, creating a protective barrier while leaving the nonstick coating exposed in interior regions for food release.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cookware surface combines multiple materials with different properties: a base material (e.g., aluminum) for thermal conductivity, a nonstick coating (e.g., PTFE) for food release, and a protective mesh layer (e.g., stainless steel) for durability and cut resistance. This composite structure resolves the contradiction by assigning different functions to different materials.

Inventive Principle:

Principle #40Composite materials

2Reliability

If the mesh layer provides protection against utensils, then coating durability is improved, but food may stick in the interior regions

Engineering Contradiction:

Improvecoating durabilityVSAvoidfood release

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Different regions of the surface have different properties: the exterior regions have mesh segments extending beyond the nonstick coating for protection, while the interior regions have exposed nonstick coating for food release. This local differentiation resolves the contradiction by providing both protection and nonstick properties in appropriate locations.

Inventive Principle:

Principle #3Local quality

3Strength

If a second mesh layer is added to the opposite side, then structural strength is improved, but device complexity increases

Engineering Contradiction:

Improvestructural strengthVSAvoidlayer structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The second mesh layer on the opposite side serves multiple functions: it provides structural strength, acts as an induction heating feature, and offers protection against damage from the other side. This multi-functionality justifies the additional layer by providing multiple benefits rather than a single function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Cookware surfaces of metal, such as aluminum, may include a nonstick coating and embedded hard metal mesh. The mesh protects the nonstick coating between interior regions within the mesh from being cut or abraded by knives and other tools.
