Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-stick pans suffer from poor resistance to high temperature, low hardness, poor wear resistance, and a short service life due to issues with fluorine-containing and ceramic coatings, which are prone to scratching, cracking, and thermal expansion.
Innovation Solution
A nanoscale metal ceramic layer formed by extreme high-speed laser cladding and curing, combined with a new nano-ceramic material, is applied to the pan surface, comprising titanium-coated particles and nanocomposite ceramic powder, enhancing hardness and non-stickiness through alternating layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fluorine-containing coating is used to achieve non-stick function, then non-stick performance is improved, but wear resistance deteriorates and coating easily falls off
Solution Approach 1:
The patent applies composite materials by combining fluorine-containing non-stick coating with a ceramic coating layer. The ceramic layer provides wear resistance and structural stability, while the fluorine-containing coating maintains non-stick performance. This composite structure resolves the contradiction between non-stick performance and wear resistance by distributing functions across different material layers.
2Strength
If ceramic coating is used to improve wear resistance, then hardness is improved, but thermal expansion compatibility deteriorates causing cracks
Solution Approach 1:
The patent applies local quality by creating a gradient or interlayer structure between the ceramic coating and the aluminum pan body. This intermediate structure has thermal expansion properties that transition between the ceramic and aluminum, locally adapting to thermal stress and preventing crack propagation while maintaining the hardness benefits of the ceramic coating.
3Ease of operation
If non-stick coating is applied to achieve non-stick function, then ease of operation is improved, but service life deteriorates due to scratching and scraping
Solution Approach 1:
The patent uses composite materials with a multi-layer structure where a hard ceramic layer provides scratch and scrape resistance, while an outer fluorine-containing layer provides non-stick performance. This composite approach ensures that the coating system as a whole maintains both non-stick function and durability against mechanical damage, extending service life.
4Ease of operation
If existing non-stick coating is used, then non-stick function is achieved, but resistance to high temperature deteriorates
Solution Approach 1:
The patent applies local quality by using different materials with complementary properties in different layers. The ceramic layer has high temperature resistance and is positioned to handle thermal stress, while the fluorine-containing coating provides non-stick function at operating temperatures. This layered approach with locally optimized materials allows the coating to withstand high temperatures while maintaining non-stick performance.
