Solution Overview
Problem
Stainless steel components used in industrial applications face issues with high friction, wear, and cleanability, leading to premature degradation and increased operational costs, especially in environments involving sliding contact and organic materials.
Innovation Solution
A conveyor component with an electrically conductive substrate coated with a thin, transparent or opaque polymer shell, preferably nylon, is used to reduce friction and enhance cleanability, applied through a powder coating process that forms a durable, wear-resistant surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stainless steel is used for conveyor components, then corrosion resistance is improved, but friction increases and cleanability deteriorates
Solution Approach 1:
The patent applies a composite material system consisting of stainless steel substrate combined with polymer coating layers. The stainless steel provides corrosion resistance while the polymer coating (such as polyolefin, polyester, or urethane) provides low friction and improved cleanability, resolving the contradiction between corrosion resistance and ease of cleaning.
Solution Approach 2:
The patent changes the surface properties of stainless steel by applying a polymer coating that alters the coefficient of friction and surface energy. This parameter change transforms the surface from high friction and oil-adhering to low friction and easy-to-clean, while maintaining the underlying corrosion resistance of the stainless steel substrate.
2Reliability
If stainless steel is used for conveyor components, then corrosion resistance is improved, but wear resistance deteriorates
Solution Approach 1:
The patent creates a composite structure where the polymer coating layer provides wear resistance through its inherent durability and low friction properties, while the stainless steel substrate provides corrosion resistance. This composite approach allows each material to contribute its strength to the overall component performance.
Solution Approach 2:
The polymer coating acts as an intermediary layer between the stainless steel substrate and the operating environment. This intermediate layer absorbs the wear and friction, protecting the underlying corrosion-resistant steel from direct contact with abrasive materials and other components.
3Reliability
If stainless steel is used for conveyor components, then corrosion resistance is improved, but service life deteriorates due to black oxide formation
Solution Approach 1:
The polymer coating serves as a protective intermediary layer that prevents direct contact between the stainless steel surface and abrasive materials. This eliminates the mechanical abrasion that causes black oxide formation, thereby extending the service life while maintaining the corrosion resistance benefits of the stainless steel substrate.
Solution Approach 2:
The polymer coating is applied beforehand to create a protective barrier that cushions against wear and abrasion. This preventive measure stops black oxide formation before it can occur, extending the component's service life without compromising the underlying corrosion resistance.
4Ease of operation
If frequent washing is performed to maintain cleanability, then contamination is reduced, but operational cost increases and component life decreases
Solution Approach 1:
The low friction polymer coating surface has inherent easy-clean properties that reduce the frequency and intensity of washing required. The surface structure and composition cause contaminants to slide off more easily, allowing the component to maintain cleanliness with minimal intervention, thereby reducing operational costs and extending service life.

AI summary
A component subjected to wear during use includes a powder coating formed of a polymer selected from the group consisting of a polyamide, polyolefin, polyester, urethane, epoxy, acrylic, and mixtures thereof to provide improved wear resistance, enhanced cleanability, and reduced surface friction. Preferably, the component is for use in conveying product, such as in a conveyor system, and includes: (1) a metal core and a nylon powder coating; or (2) a stainless steel core and a powder coating. Most preferably, the coating is generally clear or translucent so as to give the appearance that the underlying component, which is typically made of metal, is neither coated nor made entirely of a polymer.
