Metal cutting board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting boards made of wood, plastic, and glass have drawbacks such as wear and tear, bacterial growth, knife damage, noise, and warpage issues, while metal cutting boards face oxidation, odor retention, and knife damage concerns, making them impractical for food processing.
Innovation Solution
A metal cutting board design featuring a first plate body with a uniform thickness, a second plate body around the periphery, and an inclined connecting portion, formed from a metal plate, with a titanium oxide film for antibacterial and anti-sticking properties, and a thickness between 0.5 mm and 2 mm to prevent warpage and maintain flatness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a thicker metal plate is used to manufacture the cutting board, then the cutting board is more resistant to warpage and maintains better flatness, but the cutting board becomes too heavy
Solution Approach 1:
The cutting board is divided into multiple functional zones: a first plate body for cutting operations, a second plate body for stability, and an inclined connecting portion for transition. This segmentation allows each zone to be optimized independently - the first plate body can be thinner for lightness while the second plate body provides additional stability, resolving the contradiction between weight and flatness resistance.
2Weight of moving object
If a thinner metal plate is used to manufacture the cutting board, then the cutting board is lighter, but the flatness of the cutting board is easily affected by warpage
Solution Approach 1:
The cutting board employs a composite metal plate structure with varying thicknesses and configurations. The first plate body and second plate body are connected through an inclined connecting portion, creating a composite structure that distributes stress more effectively and resists warpage while maintaining overall lightness. This composite design allows the thinner overall profile to achieve the stability normally requiring greater thickness.
3Reliability
If conventional metal materials are used for the cutting board, then the cutting board is durable and resistant to bacterial growth, but metal odors can cling to ingredients and knives are more likely to be damaged
Solution Approach 1:
The invention changes the surface parameters of the metal cutting board by applying a coating layer with different surface properties. This coating modifies the surface energy, roughness, and chemical composition to prevent odor retention and reduce metal-to-metal contact, thereby eliminating the harmful effects while preserving the underlying metal's durability and antibacterial properties.

AI summary
A metal cutting board is integrally formed by a metal plate body and includes a first plate body, a second plate body, and an inclined connecting portion. The second plate body is disposed around a periphery of the first plate body, the second plate body and the first plate body are parallel to each other, and the second plate body and the first plate body are positioned on planes of different heights. The inclined connecting portion is circumferentially disposed between the first plate body and the second plate body. The first plate body, the second plate body, and the inclined connecting portion are integrally formed from the metal plate body and are connected to form a shallow tray structure.
