Composite Resin Dishware Structure for Durable Non-Slip Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crockery materials like porcelain, ceramic, wood, and earthenware are fragile, prone to chipping, difficult to clean, and not customizable, while alternative materials like plastic are complex to manufacture and maintain, and often used in non-food decorative objects that can be hazardous.
Innovation Solution
A composite dishware element made of food-grade epoxy resin or polymethyl methacrylate with a non-slip surface, featuring a thick upper layer and a thin lower layer, allowing for customization and enhanced durability through a simplified manufacturing process involving layering and polymerization of epoxy resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional materials like porcelain, ceramic, wood, or earthenware are used for crockery, then the material provides traditional aesthetic and functional properties, but the material becomes fragile and prone to chipping after repeated use
Solution Approach 1:
The patent applies composite materials by combining a transparent or translucent rigid layer (polymethyl methacrylate or epoxy resin) with an opaque colored layer (epoxy resin with pigments). This composite structure creates a dishware element that is both durable and resistant to shocks, eliminating the fragility issue of traditional materials while maintaining aesthetic appeal through the layered optical effects.
2Ease of operation
If traditional crockery materials are used, then the material provides structural integrity, but the material becomes difficult to clean and maintain
Solution Approach 1:
The patent uses homogeneous polymer and resin materials that create a non-porous, uniform surface throughout the dishware structure. This homogeneity prevents food and stain penetration, making the dishware easy to clean and maintain while preserving structural integrity through the bonded layered construction.
3Adaptability or versatility
If traditional materials are used for crockery, then the material provides natural appearance, but the material does not allow for easy customization of design
Solution Approach 1:
The patent segments the dishware into distinct functional layers: a transparent/translucent structural layer and an opaque colored decorative layer. This segmentation allows independent optimization of each layer's properties and enables easy customization of the colored layer through various pigments and patterns without complicating the manufacturing process, as each layer can be prepared and bonded separately.
4Strength
If plastic materials are used for crockery, then the material becomes less fragile, but the manufacturing and assembly process becomes complex
Solution Approach 1:
The patent merges multiple functions into a single bonded structure where the transparent layer and opaque layer are permanently joined through adhesive bonding. This merging eliminates the need for separate attachment mechanisms, screws, or complex assembly processes, thereby reducing structural complexity while maintaining the shock resistance benefits of plastic materials.
5Weight of stationary object
If decorative objects are made with traditional materials, then the object provides structural stability, but the object becomes heavy and unattractive
Solution Approach 1:
The patent uses composite materials where the transparent or translucent rigid layer provides structural stability with low weight, while the opaque colored layer adds aesthetic appeal. This composite approach creates lightweight decorative objects that maintain structural integrity, eliminating the heaviness associated with traditional materials like porcelain and ceramic.

Function Achieved in This Case
The solution provides a non-toxic, resistant, and customizable dishware with a unique visual effect, improved grip, and enhanced durability, addressing the limitations of traditional materials and manufacturing complexities.
Implementation Method 1
allow the layer of epoxy resin to polymerize until you obtain a one-piece element formed of a rigid layer of epoxy resin welded to the rigid plate
Implementation Method 2
To create a lift effect, the top layer may have a refractive index of between 1.3 and 1.6
Implementation Method 3
the abrasion operation can be a sandblasting operation carried out by microbeading

AI summary
The invention relates to an item of dishware for containing foodstuffs, said item being formed from two rigid layers: a first, upper layer (10) having a surface (100) comprising one or more hollow forms (101) for receiving and retaining the foodstuffs, and a second, lower layer (11) having an underside (110) forming a base, said item of dishware being characterized in that: • - the first layer (10) has a thickness greater than or equal to 3 mm and consists substantially of food-grade epoxy resin or of food-grade polymethyl methacrylate, said resin or said methacrylate being colourless and translucent; • - the second layer (11) has a thickness greater than or equal to 1 mm, remaining less than that of the first layer (10), and consists substantially of opaque epoxy resin; • - the two layers (10, 11) are fused together so as to obtain a one-piece item.
