The material selection and structure of anti-drop tableware

Material selection and structural design of anti-drop tableware

The core of anti-drop tableware lies in enhancing its impact resistance through material optimization and structural innovation. The following analysis will be conducted from three aspects: material characteristics, structural design, and typical cases:

First, material selection

High-strength ceramic materials

Nanoceramics: Utilizing a composite substrate of zirconia and alumina, nanoscale particles form a honeycomb-like crystal structure with a density of up to 6.0g/cm³, and the grain boundary binding energy is enhanced to 2000MPa. When subjected to external force impact, tiny displacements occur between nanoparticles to disperse stress and prevent stress concentration from causing overall rupture.

Tempered glass: A compressive stress layer is formed on the surface of the glass through an ion exchange process. For instance, after heating the glass, it is immersed in a potassium nitrate solution, allowing potassium ions to replace sodium ions and enter the glass structure, thereby enhancing its impact resistance.

Metals and Alloys

Stainless steel: 304 or 316 stainless steel has high strength and corrosion resistance, but it should be kept away from acidic or high-salt foods. The drop resistance can be enhanced by thickening the wall body or designing reinforcing ribs.

Titanium alloy: It has low density and high strength, but is relatively expensive. It is suitable for high-end anti-drop tableware.

Polymer composite material

Melamine resin: It is formed by the condensation polymerization of melamine and formaldehyde. It has a compact structure, high hardness, and better drop resistance than ordinary plastics. However, it should be avoided to come into contact with high temperatures for a long time.

Fiberglass reinforced plastic (FRP) : It is composed of glass fibers and resin matrix, featuring high strength and good toughness, but its surface is prone to wear.

Recyclable and environmentally friendly materials

Recycled glass: Mix recycled glass with new raw materials and enhance its strength through high-temperature melting and a three-layer glass structure.

Plant-based materials: such as corn starch-based plastics, are degradable but have relatively low strength and need to be reinforced by adding fibers.

Second, structural design

Multi-layer composite structure

Three-layer glass design: The outer and inner layers are ordinary glass, and the middle layer is elastic resin, which is combined through co-extrusion molding process to absorb impact energy.

Metal-ceramic composite: The inner layer is ceramic and the outer layer is a metal shell. They are combined through hot pressing, featuring both aesthetic appeal and shock resistance.

Energy absorption structure

Honeycomb support: Honeycomb structures are designed at the bottom or side walls of tableware to absorb impact energy through the deformation of honeycomb units.

Corrugated wall body: Corrugated protrusions are set on the side walls of the tableware to enhance structural rigidity and energy absorption capacity.

Buffer and protection design

Silicone sleeve: Wrap a silicone sleeve around the outside of the tableware to absorb impact energy through the elastic deformation of silicone.

Suction cup base: Suction cups are designed at the bottom of the tableware and fixed to the tabletop to prevent toppling over.

Edge and corner reinforcement

Thickened edges: Increase the thickness of the edges of tableware to enhance their impact resistance.

Rounded corner design: The corners of the tableware are designed to be rounded to avoid stress concentration.

Third, analysis of typical cases

Shock-resistant ceramic tableware

Material: A composite ceramic of zirconia and alumina is adopted, with a density of 6.0g/cm³ and a Mohs hardness of 8.5.

Structure: The bowl body is designed with a double-layer structure. The inner layer is made of ceramic, the outer layer is a silicone sleeve, and the bottom is thickened and equipped with suction cups.

Performance: In the free drop test from a height of 1.5 meters, the integrity rate was 100%. In the thermal shock stability test, there were no cracks after 50 water bath cycles from 200℃ to 0℃ with a sudden drop.

Three-layer glass dinner plate

Material: The outer and inner layers are ordinary glass, and the middle layer is elastic resin.

Structure: The three layers of materials are combined through co-extrusion molding process, and the edges are designed in a wavy shape.

Performance: The impact resistance is three times higher than that of ordinary glass and can withstand a drop test from a height of 80cm.

Stainless steel - silicone composite tableware

Material: The inner layer is 304 stainless steel and the outer layer is food-grade silicone.

Structure: The silicone layer is combined with the stainless steel layer through clips, and the bottom is designed with thickened rounded corners.

Performance: Excellent drop resistance and also has anti-scald function.
