Tableware Plastic Dipping Layer for Anti-Slip and Heat Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tableware materials such as ceramic, glass, and stainless-steel are not slip-resistant, heat-resistant, and require cumbersome processes with high production costs due to pressing rubber material onto the bottom, leading to increased costs.
Innovation Solution
A dipping process is applied to the bowl bottom and bowl seat of the tableware, using a plastic dipping layer made of natural rubber PVC, TPU, or silicone rubber, which provides low thermal conductivity and high friction coefficient, enhancing anti-scalding and anti-slip properties, and is produced through a simpler method without expensive mechanical equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional materials (ceramic, glass, stainless-steel) are used for tableware, then durability and hygiene are improved, but anti-slip and heat resistance properties deteriorate
Solution Approach 1:
The patent applies a rubber material layer on the bottom surface of the tableware, creating a composite structure that combines the advantages of traditional materials (durability, hygiene) with the advantages of rubber material (anti-slip, heat resistance). This composite approach resolves the contradiction by integrating two different material systems to achieve multiple functional benefits simultaneously.
2Object-affected harmful factors
If rubber material is pressed onto the bottom of tableware using specific pressing equipment, then anti-slip and heat resistance properties are improved, but manufacturing complexity and production cost increase
Solution Approach 1:
The patent integrates the rubber material layer directly into the tableware manufacturing process, combining the tableware body formation and rubber material application into a single integrated process. This eliminates the need for separate pressing equipment and multiple processing steps, thereby reducing manufacturing complexity while maintaining the anti-slip and heat resistance properties.
3Object-affected harmful factors
If rubber material is pressed onto the bottom of tableware using specific pressing equipment, then anti-slip and heat resistance properties are improved, but production cost increases
Solution Approach 1:
The patent combines the rubber material application step with the tableware manufacturing process, eliminating the need for separate pressing equipment and additional production steps. This integration reduces equipment investment and operational costs while maintaining the desired anti-slip and heat resistance properties, thereby improving ease of manufacture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The plastic dipping layer achieves anti-scalding and anti-slip effects while reducing production costs by simplifying the manufacturing process and improving material properties.
Implementation Method 1
The plastic dipping layer has characteristics of low thermal conductivity and high friction coefficient, which can hinder heat conduction of the bowl body
Implementation Method 2
When the plastic dipping layer encounters a tabletop or palm, it can generate a large frictional force
