Substrate-Backed Porcelain Structure for Fracture-Resistant Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Porcelain sheets are prone to fracturing during transportation, installation, and use due to their heavy and brittle nature, leading to safety risks and increased costs, and they require precise cutting at the factory to avoid fractures on-site.
Innovation Solution
A substrate is secured to the backside of porcelain sheets to stabilize and reinforce them, allowing for easier handling, cutting, and installation, reducing the risk of fracture and enabling larger sizes without additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If porcelain sheets are made thinner to reduce weight, then weight decreases and ease of handling improves, but fracture resistance deteriorates
Solution Approach 1:
The patent combines porcelain with a substrate material to create a composite structure. The substrate acts as a reinforcing backbone that provides structural support and fracture resistance, allowing the porcelain layer to be made thinner without compromising overall strength. This composite approach resolves the contradiction by distributing mechanical loads between the two materials.
Solution Approach 2:
The porcelain layer is positioned on top of the substrate, creating a nested structure where the substrate provides the structural framework and the porcelain provides the functional surface layer. This nested arrangement allows the thinner porcelain to benefit from the substrate's structural support during handling and installation.
2Productivity
If porcelain sheets are made larger to cover surfaces more efficiently, then installation time decreases and coverage improves, but fracture risk increases due to greater self-weight and stress
Solution Approach 1:
The substrate provides a rigid structural framework that supports large spans of porcelain without excessive deflection. This composite structure enables larger sheet sizes to be used confidently, as the substrate bears much of the self-weight and reduces bending stresses in the porcelain layer.
Solution Approach 2:
The substrate adds structural dimensionality to the porcelain assembly, creating a sandwich structure that distributes loads across multiple planes. This dimensional reinforcement allows larger panels to maintain adequate stiffness and strength despite increased size.
3Strength
If thicker porcelain sheets are used to improve fracture resistance, then strength increases, but weight increases and cost increases
Solution Approach 1:
The substrate takes on the primary structural role of providing fracture resistance and rigidity, which allows the porcelain layer to be made thinner than it would need to be if standing alone. This material assignment optimization reduces overall weight while maintaining required strength levels.

Function Achieved in This Case
The addition of a substrate improves porcelain's resistance to fracture, enabling thinner, lighter sheets that are easier to transport and install, allowing on-site resizing and cutting, and reducing the need for underlayment, thus enhancing usability and safety.
Implementation Method 1
coating a surface of the porcelain with adhesive, coating a surface of the substrate with adhesive, and stacking the porcelain and the substrate so that the surface of the porcelain faces the surface of the substrate
