Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric heating porcelain tiles lack lightning protection, leakage prevention, and electrostatic prevention, posing safety risks due to their continuous use and close contact with humans without integrated safety settings.
Innovation Solution
The design incorporates a metal plate protective layer connected to a ground wire, with an electric heating film and lightning protective modules, including varistors, to direct excessive current to ground, ensuring electrical safety and protection against damage from impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating film type electric heating porcelain tiles are used for underfloor heating, then heating function is achieved, but lightning protection and electrical safety are lacking
Solution Approach 1:
The patent combines the heating function and lightning protection function into a single integrated tile structure. The metal plate protective layer serves dual purposes: it acts as a grounding element for lightning protection and as a structural component of the tile assembly, thereby improving electrical safety without significantly increasing overall device complexity.
Solution Approach 2:
The metal plate protective layer is designed to perform multiple functions simultaneously: it provides lightning protection by conducting excess current to ground, serves as a protective barrier for the heating film, and acts as an integral structural element of the tile. This multi-functionality resolves the contradiction by achieving enhanced safety without adding separate dedicated components.
2Reliability
If metal plate protective layer and lightning protective modules are added, then lightning protection capability is improved, but device complexity increases
Solution Approach 1:
The lightning protective modules are integrated within the shell structure rather than being separate external components. The metal plate protective layer is embedded within the tile assembly, merging the protection function with the structural design, thereby improving lightning protection capability while minimizing increases in device complexity.
Solution Approach 2:
The lightning protective modules and metal plate protective layer are nested within the existing shell and tile structure. This nesting approach allows the addition of protection functionality without creating a separate, complex external system, thus resolving the contradiction between improved reliability and increased structural complexity.
3Reliability
If grounding connection is implemented, then leakage prevention is improved, but manufacturing complexity increases
Solution Approach 1:
The grounding connection is merged with the metal plate protective layer that is already an integral part of the tile structure. By using the existing metal plate as the grounding element and connecting it to the ground wire, the patent achieves leakage prevention without requiring separate grounding components or complex manufacturing processes.
Solution Approach 2:
The metal plate protective layer serves its own dual purpose: it provides structural protection and simultaneously functions as the grounding element for leakage prevention. This self-service approach eliminates the need for additional dedicated grounding components, thereby improving safety while maintaining ease of manufacture.

Implementation Method 1
the first lightning protective module and the second lightning protective module are individually connected with the metal plate protective layer through conductors (i.e., conducting wires); and the metal plate protective layer is connected with a ground wire through the conductors
Implementation Method 2
an electric heating film heating layer, located in the shell; where the electric heating film heating layer is attached to an end surface of the metal plate protective layer facing away from the porcelain tile layer

AI summary
A lightning protective and heating porcelain tile includes a porcelain tile layer, a shell, a metal plate protective layer, and an electric heating film heating layer. The metal plate protective layer is attached to the inner wall of the porcelain tile layer, and the electric heating film heating layer is attached to the metal plate protective layer. The electric heating film heating layer includes an electric heating film, a first lightning protective module and a second lightning protective module. The hot wire and neutral wire connected to the electric heating film are electrically connected to the first lightning protective module and the second lightning protective module, respectively. The first lightning protective module and the second lightning protective module are electrically connected to the metal plate protective layer individually. The first lightning protective module and the second lightning protective module are made of varistors.
