Solution Overview

Problem

Existing methods for forming mosaic panels using PVC points are inefficient due to high energy consumption, complex machinery, and suboptimal adhesion, particularly with water-based glues and large curing ovens, which result in increased costs and labor, and often lead to misalignment and quality issues.

Innovation Solution

A system utilizing an elastic silicone grid with cells to hold tiles and a Teflon-coated plate with strategically positioned holes for PVC glue points, combined with a movable glue distribution head for precise glue application and infrared drying, reduces energy consumption and ensures accurate alignment and adhesion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional curing ovens are used to harden PVC points at 180°C for 15 minutes, then adhesion strength is improved, but energy consumption and cycle time increase significantly

Engineering Contradiction:

Function Achieved in This Case

This approach simplifies the production process, reduces energy consumption, and ensures high-quality, accurately aligned mosaic panels with improved adhesion and reduced labor, while maintaining affordability and speed.

Implementation Method 1

the glue points are applied at the base of the tiles lying with the back face on a layer of Teflon®-coated material (to prevent adhesions). The plasticised PVC has a substantially liquid consistency at the application temperature (room temperature) and must be hardened by heating.
