Design of an Automatic Grinding Machine for the Bottom of Ceramic Plates based on TRIZ Theory

To address the issue of high labor intensity and potential hand injury associated with manual grinding of the bottom of ceramic plates, an automatic bottom grinding machine for ceramic plates was designed using the TRIZ theory product design process. Demand analysis was conducted to obtain the composition and function decomposition model of each mechanism of the machine. TRIZ theory's contradiction matrix, "HOW TO" model, and physical field analysis methods were then utilized to analyze the design problems and identify solutions. The resulting automatic bottom grinding machine can automatically feed a ceramic plate into the grinding station, apply pressure and grind the plate bottom automatically, and then return the ceramic plate to the initial station. This machine eliminates the need for manual pressing and grinding, mitigating the risk of operator injury. The successful application of TRIZ theory in the development of this mechanical equipment demonstrates its effectiveness as a practical method for designing new products and upgrading old equipment.
