| Background In today’s consumer-driven society, where emotional engagement plays a crucial role, coffee culture has expanded into roastery and specialty coffee. While this trend emphasizes personalization, the development of coffee cups that enhance both the taste of coffee and the user’s sensory experience remains limited. This study assumes that the shape, ceramic material, and firing method of coffee cups are intricately linked to enhancing the perception of high-quality coffee. Guided by emotional design principles, prototypes were created using various ceramic soils and production methods. These were evaluated by coffee enthusiasts to explore their impact on the perception of coffee flavor.
Methods As a design methodology for the prototype, the "emotional design theory" advocated by D.A., Normam. Two types of ceramic soils were used: a silk-white porcelain clay (4B) with no iron content and a mixed clay rich in iron. The materials were fired and crafted using a modern electric kiln and a hybrid kiln that combines gas and wood firing techniques. The sensory perception of specialty coffee was subsequently assessed using five distinct types of containers, including a standard ceramic mug for comparison.
Result The shape and structure of coffee cups designed with emotional design principles, as well as the type of ceramic soil and firing method, significantly influenced the sensory characteristics and user experience of the coffee cups. Notably, coffee cups fired in a gas-wood hybrid kiln achieved the highest evaluations across all criteria. This can be attributed to the hybrid firing method, in which the firing temperature is elevated using gas fuel before being finished with traditional wood firing. This process induces unique changes in color, surface texture, and material properties, which in turn enrich the perception of specialty coffee flavors.
Conclusion Design should go beyond mere functionality to encompass the overall user experience. In this context, the prototypes designed with emotional design principles and produced using the modern gas-wood hybrid kiln demonstrated a clear competitive advantage within the landscape of contemporary coffee culture. The gas-wood hybrid kiln employed in this study embodies the philosophy of ‘harmonizing traditional wisdom with modern technology’ and shows great potential for simultaneously addressing the demand for emotional engagement and cultural value in today’s society. |
