Integrating Technology and Craftsmanship to Develop a Thai Fruit Carving Knife Using Design Thinking

Abstract

This study aimed to develop the design model of a fruit carving knife which has desirable properties based on the needs of Thai skilled carvers by using design thinking that integrates aesthetics, functionality, and cultural identity. The study utilized a mixed methods research technique. Initially, 40 fruit carving experts were interviewed in-depth about the use of fruit carving knives, with data evaluated through content analysis to define user needs and design criteria. Guided by the design thinking stages of empathize, define, ideate, and prototype, a knife design model was developed, featuring the following physical and functional aspects of blade and grip: 1) a 50 mm straight blade with a cutting angle of 17-30 degrees made of high-carbon steel for maintaining sharpness and rust resistance, and 2) a round lightweight grip made of aluminum decorated with contemporary Thai patterns using laser techniques. User satisfaction with the developed design model was evaluated by 80 participants using a structured questionnaire. The results indicated high levels of satisfaction across blade performance, grip ergonomics, and aesthetic design, with overall satisfaction rated at a very high level. The findings demonstrate that the design thinking process is effective for developing craft tools that respond to user needs while supporting cultural preservation and practical use in both professional and educational contexts.
