Design Analysis and Production of a Vegetable Slicer

This paper focuses on the design, development, and evaluation of a manual vegetable slicer tailored for both domestic and semi-commercial applications. Traditional slicing methods using knives or basic graters pose significant challenges, including time inefficiency, injury risk, and non-uniform slices. To address these issues, a user-friendly, manually operated vegetable slicer was developed, emphasizing ergonomic design, material durability, slicing efficiency, and safety. The slicer features a stainless-steel blade with adjustable thickness settings, an ergonomic handle, and a food-safe plastic frame with a non-slip base. Through mechanical testing and user trials, the device demonstrated high cutting efficiency (requiring 55–65 N of force for tough vegetables like carrots), consistent torque (~9 Nm), minimal blade wear, and strong user satisfaction, especially in comfort and slice quality. While the slicer proved robust and reliable, recommendations for future enhancement include improved blade sharpening features, additional slicing styles, and weight reduction. The study validates the slicer as a cost-effective, durable, and safe solution that meets the needs of everyday kitchen users and small-scale vegetable vendors.
