Design for Manufacturability

Food Processor Redesign

The food processor is a common appliance found in most kitchens across the country, but there are many improvements that can decrease the consumer cost as well as increase the functionality of this particular product. The assembly time and cost was decreased by making use of snap fits. The screws for the bottom were replaced with snap fits and the motor casing will snap fit into the base while the motor casing holder will be molded into the base, which eliminates an unnecessary part. For functionality improvements, the original two blades were increased to three which are longer and thicker than the original. The new blades increase the processing efficiency of the product. The lid locking mechanism was redesigned similar to a flexible blender top, which will make it easier for the user to seal. Additionally the lid can be attached at any orientation while still activating the lid locking mechanism. The new lid locking mechanism will use a compliant actuator rather than a spring mechanism, which reduces the number of parts and assembly time. The bowl handle will fall on the side of the food processor, rather than in front of the controls, so it will not impede operation of the food processor. Finally, the two separate control buttons are combined using a single flip-switch. This redesign was developed by Erin Cooke, Allison Gasperut, Maureen Heintz, and Beejal Patel in Winter 2005, instructors: Prof. Sridhar Kota, Mentor Dr. Donald Malen, and Teaching Assistant Audrey Plinta.
