The principles of Design for Manufacturing and Assembly (DFMA) were applied to the redesign of a manual shredding machine used to harvest breadfruit in the Republic of Haiti. The DFMA methodology examined each function of the shredder assembly to determine if a part could be eliminated or combined with another part and if there were simpler ways to meet the performance criteria without sacrificing quality. A breadfruit shredder designed by a previous senior design group that met the customer

... engineering specifications was subjected to the DFMA process resulting in a machine that was easier to build in a developing country, used materials that were more commonly available, had a reduced number of parts, was more robust, was easier to clean and keep sanitary, and cost less to make.
