Four undergraduate engineers collaborated on a design project for Design 384: Interdisciplinary Design Projects. The challenge: develop a solution to improve Jamaica and Haiti’s breadfruit industry.

Breadfruit Peeler

Problem

Breadfruit is a staple food in Haiti and Jamaica, but its tough, stiff exterior and dense, starchy interior make peeling it difficult. People work six-hour days to peel 30 breadfruits each. The process is physically exhausting and even dangerous — resulting in multiple accidental cuts.

The peel is similar to a cantaloupe. Imagine peeling 30 cantaloupes in a day with just a small knife. We wanted to make a peeler that is safer and works faster.Ahren Alexander, Breadfruit Peeler, Co-creator

Solution

Peeling a breadfruit requires two hands: one to turn the fruit and the other to cut it. The team in a Design 384 class created a solution that prevents exhaustion by delegating these steps to two different people. One pedals a bicycle-powered device that spins the fruit. The other holds a blade up to the fruit to peel it as it spins.

Development Process

The team wanted to address four user needs: 

They prototyped several different ideas, including gloves with built-in blades and a pottery wheel to spin the fruit. But the bicycle-powered device stood out. Because Jamaica has a lot of abandoned bicycle parts, materials would not need to be imported. The device also does not require electricity, which can be scarce and unreliable in Jamaica and Haiti.

Current Status

The team traveled to Jamaica over spring break to test their prototype with users.
