Adding Helpful Carrier Devices to Crutches

People using crutches have their hands occupied, which makes it difficult to carry books and other items they want to have handy. Student teams work through the engineering design process as they are challenged to design assistive devices that modify crutches to help people carry things such as books and school supplies. Given a list of constraints, including a device weight limit and minimum load capacity, groups brainstorm ideas and then make detailed plans for their best solutions. They create prototypes and then test for functionality by loading them and using them, making improvements with each iteration. At a concluding design expo, teams present their concepts and demonstrate their final prototype devices.
