DIY Diabetes

modular learning tool for newly diagnosed diabetes patients

The purpose of this project was to design and manufacture diabetes kits and instructional materials to train newly diagnosed diabetes patients and their caretakers to treat diabetes at home.

A previous team had designed a kit with instructional materials and manufactured 5 of these kits. In this phase of the project, we were tasked with improving that existing design and manufacturing 30 kits to be used in a clinical study.

Requirements & Constraints

Design Development

Using my packaging experience from my time at Webb deVlam, I came up with a few dieline designs.

I came up with a standard assembly procedure for the box and adapted fabrication methods within the capabilities of Northwestern's Ford Prototyping Shop. Instead of using a CAD cutting table (traditionally used in packaging), paper and chipboard were cut on the CO2 laser cutter. Since we didn't have a machine to apply adhesive to the paper, this step was performed by hand.

Since we needed to manufacture 30 kits and each kit is comprised of 4 boxes (1 box for each step), we needed to fabricate a total of 120 boxes. I worked on this project with 2 other interns, and after teaching them my method for fabrication, we were able to construct all 120 boxes within a few weeks - including vac-formed inserts and instructional materials.

Final Design

The final kit design is comprised of 4 boxes that stack magnetically. The boxes close via a magnet flap and a velcro carrying strap allows for easy transport. The magnets allow for a sophisticated presentation and satisfying tactile feedback when the boxes are properly secured and closed.

KEY DESIGN FEATURES

  • 2-layer, paper living hinge is meant to hold up against repeated use
  • Laminate coating on the paper allows the boxes to be cleaned with disinfecting wipes
  • Magnets are strong enough to keep the kit secure while being weak enough that patients with limited strength do not struggle
  • Magnets ensure accuracy and consistency with repeated disassembly/assembly of the kit during use
