ZOLL AED Redesign
Sudden cardiac arrest is a time-sensitive emergency. While the ZOLL AED 3 is a powerful tool for bystanders to intervene, there's always room for improvement. This case study explores a redesign of the ZOLL AED 3, focusing on enhancing user experience, accessibility, and effectiveness in critical situations.
For an Industrial Design course, we were tasked with redesigning the ZOLL AED 3. This device provides life-saving care in emergency situations and it is imperative that it is easy to use for all types of users. The current interface provides thorough, easy to understand CPR coaching but the actual layout of the device touch points is cluttered and confusing. I started the redesign process by first analyzing the ZOLL AED and conducting market research, then I started sketching a new layout.

Problem
Self Test/Status indicator is confusing
Small handle is not ergonomic

Display window is small, hard to see
Heavy and bulky, hard to maneuver once set up
Process
Product Notes:
Will most likely be used on the floor
Needs to fit inside a wall mount
Child button turns on automatically if Pedi-Pads are plugged in
Status indicator informs user of successful (or not) Self-check of the battery and pads
Might be stored with or without the carrying case, therefore device should be as easy to carry as possible
