User-Centered Design of a Portable Fire Extinguisher

Abstract

This case study documents the process followed to produce an alternative design of a fire extinguisher. The work focuses on how informative data can be gathered for an ethically challenging product scenario through the use of a range of user-centered research methods, including literature review, product evaluation, shadowing study, empathy study, expert interview, focus groups, and simulation equipment. Design improvements as a consequence of this process include reductions in size and weight, refillable cartridges, single-handed operation, intuitive form, minimal cleanup post-use, and better portability.
