There has been increased recognition of the need for innovation in emergency sanitation products and technologies. To support effective design, this paper explores an approach systematically innovate by framing the problem from the perspective of the functions (the desired outcomes of a design) that features (characteristics of a design) achieve. The paper illustrates examples of how such functions can be identified: by analysing existing designs, studying the literature and drawing lessons learned from case studies. Functions may be interrelated and vary in nature and importance in different circumstances. Functions can be achieved by implementing one or more design features. At the same time, features can contribute to achieving one or more functions. By understanding and consolidating all possible functions and features, this approach can support innovation in several ways, most fundamentally by ensuring that important design considerations are not overlooked during the product development process.
