Reconfigurable products can adapt to new and changing customer needs. One potential, high-impact, area for product reconfiguration is in the design of income-generating products for poverty alleviation. Non-reconfigurable income-generating products such as manual irrigation pumps have helped millions of people sustainably escape poverty. However, millions of other impoverished people are unwilling to invest in these relatively costly products because of the high perceived and actual financial risk involved. As a result, these individuals do not benefit from such technologies. Alternatively, when income-generating products are designed to be reconfigurable, the window of affordability can be expanded to attract more individuals, while simultaneously making the product adaptable to the changing customer needs that accompany an increased income. The method provided in this paper significantly reduces the risks associated with purchasing income-generating products while simultaneously allowing the initial purchase to serve as a foundation for future increases in income. The method presented builds on principles of multiobjective optimization and Pareto optimality, by allowing the product to move from one location on the Pareto frontier to another through the addition of modules and reconfiguration. Elements of product family design are applied as each instantiation of the reconfigurable product is considered in the overall design optimization of the product. The design of a modular irrigation pump for developing nations demonstrates the methodology.

Collaborative products are created when physical components from two or more products are temporarily recombined to form another product capable of performing additional tasks. In this paper, a method for designing collaborative products is introduced. The method identifies a set of products capable of being recombined into a collaborative product. These products are then designed to allow for this recombination. Collaborative products are particularly useful in reducing the cost, weight, and size of poverty-alleviating products—reductions that are valued in the developing world. A simple example of a cabinet maker’s tool shows that a collaborative block plane created from a chisel and sanding block can account for reductions in cost, weight, and size of 44%, 38%, and 44% respectively, when compared to a typical wooden block plane, chisel, and sanding block. Additionally, an example of a collaborative apple peeler is provided to demonstrate scalability of the method. The authors conclude that the method introduced herein provides a new and useful tool to design collaborative products and to assist in engineering-based poverty alleviation.

Natural changes in customer needs over time often necessitate the development of new systems that satisfy the new needs. In a previous work by the authors, a 5-step multiobjective optimization-based method was presented to identify systems that anticipate, account for, and allow for these changes by moving from one Pareto design to another through module addition. Recognizing the potential for changes in needs to exceed the limits of a single Pareto frontier, the present paper introduces important advancements that extend development to modules connecting multiple disparate system concepts. As such, the search for suitable system designs is extended from a Pareto frontier that characterizes one system concept to a Pareto frontier that characterizes a set of system concepts. An expanded methodology is described, and a tri-objective hurricane and flood resistant residential structure example is used to demonstrate the method. The authors conclude that the developed method provides a new methodology for selecting platform and module designs in the presence of multiple system concepts, and is capable of identifying a set of modular system designs that are well-suited to satisfy changing needs over time.
