“…The literature describes numerical approaches to dealing with uncertainties by minimizing risks while maximizing the versatility of products in an iterative optimization process [30], an approach that acknowledges the high level of uncertainty that exists in the developing market context. Others have attempted to deal with market uncertainties in low-income settings by taking a "hybrid design" approach in which incremental product improvements are offered following a small initial investment by the customer [5].…”

Product Design Supporting Improved Water, Sanitation, and Energy Services Delivery in Low-Income Settings

Several approaches have been proposed in the literature supporting product design applied in low-income settings. These approaches have typically focused on individual- and household-level beneficiaries, with an emphasis on participatory, human-centered co-design methods. In this paper, we present a design approach that is, in contrast, focused on supporting providers of improved water, sanitation, and energy services. We establish requirements for design in these contexts, especially addressing design iteration. We describe sets of feedback systems between designers and various sources of expert knowledge, codifying roles of design stakeholders in this context. We demonstrate these principles across three case studies: a sanitation service monitoring technology in Kenya; a water flowmeter technology in Kenya; and a water storage monitoring technology in Sierra Leone.

The article provides general data on the scale and prospects for the use of block-modular principles for constructing technical objects in various industries, in particular, in agriculture in the development of tillage and sowing units. In forestry, the block-modular construction of tillage tools has not found a wide-spread use, therefore, designs adapted to perform a single technological operation within a specific tech-nology prevail. At the same time, all this variety of specialized machines remains unclaimed, since Forest enterprises at the present stage of development are not capable of purchasing and operating a wide range of equipment and are limited to a very narrow set of obsolete tillage tools. To solve these problems, the author applied block-modular principles for constructing technical objects for developing a set of tillage forest tools. A constructive description of the proposed basic modular platforms (single-bar rear-mounted, double-sided rear-hung and front-hung) and various interchangeable modules of the working bodies is given. The possible options for the layout of modular tools in 3D CAD software SolidWorks have been worked out and an example of machine tractor unit based on a multifunctional modular plow has been presented. The analysis of the structures confirmed that the tools equipped with various working modules are capable of effectively performing all operations on basic soil preparation, carrying out agrotechnical treatments, as well as partly sowing and planting of forest crops in various conditions. Thus, a large variety of used forest tillage equipment used can be reduced to a narrow range of highly adaptable modular tools.

“…The mathematical modeling approach involves designing for a set of constraints and objective functions using defined variables. In this method, a design structure matrix is commonly used to represent relationships between components and objectives [78][79][80]. These methods are useful during product development and product planning while considering many factors.…”

This work explores an additive-manufacturing-enabled combination-of-function approach for design of modular products. AM technologies allow the design and manufacturing of nearly free-form geometry, which can be used to create more complex, multi-function or multi-feature parts. The approach presented here replaces sub-assemblies within a modular product or system with more complex consolidated parts that are designed and manufactured using AM technologies. This approach can increase the reliability of systems and products by reducing the number of interfaces, as well as allowing the optimization of the more complex parts during the design. The smaller part count and the ability of users to replace or upgrade the system or product parts on-demand should reduce user risk, life-cycle costs, and prevent obsolescence for the user of many systems. This study presents a detailed review on the current state-of-the-art in modular product design in order to demonstrate the place, need and usefulness of this AM-enabled method for systems and products that could benefit from it. A detailed case study is developed and presented to illustrate the concepts.
