Graham Chair Endowment Antilium Project University of Michigan THE VILLAGE WELL Kyle Marsh, Vineet Maheshwary, Amy Kopin ANALYTICAL PRODUCT DESIGN ME 499/ME599/ARTDES300 Design Concept Project Goal: Marketing Analysis Specifications: To develop a low cost, simple wind powered water pumping system for use in developing countries. This system is intended to expand access to clean water as a for-profit enterprise. We conducted a survey that included citizens of Ghana. Although we had initially hypothesized that price was very important, and that customers would prefer to spend time if it meant spending less money; our survey results did not agree with our hypothesis. Our respondents reported that they would prefer a greater initial cost if that meant it came ready to install. They desire a system that: Market Need: • It is estimated that Ghanaian children spend one quarter of their waking hours fetching water for their families. • Market segment • 500 rope pumps on community wells (Drilled or hand dug wells) with a mean of 80 users. • 2,500 rope pumps on family wells with a mean of 20 users. • Totaling 90.000 new users a year or an additional 4.5 % of the rural population a year. • Provides water for 100 people. • Requires hand operation no more than 4 days a month (due to insufficient wind speeds). • Requires regular maintenance once a week • Has a system cost of $800.00. Windmill rotor will turn this gear via a pulley system. Hand crank mechanism for periods of insufficient wind. Conjoint Analysis Survey Data CAD Model of Rotor and Drive Pulley Simple operation, water is lifted by disks. Economic Analysis Engineering Analysis Objective: Maximize water output over the entire day • Low initial investment cost: $2000 due to simplicity of equipment: can be built with hand tools • Fixed costs create break-even point at 3 years when maximum production is reached Engineering design optimization model seeks to optimize the total hydraulic output over the entire day. This can be done by utilizing the wind energy efficiently at the widest feasible range of wind velocities. The key variable to achieve this is the torque on the shaft attached to the rotor.
