Rain Water Energy Harvest We are a design team in a green technology company and we have been commissioned to do a design with the following mission statement: Design a device to convert the potential energy of rain fallowing on residential houses into energy and store it in batteries. The main buyers of this device are regular home-owners and builders. The product is to be DIY and available at home-improvement retail stores. The device is to have a payback period of 5 years in an area with an average rainfall similar to Portland, Oregon. The Steps of the Design Process Develop PDS PDS document (dynamic document) – – External search - Existing products and related technologies (Research) – Internal search (Brainstorming) Lots of – – Evaluation and selection Select one idea to pursue – – Detail design (engineering) physical details – – Prototyping, testing, evaluating feasibility evaluation, improvement suggestions – – Documentation production drawings, design process, user manual, safety guidelines – – Identification of Customers External customers Customer What do they want Home owners Cost, Payback period, Reliability, high energy harvest, Ease of installation, (end users /buyers) safety, esthetics, ease of operation, low maintenance, long life, Anti Theft Builders (buyers) Cost, ease of installation, performance, safety, Retailers Cost, Nice packaging Long shelf life, exciting features. Small package sizes, Long warrantees, Reliability Government Codes, regulations, laws, city, state, Fed, local Fed/State/city/local Shipping Size, weight, mode of transportation Codes and Standard sizes, tests, standards Manufacturing Manufacturable, manufacturing site limitations Service and maintenance Low maintenance, low cost, ease of maintenance, standard replacement parts, available tools Internal customers
