Project 2 Laura Gibbons Neil Kruse Paul Omelko Denise Babilya April 11, 2012
Sequence of Activities • Interview users to establish requirements • Search the literature and Patents • Find competitive products and research their reviews • Create a hierarchical list of customer needs 1.5 Revise Problem Statement • Functionally decompose the project • Research the literature on similar subtask solutions • Generate concepts • Yet to do: • Select promising concept(s) • Perform detailed analyses of concepts • Perform simulations • Material selection/availability • Component selection/availability • CAD Drawings • Assemble Prototype • Develop testing protocol • Perform tests • Preparation of final presentation (Poster)
Introduction • Place of concern: New York City • About 2,764,058 people in New York are living in Poverty and many of them make money by selling merchandise on the streets
Project Management • We created our copy of project management charts in excel and were able to keep up to date with the dates we had decided on as benchmarks for each part of the project. We met outside of class to organize our report, and generate ideas for the bike shelf.
External Information • Surveys: • Surveymonkey.com • We received 41 responses • The survey was based on a hypothetical situation where the person is a street vendor and we are asking them, if they were in the situation, what factors would that consider when buying a shelf bike. We also asked what they thought of the idea, and we got a lot of positive feedback. • We also sent out a second survey to people who live in the New York area, asking them what they typically see on the streets of New York. What products vendors are selling and how they sell them. Many said it is common to find scarves, hats, and other such accessories during the winter. They also said that you can find NYC memorabilia being sold.
After Analyzing our survey results, we concluded that the vendors would most like us to focus on weather resistance and durability. They also considered the weight of the shelf very important.
Revised Problem Statement • Our initial problem was to design a shelf that attaches to a bike and helps street vendors transport their products to major selling areas. The shelf is to also serve a display for the products. From our customer needs assessment, we determined what features we want our bike shelf to have. Our most prominent desired features were durability and weather resistance. The next major factors were the weight, size, and capacity. The last few were the materials, cost and eco-friendliness. From these, we determined that we want a long-lasting, durable product that will transport a sufficient amount of goods, and be relatively low in cost.
Top Concepts • For concept generation we decided to focus on the shelf being attachable, collapsible, the size it would be, and the materials
Morphological Chart Collapsible Attachable Materials Size Fold by one side Nylon Lock with Spike Attachable cart Collapses out Open top box Plastic Hook Permanently attached Aluminum 6106 Shelf-to-box Long and flat box Holes in box Netted open top box Iron
Conclusion • Our next step is to create a Pugh chart based off of the concepts we have generated. From there we will decided on our final design, we will also make a decision on what materials we will use and attempt to create a model of this bike shelf.
