+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.

FUNCTION ART

  Bike ShelfPosition of

rackUS 5341971This design has a rack in the back which is attachable or detachable. We want our product to be in the rear and this patent helps determine how we could do that.

Attachment to bike

US 5341971US 2011/0123949 This attaches the rack to the axles and the bar beneath the seat. It will help us determining quality points of attachment for our design.

Folding of rack

US 529486This has a collapsible rack. The product is for carrying luggage on a bike, but when the rack is not in use, it folds in half to make it more compact for putting in storage.

Bike US D512664 S This is a patent for a bike. It shows the build of the forks and the frame. Without this bike, our patent would not be able to exist.

+Top Concepts

For concept generation we decided to focus on the shelf being attachable, collapsible, the size it would be, and the materials

+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.
