1. Bike-to-Shelf System for Nigerian Marketplace Team 5 Daratu Derga, Matt Murphy, Frankie Reluzco, Kristen Van Tilburg Abstract Our objective for “Project 2: Design for Emerging Markets” was to develop a shelf system that can be strapped onto a bicycle, carry goods very securely and open up to provide table space to display the items for potential buyers. We explored this type of product by using concepts generated from every member in our group, deciding which designs would be most beneficial and researching patents regarding any type structures that would impede us in our progression. After this very extensive research, we found a product that we think will revolutionize the mobile sales of goods in the street.

Metal hinges can be less expensive if copied and mass produced. This would allow their implementation into our design 3. Instead of a high quality tarp to protect goods, a lower quality, thin plastic material could be used to decrease cost. 4. The table and legs could be made out of different materials to decrease weight while retaining support. The design allows them to be separated and later assembled.

Our team came up with an efficient bike-to-shelf system that can carry goods securely strapped to a bike then opens up to provide table space displaying the items to potential buyers. The folded table is strapped on top of a shelf that is clamped to the bike. The table legs and a tarp for weather protection are stored within the folded table. When the table is detached, unfolded, and assembled the four legs slide easily into each of the holes drilled into the corners of the table. The design minimizes the skill and effort of assembly and the folded table will be taller than it is wide making it more portable both of these important factors appeal to the customer needs ease of assembly and portability. Our product consists of fairly simple and low cost materials. The major materials used are six stainless steel hinges, three sheets of polyethylene, a small tarp, and four pieces of white oak for the legs. Most of which are recyclable and are not harmful to the environment. In addition it will not cause any pollution since it only requires manpower so our product is as eco-friendly as it can possibly be.
