Assignment #2: Team Project Proposal

ME302 Assignment #2: Team Project Proposal (Due in class on Monday, October 8, 2007)

1. You will work in teams as established in class. Plan a meeting and select one member to serve as team leader. The team leader will be the primary point of communication with the instructor and TA’s, and will be responsible for coordinating the overall efforts of the team.

2. Discuss, select, and purchase a small system to reverse engineer. It may be, for example, a mechanical toy, a hand tool, or a small home appliance. It should have overall dimensions such that you can hold it easily in one hand. The system should preferably be mechanically- driven (e.g., spring-wound or friction-flywheel driven rather than battery-operated).

3. Your device must have at least 2 subsystems, and each subsystem must have at least 2 components. You should be able to disassemble and reassemble it with readily available tools. Be cautious about choosing something that is difficult (or impossible) to take apart, like a plastic toy with glued joints or an appliance with a welded casing. Try to select an inexpensive device, and you might want to buy an extra one in case you have to "sacrifice" the device in the process of disassembling it for the first time. Pool your money together as a team, and again try not to select something too expensive.*

4. Prepare and submit the team proposal. It should include the following main components: a. Cover page, listing the title of the project (e.g., "Reverse Engineering of a Hand-Operated Mechanical Kitchen Mixer"), your team name (e.g. “Alpha Engineering Group”), the names of the team members, including designation of the team leader, everyone's email address, your graphics section unique number, and your graphics lab instructor’s name. b. General Description (about 1-2 pages) of the system selected for reverse engineering. The description should include: 1. a customer’s perspective, 2. an engineer’s perspective, 3. a listing of functional requirements of the device, and 4. a listing of anticipated subsystems. c. Graphical Picture (additional 1 page) of the system selected for reverse engineering. The graphic can be a sketch of the system-wide device, a photo (analog or digital) of the device, or an original/Xerox copy from the package cover illustrating what the device looks like. ______

*Note: When selecting your device, keep in mind also that you will later be sketching components, building 3-D computer models of them, redesigning components if needed, and making rapid physical prototypes of the parts. So, avoid objects that have complex or sculpted surfaces that encase the mechanical components inside. Also do not select a device that is too small (cigarette lighter) or too thin (ball point pen). These will not work. Grading Policy Sheet for Assignment #2 Reverse Engineering Project Proposal
