Engineering 220 – Dynamics

Group Design Project

Spring 2006

Design project rationale:

Crowd entertainment at sporting events during breaks in the action is always needed. One common activity at a basketball game is to have fans attempt to shoot a basket in order to have a chance at winning a prize. Your team is to design a mechanically operated device that can shoot a basket using tennis ball launched between the free-throw line and court boundary line at the opposite end of the court. The shot must go over the scoreboard and enter the hoop after banking off the backboard.

Design Project Goals:

Design a device that meets or exceeds the following criteria:

· Adjustable launch angle and/or speed for ball

· Allowed adjustments cannot result in possible injury to the crowd

· Easy to operate

· Safe to operate given simple instructions

· have minimum weight and volume for easy storage

· be inexpensive (your prototype should not exceed $50 for parts and outside labor)

Design Methodology:

Follow the process outlined in Introduction to Engineering Design, by Eide, Jenison, Mashaw, and Northup, published by McGraw-Hill’s BEST series, pages 71-75.

Design team structure:

Effective teams must work together. Although all members do not have to get along personally to create a successful team, each member of the team must have a common goal and be willing to execute their fair portion of the work. Some structure is usually necessary in order to form a successful team. As such, your design team will consist of the roles used in class for team problem solving and defined by the handout “Performance Criteria for Team Roles”, with the Spokesperson role replaced by Technology Specialist. You may use other roles from the handout if you feel they are appropriate/helpful.

Captain Technology Specialist

Recorder Planner

Reflector Timekeeper

Each team member should spend a portion of the semester in each role. This is easily accomplished by dividing time in the various roles according to the due dates in the timeline below.

Timeline:

As stated in the syllabus, there will two design progress reports. The final design report and oral presentation will be prepared for presentation at the end of the course. The following dates will be your design project deadlines:

February 22 – First progress report due

April 12 Second progress report due

May 10 – Final design paper and oral presentation due

Grading:

For each progress report, the final design report, and the oral report, each team member is to e-mail the instructor with peer grades assigned to each group member (including yourself) with a short explanation of the assigned grade. These peer grades will be used to adjust individual grades for the project at the discretion of instructor. For the overall design grade, see the design rubric included in the syllabus.

2 design progress reports

Purpose:

1) to ensure that your group is making sufficient progress

2) to demonstrate that you have been able to apply some of the principles of engineering statics

3) to give your group practice in documenting your design work

Your progress reports should include:

1) the current status of the design project including how your team is moving through the design cycle

2) a summary of the engineering analyses (calculations) you have performed that follows the problem solving methodology used in class

3) the Recorder’s log of meeting activities

4) An SII from each team member regarding your personal performance and your peer’s performance during the time period for the report.

These progress reports are to be submitted to the instructor using MS Word.

Final design report

This report is a formal report on the final form of your design. It should include the following parts:

1) Cover page

2) Executive summary (one page)

3) Detailed Design Description

5) Supporting Calculations

6) Complete Recorder’s log

7) Final SII from each member for personal and peer overall performance

The final design report is NOT the place to describe how you came to your final design, it is a report only on the specifics of the final design itself.

The final report is to be submitted to the instructor using MS Word.

Oral presentation on final design

Your group will be responsible for giving an oral presentation showing off the features of your design. It should include a demonstration of the use of your product. This presentation should be made as if you were in a business meeting to convince your company to fund any further design work for this device with the intent of producing it to sell on the market. You will have 10 minutes for this presentation.
