Introduction to the Major Design Project (MDP) University of Western Ontario Faculty of Engineering Science Introduction to Engineering Design, ES 1050 November 5, 2009

Problem Statement Design an interactive display to demonstrate one green technology.

Problem Statement The problem is NOT to design or implement a green technology. It is to demonstrate an existing technology

Problem Statement Some areas to consider:  Who is the audience (kids, students, professionals, general public?)  Where is the display (museum, science centre, mall?)  Which technology (energy, recycling, pollution?)

Steps in MDP  Problem definition  Background research (SOTA)  Specifications  Detailed Design  Prototyping

Problem definition Things to consider:  What area will we focus on?  Who is the user?  What does the user need? (What are we trying to teach?)  Do not define the problem to limit the solution.  Consider a multi-disciplinary approach.

Constraints Things to consider:  Size (50cm x 50cm x 50cm)  Weight (10kg)  AC Power (max 100W, CSA approval required)  Safety (no hazardous chemicals or hazardous motions)  Should survive its expected working life

Budget Constraints The budget is limited to:  No more than $100 per team member cash contribution ($400 per team)  One hour UMS time  Maximum $200 borrowed/scavenged/donated parts  Computers do not count towards budget

Project organization The MDP is organized as follows:  Work in studio teams  Work during studios and in team meeting times throughout semester  Design reviews (for credit) in studio  Deliverables and progress reports

Phase I Report One report per team:  Similar to CV submissions  Problem definition  Identification of objectives and constraints  Concept generation (creativity and innovation)  Concept selection (using structured techniques)

Background research (SOTA) State of the Art (SOTA) investigates:  Other solutions to similar problems  Emerging technologies that may help Make sure your SOTA contains analysis, not just data. Individual submission

Design reviews Graded by team:  Occur three times throughout project  Two informal discussions  One formal presentation  Allow instructors to monitor milestones

Final Report One report per team:  Should report on the whole project  Includes design specifications and drawings  Includes modeling and experimental data  Should include a user’s manual

MDP Showcase The MDP prototypes are displayed to the University community and the public at the showcase. Here are some photos from previous years:

MDP Showcase The angular momentum swing

MDP Showcase The solar powered roller coaster

MDP Showcase The turbine display

Evaluation You will be evaluated based on:  Three design reviews  SOTA  Design notebook  Prototype/Showcase  Design reports  Operating manual
