EE311- Engineering Design Manual James Carroll, Associate Professor Electrical and Computer Engineering
About Eng. Design Teams Consist of Members with a Mix of Backgrounds and Training: –Scientists: Have strong training in math and science which emphasizes the theoretical. Scientists ask "Why?" questions.
About Eng. Design Teams –Engineers: Attempt to do something useful with scientific theories and principles, called design, i.e., a creative process that produces in a new device, system, structure, or process that satisfies a specific need. –Technologists: Do much of the actual implementation of the engineering designs, like CAD drawings, testing, data taking and reduction, and directing craftspeople during fabrication. –Craftspeople: Are the practical or implementation end of the spectrum. They primarily manufacture or assemble the products designed by the rest of the team, e.g., welders, machinists, etc.
The Design Process
Detailed Design Process w/Iteration
The Problem Statement and Functional Requirements
Be Creative and Think Laterally!
Identifying and Evaluating Design Alternatives: An Example
Identifying Design Alternatives: Weighted Objective Trees
Developing Models and Prototypes All modeling can be broken down into one of two categories: –Descriptive Models: Depict ideas, products, and processes in a way that is recognizable. The goal is to show what a design would look like if it were created. Examples: Engineering drawings, 3D computer models, or scale models –Predictive Models: Used to test and understand how designs ideas, products, and processes will perform. May bear little or no resemblance to the overall design. Examples: Mathematical equations or graphs showing a relationship between design requirements
Developing Models and Prototypes Scale models are one of the most basic and generally useful because they are very much hands-on and provide a good feel for a design and its features Computer simulation and animation are two other common model types
Common Engineering Analyses
Thoughts on Project Management
Do Not Leave Team Development to Chance!
Keeping on Schedule
Four Stages of Team Development
