1. Product Design and Development Chapter 12, 13 & 14 – Prototype, Robust Design & Patent and Intellectual Property

2. Ch 12: Prototypes Prototype: an approximation of the product along one or more dimensions of interest Types: Physical – a physical example to test Analytical – a computer generated example Comprehensive – a physical example shared with customers to analysis

3. Prototype Uses Learning – Will it work?, Does it meet the customers need? Communication – shared with vendors, customers, team members, equipment suppliers to communicate expectations Integration – ensure that components and subsystems work together as expected Milestones – demonstrate the teams progress

4. Principles of Prototypes Analytical prototypes are more flexible than the physical. Physical prototypes are required to determine unanticipated issues May reduce the cost of iterations May expedite other development steps May restructure task dependencies

5. Technologies 3D CAD Modeling Freeform fabrication 3D printing or rapid prototyping

6. Ch 13: Robust Design Robust Design – a product or process that performs as intended even under non-ideal conditions, such as manufacturing process variations or a range of operating situations Noise factor – uncontrolled variations that may affect performance

7. Design of Experiments (DOE) 1. Identify control factors, noise factors, and performance metrics 2. Formulate an objective function 3. Develop the experimental plan 4. Run the experiment 5. Conduct the analysis 6. Select and confirm factor set points 7. Reflect and repeat

8. Ch 14: Intellectual Property What is it? Patent  Design  Utility Trademark Trade Secret Copyright
