1. Engineering Design A 10-Step Process

2. 10 Stages to Design Identify the problem Define the working criteria/goals Research and gather data Generate creative ideas Analyze potential solutions Develop and test models Make the decision Communicate and specify Implement and commercialize Review and assessment

3. Identify the Problem Reduce to basic needs Beware of solutions in the problem statement King of the Mountain – “Build a machine that can place a ping-pong ball higher, between the marks, than an opposing machine”

4. Working Criteria/Goals Constraints – limits on design options Physical size Available materials Available technology Goals – targets for design success Size or weight Ease of use Manufacturing ease Safety Environmental concerns – recycle?

5. Research/Gather Data Library Journals Textbooks Internet Looking for: Existing technology New materials/applications Similar Products Related ideas

6. Generate Ideas Brainstorm No analysis/discussion More ideas = better Break into parts Motion up the hill Steering Raise the ball Defensive action

7. Analyze Potential Solutions Narrow the list Eliminate duplicates Ask clarifying questions Eliminate least likely candidates Meet the constraints? Common sense concerns? Require new technology? Vote for top three

8. Analyze Potential Solutions Consider remaining ideas Economic analysis Basic engineering principles Compatibility with criteria/goals Manufacturing Marketing Human factors

9. Develop and Test Models Models Mathematical Computer Graphs/diagrams Physical Testing Durability/reliability/strength Prototyping Manufacturing/quality

10. Decide! What’s best? Decision criteria Decision table Weighted table Intangibles Reduce to cost Ranking Decision makers

11. Communicate! Design process/Decision analysis Plans Specifications Who needs to approve before the project succeeds? Manufacturing Sales Legal

12. Implement/Commercialize New team needed to bring to market Management Technical HR/Personnel Purchasing Marketing Sales Legal Design Team may play smaller role here

13. Review and Assess Project in Full Production Project Team released to other work Product performance review Process review What worked well Could changes in process improve: Product quality Time to market
