  1. EngineeringDesign Introduction to Mechanical Engineering The University of Texas-Pan American College of Science and Engineering

  2. Objectives • Define Engineering Design. • Define and explain the Engineering Design Process. • Assignment: Prepare a Gantt Chart for your Final Design Project (Project Timeline). [ See Example Report posted in my website ]

  3. What is Engineering Design? • To create, fashion, execute, or construct according to plan. • It defines a natural process as “a natural phenomenon marked by gradual changes that lead toward a particular result: a series of actions or operations conducing to an end…

  4. What is Engineering Design? • The ABET Definition: It is the process of devising a system, component, or process to meet desired needs. It is a decision-making process in which the basic sciences and mathematics and engineering sciences are applied to convert resources optimally to meet a stated objective.

  5. What is Engineering Design? • The ABET Definition (cont): Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation. It is essential to include a variety of realistic constraints, such as economic factors, safety, reliability, aesthetics, ethics, and social impact.

  6. Ten-Stage Design • Identify the problem/product innovation. • Define the working criteria/goals. • Research and gather data. • Brainstorm/generate creative ideas. • Analyze potential solutions. • Develop and test models. • Make the decision. • Communicate and specify. • Implement and commercialize. • Perform post-implementation review.

  7. Stage 1: Identify the Problem • Establish the actual problem clearly, and identify sources of information to help understand the scope and nature of the problem. • Statement of the problem.

  8. Stage 2: Define the Working Criteria and Goals • How much will it cost? • Will it be difficult to produce? • What will be the size, weight, and strength? • What will it look like? • Will it be easy to use? • Are there any legal concerns? • Will it be reliable and durable? • Can it be recycled? • Is this what the costumer really wants? • Will our customers want to purchase it?

  9. Stage 3: Research and Gather Data • What information has been published about the problem? • Is there a solution to the problem that may already be available? • What is the ratio of time spent compared to overall costs?

  10. Stage 3: Research and Gather Data • Libraries. • Professional associations. • Trade journals and publications. • Newspapers and magazines. • Market assessment surveys. • Government publications. • Patent searches. • Competitor’s product.

  11. Stage 4: Brainstorm/Generate Creative Ideas • Try to include engineers, scientists, technicians, shop workers, production staff, finance personnel, managers, computer specialists, and a few clients.

  12. Stage 5: Analyze Potential Solutions • Common sense. • Economic analysis. • Analysis using basic engineering principles. • Estimation. • Analysis of compatibility. • Computer analysis techniques.

  13. Stage 6: Develop and Test Models • Mathematical models. • Computer models. • Scale models. • Diagrams or graphs.

  14. Stage 6: Develop and Test Models • Durability. • Ease of assembly. • Reliability. • Strength. • Environmental. • Quality consistency. • Safety. • Consistency of testing.

  15. Stage 7: Make the Decision • Establish a means to compare and evaluate results from the testing stage to determine which, if any, of the possible solutions will be implemented.

  16. Stage 8: Communicate and Specify • Before a part, product, or structure can be manufactured, there must be complete and thorough communication, reporting, and specification for all aspects of the item.

  17. Stage 9: Implement and Commercialize • Management and key supervisory personnel. • Technical representatives • Human resources, financial, purchasing, marketing, and sales personnel. • Attorney and legal support staff.

  18. Stage 10: Perform Post-Implementation Review and Assessment • Review data on production efficiency, quality control reports, sales, revenues, costs, expenditures, and profits. • Detail product’s strengths and weaknesses. • Suggest improvements.

  19. Open Forum
