GE 1011: Introduction to Engineering Engineering Design Process Dr. Fahid Aslam Department of Civil Engineering, College of Engineering Prince Sattam bin Abdulaziz University, Saudi Arabia  STEM STEM is an approach to learning and development that integrates the areas of science, technology, engineering and mathematics. 1. Critical Thinking (you will find problems) 2. Logical Thinking (You will solutions) 3. Innovative thinking (Climax of engineering knowledge)  Why STEM is Important  The global economy is changing. Current jobs are disappearing due to automation and new jobs are emerging every day as a result of technological advances.  The continual advances in technology are changing the way students learn, connect and interact every day. Skills developed by students through STEM provide them with the foundation to succeed at school and beyond.  Employer demand for STEM qualifications and skills is high, and will continue to increase in the future. Currently, 75 per cent of jobs in the fastest growing industries require workers with STEM skills.  STEM empowers individuals with the skills to succeed and adapt to Why STEM is Important  Engineering Design Process The engineering design process is a series of steps that engineers follow to find a solution to a problem.  Engineering Design Process 1. Define The Problem What is the problem that needs to be solved? Who is the design product for, and why is it important to find a solution? What are the limitations and requirements? Engineers need to ask these types of critical questions regardless of what is being created. 2. Brainstorm Possible Solutions Good designers brainstorm possible solutions before opting to start a design, building a list of as many solutions as possible. It is best to avoid judging the designs and instead just let the ideas flow. 3. Research Ideas / Explore Possibilities for your Engineering Design Project Use the experience of others to explore possibilities. By researching past projects you can avoid the problems faced by others. You should speak to people from various backgrounds, including users or customers. You may find some solutions that you had  Engineering Design Process 4. Establish Criteria and Constraints Having listed potential solutions and determined the needs of the project alongside your research, the next step is to establish any factors that may constrain your work. This can be done by revisiting the requirements and bringing together your findings and ideas from previous steps. 5. Consider Alternative Solutions You may wish to consider further solutions to compare the potential outcomes and find the best approach. This will involve repeating some of the earlier steps for each viable idea. 6. Select An Approach Once you have assessed your various options you can determine which approach best meets your requirements. Reject those that don’t meet your requirements.  Engineering Design Process 7. Develop A Design Proposal Having chosen your approach, the next step is to refine and improve the solution to create a design proposal. This stage can be ongoing through the length of your project and even after a product has been delivered to customers. 8. Make A Model Or Prototype Use your design proposal to make a prototype that will allow you to test how the final product will perform. Prototypes are often made from different materials than the final version and are generally finished to a lesser standard. 9. Test And Evaluate Each prototype will need testing, re-evaluation and improvement. Testing and evaluation allows you to see where any improvements are needed.  Engineering Design Process 9. Test And Evaluate Each prototype will need testing, re-evaluation and improvement. Testing and evaluation allows you to see where any improvements are needed. 10. Refine The Design Once testing has been completed, the design can be revised and improved. This step can be repeated several times as more prototypes are created and evaluated. 11. Create The Solution After your refinements have been completed and fully tested, you can decide upon and create your finished solution. This may take the form of a polished prototype to demonstrate to customers. 12. Communicate The Results The final stage is to communicate your results. This can be in the form of a report, presentation, display board, or a combination of methods. Thorough documentation allows your finished  Ergonomics and Engineering design Process  The application of psychology and physiological principles to the engineering and design of products, processes, and systems.  Four primary goals of human factors learning are:  To reduce human error,  Increase productivity,  Enhance safety,  System availability and comfort with a specific focus on the interaction between the human and the engineered system. Questions ?
