Transcript Warm Up
Warm Up On the notecards on your table, complete the following; 1. List the different forms of Transportation Technology. 2. List the four key components of flight. 3. Convert 10.28 cm to inches The Engineering Design Process From Problem to Solution Objectives Students will be able to; • Develop abilities to apply and analyze the design process. • Identify a problem, and develop a process in order to solve it. • Identify criteria and constraints and determine how these will affect the design process. • Identify and list the 12 steps of the design process. THE BIG PICTURE What is Engineering? Engineering is the discipline, skill, and profession of applying science, math, social, and practical knowledge in order to meet the desires and needs of people. Breakdown Your table will be given a set of items with different steps of the problem solving process. With your table, organize the steps in the order you feel an Engineer would go through to solve a problem. Be Prepared to defend your sequence of steps. You have 3 minutes to discuss and order your steps. Is That Right? How did you do? What order did you put the steps? Lets Find Out… 1. Define the Problem 2. Brainstorm 3. Research & Generate Ideas 7. Develop a 8. Make a 9. Test and Design Prototype Evaluate 4. Identify Criteria & Constraints 10. Redesign 5. Explore 6. Select and Possibilities Approach 11. Create or Make it 12. Communicate Results Discovery How do you know if a problem exists? EXPLORE IDEAS! Failure is an Option! If you design fails, don’t give up! Re-Design and keep on trying, giving up is never an option! Explore.. Our Problem Solving Process Design Process Breakdown 1. Define the Problem The Engineer must determine what the problem is that needs to be solved. Cable Car Example • You must build a cable supported car that will traverse 15 feet along the line as quickly as possible, while holding a passenger. Design Process Breakdown 2. Brainstorm Ideas Brainstorm Ideas! This step typically involves making a mind map, a list and possible thumbnail sketches. Cable Car Example • Create a small box and use the balloon to push it forward • Make a rubber-band powered car • Origami style box, straw attaches to cable… Design Process Breakdown 3. Research & Generate Ideas Research possible solutions and see if something similar has been created. Cable Car Example • Style like a current ski-lift • Use the dome shape design that can be attached to a cable… Design Process Breakdown 4. Identify Criteria & Constraints Find out any rules and restrictions the design has. What is required in it? What is the time restraint? Cable Car Example • Must only use the given resources • Must travel 15 feet • Passenger must not fall Design Process Breakdown 5. Explore Possibilities Rate different ideas using a decision matrix to determine which is the best solution. Cable Car Example Resources Option 1 Option 2 Option 3 Distance Weight Safe Total Design Process Breakdown 6. Select an Approach Using the decision matrix, the engineer selects the highest rated design. Cable Car Example Resources Distance Weight Safe Total Option 1 4 3 4 2 13 Option 2 3 3 5 4 15 Option 3 4 2 4 4 14 Design Process Breakdown 7. Develop a Design The engineer will sketch a multiview drawing of their chosen solution. Cable Car Example Design Process Breakdown 8. Develop a Prototype Using the sketches, create a scaled model or prototype of the design. Cable Car Example Design Process Breakdown 9. Test and Evaluate Test your prototype and analyze the outcome of the test. Cable Car Example Design Process Breakdown 10. Re-Design If needed, re-design the product in order to solve the solution more effectively. Cable Car Example Design Process Breakdown 11. Create or Make the Final Design Make the full scale version of the solution. Cable Car Example Design Process Breakdown 12. Communicate Results The engineer will communicate the results of their product to peers or clients. Cable Car Example Design Time You are to create a poster showing how the design process works. • Come up with a problem to solve (e.g. I need to create a device that will feed my dog.) • Explain and Illustrate each step of the design process. • Your poster should be neatly drawn and colored. Review If I am making a multiview drawing of a design, which step am I doing? Develop a Design Which step of the design process involves making a mind map or a list? Brainstorming Which two steps of the design process use a decision matrix? Exploring Possibilities & Selecting an Approach Review What are the twelve steps of the design process? 1.
