  1. Objectives: Indicator Statement: Develop abilities to apply and analyze the design process. (ITEA, STL 11) Objective(s): Identify the design problem to solve and to decide whether to address it. (ITEA, STL 11-M) Identify criteria and constraints and determine how these will affect the design process. (ITEA, STL 11-N) Refine a design by using prototypes and modeling to ensure quality, efficiency, and productivity of the final product. (ITEA, STL 11-O) Evaluate the design solution using conceptual, physical, and mathematical models at various intervals of the design process in order to check for proper design and to note areas where improvements are needed. (ITEA, STL 11-P) Develop and produce a product or system using a design process. (ITEA, STL 11-Q) Evaluate final solutions and communicate observations, processes, and results of the entire design process, using verbal, graphic, quantitative, virtual, and written means, in addition to three-dimensional models. (ITEA, STL 11-R) Define the problem. Brainstorm. Research and generate ideas. Identify criteria and specify constraints. Explore possibilities. Select an approach. Develop a design proposal. Make a model or prototype. Test and evaluate the design. Redesign. Create or make it. Communicate processes or results

  2. The Big Picture….. • Engineering is the discipline, skill, and profession of applying scientific, mathematic, economic, social, and practical knowledge, in order meet the needs and desires of people

  3. What do you think? What steps do you think were followed to create such an amazing innovation. What impacts might this technological development have? The Dragon is a free-flying, reusable spacecraft developed by SpaceX under NASA's Commercial Orbital Transportation Services (COTS) program. The Dragon spacecraft is made up of a pressurized capsule and unpressurized trunk used for Earth to LEO transport of pressurized cargo, unpressurized cargo, and/or crew members. Engagement

  4. Time to find out… • You will be given a set of index cards with different steps of a problem solving process. • With a partner, organize the steps in the order that you feel an Engineer would go through to solve a problem. • Be prepared to defend your sequence of steps Exploration

  5. Time to find out… • How did you do? • What order did you put the steps? • When called – come to the front board and put the steps in the order that you think an Engineer would go through to solve a problem. • Defend your order. Exploration

  6. Time to find out… • Define the problem. • Brainstorm. • Research and generate ideas. • Identify criteria and specify constraints. • Explore possibilities. • Select an approach. • Develop a design proposal. • Make a model or prototype. • Test and evaluate the design. • Redesign. • Create or make it. • Communicate processes or results Exploration

  7. Did you know… • How do you know if a problem really needs a solution? • The following are real solutions…. Pass the Butter Explanation

  8. Did you know… A long ride home after a long day at work. Explanation

  9. Did you know… Hot,hot, hot…. Allergies – pass the tissue.. Explanation

  10. Did you know… Sauce Dispensing Chopsticks! Self-Locking Bendy Bike Explanation

  11. Did you know… Gum Packaging...With Built-In Garbage Car Swivel Chair Explanation

  12. Did you know… It's A Fast Trip Back Down Children's Department? Just Up The Escalator, Through The Roof Explanation

  13. Did you know… Wasn't going to use the driveway anyway. A View...Without A Room Explanation

  14. Did you know… • Design problems are not always presented in a clearly defined form. • There are many formal and informal problem-solving strategies. • There are established design principles that are used to evaluate existing designs, to collect data, and to guide the design process. • The Engineering-Design process is a step-by-step problem-solving strategy • It includes criteria and constraints • It can be used to create solutions to problems to satisfy human needs and wants. Explanation

  15. Did you know… Form a Question • The Scientific Method is very important. • Gives us answers to the way the Universe works • It is linear in nature. • It has a starting point and ending point. • Once you report your results, you can then form a new question. Research the Topic Create a Hypothesis Create a Conduct Experiments Analyze your Data Draw Conclusions Report your Results Explanation

  16. Did you know… The Design Process is a circular process- it encourages changes and improvements. Explanation

  17. Did you know… Our Problem Solving Process Explanation

  18. Did you know… • Define the problem. • What is the problem that you are trying to solve? • Not all problems will be clearly defined. Problem Statement: The products that we buy in the store are packaged in many unique ways to insure that they arrive at the specified location without being damaged.    Design Brief: Design and construct a package that will protect a raw egg from being damaged when dropped from a height. What problem are we solving? Explanation

  19. Did you know… 2. Brainstorming. • Create a list of ideas • Sketch simple concept pictures • Work towards quanity • Never criticize anyone’s idea • Use “Mind Mapping” • Lets give this a try. • List possible ideas • Mind Map • Make at least three different sketches Explanation

  20. Did you know… 3. Research and generate ideas • What have others done? • What do you need to know? • science, math concepts • Look on-line • As you look at what others have done – do you have any more ideas? Cite your sources! Google is not a source! It is a search engine. Explanation

  21. Did you know… 4. Identify criteria and specify constraints • Now that you know the Problem and some information, it is time to look at what the requirements are. • This will include: • People, Time, Materials, Tools, Cost and other factors • This is an individual project. • You will have three days to build your design. • You may use any found material. • The container must be 8” x 8” x 8”. • Hold a Large Egg (teacher supplied day of testing). • Must be able to touch the egg from each side. • The lightest design that keeps the egg from cracking will earn 100 points • If the egg cracks, you will earn 70 points max. • Drop from 3rd floor to Commons. Explanation

  22. Did you know… 5. Explore possibilities. • Review the Problem – • Review the ideas you came up with – • Review your research (that is why you did it) • Review the criteria – • Come up with at least 3 different ideas • These are sketches with annotations! Now it is your turn. Explanation

  23. Did you know… 6. Select an approach- • Use a Decision Matrix. • This is a Table • Criteria along the top • Possible solutions along the left side • Use your ideas to complete this table. Explanation

  24. Did you know… • Analyze each idea based on the criteria • 4 = meets it perfectly • 3 = is close but not perfect • 2 = just a little bit • 1 = it is a stretch to say it comes close • 0 = does not meet the criteria • YES = 1 • NO = 0 • Total up the results. Explanation

  25. Did you know… • Analyze each idea based on the criteria • 4 = meets it perfectly • 3 = is close but not perfect • 2 = just a little bit • 1 = it is a stretch to say it comes close • 0 = does not meet the criteria • YES = 1 • NO = 0 • Total up the results. This is a sample of how it should work In the event of a tie – give weight to the “more important” criteria Explanation

  26. Did you know… • Create an argument on why your design is the best solution to the problem or why it is not. • This argument must be based on logic, facts, and data. • A valid argument also provides the facts and data for the opposing argument. • Your argument must be well written and make use of the references from your research Explanation

  27. Did you know… 7. Develop a design proposal • You will need to create a Multi-view drawing of your best solution. • Make sure that you include dimensions and other important information. • Some solutions may be complex and need many drawings to build from. • What you design here is what you will build and ultimately test. Explanation

  28. Did you know… 8. Make a model or prototype. • Once you have made your initial solution, take a picture of it. Explanation

  29. Did you know… 9. Test and evaluate the design. • You will need to create a test for your solution. • Some projects may be destroyed after testing, so you might want to come up with non-destructive tests. • Create a table to record your test results. 10. Redesign. • As you test your solution, you will make changes based on the results of the test. • Take pictures of these changes. Explanation

  30. Did you know… 11. Create or make it. • This is your final solution to the design. • Take a picture of the final solution. • Video you testing the final solution 12. Communicate processes or results • Explain what you did during this project • Imagine that you have 2 minutes to tell the class what you did and how you solved the problem. • Or explain why your solution did not solve the problem. Explanation

  31. Lets give it a try… Problem Statement: The products that we buy in the store are packaged in many unique ways to insure that they arrive at the specified location without being damaged.    Design Brief: Design and construct a package that will protect a raw egg from being damaged when dropped from a height. Elaboration

  32. Lets give it a try… • This is an individual project. • You will have three days to build your design. • You may use any found material. • The container must be 8” x 8” x 8”. • Hold a Large Egg (teacher supplied day of testing). • Must be able to touch the egg from each side. • The lightest design that keeps the egg from cracking will earn 100 points. • If the egg cracks, you will earn 70 points max. • Drop from 3rd floor to Commons. • Part of this grade will be based on competition. • 100 pts for the lightest solution that keeps the Egg from cracking • 98 pts for the second, 96 for the third… and so on. • In the event of a tie – the mean score will be given • 70 pts will be awarded for solutions that meet all of the criteria, but let the Egg crack or break. Elaboration

  33. How well did you do? Evaluation
