E10_JA_2/08 1 Engineering Design Video Video Summary of the Video Summary of the Video Inventor's Characteristics Inventor's Characteristics The Engineering Design Process. The Engineering Design Process.

E10_JA_2/08 2 IDEO’s Basic Design Steps (Ref. The Video from ABC News) STEP 1: Observation (study the problem) (study the problem) STEP 2: Brainstorming (generate as many ideas as possible) (generate as many ideas as possible) STEP 3: Sketching (Putting ideas on paper) (Putting ideas on paper) STEP 4: Prototyping (rabid, unfinished prototypes to get the idea into a users hand to test.) (rabid, unfinished prototypes to get the idea into a users hand to test.) STEP 5: Implementation (The most important step) (The most important step)

E10_JA_2/08 3 Characteristics of Inventors* 1. They are not troubled by the idea of failure. 2. They realize that : failure can be learned from failure can be learned from the ‘failed’ technology can later be re- used for other purposes the ‘failed’ technology can later be re- used for other purposes that one works in advanced areas where failure is a real possibility. that one works in advanced areas where failure is a real possibility. 3. Innovators are curious about what is happening in a myriad of disciplines, not just their own specialty. *2005/6 MIT survey (Wikipedia)

E10_JA_2/08 4 The Thinking of an Inventor It was well publicized that Thomas Edison had tried unsuccessfully more than twenty types of filaments in his efforts to invent a long lasting electric light bulb. After he finally invented the light bulb, and during a press conference, a young reporter asked him: Mr. Edison, can you comment on the more than 20 times that you failed to discover the light bulb? My young man, Edison replied, I did not failed 20 times; I simply discovered twenty ways not to built a light bulb I simply discovered twenty ways not to built a light bulb

E10_JA_2/08 5 Design: Noun Verb Design: Noun Verb 1. a plan 2. a project 3. a plan to work from. from. 4. a sketch to work from 5. a creative activity To plan by drawing the outline To plan by drawing the outline To sketch To sketch To contrive To contrive To project with an end in view To project with an end in view To form an idea To form an idea

7 Paper Clip / Zipper. Function, Simplicity, Cost (the most celebrated designs)

E10_JA_2/08 8 Modeling/Prototyping.

9 Dish maker prototype “…sure it looks like a big metal piece of scrap with lots of exposed wires and a power strip, but it makes dishes. “…sure it looks like a big metal piece of scrap with lots of exposed wires and a power strip, but it makes dishes.. ……”. ……”

E10_JA_2/08 10 What is Design? “Design is the decision making process by which: “Design is the decision making process by which: information (an idea) is transformed into an outcome, a product or service.” information (an idea) is transformed into an outcome, a product or service.”

E10_JA_2/08 11 The Engineering Design Process It is a process It is a process 1. Team Work Team organization Team organization Multi-tasking Multi-tasking Brainstorming Brainstorming 2. Several steps 3. “Value-add” in each step 4. Inputs and outputs 5. Schedules

E10_JA_2/ ID Need The Steps of the Design Process. The Steps of the Design Process. 2. Define Problem 3. Search 10. Communication 9. Specification 8. Test 5. Alternative solutions 6. Design 4. Constraints 7. Development

E10_JA_2/ Identify the need Who ID’s the Need? Who ID’s the Need? In General: 1. Local, State and Federal Government. 2. Market. 3. Individuals.

E10_JA_2/ Define the Problem What do we have to do? What do we have to do? What is needed? What is needed? Who is going to use it? Who is going to use it? Where would it be used? Where would it be used? How would it be used? How would it be used? …….. ……..

E10_JA_2/ Research - ID the Need - Define problem - Research 1.Material search and acquisition: 1.Technical information about it, 2.List of materials, 3.Properties of, name of supplier, 2.Quantity, Quality 1.Supplier, etc. 2.Tools and equipment used in the project: search and acquisition or build. (including testing devices) 3.Research about the engineering principles applicable to the project: 1.Theory, 2.Formulas for calculation, 3.How do they relate / help your project. 4.Technical reports from previous products.

E10_JA_2/ Constraints Constraints are limitations 1. Safety issues 2. Environmental issues 3. Other Governmental regulations 4. Cost issues 5. Production issues 6. Packaging and Transportation issues …and of course issues of “Engineering Principles ”

E10_JA_2/08 17 Sketching

E10_JA_2/08 18 Brainstorming A method of generating ideas 1. No Criticizing 2. No Limit 3. No Restrictions 4. No Dismissing 5. No Shame 6. No Boundaries 7. No Holding back The Seven Rules of Brainstorming

E10_JA_2/08 19 The Engineering Design Process 1. Understand the Need 2. Problem Definition 3. Design to constraints Now is Time for Now is Time for ideas ideas solutions solutions

E10_JA_2/08 20 The Engineering Design Process Remember… …design has many solutions… Collect as many ides as possible without criticizing, evaluating, limiting new ideas. Quantity is of essence

E10_JA_2/08 21 Solutions/Implementation/Evaluation After all ideas have been collected, its time to evaluate and select the promising ones. Then: After all ideas have been collected, its time to evaluate and select the promising ones. Then: fail pass fail pass Design Test Develop To MFG Specs
