1. Prototypes

2. Welcome to Innovations in Engineering! Please get your lap top and return to your seat. Lap top should remain closed. On a blank piece of paper, please answer the following questions: What is a prototype? What is a prototype? Why prototype? Why prototype? ????????????

3. What is a prototype? Why Prototype? According to Wikipedia. com, a prototype is : “ an original type, form, or instance of some thing serving as a typical example, basis, or standard for other things of the same category.” According to Wikipedia. com, a prototype is : “ an original type, form, or instance of some thing serving as a typical example, basis, or standard for other things of the same category.” While working in information systems, Engineering prototypes are used to identify and validate the design requirements of a problem. Prototyping gives a good representation of what a possible solution could be.

5. Types of Prototyping Cosmetic Research Throwaway Functional/Evolutionary

6. The Prototype Design Loop First, we need to find out what the “scope” is or what the breadth or opportunity to function. First, we need to find out what the “scope” is or what the breadth or opportunity to function. Next, we must define the requirements that must be met. Next, we must define the requirements that must be met. Now we begin to design Now we begin to design Once we have a design, we build off it. Once we have a design, we build off it. We demonstrate or try our design to see if the design fulfills all design requirements. We may need to go back to the design segment of our loop, or back to the prototyping stage if requirements are not fulfilled.

Once we have a working model, we may then demonstrate Once we have a working model, we may then demonstrate

7. Does this remind you of anything? The Technology Design Loop!

8. Prototyping Our CO2 Dragsters! As part of the requirement for this unit, you are to build a prototype of your CO2 dragster. We will be using Styrofoam blanks that are the exact size as the block of wood you will use for your final dragster.

You will be need to use tools to create your prototype, thus we will be working in the back lab. You will be need to use tools to create your prototype, thus we will be working in the back lab.

9. The StyroDesigner We will primarily be using the StyroDesigner’s or simply a hot wire cutter to transform our Styrofoam blanks into prototypes. Before we get to working, we must go over some safety. We will primarily be using the StyroDesigner’s or simply a hot wire cutter to transform our Styrofoam blanks into prototypes.

10. Hotwire Cutter Safety All students must wear safety glasses while in the lab All students must wear safety glasses while in the lab When using the hotwire cutter, make sure all loose clothing is secured. When using the hotwire cutter, make sure all loose clothing is secured. Do not touch the wire with bare hand. Do not touch the wire with bare hand. No more than 2 hotwire cutters per table.

11. Only use Styrofoam with the hotwire cutter. Only use Styrofoam with the hotwire cutter. Plan your work before you begin making cuts. Plan your work before you begin making cuts. Keep work area clean. Keep work area clean. Use in well ventilated area. Use in well ventilated area.

12. 10 Steps for Successful Completion of a Styrofoam Prototype 1. Cut Out Final Drawing/Pattern 2. Tape Pattern onto Styrofoam 3. Trace Pattern And Pierce Axle Holes 4. Trace CO2 Car Hole (End and Front View) 5. Drill Axle Holes 6. Cut Away Material From Side View 7. Tape Material Back On 8. Cut Away Material From Top View 9. Throw Away All Extra Styrofoam 10. Use Sandpaper To Smooth Edges
