1. Researching Designs

2. Engineering Design Process Step 2
After brainstorming, engineers begin the process of sketching and researching the potential design solutions.

3. Sketches
Drawings that can communicate the engineer’s idea to others.

4. Rough Sketches During or immediately following brainstorming
Need further development through research and analysis
A record of ideas in engineering notebook
Overall shape and size of product

5. Rough Sketches
Drawn to large or small scale
Thumbnail sketches
Provide a way for the engineer to communicate ideas

6. Rough Sketches
Allow others to see the ideas and offer suggestions to improve the design
Provide a concrete object to begin thoroughly researching the potential effectiveness of the design

7. Sketches are critical to begin formulating ideas for a design solution
Sketching Process
Sketches are critical to begin formulating ideas for a design solution
Four basic steps:

8. 1. Visualize the Solution
Appearance – three dimensions or six different sides
Functionality – the operation of the object

9. Combination of boxes, cylinders, cones, and pyramids
2. Block Out the Solution
Block out rough shapes
Combination of boxes, cylinders, cones, and pyramids

10. Isometric drawing methods make an object appear three dimensional
Show front, top, side views

11. Boxes
Cylinders
Pyramids
Cones

12. An outline is the basic shape of the object
3. Outline the Solution
An outline is the basic shape of the object
Lines drawn lightly, so they can be removed

13. 4. Detail the Solution
Details are the final component added to a sketch
Details are components of a design that were not part of the main shape that was blocked using boxes, cylinders, and other shapes

14. Sketching details along with the following research steps should be included in the engineering notebook.

15. Researching Ideas
Engineers look at how solutions have been solved in the past, review the mathematical and scientific principles used in a potential design, and survey potential users of the design.

16. Historical Research
Engineers look at how they can adapt current technologies and tools to solve the problem.

17. Methods: Historical Research Library research Field visits
Reverse engineering
Discussions with other engineers and professionals who use the technology
