Letter the names of the major components of the fi nal design in Problem 7.17.

Problem 7.17:

Evolve a design through three stages of refinement. First, generate 10 rough, ideation sketches, showing different design ideas. Use techniques outlined in Problems 7.15 and 7.16, and sketch on plain or grid paper. Spend about three minutes on each ideation sketch. Pick the three best designs and refi ne them, spending about 10 minutes on each sketch. Finally, pick the best design and spend about 30 minutes creating a detailed pictorial sketch. The fi - nal sketch may combine ideas from all three of the previously sketched designs.
Problems 7.15 and 7.16:

Problems 7.16:

Create 10 designs as you did in Problem 7.15, but instead of developing each new design from the original image, evolve the design from one sketch to the next.

Problem 7.15:

Using one photograph from those gathered in Problem 7.12, create 10 alternate designs of the object with tracing paper. With each sketch, trace most of the features as they are in the image, but change some to create a new design.

Problem 7.12:

Gather real examples, computer images, or magazine pictures of common objects. Have the objects vary in complexity of form. Some should have only simple, planar features, while others should be curved, sculpted surfaces. Some ideas are motor vehicles, farm equipment, household appliances, aircraft and nautical vessels, computer equipment, audio/visual equipment, furniture, lighting fi xtures, sports and exercise equipment, hand tools, and stationary and hand-held power tools
