can lead to a solution. Paint sticks to a house
through the adhesion between the paint
and the siding. Maybe a material can be
mixed with the paint that causes the paint
to lose adhesion when a special chemical
is applied. At repainting time, the chemical
can be sprayed on to loosen the paint. The
paint can then be easily removed from the
siding.
Rough Sketching
Once designers have conceived of a
number of ideas, they must record the
ideas. The most common recording method
is to develop rough sketches of the prod-
ucts, structures, or system components. See
Figure 10-9. These sketches are as much a
part of the thinking process as they are a
communication medium. Designers are
forced to think through concepts such as
size, shape, balance, and appearance. The
sketches then become a library of ideas for
later design efforts.
Figure 10-8. A classification chart divides the design problem or opportunity into
segments to develop solutions more easily. This type of chart is called a tree chart.
