Chapter 10 Developing Design Solutions
205
Technological devices are designed
to meet identified problems and oppor-
tunities. See Figure 10-1. These prob-
lems and opportunities can be either of
the following:
System-design problems and
opportunities.
Product-design problems and
opportunities.
No matter what the area, though, develop-
ing design solutions involves three major

steps. We will discuss those steps after we
differentiate between system design and
product design.
System Design
System design deals with the arrange-
ment of components to produce a desired
result. For example, automotive brak-
ing systems are a result of system-design
efforts. Look at the drum brake system
shown in Figure 10-2. This design brings
Figure 10-2. This brake system was the result of system-design efforts.
Pressing the brake
pedal causes the
mechanical linkage
to move the piston in
the master cylinder.
The hydraulic pressure the brake fluid
creates moves the piston in the wheel
cylinder out, forcing the brake shoe
against the brake drum in the wheel.
The moving piston forces
the brake fluid out of the
cylinder.
Figure 10-1. Designers create both systems and products.
