           16.2.8 Conceptual Design

                       After completion of techniques such as QFD, we have a strong understanding of the customers’ prod-
                       uct requirements. The problem is defined in a written problem statement or product design specifica-
                       tion, and the design team is finally ready to brainstorm its initial concepts. It is important to consider
                       all options for each of the product’s functions. What are my options for turning my device on? Should
                       it use a lever, button, sensor, or timer? What about voice activation? How should information be
                       displayed? Does it require a gauge, light-emitting diode (LED), buzzer, or synthetic speech?

                       Functional Decomposition.  Functional decomposition is a method of exploring many design
                       options for each product function. Figure 16.7 shows the overall system diagram for the toaster oven
                       example. Inside the box is the overall function of the product. At the top of the box, there are the
                       objects with which the toaster oven will interface. It must accept pans and trays and sit on a coun-
                       tertop or be installed below an upper cabinet.
