Conceptual Design

As discussed in the design of this concept include, making the structure function, the search for solutions and the combination principle, the selection of a suitable combination, making the variant concept, and evaluation.

Determine Function and Their Structures

Overalle Function

After the main problem is known, then made the overall structure of the function. The structure of this function is illustrated by a block diagram showing the relationship of inputs and outputs. Input and output flows of energy, materials or signals.

Sub Function

If the overall function is quite complicated, it is a way to anticipate it is split into several sub-functions as in figure 2.4 below.

This division will provide benefits:

- Provide the possibility to conduct further search solutions.

- Give some fruit possible solutions with a combination of solutions see sub function.

At the time of making the structure function, must be distinguished between pure design (original design) with the redesign (adaptive design).

In pure design that became the basis of the structure and function is a major problem specification, currently in the design begins redesign of the structure functions are then analyzed.

This analysis will provide the possibility for the development of variations of the solution in order to obtain new solutions.

In this step done:

- Define the functions

At first the overall function, then if necessary function of the (sub-functions). This function is then compiled into the structure-function structure, which is the basis for seeking a solution principle.

The work is obtained:

One or several functions Structure / Function structure.

The structure functions are usually pictures or simple diagrams.
