下面以大家熟悉的塑料暖水瓶产品为例,进行功能定义,功能整理和功能重要度评价。 1.功能定义 首先列出所选对象(如暖水瓶)的名称(见表6—1中第一栏)。然后按照对象提供的功能进行功能定义(见表6—1中“功能定义”一栏)。 对象提供的功能可能是一个,也可能是两个或多个,提供几个功能,就定义几个。 2.功能整理 按照功能之间的系统联系关系,列出暖水瓶的功能系统图(见图6—1)。功能系统图的绘制说明如下:
In the following, we will use familiar plastic water bottle products as an example to carry out functional definition, functional arrangement and evaluation of functional importance. 1. Function definition First, the name of the selected object (such as a thermos bottle) is listed (see the first column in Table 6-1). Then define the function according to the function provided by the object (see the “Functional Definition” column in Table 6-1). The function provided by the object may be one, it may be two or more, provide several functions, define a few. 2. Functional arrangement According to the system relations between functions, the functional system diagram of the thermos bottle is listed (see Figure 6-1). The functional system diagram is drawn as follows:
