Step 2.3.2 - work step in the VDI 2221


Overall employment measures contained in the 2221 VDI consists of 7 (seven) phases, which are grouped into 4 (four) phases, namely:


1. Translation Task (Clarification of Task)


Translation of this task includes information on problems and constraints faced. Then compiled a list of requirements regarding the draft will be made.


2. Determination Concept Design (Conceptual Design)


Determination Concept Design work includes three steps, namely:


2.1 Defining Functions and Structure.


2.2 Finding Solutions Principle and structure.


2.3 Describing a variant that can be realized.


3. The realization of the design (Embodiment Design)


In realization of this design begins by decomposing the design in the modules is followed by the initial design and the design finished.
4. The Design Details (Detail Design)
Detailed designing is the design process in the form of images. Which includes images and detailed images composed including parts lists, material specifications, tolerances and many others. In this phase all the work so that manufacture of the product can be documented by the operator or engineer implemented other appointed.
Overall employment measures contained within the VDI 2221 consisted of 7 (seven) phases, the presence of 7 (seven) the results of the work.
The seven steps are:
2.3.2.1 Translation Task (Clarification of Task)
In step translation work is done The task formulation and a list of requirements will be adjusted with the consumer and the designer, who is expected to be fulfilled by the final solution. This information would be a reference preparation of specifications.
Specification is a list that contains terms that are expected to be fulfilled by the concept of being manufactured.
To facilitate the preparation of specifications, it can be done by reviewing certain aspects, such as aspects of geometry, kinematics, force, energy and so forth. From these aspects can described the relevant terms, then formulate the tasks that must be faced, so to be in accordance with a designer sunglasses.
This specification is an important document which became the basis to carry out other work steps. Therefore, the specification should always be reviewed and updated.
