  • CHAPTER III CONCEPT DESIGN

    Designing Work Table, adjustable height

    (Height Adjustment Table)


    3.1 Duties

    Designing a Work Table, which could give comfort to the wearer.


    2.3 Translation Task (Clarification of Task)

    3.2.1 Background Design

    In general, people who work in offices spend more time behind a desk. One thing that is done routinely for years - years that surely lead to saturation.

    But on the other hand, the demands of the workload often makes an employee can not take a break and without conscious waktupun passed quickly.

    Departure from the mentioned problems, the authors design a desk that used to keep the wearer comfortable does not feel tired as this may affect the working produktivas. Here functions are preferred, then a design to follow the function, though convenient to use the desk to be adjusted with the working atmosphere had to be done the wearer to support their work.



    3.2.2 List of the Will

    Before we reach the specifications, we do not yet know the outlines of how the form of an adjustable desk height and what will be achieved with the existence of such a desk.

    Therefore compiled a list of wishes. List will be listed first and then randomly arranged in a systematic and ultimately included in a format called specifications.

    The first stage collected the desired ideas, the situation is still not regular, those ideas are as follows:



    a. Table convenient to use.
    b. Adjustable table height.
    c. Easily assembled and disassembled.
    d. Save space, the table does not take up much space.
    e. Ancillary components are easily replaced, compact and lightweight.
    f. Construction cost is not expensive.
    g. In making a lot of absorbing labor.
    h. Dependence on foreign technology to a minimum.
    i. Can be made in bulk.
    j. Forces and moments is used as efficiently as possible.
    k. In the attempt is not too complex.
    l. Relatively easy operation.
    m. Can be operated by one person.
    n. Safe for users.
    o. Maintenance is easy.
    p. Meet the criteria of beauty.
    q. Can be developed as needed.
    r. Easy to move, move.
    s. Dibengkel medium can be made.
    t. In the event of damage can be repaired in place.
    u. Framework must be robust.
    v. Resistant to corrosion.
    w. Materials available in the country.

    All data related to the task, namely solving goals, characteristics that must be owned, definition fully and clearly the will of the list

  • 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.

  • abstraction and formulation


    Once the specification is obtained, then the measures of abstraction and formulation, which aims to determine which parts of the specification which is an important part and are generally accepted.


    During the steps of abstraction and formulation, the important thing to note is that distinguishes a requirement, whether as a demand (Demand) or desire (Wishes)


    Demand (requirement) is requirements must be fulfilled in every condition, or in other words if the conditions are not met then the design to be false / failure.


    Whises is desired requirements when possible. For example, a requirement which requires high cost, without giving effect great technique, so these requirements can be removed / ignored.


    This made the formulation of action steps that will be adjusted with the consumer and / or part wishes Production Planning (Product Planning Department)


    The works performed include:


    a) Gather information / data associated with the planning, checking any constraints faced.
    b) Checking the will-the will of others who can support their work.
    c) Adding a specific will of the company
    d) Formulate a task that faced so be in accordance with designer sunglasses.
    The work is the list obtained by the Will / requirements list. This will list should not be bound by the solution (the solution)
    List of the will is an important document, a basic step in executing other work. Hence the will of the list should always be reviewed and updated. Important discoveries may arise in the design process as a result of modifications or additions to the list will.
    The importance of the list will cause the handle must be orderly and systematic. List of the will which has been handled regularly and systematically in a format called specifications.
    STEP 2 After specifications are obtained carried abstraction and formulation.
    The purpose of abstraction is to determine which parts of the specification which is an important part and are generally accepted.
    Abstraction and formulation will make it easier to determine the functions and structure functions.
    Abstraction and the formulation is as follows:
    1. Desire / whises omitted.
    2. Imperatives / Demands that does not determine the function of temporarily discarded.
    3. Quantitative scale was changed to a qualitative scale.
    4. Formulate abstraction 1-3.
    5. Formulate a solution abstractions 4
