To make a good design, it is necessary to follow a procedure given by the characteristics and functions of an objet o.
understand the different uses for functions that can provide the object, and features the qualities you may have.
The function of the object changes as the user's perspective and may even have more than one function.
is important to consider that an object does not always fulfill a unique function, but may serve several, one which is preferred for the context in which it is. Example
objects whose function changes depending on the user:
study found similar products on the market
This phase of work is the study of similar products are present in the market, which involves looking at its and functions use.
As part of the design process of an object, you need to know and consider as "models", similar objects on the market, with analysis of them finished.
Under certain points of view as
• Specifications • Aesthetics
• Quality
ecological contribution
• • Your price
• Material
• Functionality • Ergonomics
Sample comparison of two objects that exist in the market made by another group:
Develop possible solutions to your specifications
The technical specifications are a set of characteristics and qualities that presents an object that determines its operation so that the user needs to know to make good use of object technology. For example a vacuum
brings a manual for use in
include technical specifications for connection to the grid of our house such as cleaning, caring for, care in use, such as saving, and more.
The technical specifications of an object are determined after meeting user requirements. These will influence the design, as a way to specify the characteristics that should include our object when constructed.
Another point to consider: are taken into account the principles of object technology to design clear, these are: • Aesthetic
• Ergonomics • Safety • Ecological
functionality
• What else includes technological design of an object?
The design must include a graphic representation of the object, ie a format with a picture that represents a reliable and accurate, for it is carried out a series of rules to draw, this is known as technical drawing. (What we have been working all year classes) Learn to choose materials
When referring to material that makes use of man, we must mention the
qualities that make a material more suitable than another, and to differentiate them. It is necessary always to have a concept of each material, for use at the time of choosing one for a particular purpose.
In many cases you had a solid material in your hands, and I have wondered what this material has special properties to build this object?.
Activity 1: Investigate the mechanical properties of materials
Unit: TECHNOLOGICAL PRODUCTION OF AN OBJECT
At this stage of technological object the sequence of activities to reach the project he is
Planning is a process that is characterized by the interdependence of each of its components or stages.
In the production of a technological object are involved various stages, which have a close relationship with each other, depend on each other. In planning the production of this item includes the following steps:
1. Description of tasks involved in production.
2. Organization of work.
3. Calculating production costs.
4. Determination procedures.
operations can defined as a task management of production, ie properly arranged in each stage of production so as to provide a better way of goods or products that are built.
Identification of materials, components and instruments in the context of the project
order to work effectively in the development of an object, you must have a good
knowledge of the properties of the materials to be used.
The use of materials also involves knowing manipulation, these are:
• Know how to cut, fold or glue.
• What techniques are most appropriate to use different materials.
• What are the possible combinations between them.
Each of the materials used, by its nature, involves the use of specific tools.
• Know the safety rules that work proceed in the most appropriate guarding the integrity of the people doing the work and those around them. 3 areas are considered important as cleanliness and order of space, use of tools such as wearing gloves etc. and lens material handling.
Activity: Research tools (name, function and usage) are used to working with different types of wood.
Each time we make a plan operations, we must take into account where we will draw the materials and tools or machinery, if necessary.
Prior to the completion of work there is to know what you want to build, then you have to design it and find the most appropriate materials and tools, we must also bear in mind how much money they should have. Only then one can make a list of construction tasks.
After coordinating the times of each task in the production should address some important issues that we need to know about the production of our object. These are:
• Know and determine if we have the capacity to carry out the object.
• Know and to evaluate the task falls to the suppliers of materials and tools
.
• Know and identify all those needs that people have
responsible for developing the project.
• Have knowledge of management of time it takes for each task in the process, in terms of: start time and end time.
production costing.
Now should you make that project budgets are going to do, that is, they must anticipate the costs of materials, workmanship costs and other expenses demanded by the social construction of technology, such as electricity, wear tools, papers, envelopes, transport, sometimes renting a room tax, etc.. Table
budget
Learning the organization of jobs
The organization of the workplace is the setting of major operations within the process of implementing the technological object.
consists of several tasks, which must be positioned so that avoid spending time and energy between a job and another. For example, if a job comes from sticking a piece and the next as the embedding, these positions should be very close, because otherwise the piece would not be glued in good condition.
In general, jobs are divided into groups with tasks ordered and sequential.
diagram What is the process?
is an outline detailing the tasks in sequential order and the movements to be performed during operation, for a technological object.
The process diagram is very useful for planning the construction of a technological object and know how much to delay the execution itself.
Development of a schedule Gantt (Gantt chart)
To develop a schedule is necessary to have a list of tasks sorted and know the approximate time it takes each of them. With all that is necessary to set the time for different tasks can be days, weeks or months.
Example of a Gantt chart of a process of producing a decorated cardboard box
Activity:
According to the request of the teacher designs and constructs an object using this If wood as main material, and applying all previous stages in the development of a project.
Then your schedule for the preparation of the report of the design and production units
Guideline 1. Home
2. Problem: drafting of the problem, the need to generate, identify the type of user.
3. Technological solution and justification: write the solution describing the object and why I chose also to mention the technological principles (ergonomics, aesthetics, environmental safety)
4. Object Design: draw the sketch with color, isometric views and do not forget the corresponding dimensions.
5. Production:
identify
• Materials • Tools
• Safety (what actions should be taken into account in handling the materials and tools)
6.
• Budget Planning: Using the example table
guide
• Gantt Chart
