1.1. Justification of the creative project

Justification of the problem and need

The apartment in which we live, work and relax should be comfortable, cozy and, of course, beautiful. To achieve this, there is no need to spend a lot of money. To do this you need to do a lot with your own hands.

The main thing about this project is that the product can be made independently. When choosing this project, we took into account following points.

In the process of making a chair, acquired knowledge, skills and abilities in the field of mathematics, physics, chemistry and technology are used.

Making a chair helps to consolidate previously studied material on such topics as “Marking”, “Drilling”, “Furniture repair at home”.

The equipment of the training workshops makes it possible to carry out this project, this work not dangerous. During the process, you can become familiar with interior design technology and acquire furniture repair skills. By making such a chair, you can make a personal contribution to the decoration of your apartment by making a nice gift for your parents.

When making a chair, precision and accuracy are required.

Objective of the project - Develop a chair manufacturing technology, study the literature on this issue and manufacture the product.

The product must meet the followingrequirements :

1. The product must be made carefully.

2. The product must correspond to the chosen style.

3. The product must be beautiful.

4. The product must be durable.

The product that I decided to make, as stated above, should be neat, beautiful and durable. I decided to make the chair from wood (chipboard).

1.2. History of the chair

The history of chairs dates back to ancient times. Even ancient people realized the usefulness and necessity of such a thing on which they could sit and relax. Chairs primitive man They were a flat stone with uneven edges. Subsequently, people began to improve the chair and added some details to it. Gradually he began to accept, albeit distantly, modern look.

In later times, chairs decorated precious stones and made from expensive materials have become a luxury item. The royal chairs (thrones) were hollowed out from a huge block of marble, inlaid with diamonds and other precious stones, and trimmed with gold.

Hunters and fishermen also use chairs, and their role can be played by a wide variety of objects: boxes, even stones, logs, etc.

Every home also has chairs. Their designs in different times were different and corresponded to different people's ideas about beauty and convenience. These were chairs from different varieties wood, ranging from cheap pine to extremely expensive mahogany. There are also several more popular modifications of the chair - armchairs, rocking chairs, sofas, ottomans. And although they look different, their purpose is absolutely the same.

In normal wooden chair the most commonly used designs are those with four legs, but you can find specimens that have only three legs.

4.The product must be durable.

4. Theoretical information

The product that I decided to make, as stated above, should be neat, beautiful and durable. I decided to make the stool from wood.

IN in this case It is best made from oak wood.

Oak is a deciduous ring-vascular wood species. Oak wood is characterized by high strength and hardness, resistance to rotting, the ability to bend, and has a beautiful texture and color. It is used in carpentry and furniture, plywood planing and parquet production; in wagon train and shipbuilding, as well as in agricultural engineering, in the production of stave blanks for barrels.

5. History and modernity

The history of chairs dates back to ancient times. Even ancient people realized the usefulness and necessity of such a thing on which they could sit and relax. The chairs of primitive man were flat stones with uneven edges. Subsequently, people began to improve the chair and added some details to it. Gradually it began to take on, albeit vaguely, a modern appearance.

In a regular wooden chair, the most commonly used designs are those with four legs, but you can find examples that have only three legs.

6. Bank of ideas

During the information collection process, a number of options were considered:

1 Make a banquette

2 Classic stool

3 Small bench

After considering the three presented options, studying their features, the need for materials and other components, a decision was made: to manufacture the “Stool” product, taking option number two as a basis.

7. Sketch development of the basic version

To decorate the stool and improve the aesthetic appearance, we decided to treat the legs of the stool with lathe. The legs are also turned on a lathe. They decided to make the stool cover from laminated particle board covering the edge with texture tape.

8. Product requirements

9. Design specification

10. Tools and equipment

When making a stool of the above design, it is necessary to use hand-held woodworking tools and equipment:

1. Carpentry workbench

2. Hacksaw

TABLE OF CONTENTS

1.Relevance of the topic.

Justification for choice.
My choice of product is justified by the fact that I really like furniture and like repairing it. So I decided to make my first product, a children's chair. There are a huge number of shapes, sizes and designs of highchairs, but I decided to make my own creation. I came up with the form myself. First, I drew a sketch, thought through all the dimensions, and then began to make drawings, after which I began the manufacturing process.
Goals and objectives.
When making my product, I adhered to the following goals and objectives.
Goals:

Aesthetic appearance.
- Manufacturability.

Practicality.
Tasks:

Increase your knowledge in the field of wood finishing.
-Improve ownership skills hand tools.
Originality and practicality.
My product is practical, it is original in that I made it myself: I came up with the shape myself, compiled the documentation myself, prepared the material myself, cut out the outline myself, connected and adjusted all the parts and elements myself. The finished product looks good as a high chair or gift. Manufacturing costs are not very high.

2.Historical information.

The history of the appearance of stool goes back to ancient times. Even the ancients realized the need for this object, on which one can sit comfortably. The chair of primitive man was a piece of fallen wood or a large stone. Chairs, like other luxury items and furniture, were trimmed with gold and made from especially expensive wood. Every home has chairs. Their design at different times corresponded different designs. These were massive chairs made of valuable wood, children's chairs, chairs for the sick and disabled. Time makes its own adjustments; nowadays chairs are made of light metal, plastic, as well as the well-known computer chairs. At all times, people have introduced something unusual into the design and design of chairs.

4.After work, disconnect the power tool from the power source.

9.Economic certificate.

In order to calculate the costs of making your product, you need to know the cost of all materials and electricity spent on its production.

I did not take into account the costs for:

Depreciation of equipment, as I worked in a school workshop;

Electricity, as they worked during daylight hours;

Payment for labor, since I did everything myself;

I also made the dowels myself, so I didn’t take their cost into account.

10.Environmental justification.

Products made from natural wood are environmentally friendly. They do not harm the environment and are completely recyclable. Small environmental problem can create the use of furniture varnish, but very little of it was used in the manufacture of this product. Therefore, we can conclude that the designed product is environmentally friendly, does not cause allergic reactions in humans and does not harm the environment.

11.Evaluation of work performance.

I believe that the manufactured chair meets all the requirements placed on it. It is small-sized, comfortable, durable, has a pleasant appearance and will fit well into the interior of a children's room. I think that I accomplished my goal well.

How the idea was born Many guests often come to our dacha and sometimes there are not enough chairs. In this case, you have to arrange random seats in the form of benches - this takes a lot of time, space and is not very convenient. Many guests often come to our dacha and sometimes there are not enough chairs. In this case, you have to arrange random seats in the form of benches - this takes a lot of time, space and is not very convenient. When the problem of choosing a project arose, I turned to my father, and he suggested a reasonable way out of the current situation with a shortage of seats, to try making folding stools.

Theoretical information When developing the project and constructing it, I relied on the principle of variability, unification and typification. When developing the project and constructing it, I relied on the principle of variability, unification and typification. I had to select proportions such as: stability, simplicity and convenience during assembly and disassembly, reliability during operation. To do this, I made templates from packaging cardboard according to the pattern.

Safety rules for cutting and cleaning surfaces

Self-esteem I independently made a multifunctional stool and prepared to defend a creative project. As production progressed, I became more confident working with power and hand tools. While developing design and technological documentation, I needed the help of a teacher, which I asked for and received. In the process of working on the project, I began to better understand drawing and perform many operations on a personal computer. The manufactured product turned out to be beautiful, comfortable and, of course, multifunctional. The cost of the stool was 641.5 rubles. In addition, the family budget saved 400 rubles on the difference between the costs of purchase and production. I coped with the task and I am pleased that it turned out to be an excellent multifunctional stool that my loved ones also liked. (see Appendix - reviews)

14. Quality control

The finished product meets the following requirements:

The product is made of natural wood. All parts are made carefully in accordance with the above technology. The product is a finished product. The appearance of the product makes a favorable impression.

15. Environmental justification

Products made from natural wood are environmentally friendly. They do not harm the environment and are completely recyclable. The use of furniture varnish can create a small environmental problem. But the use of laminated particle board nullifies all attempts not to disturb the environmental situation

16. Economic justification

For the manufacture of product parts you need 0.02 cubic meters. meter of wood.

1 cu. A meter of oak wood costs 6,000 rubles.

0.02 m3 x 6000 rub. = 120 rub.

When drilling on a VSN machine for 20 minutes, the following electrical energy was consumed:

0.4 kW x 0.34 h = 0.136 kW x h

0.136 x 1.51 rub. = 0.21 rub.

Upon completion of assembly, the product is coated with furniture varnish. 0.2 kg consumed.

1 kg of furniture varnish costs 100 rubles.

0.2 x 100 = 20 rub.

The total costs for making a stool are:

120 + 20 + 0.21 = 140.21 rub.

The worker’s wages are approximately equal to the cost of materials and in the end the price of the stool will be 280 rubles.

There are things you can't buy

But you can make it yourself.

This is our elegant stool; it is durable, light, comfortable, beautiful and safe.
