What are some of the works that have a technological general purpose technology? What is the production process?

High school general technology refers to the information technology outside, the broader, embodies the basic and universal and differentiated from the professional technology, is widely used in daily life, the development of the majority of students with a wide range of migration value. The following and I take a look at the high school general technology design program.

Make portable small stool design plan:

Design problem conceptualization:

For the children to design a suitable for them to use in outdoor activities and portable small stool it. Portable stool features: simple structure, solid, easy to make; light weight, small size, easy to carry; cost is not more than 5 yuan.

Detailed design program and description:

Designed to meet the requirements of a variety of materials, structures and connections.

Comparison and decision-making:

Taking into account the fact that the produced small stool should be suitable for mass production, five options were chosen with five plywood as the production material. And according to the design requirements of these five programs were screened again, and finally selected three programs.

When more than one design program is generated, based on certain principles, these programs are screened again.

Testing, Evaluation and Optimization:

Mainly examining whether the design solutions are feasible, conducting various tests and evaluations, as well as optimizing the design solutions and perfecting the product prototypes. Taking into account all aspects of the factors, a more comprehensive evaluation of the three design solutions and products. The three programs are evaluated as follows.

After testing and evaluating against the design requirements, C3 is the more desirable design solution among the options using five plywood materials.

Three views of the design of C3.

Product prototyping was carried out based on the machining drawings produced. After several processes such as sawing, chipping, planing, grinding and assembling, the design was created to produce a process diagram for producing a product prototype of the C3 solution.

Portable small bench instruction manual: Product Description: This product is a portable small bench specially designed for children's outings. It is light in weight, small in size, easy to carry, and easy to disassemble and assemble.

Product composition: hollow stool surface, stool footboard ( two pieces ).

Technical indicators: stool height: 16.5cm.

Stool quality: 350g.

Stool surface area: 432cm2.

Methods of use: first, take out the two pieces of footboards from the surface of the stool, and then align the slots and plug them together, and then insert the inserted footboards into the grooves of the surface of the stool and make the footboards and the surface of the stool completely close to each other by using hands or other objects. Then insert the inserted footboards into the slots of the stool surface, and use your hands or other objects to make the footboards and the surface of the stool completely tight.

Precautions: (1) After use, disassemble the stool in time and put the footboard back into the hollow box stool surface. (2) Do not place heavy objects (more than 42kg) on the stool to avoid bending and deformation of the surface. (3) Avoid prolonged exposure to sun and rain to prevent the material from cracking or moisture. Scope of application: 5~9 years old children.

High school general technology production method

I. Develop a design program: (put forward the design requirements)

1) first design, the program is innovative.

2)Use environmentally friendly materials and waste recycling as much as possible.

3)There should be design drawings.

4)The joints between the components of the work are tight and strong.

5)The work has a certain strength and stability.

6)The work is innovative and practical.

7)The production process is reasonable, the division of labor is clear, and the tools are used properly and safely.

8)Whether it is beautiful, practical and novel.

Two, the general steps of making a model:

1)Choose suitable materials. (Require the use of environmental protection and waste recycling as far as possible)

2)According to local conditions, prepare appropriate tools and processing equipment.

3)Scribe the lines according to the design drawings.

4)Process the material by sawing and cutting.

5)Assembly.

6)Surface treatment of the model.

7)To comment on the appearance of the shape and color; to inspect and test the structure and function of the product to see if it meets the design requirements.

8)Modify the design scheme and make the model.

Three, making a model (operation essentials)

Emphasize the process of making a model to remember the safety of saws, hammers, pliers, drills and other sharp tools, students are required to be able to use tools safely.

Four, show the model

The students will do a good job of comparing and evaluating the models, students to exchange, selected works for students to learn and display.
