    topaz jewelry wholesale High school universal technologies refer to information technology, broaden, and distinguishing with professional technology, which are widely used, are technologies that are widely used in daily life and have extensive migration value for the development of students in daily life. Let ’s take a look at the high school universal technology design plan with Xiaobian.
    The design plan for making convenient small stools:
    The concept of design problem:
    It design a small stool that is suitable for children to use and carry convenient when outdoor activities. Features of portable stools: simple, stable, easy to make; self -heavy, small volume, and easy to carry; cost is not higher than 5 yuan.
    The detailed design scheme and description:
    The design and connection methods that meet the requirements are designed.
    comparative and decision -making of schemes:
    Considering that the small stools produced should be suitable for mass production, five plans for making materials with five splints are selected. These five schemes were screened again according to the design requirements, and three solutions were selected at the end.
    Is when multiple design schemes are generated, these schemes are screened according to certain principles.
    The test, assessment and optimization:
    The main testing design scheme is feasible, conduct various tests, assessments, and optimize design schemes and improve product prototypes. Based on the factors in various aspects, and a comprehensive assessment of the three design schemes and products. The three schemes are evaluated as follows.
    In testing and evaluation, in comparison design requirements, C3 is an ideal design solution in a solution to use the five splint materials.
    c3 design three views.
    The product prototype was made according to the drawing of the drawing. After seeing several processes such as sawing, cutting, planing, grinding and assembly, the product prototype of product prototypes produced by the C3 solution is designed.
    Portable small bench Instructions: Product introduction: This product is a portable bench designed for children to go out. It is light, small, convenient to carry, and easy to disassemble and assemble.
    The product composition: hollow stool surface, stool feet (two pieces).
    Technical indicators: Stool height: 16.5cm.
    The stool mass: 350g.
    This area: 432cm2.
    Ap use: first remove the two stool feet from the stool surface, then convert the joints, insert them, and then insert the inserted stool feet into the grooves of the stool surface, and use hands or hands or or Other objects make the stool feet and the stool surface completely tight.
    If Note: (1) After use, remove it in time and put the stool feet back into the hollow box -type stool surface. (2) Do not place overweight objects (greater than 42kg) on ​​a small stool to avoid bending and deforming the stool surface. (3) Avoid the sun and rain for a long time to prevent the material from bursting or moisture. Scope of application: children aged 5 to 9.
    MEMC technology production method
    . Developing design solution: (proposed design requirements)
    1) The design is innovative.
    2) Environmental materials and waste recycling are used as much as possible.
    3) There must be design patterns.
    4) The connection between the components is tight and firm.
    5) The work has a certain strength and stability.
    6) Works have certain innovation and practicality.
    7) The production process is reasonable, the division of labor is clear, the tools are used properly, and the safety is safe.
    8) Whether it is beautiful, practical and novel.
    . The general step of making models:
    1) Select the right material. (Requires environmental protection and waste recycling as much as possible)
    2) Prepare appropriate tools and processing equipment according to local conditions.
    3) Create a line according to the design pattern.
    4) Saw, cutting and cutting materials for materials.
    5) assembly.
    6) Surface processing of the model.
    7) Evaluate the appearance and color of the appearance; test and test the structure and function of the product, whether it meets the design requirements.
    8) Modify the design plan and make a model.
    . The production model (operation essential)
    The emphasizes the safety of the tools such as sawing, hammer, pliers, diamonds, etc. During the production model, students are required to use the tools safely.
    . Display models
    The models that students make good are compared and evaluated, and students communicate with students. Select the works for students to learn and display.
